Annelida - Segmented Worms Earthworms eat dead plants and animals. When they eat, they also take in soil and tiny pebbles. They take in nutrients from microorganisms in the material they ingest. Earthworms then excrete wastes in the form of casts. Casts are rich in nutrients like nitrogen, phosphorus, and potash.

Cuticle Of The Leaf: Function & Concept The cuticle is a waxy, water-repellent layer that covers all of the above-ground areas of a plant. It is secreted by the epidermis, the outer layer of the plant, and covers up any holes or chinks between the cells.

Earthworm An earthworm is a tube-shaped, segmented worm found in the phylum Annelida. They are commonly found living in soil, feeding on live and dead organic matter.Its digestive system runs through the length of its body. It conducts respiration through its skin.heoretical cladistic studies have placed them, instead, in the suborder Lumbricina of the order Haplotaxida, but this may again soon change. Folk names for the earthworm include dew-worm, rainworm, night crawler, and angleworm (due to its use as fishing bait).

- In botany, plant cuticles are protective, hydrophobic, waxy coverings produced by the epidermal cells of leaves, young shoots and all other aerial plant organs.Cuticles minimize water loss and effectively reduce pathogen entry due to their waxy secretion. cuticle /ˈkjuːtɪkəl/ , or cuticula, is a term used for any of a variety of tough but flexible, non-mineral outer coverings of an organism, or parts of an organism, that provide protection. Various types of cuticle are non-homologous, differing in their origin, structure, function, and chemical composition.

Cuticle Of The Leaf: Function & Concept The Cuticle and the Stomata. The cuticle is a waxy, water-repellent layer that covers all of the above-ground areas of a plant. It is secreted by the epidermis, the outer layer of the plant, and covers up any holes or chinks between the cells. This waxy layer keeps all of the plant's valuable water inside where it belongs. However, while the cuticle closes up any areas where the plant could lose water, it also closes up any place that allows the plant to breathe. Remember, plants are the reverse of us; they take in carbon dioxide and release oxygen. Plants rectified this problem through the creation of pores in the leaf called stomata.

- Structure. The primitive brain of the earthworm consists of two cerebral ganglia. Sensory nerves leave the brain and run forward to the first segment in the earthworm's body. The nerve cord travels from this first segment to the last.A fibrous sheath surrounds the nerve cord.hile humans and other vertebrates have a spinal column that runs down their back, or dorsal side, earthworms possess a nerve cord consisting of two strands that runs down their belly, or ventral side.

Recommended Thermostat Settings for Home Comfort During the warm weather, it is generally recommended that you set your home's cooling system to 78 degrees Fahrenheit when you are home. If you will be out of the house for four or more hours, consider raising the setting so the cooling system only comes on if the temperature tops 88 degrees Fahrenheit.ypically, adjusting temperatures 5 – 8 degrees (down in winter, up in summer) can help save energy if you are going to be away from home for several hours. Here are a few tips and benefits of a programmable thermostat from Energy Star:

What Advantages Does the Waxy Cuticle Provide to the Leaf? The cuticle is a multi-layer structure composed primarily of cutin, cutan, polysaccharides, lipids and waxes. On the inward-facing side of a leaf, the cuticle attaches to the epidermal plant cell walls, and on the outward-facing side, the cuticle forms a film or skin that covers the leaf surface.utin forms an insoluble hydrophobic barrier, which means it does not disintegrate by dissolving in water but remains in place to protect the leaves. Cuticle thickness varies, depending on plant type and the plant parts it covers. On leaves, the cuticle is 1/10 to 14 micrometers thick.

What Advantages Does the Waxy Cuticle Provide to the Leaf? The cuticle also works with the stomata to help complete photosynthesis. After the stomata open and carbon dioxide enters the leaf, the cuticle protects the mesophyll layer, which contains the photosynthetic cells that receive and process the carbon dioxide to manufacture glucose.The cuticle is translucent, so it does not block the sun’s rays from reaching the photosynthetic cells.utin forms an insoluble hydrophobic barrier, which means it does not disintegrate by dissolving in water but remains in place to protect the leaves.

Earthworm An earthworm has a double transport system composed of coelomic fluid that moves within the fluid-filled coelom and a simple, closed blood circulatory system. Chemical: In addition to dead organic matter, the earthworm also ingests any other soil particles that are small enough—including sand grains up to 1/20 of an inch (1.25 mm)—into its gizzard, wherein those minute fragments of grit grind everything into a fine paste which is then digested in the intestine.

earthworm dissection The earthworm takes in a mixture of soil and organic matter through its mouth, which is the beginning of the digestive tract. The mixture enters the pharynx, which is located in segments 1 6. The esophagus, in segments 6 13, acts as a passageway between the pharynx and the crop. The crop stores food temporarily. The mixture that the earthworm ingests is ground up in the gizzard. In the intestine, which extends over two-thirds of the body length, digestion and absorption take place. Soil particles and undigested organic matter pass out of the worm through the rectum and anus.

- Activity 23b.2Internal Anatomy To dissect the earthworm, you would lay it out in a dis-secting tray, dorsal side up, and hold it in place by pinning down its prostomium at the anterior end and also near its posterior end. You would make a shallow incision behind the clitellum just to one side of the mid-dorsal line.

- The earthworm has a hydrostatic skeleton, fluid that resists compression from external pressure. Each segment is filled with fluid and, during movement, the alternating muscle contractions force the hydroskeletal fluid toward its posterior end.arthworm movement begins with a contraction of the inner muscles nearest to the worm's head, setting off a ripple of contraction and expansion that propels the worm through the soil.

What Are the Seven Organ Systems of the Earthworm? Part of an earthworm's excretory system is directly connected to his digestive system, as the intestines pass waste through the anus and out of the worm.This poop is called castings, and it serves as a type of plant fertilizer. However, some of the waste is picked up by excretory cells and carried outward to the skin.n earthworm has a closed circulatory system that uses vessels to send blood through its body. There are five aortic arches throughout his body that serve as pumps. The dorsal vessels take blood from the back of his body to the front, and the ventral vessels take blood the other direction, from front to back.

What Is a Plant Cuticle? A plant cuticle is the waxy film or membrane that covers leaves and other dermal tissue on plant sections above the ground.Waxes and polymers such as cutin and cutan, which contain omega hydroxy acids, ester, epoxides, and hydrophobic aliphatic compounds, make up the cuticle. plant cuticle is the waxy film or membrane that covers leaves and other dermal tissue on plant sections above the ground.
