Which part of the plant usually grows under the soil?

• Stem

• Leaves

• Roots

• Flowers

What is the main function of root hairs?

• To make food for the plant

• To suck up water and nutrients

• To hold the plant upright

• To protect the plant from animals

Which process do leaves use to make food for the plant?

• Respiration

• Germination

• Photosynthesis

• Transpiration

The stem helps the plant survive by:

• Storing food for the plant.

• Holding the plant upright and carrying water, nutrients, and food.

• Absorbing water from the soil.

• Making seeds for the plant.

Why are flowers, fruits, and seeds important to plants?

• They help the plant absorb sunlight.

• They are the reproductive structures that help the plant make more plants.

• They store water for the plant.

• They protect the plant from wind.

• Food and sugar

• Oxygen and carbon dioxide

Which environmental factor helps plants grow stronger leaves and stems? (DoK Level 1)

• Wind

• Light

• Rain

• Soil

Why are roots important for a plant? (DoK Level 2)

• They help the plant make food

• They help the plant drink water and stand up

If a plant does not get enough sunlight, what is most likely to happen? (DoK Level 2)

• It will grow faster

• It will become pale and weak

• It will produce more flowers

• It will need less water

Imagine a plant is not growing well. Using what you know about environmental factors, what could you check to help the plant grow better? (DoK Level 3)

• If the plant has enough sunlight, the right temperature, and nutrients
