• glucose

• carbon dioxide

• sunlight

Why would giving a plant an energy drink not affect the rate of photosynthesis?

• Plants require water, sunlight, and CO2. Giving them something they don't need doesn't affect photosynthesis.

• Energy drinks increase chlorophyll production in plants.
• Plants can absorb caffeine to enhance photosynthesis.
• Energy drinks provide essential nutrients for photosynthesis.

What does the experiment shown demonstrate about plants and photosynthesis?

• Plants absorb carbon dioxide during photosynthesis.
• Plants use sunlight to grow roots only.
• Plants produce glucose without sunlight.
• Plants produce oxygen during photosynthesis.

Plants contain pores along the surface of their leaves. These stomata are used to excrete waste. What does it mean for a plant to excrete substances?

• For a plant to excrete substances means to store water in its roots.
• For a plant to excrete substances means to eliminate waste products from its body.
• For a plant to excrete substances means to photosynthesize sunlight into energy.
• For a plant to excrete substances means to absorb nutrients from the soil.
