What does Pollen and seeds evolved in response to?
Pollen and seeds evolved in response to the need for more efficient reproduction in plants. Pollen enables plants to transfer male gametes to female reproductive structures without the need for water, thus increasing the chances of successful fertilization. Seeds evolved to protect and nourish the developing plant embryo, ensuring its survival and dispersal to new locations.
What does pollen join with to make seeds?
pollen joins an ovule to make seeds
Do gametophytes produces seeds or pollen?
Gametophytes produce pollen, which is the male gametophyte. Seeds are produced by the fertilization of the female gametophyte by pollen.
Seeds have evolved to obtain what gamete exchange?
Seeds have evolved to facilitate reproduction and dispersal of plant species. They are the result of the fusion of male and female gametes (sperm and egg) and contain an embryo and nutrient reserves enclosed in a protective seed coat. This allows seeds to be dispersed, germinate, and develop into new plants in diverse environments.
What do flowers produce?
A flower produce pollen sacs which has pollen grains in it
What is inside a pollen cell?
seeds
What the fertilization?
the seeds and embryos and pollen
What structure have they evolved to obtain gamete exchange?
Pollen
Why must a flower be pollinated to make seeds?
The ovary in the flower must be fertilised by pollen from the stamen and then seeds can form.
How are pollen cones and seed cones different?
Conifer trees have two different kinds of cones. The pollen cones house the male reproductive cells. They produce pollen which is later transferred to the female cone to fertilize the seeds. The seed cone houses the female reproductive cells, which when pollinated become seeds.
Can pollen be described as seeds?
No, pollen cannot be described as seeds. Pollen is a fine powder produced by flowering plants that contains male gametes, which are necessary for fertilization. Seeds, on the other hand, are the result of fertilization and contain an embryo along with stored nutrients, allowing for the development of a new plant. While both pollen and seeds are crucial for plant reproduction, they serve different roles in the life cycle of plants.
Do male palm trees produce seed?
No, they are male trees and only produce pollen
