Artwork showing plant cell structure 插畫檔

Illustration of the structure of a plant cell. The cell nucleus is the large sectioned sphere. It holds the cell's genetic material in the form of DNA (deoxyribonucleic acid). At its centre is a nucleolus, which is responsible for producing components of ribosomes, the cell's protein-manufacturing organelles. Surrounding the nucleus is the endoplasmic reticulum (ER). Some parts of the ER are studded with ribosomes (red). Also featured is the Golgi body (white), associated with the storage and subsequent transport of proteins produced by the ER, and mitochondria (yellow/green), the sites of energy synthesis within the cell. What differentiates a plant cell from an animal one, however, are the chloroplasts, which deal with photosynthesis. The cell wall of the plant is also regular, enabling them to be 'tiled' to form larger structures
