• transports food down from the leaves to the rest of the plant
• transports water and minerals down from the roots to the rest of the plant
• transports food up from the leaves to the rest of the plant

A bacterial disease starts to make the leaves of a plant began to wilt and fall off. If the disease is not addressed and cured soon the leaves of the plant will begin to die. Which of these functions would be most immediately affected by the loss?

• Disease resistance

• Seed dispersal

• Sunlight absorption

• Water absorption

Venus flytraps uses sweet nectar to lure insects into specialized leaves that captures prey which are triggered to close when the insect rubs against sensitive hairs. The sensitive hairs are only triggered by living things. Venus flytraps digest the insect in a matter of a few days. Based on this information what function do the specialized leaves perform?

• Provide water to the plant and perform photosynthesis

• Respond to stimuli and anchor the plant

• Provide nutrients to the plant and respond to stimuli

• Release pollen to insects and perform photosynthesis

A student designs an experiment to demonstrate the presence of openings in the walls of xylem cells in plants. He takes a long-stemmed, white chrysanthemeum (flowering plant) and carefully cuts the stalk halfway up. He places each half of the stalk in a glass cylinder filled with water. Red dye is added to one cylinder; blue dye is added to the other. What observations would you expect to make over the next few days?

• The flower remains white.
• The flower turns blue, then changes to red.
• The flower turns red, then changes to blue.
• Initially part of the flower will be blue and part will be red, but eventually both colors will appear in all parts of the flower.

To determine if the direction of root growth is influenced by the orientation of seeds when they are planted, an investigation was set up as shown in diagram A below. The container was placed in the dark for one week. The results are shown in diagram B. Which factor caused the emerging roots to grow downward?

• Lack of light, which prevented photosynthesis

• Loss of water from the seeds during the week

• The influence of temperature on root growth

• The influence of gravity on hormone distribution in each root

The plant shown below is growing in a glass beaker with access to water, nutrients, and light. What explanation best accounts for the directional change in growth observed in the plant shown?

• The plant was only watered on the left side of the beaker.

• The plant was initially grown in the dark, then was placed in the sunlight.

• The plant was initially grown on its side in a tray of water, then moved upright into a beaker.

• Sunlight is only accessible from the left side of the beaker.
