Answer 2

1. Cell wall
2. Large vacuole
3. Chloroplasts

Question 3

What is photosynthesis?

Answer 3

Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to produce oxygen and energy in the form of sugar.

Question 4

Write the equation for photosynthesis.

Answer 4

Carbon Dioxide + Water (+ light energy) → Glucose + Oxygen

Question 5

What are the three main types of cell transport?

Answer 5

1. Diffusion: Movement from high to low concentration
2. Osmosis: Diffusion of water through a partially permeable membrane
3. Active transport: Movement against concentration gradient (requires energy)

Question 6

What is cellular respiration?

Answer 6

Cellular respiration is the process by which cells break down glucose to release energy.

Question 7

Write the equation for cellular respiration.

Answer 7

Glucose + Oxygen → Carbon Dioxide+ Water+ Energy (ATP)

Question 8

What is the function of mitochondria?

Answer 8

Mitochondria are the powerhouse of the cell and produce energy through cellular respiration.
