Direct link to Adrija Roy's post Yes, bacteria do attack p, Posted 7 years ago. Ribosomes consist of RNA and proteins and they help with synthesizing proteins. Most of the plant cells volume depends on the water level in its vacuole. The main purpose of a vacuole in bacteria is to have a use in storage of various ions and help in water balancing inside the cells. Vacuoles have a simple structure: they are surrounded by a thin membrane and filled with fluid and any molecules they take in. Sharing is caring! They are found mostly inplant cellsandfungi. In both exocytosis and endocytosis, the vacuoles are essentially storage vesicles that contain, transport, and dispose of proteins, lipids, and other molecules. Storage proteins accumulate primarily in the protein storage vacuoles (PSVs) of terminally differentiated cells of the embryo and endosperm and as protein bodies (PBs) directly assembled within the endoplasmic reticulum (ER). Cell turgor is the level of hydrostatic pressure against the cell wall of the plant cell. Most mature plant cells have one large central vacuole that typically occupies more than 30% of the cells volume.
