What organelle works with the plasma membrane to store water brought in so it can be used at a later time, especially in plants?

• vacuole
• cytoplasm
• chloroplast
• mitochondria

Which best explains the relationship between chloroplasts and mitochondria?

• Chlorplasts absorb light energy from the sun, which is converted to glucose by the mitochondria. 
• Chloroplasts produce carbon dioxide and water, which are used by the mitochondria to produce energy. 
• Chloroplasts store energy in the chemical bonds of glucose, which is used by the mitochondria to produce ATP.
• Chloroplasts release light energy stored in the glucose in the form of ATP, which is absorbed by mitochondria.
