What do plants primarily produce for themselves through photosynthesis?

• Glucose

• Oxygen

• Water

• Carbon dioxide

What is the relationship between photosynthesis and cellular respiration?

In which organelle can chlorophyll be found?

How does chlorophyll interact with different wavelengths of light?

• It absorbs green light and reflects red and blue light.

• It absorbs all wavelengths of light equally.

• It absorbs red and blue light and reflects green light.

• It reflects all wavelengths of light, making plants appear green.

Where do the light-dependent reactions of photosynthesis occur within the chloroplast?

• Stroma

• Cytoplasm

• Nucleus

• Thylakoids

Plants only do photosynthesis, while animals only do cellular respiration.

• True

• False - plants perform both photosynthesis and cellular respiration

• False - animals perform photosynthesis and not cellular respiration

• False - animals perform both photosynthesis and cellular respiration

How do cacti adapt to hot, dry environments to perform photosynthesis efficiently?

• They open their stomata at night to collect carbon dioxide and close them during the day to conserve water.

• They open their stomata during the day to maximize carbon dioxide intake and water release.

• They have no stomata, relying on direct absorption of carbon dioxide through their waxy coating.

• They perform photosynthesis only at night, using stored energy from the day.

Explain how the opening and closing of the stomates helps the plant maintain homeostasis.
