उत्तर
A plant cell is the building block of a plant's body. It has a cell wall, which gives the cell a strong and firm shape. Just inside the cell wall is the cell membrane, which controls what goes in and out of the cell.
The inside part is filled with cytoplasm, a jelly-like fluid where all cell parts float. The nucleus is the control centre, helping the cell function properly. The vacuole stores water, food, and waste; in plant cells, it is usually large.
Chloroplasts are present to help the plant make its own food using sunlight (photosynthesis). Mitochondria are the powerhouses of the cell; they produce energy. The Golgi body helps in packaging and sending materials. The endoplasmic reticulum transports proteins, and ribosomes help make them.
