Trees Lesson 1-5 Quiz: Photosynthesis and Osmosis 2021-22

What is diffusion?

• when molecules move into a cell

• when molecules move from a high concentration to a low concentration

• when molecules have no movement

• when molecules move everywhere

Osmosis is the movement of _____ across a membrane.

• food
• energy
• oxygen
• water

During osmosis

• water moves from high to low concentration
• large molecules move across a cell membrane

• water moves when energy is used
• proteins are built

Cells that are hypertonic, but are inside a hypotonic solution will

• Shrink/Dehydrate
• Expand

Which statement about photosynthesis is correct?

• Plants get the energy they need for photosynthesis from water.

• Plants do not require energy to perform photosynthesis.

What are the products of photosynthesis?

Here is the photosynthesis equation for reference:

CO₂ + H₂O --> C₆H₁₂O₆ + O₂
