In conifers such as pines sperm contained in pollen grains are primarily transferred to an egg by what?
In conifers, such as pines, sperm contained in pollen grains are primarily transferred to an egg by wind pollination. This process involves the dispersion of pollen from male cones to female cones through the air. Once the pollen reaches the female cone, it fertilizes the egg to form a seed.
The reproductive organs of gymnosperms are found in what?
The reproductive organs of gymnosperms are found in cones, which can be either male (pollen cones) or female (seed cones). The pollen cones produce pollen, while the seed cones contain the ovules where the seeds develop.
Are pine cones seeds?
Yes, pine cones contain seeds that are released when the cones open. Each scale on a pine cone holds two seeds, which are dispersed once the cones mature and open.
What are cone-bearing plants such as pines and firs called?
Cone-bearing plants like pines and firs are called gymnosperms. They are characterized by bearing seeds in cones rather than enclosed in fruits like angiosperms. Gymnosperms include other plants like spruces, cedars, and cycads.
What types of plants have reproductive structures on cones?

What trees do cones come from?

Is bristle cone pine a gymnosperm or angiosperm?
Bristlecone pine is a gymnosperm. Gymnosperms are seed-producing plants that do not have flowers, and the seeds are usually exposed on the surface of cones. Bristlecone pines produce cones to disperse their seeds.
What food you should eat to enlarge your pines?

What is true about seed cones?
Seed cones are seeds from which a tree or bush will grow.
Do cypress trees get pine cones?
Cypress trees do not produce pine cones; instead, they produce small, round seed cones. These cones typically contain seeds that are dispersed by wind or water. Cypress trees belong to the family Cupressaceae, which is distinct from pines, and their reproductive structures differ from those of true pine trees.
What is difference between seed cones and pollen cones?
Pollen cones are the male pollen-producing cones, and seed cones are the female seed-producing cones in conifer trees.Seed cones are gymnosperms, which means the seeds are not enclosed within an ovary (in Greek, gymno is naked).
What tree is a coniferous tree?
a coniferous tree is a tree in which produces cones. the seed is sometimes called a gymnosperm.
Is there pollen cones and seed cones on the same trees?
Yes, in case of Pinus pollen producing cones (male cones) and seed producing cones (female cones) are present on the same plant. Such plants are called monoecious.
Austrian pine trees do not have pine cones how do they seed?
The Austrian pine Pinus nigra carries cones that bear the seeds, therefore, no cones, no seed.
