Question

part a a plant cell is placed in a solution with a lower concentration of solutes than inside the cell. which organelle helps maintain homeostasis by managing the excess water that enters the cell? a lysosome b mitochondrion c vacuole d ribosome part b which statement best supports your answer to part a? a this part of the cell is the site of cellular respiration. b this part of the cell maintains osmotic balance. c this part of the cell helps with protein synthesis. d this organelle maintains waste and digestion within the cell

Explanation:

For Part A: When a plant cell is in a hypotonic solution (lower solute concentration outside), water enters the cell. The large central vacuole in plant cells stores and regulates this excess water to maintain homeostasis. Lysosomes handle waste digestion, mitochondria produce energy, and ribosomes make proteins, so they do not manage excess water.
For Part B: The vacuole's key role in this context is maintaining osmotic balance by controlling water levels, which directly supports the answer to Part A. Option A refers to mitochondria, option C refers to ribosomes, and option D refers to lysosomes.

Answer:

Part A: C. Vacuole
Part B: B. This part of the cell maintains osmotic balance.
