Where do gymnosperm seeds develop?
Gymnosperm seeds develop on the surface of specialized structures called cones. These cones are found on the branches of gymnosperm trees and shrubs, and they protect the seeds until they are mature enough to be dispersed.
Where is pollin made?
Pollen is made by male parts of flowering plants, called anthers, which produce pollen grains. These grains are then transferred to the female parts of a flower for fertilization to occur.
How is pollen transferred from the male to the female cone?
By various means, depending on the species. In some, bees and other insects go for the honey and in doing so get pollen on them which they then transfer to another flower when they visit that. In others, wind blows the pollen from the anthers (the male part) to the stigma (the female part). In others, the anthers bend over and touch the stigma. All sorts of methods.
What is the fertilizing powder produced by plants called?
The fertilizing powder produced by plants is called pollen. Pollen contains the male reproductive cells of a plant and is transferred to the female reproductive organs of the same or a different plant to enable fertilization.
What is one entire male gametophyte of a gymnosperm?
The male gametophyte of a gymnosperm is a pollen grain, which consists of two cells: a generative cell that will divide to form two sperm cells, and a tube cell that aids in the pollen tube formation.
What is the reproductive structure of gymnosperm called?
The reproductive structure of a gymnosperm is the cone. The cone produces pollen or sperm cells that will later on fertilize a female plants eggs or anthers
Which is the reproductive event in conifers where pollen grains from male cones are transferred to female cones called?
pollination

What are gymnosperm eggs fertilized in?
Gymnosperm eggs are typically fertilized through the process of pollination. Pollen grains are carried by wind or insects to the female ovule where fertilization occurs, resulting in the formation of a seed.

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.
What can anthers produce?
The anther produces pollen grains which would be transferred to other plant's stigma which will receive the pollen grains when an insect fly pass it then the pollen grains will be stuck on its wings.
What is one entire male gametophyte of a gymnosperm?
The male gametophyte of a gymnosperm is a pollen grain, which consists of two cells: a generative cell that will divide to form two sperm cells, and a tube cell that aids in the pollen tube formation.
What does the male cone of a gymnosperm produce?
Male cannabis plants grow pollen sacks with seeds, while the female grows buds.
What is a flower's sperm?
A flower's sperm is contained within the pollen grains. These pollen grains are produced in the male reproductive organs of the flower, called the stamens. When the pollen grains are transferred to the female reproductive organs of another flower, they can fertilize the ovules and lead to seed development.
