Question 1

Which of the following is a primary advantage of sexual reproduction in flowering plants compared to asexual reproduction?

Accepted Answer

It increases genetic diversity, enhancing adaptability to changing environments.

Question 2

During the formation of the male gametophyte in angiosperms, what is the sequence of cell division that leads to the mature pollen grain?

Accepted Answer

Meiosis followed by mitosis

Question 3

Which structure in the flower is responsible for producing pollen grains?

Accepted Answer

Anther

Question 4

Double fertilization in angiosperms results in the formation of which two structures?

Accepted Answer

Zygote and endosperm

Question 5

Which equation best represents the ploidy of the endosperm formed during double fertilization?

Accepted Answer

$$n + 2n = 3n$$

Question 6

What is the main function of the pollen tube during fertilization in flowering plants?

Accepted Answer

To transport sperm cells to the egg cell

Question 7

Which of the following best describes the difference between spores and seeds?

Accepted Answer

Spores are haploid and seeds are multigenerational and multicellular.

Question 8

In the process of germination, which structure emerges first from the seed?

Accepted Answer

Radicle

Question 9

Which of the following is a key survival advantage of seed dispersal by animals?

Accepted Answer

Seeds escape deteriorating environments and avoid competition.

Question 10

Which part of the flower develops into the fruit after fertilization?

Accepted Answer

Ovary

Question 11

A plant species relies on bumble bees for pollination. If the bees evolve to become larger and more colorful, what evolutionary process is most likely occurring?

Accepted Answer

Coevolution

Question 12

Which of the following statements about gymnosperms is correct?

Accepted Answer

Gymnosperms rely primarily on wind pollination.

Question 13

During the formation of the female gametophyte, how many megaspores survive after meiosis?

Accepted Answer

One

Question 14

Which of the following best describes the role of cotyledons during seed germination?

Accepted Answer

They provide nutrients to the heterotrophic seedling.

Question 15

Which process allows pollen grains to colonize new dry environments without the need for water?

Accepted Answer

Protective tough outer coat of pollen grains

Question 16

Which sequence correctly describes the events leading to the formation of sperm cells in the pollen tube?

Accepted Answer

Meiosis in microsporangium → mitosis in microspore → generative cell divides to form two sperm

Question 17

Which of the following is NOT a function of fruit in angiosperms?

Accepted Answer

Providing nutrients to the embryo

Question 18

Which of the following best explains why asexual reproduction is considered efficient in plants?

Accepted Answer

It allows rapid propagation without the need for pollinators.

Question 19

During germination, which physiological process is triggered by water uptake?

Accepted Answer

Oxygen consumption and protein synthesis

Question 20

Which equation represents the number of chromosomes in a haploid spore compared to a diploid seed?

Accepted Answer

$$n$$
