Correct Answer: B) The transfer of pollen from one plant to another plant of the same species

Which of the following is an advantage of cross-pollination?

A) Reduces genetic diversity B) Ensures self-fertilization C) Promotes stronger and more adaptable offspring D) Prevents pollination altogether

Correct Answer: C) Promotes stronger and more adaptable offspring

Which mechanism prevents self-pollination in monoecious plants?

A) Cleistogamy B) Protandry and protogyny C) Self-fertility D) Lack of reproductive organs

Correct Answer: B) Protandry and protogyny

In cross-pollination, what happens when the pollen grain reaches the stigma?

A) It immediately fertilizes the ovule B) It forms a pollen tube for fertilization C) It dries up and falls off D) It transforms into a seed

Correct Answer: B) It forms a pollen tube for fertilization

Which of the following is NOT a common agent of pollination?

A) Wind B) Water C) Insects D) Soil

Which of the following flowers is most likely to be pollinated by insects?

A) A flower with small, dull-colored petals B) A flower with bright petals and a strong scent C) A flower with large feathery stigmas D) A flower with light, smooth pollen grains

Correct Answer: B) A flower with bright petals and a strong scent

What adaptation is common in wind-pollinated flowers?

A) Large, heavy pollen grains B) Sticky stigmas C) Large amounts of small, light pollen D) Sweet nectar production

Correct Answer: C) Large amounts of small, light pollen

Which type of pollination occurs in aquatic plants?

A) Anemophily (Wind pollination) B) Hydrophily (Water pollination) C) Entomophily (Insect pollination) D) Ornithophily (Bird pollination)

Correct Answer: B) Hydrophily (Water pollination)

What feature helps insect-pollinated flowers attract pollinators?

A) Large quantities of dry pollen B) Bright colors and scents C) Feathery stigmas D) High pollen production

Correct Answer: B) Bright colors and scents

Why do wind-pollinated flowers lack nectar?

A) They do not need to attract pollinators B) They store nectar in leaves instead C) They rely on water for fertilization D) Nectar prevents pollination

Correct Answer: A) They do not need to attract pollinators

What is a key feature of the stigma in wind-pollinated flowers?

A) Large and sticky B) Small and smooth C) Large and feathery D) Thick and waxy

Correct Answer: C) Large and feathery

Which type of pollination involves animals such as hummingbirds and bats?

A) Anemophily B) Hydrophily C) Zoophily D) Self-pollination

Correct Answer: C) Zoophily

Why do wind-pollinated plants produce large amounts of pollen?

A) To increase the chances of successful pollination B) To attract insects C) To make pollen heavier D) To store nutrients in pollen

Correct Answer: A) To increase the chances of successful pollination

Which flower structure holds the pollen before pollination?

A) Ovary B) Stigma C) Anther D) Sepal

Correct Answer: C) Anther

What is the role of nectar in pollination?

A) To nourish the developing seed B) To attract pollinators like bees and butterflies C) To transport pollen to the ovary D) To protect the pollen from wind

Correct Answer: B) To attract pollinators like bees and butterflies
