Investigating Plant Systems and Homeostasis

Describe the role of vacuoles in plant cells.

• They produce energy for the cell.

• They store nutrients, waste products, and help maintain turgor pressure.

• They control cell division.

• They synthesize proteins.

Explain how cells maintain homeostasis by getting rid of waste.

• Cells use chloroplasts to convert waste into energy.

• Cells use the cell membrane to expel waste products.

• Cells store waste in the nucleus.

• Cells use mitochondria to break down waste.

How do plant cells differ from animal cells in terms of structure?

• Plant cells have a cell wall and chloroplasts, while animal cells do not.

• Animal cells have a cell wall and chloroplasts, while plant cells do not.

• Both plant and animal cells have a cell wall and chloroplasts.

How do cells of all organisms undergo similar processes to maintain homeostasis?

• By using the same organelles for different functions.

• By extracting energy from food, getting rid of waste, and reproducing.

• By storing energy in the nucleus and using it when needed.

• By converting waste into energy.

11. The diffusion of water through a selectivelypermeable membrane is called:

• Active Transport

• Osmosis

• Endocytosis

• Exocvtosis

• Equilibrium

• Water will diffuse into the plant cell

• Water will diffuse out of the plant cell

• Water will not diffuse

• Against the concentration gradient
