Cell MCQ Question Answer
Hello students, our topic for the MCQ is ‘Cell’. Before discussing about cells we need to know two types of cells are there one is animal cell and other is plant cell. The cell structures are different because animal and plants do different functions. There are various parts in plants cell and animal cell. Some parts of the cell are mitochondria, cytoplasm, Golgi bodies, nucleus, chromatin etc. There are some parts of the cell which is present only in plant cell not in the animal cell like cell wall, chloroplast, large vacuoles.
