Leaves are composed of vascular tissue that brings water in so that ground tissue can conduct photosynthesis. Based on this information, what level of organization describes leaves?

• Tissue

• Organ

• Organ system

Trees that grow in a forest tend to grow very tall, with few branches. The same species of tree grown in an open area tends to grow shorter and wider, with many branches. The stimulus responsible for these different growth patterns is the amount of -

• wind striking the tree

• light reaching the tree

• nutrients in the soil

• water in the ground

Students observed a plant left by a window over several days. The plant was watered daily. After three days, the plant began to grow towards the window as shown in the picture.

Which of the following best explains the student’s observations?

• Heat from the Sun caused the plant to grow towards the window.

• The plant is leaning towards the window to get fresh air.

• The plant is responding to the stimulus of sunlight.

• The plant is responding to water in the air and growing towards it.
