The nucleus stores DNA. The endoplasmic reticulum and Golgi body are involved in protein maturation and transport. Mitochondria generate usable energy for the cell. Chloroplasts carry out photosynthesis. Vacuoles are storage compartments that sequester waste and help maintain water balance. Lysosomes contain enzymes that help break down waste.

All cells have a membrane that separates them from the outside world. Although cells are small, they are not simple. Cells contain different components, such as the cytoplasm, ribosomes, and genetic information in the form of DNA.

For example, mitochondria help release energy that the cell can use for other tasks, and the nucleus contains the genetic information. The cell membrane forms the boundary that controls what enters and leaves the cell. In plant cells, chloroplasts enable photosynthesis and the cell wall provides structure.

However, they differ in certain aspects. For example, plant cells have a cell wall and a central vacuole, while animal cells contain centrosomes. The understanding of these cellular structures continues to evolve through ongoing research.
