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.Know More
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 in Biology
Some of the primary functions of proteins include their enabling the biochemical reactions that help digest food and respond to stimuli, replicating DNA and providing the structural building blocks for muscles, skin and other tissues. Acting as catalysts, enzymes are the protein-based molecules that play an important role in a wide range of organic processes. Proteins also help to transport nutrients and vital substances, one example being hemoglobin, which transports oxygen throughout the bloodstream.Full Answer >
Some of the key functions of protein involve energy production, transportation, boosting the immune system and replenishing body tissue. Proteins are some of the most essential nutrients for human beings, and they can be obtained from foods such as fish, chicken, eggs and beans.Full Answer >
