The cell wall, which is for support and protection, could be the outside covering, perhaps the bricks on the facade of the school. The mitochondria, powerhouse of the cell oxidizes glucose to release energy in the form of A.T.P. Energy is released in a school by the oil burner in the basement. Ribosomes synthesize proteins according to the messenger RNA instructions. Students carry out tasks and produce work, according to the daily aim under direction by the teacher. Vacuoles can store water and food. They can be compared to a refrigerator or supply closet. The nucleus, which contains all the hereditary information, can be compared to the computer system or library within the school. The nucleolus manufactuers rRNA. This can be compared to a copy machine making copies as the nucleolus transcribes rRNA according to genetic instructions. The endoplasmic reticulum, is for intracellular transport and is a system of tubules. This can be compared to the hallways inside a school. The golgi apparatus packages cell secretions and makes them ready for transport. This can be compared to the teacher collecting and grading school work from students and making it ready to be displayed on a bulletin board. The cell membrane allows materials in or out of a cell selectively. This can be compared to the security at the front desk of a school. The chloroplast absorbs radiant energy to make it available for photosynthesis. Solar panels on the roof of a school could be a comparison.
what if i have the storage closet as vacuole?
