Biology Q3 Exam

Where does photosynthesis occur?

• mitochondria

• chloroplast

• animal cells

• ribosomes

What is the name of the pigment molecule that absorbs light energy and makes plants green?

• chloroplast

• glucose

• mitochondria

• chlorophyll

What gas is released by plants during photosynthesis?

• sulfur
• carbon dioxide
• oxygen
• hydrogen

What are the products of photosynthesis?

• water and carbon dioxide
• oxygen and glucose
• oxygen and carbon dioxide
• oxygen and water

What is the source of energy for photosynthesis?

• carbohydrates-chemical
• sunlight-radiant
• heat-thermal
• television-electrical

Chlorophyll is green because

• it absorbs green wavelengths of light
• it absorbs blue and yellow wavelengths of light
• it reflects green wavelengths of light
• it is an optical illusion caused by the transmission of light

Which choice correctly shows the gases that enter and exit plants during photosynthesis?

• Enter: Oxygen
  Exit: Carbon dioxide
• Enter: Water vapor
  Exit: Glucose
• Enter: Carbon dioxide
  Exit: Oxygen
• Enter: Light
  Exit: Water vapor

What is the name of the 1st step of cellular respiration?

• Glycolysis
• Kreb's Cycle
• ETC
• Anaerobic respiration

Where does glycolysis take place?

• Cytoplasm
• Stroma
• Thylakoid
• Mitochondria

This process releases chemical energy from sugars and other carbon-based molecules to make ATP when oxygen is present.

• photosynthesis
• light-independent reaction
• cellular respiration
• light-dependent reaction
