Unit 4c Review

Match the following functions to the corresponding organelle.

• Lysosomes

• Creates proteins for a cell

• Chloroplast

• Creates glucose for a plant cell

• Mitochondria

• Protects a cell, controls what enters and exits it

• Ribosomes

• Breaks down glucose for a cell, creates energy for the cell

• Cell membrane

• Digests and breaks down things for a cell

Does photosynthesis store carbon as biomass or release it into the environment?

• Stores carbon

• Releases carbon

What input of energy is required for plants to go through photosynthesis? It is usually placed above the arrow in the chemical equation.

• ATP

• glucose

• Sunlight

A student places four small snails in a test tube containing bromothymol blue. The solution will change color from blue to yellow if the CO2 level increases. The student seals the test tube and notes that the solution is blue. After a few hours, the student observes that the solution is yellow. What process did the snails go through?

• Cellular respiration

• Chemical Digestion

• Photosynthesis

Which organelle would be found in plant cells but not other eukaryotic cells?

• Chloroplast

• Cell membrane

• Mitochondria

• Nucleus

• Vacuole

• Mitochondria

• Ribosome

• Nucleus

Does cellular respiration store carbon as biomass or release it into the environment?

• Stores carbon

• Releases carbon
