Which organelle in eukaryotic cells is primarily responsible for storing food and water?
A
Vacuole
B
Ribosome
C
Mitochondrion
D
Golgi apparatus
Verified step by step guidance1
Step 1: Begin by understanding the function of each organelle listed in the options. Recall that organelles are specialized structures within eukaryotic cells that perform specific functions.
Step 2: Analyze the function of the vacuole. Vacuoles are membrane-bound organelles primarily responsible for storing substances such as food, water, and waste products. In plant cells, the central vacuole also helps maintain turgor pressure.
Step 3: Examine the ribosome. Ribosomes are not involved in storage; they are responsible for protein synthesis by translating messenger RNA (mRNA) into polypeptide chains.
Step 4: Consider the mitochondrion. Mitochondria are known as the 'powerhouses' of the cell because they generate ATP through cellular respiration. They are not involved in storage of food or water.
Step 5: Evaluate the Golgi apparatus. The Golgi apparatus is involved in modifying, sorting, and packaging proteins and lipids for transport, but it does not store food or water. Based on this analysis, the vacuole is the correct organelle responsible for storing food and water.
