Answer 30

Gymnosperms and angiosperms

Question 31

Why do seedless plants require water for fertilization?

Answer 31

Sperm are flagellated and can only swim in water

Question 32

What process occurs in seed plants that transports male gametophytes to the female gametophytes by wind, water, or animal without requiring water?

Answer 32

Pollination

Which part of the conifer life cycle is the male and female gametophytes?

Answer 34

Male- pollen cones that contain pollen grains Female- seed cones that contain ovules

Question 35

Where does fertilization occur in gymnosperms?

Answer 35

Ovary

Question 36

What structure becomes the seed in gymnosperms?

Answer 36

Ovule

Question 37

How is pollination accomplished by flowering plants?

Answer 37

Wind, water, and animal carriers

Question 38

Which part of the flowering plant life cycle is the male and female gametophyes?

Answer 38

Male- anthers contain pollen grains Female- ovary contains ovules

Question 39

When a pollen tube delivers sperm to the embryo sac, double fertilization occurs. What cells do the sperm fuse with, and what do they form?

Answer 39

One sperm fuses with an egg to form a zygote and a second sperm fuses with the nuclei of the central cell of the female gametophyte to form the endosperm

Question 40

What structure becomes the seed and what becomes the fruit?

Answer 40

Ovules become seeds Ovaries become fruit

Question 41

Are the following present in each type of seeded vascular plant?

Answer 41

Question 42

What structure in gymnosperms and angiosperms delivers sperm from pollen sacs to the vicinity of the egg? Does this require water?
