Question 3

In seed plants, what does the megaspore develop into?

Accepted Answer

Female gametophyte

Question 4

Which structure in seed plants contains the megasporangium, megaspore, and one or more protective integuments?

Accepted Answer

Ovule

Question 5

What is the main evolutionary advantage of seeds compared to spores?

Accepted Answer

Seeds contain stored food and can remain dormant until conditions are favorable

Question 6

Which of the following statements about gymnosperm and angiosperm ovules is correct?

Accepted Answer

Gymnosperm ovules have one integument, angiosperm ovules usually have two

Question 7

In seed plants, what is the function of the pollen tube?

Accepted Answer

To transport sperm directly to the female gametophyte within the ovule

Question 8

Which of the following best describes heterospory in seed plants?

Accepted Answer

Production of both microspores and megaspores, leading to separate male and female gametophytes

Question 9

Which of the following is NOT a phylum of gymnosperms?

Accepted Answer

Magnoliophyta

Question 10

What is the correct sequence of events in the fertilization process of seed plants?

Accepted Answer

Pollination → pollen tube formation → sperm discharge → fertilization of egg

Question 11

Which of the following is a key adaptation found only in angiosperms and not in gymnosperms?

Accepted Answer

Flowers specialized for sexual reproduction

Question 12

Accepted Answer

They provide food, fuel, construction materials, and medicines

Question 15

Which formula correctly represents the ploidy of the structures in a fertilized ovule of a gymnosperm?

Accepted Answer

$$Embryo: 2n, Food supply: n, Seed coat: 2n$$

Question 16

Which process allows seed plants to reproduce without the need for water for sperm transport?

Accepted Answer

Pollination via pollen grains

Question 17

Which of the following is true about the gametophytes of seed plants?

Accepted Answer

They are reduced, usually microscopic, and dependent on sporophyte tissue for nutrition

Question 18

Which of the following is a correct description of the difference between microspores and megaspores in seed plants?

Accepted Answer

Microspores develop into male gametophytes, megaspores into female gametophytes

Question 19

Which of the following is a real-world example of the importance of angiosperms to human society?

Accepted Answer

The production of wheat, rice, and corn as staple crops

Question 20

Which of the following statements about pollination is correct?

Accepted Answer
