Where, specifically, is pollen produced?
Stamin (male part of plant). (Pollen is the “male” part)
The female reproductive part of a flower is called:
a. pistil. c. stamen.

Pollination (releases pollen), and then fertilizes other plants
What are the three parts of a seed?
- the embryo
- some stored food
- a protective seed coat
How do flower petals help a flowering plant reproduce?
Petals attract insects and animals that help spread pollination
What type of reproduction does not increase genetic variation?
Asexual (offspring looks same)
Would the genes of two trees that grew from separate root sprouts of the same parent tree be identical?
.
List three commercial crops that are reproduced asexually
Seedless grapes
Seedless bananas
Potatoes
What is the main function of gametes?
They transfer or receive chromosomes. Gametes combine at fertilization to make a zygote, which then grows into a new organism. I
(True or False) The chromosomes of plants usually occur in pairs just as those of animals do?
