Pine nut Stone Pine cone with pine nuts — note two nuts under each cone scale. Pine nuts are the edible seeds of pines (family Pinaceae, genus Pinus). About 20 species of pine produce seeds large enough to be worth harvesting; in other pines the seeds are also edible, but are too small to be of notable value as a human food.

Different Kinds of Tree Cones Conifers, or cone-bearing trees, are mostly evergreen and have thin, spiky leaves called needles. Conifers include the pine, fir and spruce families.rees species in the pine family (Pinus spp.) are conifers with long flexible needles. Pine tree seeds are held in cones that vary widely in size depending on the species, but all are characterized by hard, woody scales attached to a central stem.

List of Pine Tree Species Names of the Pinus Genus Pine trees are all evergreens and possess needles as leaves and cones as part of their reproductive system. All pines are resinous Coniferous trees. Some Pine species grow as shrubs instead of trees.

- Pines (Pinus spp.) and spruce trees (Picea spp.) are evergreen conifers. Aleppo pine (Pinus halepensis) puts out brown, yellow or mostly green cones 1 1/2 to 3 inches long.he majority of conifers are monoecious, which means the male and female cones grow on the same tree, and some are dioecious, which means male and female cones are on separate trees. The male cones produce pollen and fertilized female cones produce seeds.

- No, not a fluke. Pineapple is a fruit and sometimes do have seeds. I'm not sure if the variety that is sold is suppose to be seedless, but I liken it to a seedless watermelon, sometimes I find a few seeds even in those. Maybe you got a variety of pineapple that was not seedless. Clicking the will recommend this comment to others.

- Conifers have two types of pinecones: larger, woody ones called ovulate cones and pollen cones, which function like sperm. Ovulate cones contain the ovule, much like an egg in reproductive terms. When the tree pollinates, the wind blows pollen from the pollen cone to the ovulate cone.

Pinus strobus The seeds are 4–5 mm (0.16–0.20 in) long, with a slender 15–20 mm (0.59–0.79 in) wing, and are wind-dispersed. Cone production peaks every 3 to 5 years. While eastern white pine is self-fertile, seeds produced this way tend to result in weak, stunted, malformed seedlings.Mature trees can easily be 200 to 250 years old.inus strobus grows approximately 1 m (3.3 ft) per year between the ages of 15 and 45 years, with slower height increments before and after that age range. The current tallest eastern white pines reach between 50–57.55 m (164.0–188.8 ft), as determined by the NTS—Native Tree Society.

- Scales of a Cone. Trees that grow cones are in a group called conifers. The cones of the conifers are very important because they are the place where the tree makes and shelters its seeds.Cones are made up of many scales.Scales are a kind of shelter for the seed.

What is the male gametophyte of a pine tree? Answers. Best Answer: pine tree represents the diploid sporophyte generation. By meiosis, the pine eventually produces male and female gametophytes. The male gametophytes of the pine are smallthey are the pollen grains released by male cones to be dispersed to female cones.The larger female gametophytes remain within the ovules of the female cones of the pine and are dependent on the surrounding sporophyte tissues for their nutrition.Source(s):he larger female gametophytes remain within the ovules of the female cones of the pine and are dependent on the surrounding sporophyte tissues for their nutrition.

Where Do Pine Nuts Come From? Yes, they do come from a pine tree! Pine nuts are an edible seed, found inside pine cones. Apparently, they are incredibly difficult to extract. Then again, shelling any nut is pretty labor intensive. Fortunately, you can buy pine nuts in a bag, ready to eat, at the grocery store!

Pine Trees Types White Pine. The white pine is a variety of tree that is hardy to plant in USDA growing zones 3 through 8 and prefers a moist, well drained soil. The tree grows to a height up to 80 feet with a 40 foot spread.White pine has blue-green colored needles that grow in clusters and produces 6-inch-long cone seeds.here are approximately 105 to 125 species of pine trees throughout the world. Pine trees are known for the needle foliage and cone seeds that they produce and are grown for landscaping purposes, timber products and for use as Christmas trees.

- This is a conspicuous group of woody plants commonly known as the conifers. The members of this group produce ovules that mature into seeds. These ovules and seeds are found on the upper surfaces of scale structures which often are clustered into cones.

Pine Pines have four types of leaf 1  : Seed leaves (cotyledons) on seedlings, born in a whorl of 4–24. 2  Juvenile leaves, which follow immediately on seedlings and young plants, 2–6 cm long, single, green or often blue-green, and arranged spirally on the shoot. 3  These are produced for six months to five years, rarely longer.

gametophyte A pine seed thus contains three generations of the pine plant: the seed coat that arises from diploid tissue belonging to the ovule, the haploid gametophyte tissue that will serve as a food reserve for the embryo after germination, and the diploid embryo itself. In angiosperms, the female gametophyte has evolved into an even more reduced form.

Pine Pollen Benefits, The Superfood from the Pine Tree The pine tree pollen produced does not come from the female pine cones most people are familiar with, but from the male cone or catkin, a softer spiky shoot that buds every year in early spring. This is what creates the pollen used to fertilize the growth of female pine cones.

Why Do Pine Trees Have Cones? Pine cones are more than a decorative holiday wreath or centerpiece insert. Cones are the essence of life for new forest growth. These protective seed pods are necessary to the production of future pine trees. The woody cones are food for birds and animals, which in turn help spread the fertile seeds throughout the forest.

- Answer: Maine designated the white pine cone and tassel as its state flower. The pine cone is the female structure that bears the seeds, and the tassel is a smaller cone-like structure that produces pollen. Botanically, both the cone and tassel are not considered flowers, but are known as strobili.

Pine Pines are gymnosperms. 1  The genus is divided into three subgenera, which can be distinguished by cone, seed, and leaf characters: 2  Pinus subg. Pinus, the yellow, or hard pine group, generally with harder wood and two or three needles per fascicle. 3  Pinus subg. Ducampopinus, the foxtail or pinyon group. 4  Pinus subg.

How Do Pineapple Plants Reproduce? The seeds of a pineapple are viable but notoriously slow to germinate and often will not sprout at all. Because of this, only select growers grow pineapples from seed. The seeds themselves are found in pollinated plants and appear within the soft flesh near the tough outer skin of the fruit.Plant pineapple seeds in well-drained soil that is kept moist by frequent watering and misting.lips. The pineapple produces several plantlets near the base of the fruit called slips. These slips appear as red or green outgrowths along the stalk. Pinch them away from the main plant and plant them in the ground at a depth of between 3 and 6 inches.

Conifer The Conifers are cone-bearing seed plants. Most are trees; some are shrubs. They are formally the Division Pinochet or Coniferous. Conifers are Gymnosperms. They are cone-bearing seed plants with vascular tissue; all living conifers are woody plants, the great majority being trees. Living conifers are all in the order Pinales.

Eastern White Pine Pinus strobus History/Lore. Eastern white pine seeds are favored by black bears, rabbits, red squirrels and many birds, especially red crossbills. While potentially damaging to the trees, the bark is eaten by mammals such as beavers, snowshoe hares, porcupines, rabbits and mice.
