Cell Processes

During the Egg Lab, what process occurred when the water and vinegar passed in and out of the egg?

Which describes process of osmosis?

• liquids only

• does not need a semipermeable membrane

• stomata opening up for carbon dioxide to enter the leaf

• solvent and solute particles move freely

Which best describes the process of diffusion?

• allows water to enter the roots of a plant

• does not need a semipermeable membrane

• liquids only

• solids only

What do osmosis and diffusion have in common? (Check boxes)

• movement to find equilibrium

• passive transport (no energy required)

• solids movement

• move from high to low concentration

What process occurs when water enters the roots of a plant so that photosynthesis can occur?

What are the reactants of photosynthesis?

• glucose (C₆H₁₂O₆)

• oxygen (O₂)

• carbon dioxide (CO₂)

• water (H₂O)

• energy (sunlight)

What are the products of photosynthesis?

• glucose (C₆H₁₂O₆)

• oxygen (O₂)

• carbon dioxide (CO₂)

• water (H₂O)

• energy (sunlight)

Why do humans and other heterotrophs need photosynthesis?

The first step in photosynthesis is...

• water enters the leaves and goes to the roots

• carbon dioxide exits the leaves and chloroplasts soak up sunlight

• carbon dioxide and glucose enter the body

• water enters through the roots, carbon dioxide enters through the stomata, and chloroplasts soak up sunlight

What organelle captures sunlight to produce energy for photosynthesis?

• chloroplast

• chlorophyll

• mitochondria

• nucleus
