Fig. Most of the tissue in leaves is comprised of parenchyma cells, which are the sites of photosynthesis, and parenchyma cells in the leaves contain large quantities of chloroplasts for. In plant cells, vacuoles of different sorts are known to have different origins, with the endoplasmic reticulum, the Golgi apparatus, and the plasma membrane being involved. The nucleus is basically a headquarters for a eukaryotic cell. 506 Words 3 Pages. This makes it easier for the substances to move around inside a cell, gives cells their shapes, and helps keep the structures inside a. Plant cells for example, contain structures such as a cell wall and chloroplasts that are not found in animal cells. Test your knowledge on plant and animal cells! Apart from the cell wall, there are other organelles that are associated with different cellular activities. They reproduce over a long period of time without changing.
