Question 17 What is the function of a colorful fragrant flower on a flowering plant? Collect nutrients from the fecal droppings of visiting insects, which will help form the endosperm that will nourish the embryo when the seed germinates. To entice humans into domesticating the species, propagating it in our gardens, and tending to its every need by delivering water, fertilizer, and many more services. To attract animal pollinators so that sperm can be carried to eggs efficiently. To shield the delicate egg (and after fertilization, embryo) from wind, UV rays, and drying out Question 18 Which type of land plant has sperm capable of creating a pollen tube that allows the sperm to burrow it's way to egg? mosses and ferns gymnosperms and angiosperms

Plant Structure and Function Across 3. Fertilised ovum before it starts to divide into more cells. 5. Protects the flower bud before it opens. 6. The hollow, lower end of the carpel containing the ovules. 7. A long tube growing from a pollen grain through the style to the ovule 9. The coloured part of a flower that attract insects. 10. The female part of a flower, at the top of the carpel, that catches the pollen during pollination. 11. The male part of a flower that makes pollen Down 1. The male gametes of a flower. 2. Transfer of pollen from the stamen (the male part) of a flower to the stigma (the female part) of a flower. 4. The reproductive part of angiosperms (plants). 8.

Which of the following correctly describes the function of a seed? Contains the plant embryo and a tissue such as endosperm to provide nutrition for early plant growth. Grows from the ovary of a flowering plant and surrounds the seed. Provides protection and/or attracts animals to aid in seed dispersal. The reproductive structure of the angiosperms. The reproductive structure of the gymnosperms. Carries the microgametophyte and sperm cells during sexual reproduction in angiosperms.
Madhur L.
In angiosperms, each pollen grain produces two sperm. What do these sperm do? a. Each one fertilizes a separate egg cell. b. One fertilizes an egg, and the other is kept in reserve. c. Both fertilize a single egg cell. d. One fertilizes an egg, and the other fertilizes a cell that develops into stored food.
