A researcher plants two daisy plants (P and Q) that are 5 cm in height in similar pots. The researcher places each plant in two different cardboard boxes of the same size, one with a light bulb and the other without a light. The image shows the setup of the experiment. After a week, the researcher records the change in height for each plant in a table. What can be inferred about daisy plants from the data?

• Daisy plants do not require light for growth.

• Daisy plants grow well in cardboard boxes.

• Light from the bulb did not help daisy plant Q grow.

• Light is needed in order for daisy plants to perform photosynthesis.

A student has two rose plants of the same height with the same pot size, soil, and water. The student places one rose plant in sunlight. The table shows the data collected after a week. The student claims plants need energy from the environment to grow. Do the results of the experiment support the claim made by the student?

• Yes. Plant 1 grew taller, and its leaves were green.

• Yes. Plant 2 grew taller, and its leaves were green.

• No. Plant 1 did not grow taller, and its leaves were yellow.

• No. Plant 2 did not grow taller, and its leaves were yellow.

The rainforest is divided into four basic layers. The amount of water, nutrients, and sunlight a plant receives is related to its layer. Which pair of statements is true about the amount of sunlight received by the leaves of plants in different rainforest layers?

• Plants in the emergent layer receive the most sunlight. These plants are more likely to be shorter than canopy layer plants, which receive the least sunlight.

• Plants in the emergent layer receive the most sunlight. These plants are more likely to be taller than forest floor layer plants, which receive the least sunlight.

• Plants in the canopy layer receive the most sunlight. These plants are more likely to be taller than understory layer plants, which receive the least sunlight.

• Plants in the forest floor layer receive the most sunlight. These plants are more likely to be shorter than understory layer plants, which receive the least sunlight.
