Despite their fundamental similarities, there are some striking differences between animal and plant cells (see Figure 1). Animal cells have centrosomes (or a pair of centrioles), and lysosomes, whereas plant cells do not. Plant cells have a cell wall, chloroplasts, plasmodesmata, and plastids used for storage, and a large central vacuole ...Both plant and animal cells comprise membrane-bound organelles, such as endoplasmic reticulum, mitochondria, the nucleus, Golgi apparatus, and lysosomes. The plant cell can also be larger than the animal cell. The normal range of the animal cell varies from about 10 – 30 micrometres and that of plant cell range between 10 – 100 micrometres.Cell structure: Function: Cytoplasm: ... Chloroplast: Contains the green pigment, chlorophyll, which absorbs light for photosynthesis, and the enzymes needed for photosynthesis. Cell wall:The chloroplast is a member of the cell’s chloroplast family. Chlorophyll, a pigment found in chlorophyll, gives leaves their green hue and absorbs light energy. Chloroplasts play a critical role in chlorophyll production. Chlorophyll is essential for photosynthesis in a variety of ways, and it can be found in a wide variety of colors.

In plants, photosynthesis takes place primarily in leaves, which consist of many layers of cells and have differentiated top and bottom sides. The process of photosynthesis occurs not on the surface layers of the leaf, but rather in a middle layer called the mesophyll ( Figure 10.2.1 10.2. 1 ). The cell wall tends to give plant cells a boxy, rigid structure. Figure 3.8. 1: Elodea leaf cells. The most obvious of the membrane-bound organelles you will see are the chloroplasts. These numerous, green, disc-like structures are responsible for doing photosynthesis, making food for the plant.
