How does an octopus reproduce? Reproduction in octopuses is surprising. Both males and females are relatively short lived, and die not long after reproduction. In the male, the third right arm is specialized for reproduction and is called a hectocotylus. He uses this arm to insert a spermatophore (sperm packet) into the female.Within a few weeks of copulation, the male dies. The female octopus can store the sperm and fertilizes her eggs once her den is ready.She will seal herself inside her den using rocks, and once the eggs are fertilized, she will lay anywhere from 20 000 to 100 000 of them in strings on the upper side of the den.oth males and females are relatively short lived, and die not long after reproduction.

- The hemlock woolly adelgid has a complex life cycle, involving two different tree host species as well as asexual and sexual life stages. On eastern hemlock, HWA produces two generations a year, an overwintering generation (sistens) and a spring generation (progrediens); these two generations overlap in the spring.

Definitions &Translations Since the reproduction is asexual, the newly created organism is a clone and is genetically identical to the parent organism. Organisms such as hydra use regenerative cells for reproduction in the process of budding.In hydra, a bud develops as an outgrowth due to repeated cell division at one specific site. These buds develop into tiny individuals and when fully mature, detach from the parent body and become new independent individuals.ince the reproduction is asexual, the newly created organism is a clone and is genetically identical to the parent organism. Organisms such as hydra use regenerative cells for reproduction in the process of budding.

Asexual Reproduction Many plants are able to propagate themselves using asexual reproduction. This method does not require the investment required to produce a flower, attract pollinators, or find a means of seed dispersal. Asexual reproduction produces plants that are genetically identical to the parent plant because no mixing of male and female gametes takes place.

Rhizopus Rhizopus species grow as filamentous, branching hyphae that generally lack cross-walls (i.e., they are coenocytic). They reproduce by forming asexual and sexual spores. In asexual reproduction, sporangiospores are produced inside a spherical structure, the sporangium.ome Rhizopus species are opportunistic agents of human zygomycosis (fungal infection) and can be fatal.

- No, angiosperms do not need water to reproduce. Bryophytes, or mosses, need water to reproduce-the sperm cells swim to the egg by following a trail of chemicals in the water.… Thus, mosses reproduce in wet, rainy seasons of the year.heir seeds develop without a protective covering of ovary wall. Conifers (like pines, redwoods, and fir), gingkos, seed ferns, cycadeoids, and cycads are gymnosperms. Angiosperms have to undergo a process called pollination before they can reproduce. Angiosperms have male sex organs called stamens.

1. Which one of the following is a green house gas? Carbon dioxide 2. The tallest living tree is Sequoia 3. Life cycle of a Bryophyte (moss). The moss sporophyte depends on the gametophyte and is not a free‐living independent plant. The spores form after meiosis and germinate to develop into male or female gametophytes. Moss sperm are produced from cells in the antheridia of the male gametophyte. The moss eggs are located at the base of the archegonia, on the female gametophyte. Each sperm has two flagella. Sperm swim to the eggs and after fertilization, the zygote develops into the sporophyte.

Plant-like Protists Plant-like protists that were reproduced asexually, grow from the spores off the parenting protist and begin to grow by themselves. Sexually reproduced protists are fertilized and released in a pod. When they are ready the protists leave the pod and grow (as seen in pink picture above).ome plant like protists such as Spirogyra reproduce through conjuation (shown right). Conjuation is a sexual way that simple protists reproduce. Spirogyra does this by by letting material transfer from one cell filament to another filament in another cell.

- What really happens is that the sporophyte grows out of the top of the gametophyte, so it looks like a headdress of some kind. In this image of stagshorn moss, the green leafy part is the gametophyte and the tall spindle on top is the sporophyte. The first thing bryophytes need to reproduce is water. Since they usually live in places that are moist at least some of the time, this isn’t really a problem for bryophytes. However, they still wait until a rainy period to reproduce, because they need water to carry sperm to the eggs. Bryophyte reproduction happens in two ways, like with other plants.

What is the life cycle of an angiosperm in simple steps? The angiosperm life cycle begins with a diploid (2n) flower on the mature sporophyte plant. Within the anther, the microsporocytes develop and undergo meiosis (reduction of chromosomes) to produce haploid (n) microspores. flower produces male spores inside its anthers and female spores inside its pistil. Spores de … velop into male and female gametophytes. Sperm enter an ovule through a pollen tube, and fertilization occurs.

Five Examples of Organisms That Use Asexual Reproduction Fragmentation and Blackworms. Many species of annelids (worms) reproduce via an asexual process called fragmentation. Included in this category of worms are California blackworms, or mudworms. These worms are hermaphroditic -- they have both male and female reproductive parts -- and can reproduce sexually.

- For example, Ascaris mate in the lungs, migrate to the bowels, lay their eggs, then head back to the lungs to mate again. I don't think a colonoscopy can get rid of the ones that are in the lungs mating when you have it. Just one example. Pinworms burrow under the skin, disappear, migrate and then resurface.

- Microspores (produced in a microsporangium) can develop into male gametophytes that produce sperm within antheridia. Because the gametophytes develop within the spores, they are not free-living as the gametophytes of other seedless vascular plants.s the spore germinates, it develops into a thin, filamentous stage called a protonema. As the protonema grows, it develops into a mature gametophyte with root-like rhizoids that anchor the plant and an erect, stem-like structure with whorls of leaf-like photosynthetic tissues.

Reproduction and life cycle in Ascaris lumbricoides Ascaris copulate in the intestine of man. During the process sperms are ejected by male into vagina of the female. These move in the uterus where fertilization occurs. While moving further the eggs become covered by a chitinous shell and an outer inegular albuminous coat.

- Most are colonial organisms whose polyps reproduce asexually by  budding, the buds develop into polyps which separate from the colony and live independently. Other species reproduce a sexually and sexually, some are hermaphrodite but in most species the sexes are separate. First, polyps bud to form a colony asexually. The polyps then give rise to male and female medusas which release egg or sperm into the water, the gametes fuse and produce zygotes that develop into free-swimming larvae called planulae.

A. Mitotic Activity/ how they reproduce? Asexual reproduction- Paramecium usually reproduces by splitting in two, forming two virtually identical individuals from one organism. Most ciliates divide transversely, splitting in two by pinching off in the middle of the long axis of the organism.. The macronucleus does not divide by mitosis, rather it elongates and

Brain coral fact file Coral colonies grow through a form of asexual reproduction known as budding, in which polyps divide themselves to form new polyps . Corals can also reproduce sexually by spawning, which in Platygyra daedalea involves the release of gametes into the water, for external fertilisation. Platygyra daedalea is hermaphroditic, meaning that each polyp produces both eggs and sperm.

What Is a Paramecium? Sexual reproduction (conjugation) Conjugation among paramecia is akin to mating. Forney said that there are two mating types for paramecia, which are referred to as odd and even. This reflects the fact that the mating types for various Paramecium species are denoted by either an odd or even number.

Common Types of Asexual Reproduction In animals, this can occur in two primary ways: through asexual reproduction and through sexual reproduction. In asexual reproduction, one individual produces offspring that are genetically identical to itself. These offspring are produced by mitosis. There are many invertebrates, including sea stars and sea anemones for example, that produce by asexual reproduction. Common forms of asexual reproduction include: Budding. In this form of asexual reproduction, an offspring grows out of the body of the parent. Hydras exhibit this type of reproduction. Gemmules (Internal Buds) In this form of asexual reproduction, a parent releases a specialized mass of cells that can develop into offspring.

How Do Pinworms Reproduce? Pinworms rely on sexual reproduction -- they are not able to produce offspring asexually. A male and female worm must be present to create offspring, which is not the case with all worms. Reproduction among pinworms is often a self-destructive act. Male pinworms forcibly inject genetic material into females, an act known as traumatic insemination, which can cause physical damage to the females' bodies.

Plant reproduction Vegetative reproduction involves a vegetative piece of the original plant (budding, tillering, etc.) and is distinguished from apomixis, which is a replacement for sexual reproduction, and in some cases involves seeds. Apomixis occurs in many plant species and also in some non-plant organisms.eeds generated by apomixis are a means of asexual reproduction, involving the formation and dispersal of seeds that do not originate from the fertilization of the embryos. Hawkweed (Hieracium), dandelion (Taraxacum), some Citrus (Citrus) and Kentucky blue grass (Poa pratensis) all use this form of asexual reproduction.
