Food Webs, Plant Cells, & Photosynthesis

Which structure gives a plant cell its rigid shape?

• Cell membrane

• Cell wall

• Nucleus

• Chloroplast

What is the function of the chloroplast in a plant cell?

• Storing water

• Controlling the cell’s activities

• Performing photosynthesis

• Breaking down food

Which of the following is found in plant cells but not in animal cells?

• Mitochondria

• Nucleus

• Large vacuole

• Cytoplasm

What is the purpose of the large vacuole in plant cells?

• Store water and nutrients

• Transport materials

• Break down waste

Where is chlorophyll found in a plant cell?

• Mitochondria

• Chloroplast

• Vacuole

• Nucleus

What is the main purpose of photosynthesis?

• To produce oxygen for animals

• To make food (glucose) for the plant

• To break down dead plants

• To absorb water from the soil

What are the reactants (ingredients) of photosynthesis?

• Oxygen and glucose

• Carbon dioxide and water

• Sunlight and oxygen

• Water and glucose

What are the products (results) of photosynthesis?

• Water and carbon dioxide

• Oxygen and glucose

• Sunlight and oxygen

• Chlorophyll and glucose

What is the correct chemical formula for photosynthesis?

• CO₂ + H₂O + sunlight → C₆H₁₂O₆ + O₂

• C₆H₁₂O₆ + O₂ → CO₂ + H₂O

• H₂O + O₂ + sunlight → CO₂ + C₆H₁₂O₆

• CO₂ + O₂ + sunlight → H₂O + C₆H₁₂O₆

What energy source is needed for photosynthesis?

• Wind
