Cell Processes

What is the function of a chloroplast?

• makes proteins for animal cells

• allows materials in and out of the cell

• provides structure and support

• absorbs sunlight for photosynthesis

What organelle is called the "powerhouse" of a cell?

• mitochondria

• nucleus

• cell wall

• cell membrane

When both inside and outside of a cell have the same amount of water it is said that the cell has reached a state of

• Osmosis
• Diffusion
• Equilibrium

Sometimes, energy is required for ____ molecules to go in or out of the cell because they cannot fit into the membrane.

• big
• small
• crunchy
• water

What type of cellular transport uses energy?

• Passive Transport
• Active Transport

Diffusion and Osmosis are examples of...

• Active Transport
• Passive Transport

During diffusion

• substances (things) moves from high to low concentration
• water moves when energy is used
• large or oddly shaped molecules move across a cell membrane
• water moves from high to low concentration

Which of the following is the correct equation for PHOTOSYNTHESIS?

• CO₂ + light + H₂O --> O₂ + Sugar
• CO₂ + sugar + H₂O --> O₂ + light
• _O2 + light + H₂O --> CO₂ + Sugar
• CO₂ + O₂ + H₂O --> Light+ Sugar

Cellular respiration is...

• the process by which cells break down glucose into energy. 
• the process by which cells break light down into energy. 
• the process by which cells communicate with other cells. 

Which of the following is the correct equation for RESPIRATION

• CO₂ + light + H₂O --> O₂ + Sugar
• CO₂ + sugar + H₂O --> O₂ + light
• O₂ + sugar --> CO₂ + H₂O + energy

• CO₂ + H₂O --> energy + Sugar + O₂
