Which of the following describes the difference between pollination and seed dispersal?

Pollination is the transfer of pollen to the female part of a flower, while seed dispersal is the movement of seeds away from the parent plant.

Pollination involves wind or animals moving seeds, while seed dispersal only occurs through water.

Pollination is the growth of a new plant from a seed, while seed dispersal is the process of bees collecting nectar.

Pollination is the process of a plant producing seeds, while seed dispersal is the fertilization of the egg cell.

Which of the following characteristics is most commonly found in a flower that is wind-pollinated rather than insect-pollinated?

Feathery stigmas and loosely attached anthers that hang outside the flower.

Sticky pollen grains that are designed to hook onto animal fur.

Brightly colored petals and a strong, sweet scent.

Large quantities of sugary nectar produced at the base of the petals.

Which of the following is an example of 'explosive' seed dispersal?

A pea pod drying out and snapping open to flick seeds away.

A cherry being eaten by a bird and the seed being dropped later in droppings.

A dandelion seed being carried over a long distance by a breeze.

A burdock seed sticking to the fur of a passing dog.

Which of the following describes a key adaptation of seeds that are dispersed by the wind, such as those from a sycamore tree?

They have wing-like structures or hairs to increase air resistance and stay airborne longer.

They are surrounded by a fleshy, sweet fruit to attract birds.

They are heavy and smooth to ensure they fall straight to the ground.

They have a waterproof outer shell that allows them to float on rivers.

In the process of plant reproduction, what is the primary role of the stigma?

To provide a sticky surface to capture pollen grains during pollination.

To protect the flower bud before it opens during the growth stage.

To produce ovules which will eventually become seeds after fertilization.

To produce nectar that attracts insects and birds to the flower.

Which of the following describes the process that occurs immediately after a pollen grain successfully lands on a compatible stigma?

A pollen tube grows down through the style to reach the ovary.

The seed immediately drops from the plant to the soil.

The petals turn into leaves to begin photosynthesis.

The anther explodes to release more seeds into the air.

Which of the following describes the process of fertilization in flowering plants, and how does it differ from pollination?

Fertilization occurs when the male nucleus from the pollen fuses with the female egg cell in the ovule, whereas pollination is just the transfer of pollen to the stigma.

Fertilization is when insects visit a flower for nectar, whereas pollination is the growth of the pollen tube.

Fertilization is the process of seeds being spread by animals, while pollination is the growth of the flower bud.

Fertilization is the release of pollen from the anthers, whereas pollination is the formation of a fruit around a seed.

Why is it important for a plant to disperse its seeds far away from the parent plant?

To reduce competition for light, water, and minerals between the parent plant and its offspring.

To make sure the seeds have enough shade to prevent them from drying out.

To allow the parent plant to provide nutrients to the growing seedlings.

To ensure that the seeds are close enough to the parent for protection.
