Photosynthesis and Cellular Respiration 6th NC

Why are many plants green?

• plant cells are green so they can hold their shape

• plants absorb green light because it's the most common light

• chlorophyll reflects green (weak, uncommon) light

• rigid cell walls are green and strong

Chloroplasts are...

• A type of pigment used for photosynthesis
• The location inside a plant cell where photosynthesis happens
• The location where cellular respiration happens
• Green beans

What does photosynthesis produce as a byproduct?

• oxygen

• carbon

• glucose

• hydrogen

Plants need ________from the air for photosynthesis

• oxygen
• soil
• carbon dioxide
• sugar

Mitochondria are...

• The location in cells where photosynthesis happens
• Kidney beans
• The location in cells where cellular respiration happens
• A type of pigment used for cellular respiration

What is the purpose of cellular respiration?

• to break down food
• to create energy in the body
• to release energy from food
• there is none; it's a waste of time

ATP is...

• A form of energy the cell can use that is produced by cellular respiration
• A kind of sugar produced in photosynthesis
• A battery

Plants can...

• Only use photosynthesis
• Only use cellular respiration
• Use photosynthesis and cellular respiration

Animals can...

• Only use photosynthesis
• Only use cellular respiration
• Use photosynthesis and cellular respiration

Simple sugar that is an important source of energy

• oxygen

• sunlight

• glucose
