SOL 4.2 Plant & Animal Structures

Animals help seeds travel by _________.

• eating seeds and dropping waste later on

• hiding seeds in the winter and not coming back for them

• catching seeds on their fur and carrying them to different places

• all of the above

Answer explanation

Animals help seeds travel in various ways: by eating seeds and later dropping them, hiding them and forgetting, or catching them on their fur. Therefore, the correct answer is 'all of the above'.

A healthy yellow-flowered tulip is shown.

Which of the following would occur first as a result of a drought (not enough rain)?

• The tulip's stem would grow longer.

• The tulip's flowers would turn blue.

• The tulip's leaves would wilt.

Answer explanation

In a drought, the first visible effect on a tulip is wilting of the leaves due to water loss. This response helps the plant conserve moisture, making 'the tulip's leaves would wilt' the correct choice.

Lauren is working on a science experiment involving plant chlorophyll. She has 10 plants from which she can get chlorophyll samples, but she is unsure where to find the most chlorophyll. In which of the following plant parts would she find the greatest amount of chlorophyll?

• in the roots

• on the stem

• in the leaves

• on a flower

Answer explanation

Chlorophyll is primarily found in the leaves of plants, where photosynthesis occurs. The leaves contain chloroplasts, which are rich in chlorophyll, making them the part of the plant with the greatest amount of this pigment.

What is necessary for a plant to conduct photosynthesis?

• oxygen and water

• carbon dioxide and water

• oxygen, sugar, and soil

• carbon dioxide, water, and sunlight

Answer explanation

For photosynthesis, plants need carbon dioxide, water, and sunlight. Carbon dioxide is absorbed from the air, water is taken up from the soil, and sunlight provides the energy to convert these into glucose and oxygen.

How do plants use sunlight?

• to dry out their roots

• to make their own food

• to turn their leaves green

• to make carbon dioxide

Answer explanation

Plants use sunlight to make their own food through a process called photosynthesis. They convert sunlight, carbon dioxide, and water into glucose and oxygen, which is essential for their growth and energy.

The plant parts necessary for photosynthesis are located in -

• 1

• 2

• 3

• 4

Answer explanation

The plant parts necessary for photosynthesis, primarily chloroplasts found in leaves, are crucial for converting sunlight into energy. Therefore, the correct answer is 1.

What plant parts help carry nutrients to the remainder of the plant?

• 1 and 2

• 2 and 3

• 1 and 3

• 4 and 5

Answer explanation

The correct answer is 4 and 5, as these parts refer to the xylem and phloem, which are responsible for transporting water and nutrients throughout the plant.

Which part of the plant is being described?

• leaves

• roots

• stem

• flower

Answer explanation

The stem is the part of the plant that supports leaves, flowers, and fruits. It transports nutrients and water between the roots and the rest of the plant, making it essential for growth and stability.

Plants need what to do photosynthesis?

• Food absorbed from ground

• Sun's energy

• Food broken down

• Minerals from the soil

Answer explanation

Plants need the Sun's energy to perform photosynthesis, which allows them to convert light into chemical energy. The other options do not provide the necessary energy for this process.

Which plant part absorbs water and nutrients?

• Leaf

• Stem

• Roots

• Flower

Answer explanation

The roots are the part of the plant that absorb water and nutrients from the soil. They anchor the plant and play a crucial role in its growth and health, making them essential for nutrient uptake.
