The vacuole in cells have three main functions which are to provide the plant with support or rigidity, a storage area for nutrients and waste matter and can decompose complex molecules, according to British Society for Cell Biology. In plant cells, the vacuole also can store water. Plant and animal cells can contain vacuoles, which are fluid-filled sacs enclosed by a membrane wall, reports Biology4Kids.Continue Reading
In plant cells, vacuoles can occupy up to 90 percent of a cell's volume. Similarly, vacuoles of plant cells are larger than those in animal cells, states the British Society for Cell Biology. The membrane that encloses a vacuole is called a tonoplast.
Besides vacuoles, some other organelles or structures found in both animal and plant cells are cytoplasm, endoplasmic reticulum, nucleus, ribosomes, mitochondria and Golgi vesicles.Learn more about Biology
Blood, a liquid made up of plasma and cells, has several functions including controlling body temperature, supplying oxygen and nutrients, removing waste, assisting the immune system and transporting hormones. Blood cells, red and white, are made in bone marrow. Plasma is 90 percent water but contains dissolved substances such as hormones, electrolytes, vitamins and proteins.Full Answer >
Plant cell vacuoles serve the same vital storage functions for nutrients, water and wastes as those in animal cells but are much larger because they also provide structural stiffness in combination with the plant's cell walls. This is why water-starved plants droop; their cells have essentially deflated. If a living but wilted plant once again receives sufficient water, it regains its former stiffness as the vacuoles refill.Full Answer >
According to the Florida State University, vacuoles are responsible for storage, waste disposal protection and growth within a plant cell. in older plants the vacuoles are usually large and are important in providing structural support.Full Answer >
Amoebas excrete particles of waste from anywhere on their surface, and most rid themselves of excess water by active pumping from an organelle known as the contractile vacuole. Amoebas have no mouth or anus, and they can also take in food particles anywhere on their cellular membranes.Full Answer >
