Question

select all the true statements. in an animal cell, vacuoles store waste, and lysosomes break down waste. in plant cells, vacuoles store sugar, and mitochondria break down the sugar to release energy. in an animal cell, vacuoles store sugar, and mitochondria break down the sugar to release energy. in an animal cell, the endoplasmic reticulum helps ribosomes make proteins, and the golgi sends proteins to different parts of the cell.

Explanation:

• First statement: In animal cells, vacuoles can store waste and lysosomes contain digestive enzymes to break down waste - this is a correct cell - organelle function relationship.
• Second statement: In plant cells, vacuoles can store substances like sugar. Mitochondria are the power - houses of the cell that break down sugar (through cellular respiration) to release energy (in the form of ATP) - this is correct.
• Third statement: In animal cells, vacuoles do not typically store sugar. Animal cells get sugar from the external environment and store it in forms like glycogen (not in vacuoles). So this statement is false.
• Fourth statement: The endoplasmic reticulum (especially the rough endoplasmic reticulum) has ribosomes attached to it and helps in protein synthesis. The Golgi apparatus modifies, sorts, and sends proteins to different parts of the cell or for secretion - this is a correct description of their functions.

Answer:

• In an animal cell, vacuoles store waste, and lysosomes break down waste.
• In plant cells, vacuoles store sugar, and mitochondria break down the sugar to release energy.
• In an animal cell, the endoplasmic reticulum helps ribosomes make proteins, and the Golgi sends proteins to different parts of the cell.
