Why do conifers produce more pollen than grains used to fertilize conifer eggs?
Because conifers are pollinated by wind hence to ensure fertilization of each egg clouds of pollen grains are formed.
The agent of pollination for conifers?
The agents of pollination for conifers are usually wind and rarely insects. Conifers produce pollen in large quantities that is lightweight and easily carried by the wind to reach female cones for fertilization. The lack of showy flowers and nectar means that conifers do not rely on insects for pollination as much as other plants do.
Which does fertilization take place in conifers?
In conifers, fertilization takes place in the ovule, which is located within the ovulate cones. After pollination, pollen grains develop into pollen tubes that deliver sperm cells to the ovule, where fertilization occurs. This process typically takes place over a period of time, often spanning several months, as conifer seeds develop within the cones before being released.
What are conufers pollenated by?
Conifers are typically pollinated by wind, as they produce large amounts of lightweight pollen that is carried by the wind to reach female cones for fertilization. Some conifers, like pines and spruces, have separate male and female cones to facilitate this process. Insects are generally not involved in the pollination of conifers.
Where does the fertilization take place in conifers?
In conifers, fertilization occurs within the female cones, specifically in the ovules located in the ovary of the female cone. The male cones produce pollen, which is carried by the wind to the ovules. After pollination, the pollen grain germinates and grows a pollen tube to deliver sperm cells to the ovule, resulting in fertilization. This process typically takes place over a period of time, often spanning several months.

How is fertilization of the egg accomplished?
Fertilization of an egg happens before it is laid.
What happens to the ovary wall after fertilization?
The ovary becomes fruit after fertilization.

Why are conifers not tied to water for reproduction?
Conifers have pollen grains that are dispersed by wind, allowing them to reproduce without relying on water for fertilization. This adaptation allows conifers to thrive in a variety of environments, including those with limited access to water.
What happens durning fertilization?
reproduction
Where fertilization happens?
ampulla of the uterine tube.
What happens if fertilization does not occurs?
If fertilization does not occur, the egg will detach itself and pass through and you will get a normal period.
The megaspore of a conifer will become?
The megaspore of a conifer will become the female gametophyte, which contains the egg cell. This structure is essential for fertilization and seed production in conifers.
