what is cytoplasm and Mitochondria??
Answers
Answer:
Cytoplasm is the gelatinous liquid that fills the inside of a cell. It is composed of water, salts, and various organic molecules. Some intracellular organelles, such the nucleus and mitochondria, are enclosed by membranes that separate them from the cytoplasm.
Answer:
Cytoplasm is the inner content of the cell membrane which separates the cell membrane from the nucleus. It is composed of cytosol, organelles and inclusions. Cytosol is the soft, sticky and semi-transparent fluid in which various cell organelles are suspended. Cytoplasm is not a simple clear fluid. Rather, it is a complex viscous fluid that contains 70% water. The remaining portion is made up of proteins, carbohydrates and lipids.
In most eukaryotic cells, double-membrane-enclosed organelles known as mitochondria are present in the cytoplasm. Mitochondria are responsible for the production of most of the energy in cells. For this reason they are also known as the powerhouse of cells. The energy released by mitochondria is stored in the form of ATP molecules. The number of mitochondria in a cell is dependent upon the nature of the physiological activity carried out by it. For example, in humans, the red blood cells do not contain any mitochondria, while liver and muscle cells may contain hundreds or even thousands of them.
