Gail puts a green plant in a closed wooden box. She gives it good soil and plenty of water. What will happen to the plant?

• It will die because it does not get any sunlight.

• It will grow slowly because it also needs plant food.

• It will grow fast because it has good soil and water.

Russ puts three bean plants on a windowsill. He waters the plants daily, measuring in milliliters (mL). The plants are watered the following amounts daily: plant A – 0 mL, plant B – 10 mL, plant C – 25 mL, plant D – 50 mL. Russ measures the height of the plants every week. This table shows his results in centimeters (cm).

Which best describes how much water young bean plants need every day?

• 0 mL

• 10 mL

• 25 mL

• 50 mL

Carlos says that plants do not need soil to grow. Describe an experiment Carlos could do to provide evidence to support his statement.

• Nonliving things provide some of the needs of living things in an ecosystem. Living things can interact with the nonliving things in the ecosystem.

• Nonliving things do not provide any of the needs of living things in an ecosystem. Living things do not interact with living things in the ecosystem.

Lianna does an investigation in which she puts gel all over the leaves of a plant. She notices that the plant dies. Lianna thinks this happens because the stomata are covered. Describe why covering the stomata of the plant would cause it to die.

• Carbon dioxide comes into the plant through the stomata; without carbon dioxide, plants cannot make food/sugar.

• Oxygen and water go out through the stomata; if the plants could not release waste, they would die.

• The stomata brings in nutrients from the soil and distributes them to all parts of the plant; the plant uses these nutrients to make food/sugar

• Oxygen and water is released through the roots; if the plants could not release waste, they would die
