Plant and animal cells both have a nucleus, endoplasmic reticulum, ribosomes, a Golgi apparatus, vesicles, mitochondria and a cell membrane. Each of these components work together to keep the cell healthy and functioning properly. In addition, plant and animal cells are eukarotic, meaning they are multicellular.
The nucleus is located in the center of a cell and it controls a variety of functions. The endoplasmic reticulum, Golgi apparatus and ribosomes work together to process and transport materials into and out of the cell. A vesicle is another part of plant and animal cells that transports particles and substances to and from the cell.
Plant and animal cells also have mitochondria, but they function slightly differently in the different cells. The mitochondria in animal cells release energy and facilitate respiration. In plant cells, mitochondria work with chloroplasts to absorb light and energy.
In addition to having similar kinds of components working within the cell, plant and animal cells both are capable of diffusion. This is a process where dissolved substances pass in and out of the cell. Both kinds of cells also have a cell membrane that is controlled by the nucleus and selectively allows particles and substances to enter the cell.Learn More
The zona pellucida is the transparent, thick outer layer of the ovum in mammals that protects the cell as it travels from the ovary to the uterus. The National Institutes of Health states the layer regulates interactions between ovulated eggs and free-floating sperm as the egg is fertilized. In order to fertilize the egg, sperm must penetrate this outer layer as it thins on the way to the uterus.Full Answer >
Human skin cells contain 46 chromosomes, or 23 chromosome pairs, and after mitosis, the two daughter cells also have 46 chromosomes. Mitosis is a cellular process that creates two identical daughter cells from one original cell.Full Answer >
The consensus among biochemists is that virtually every cell in the human body can break down sugar, usually in the form of glucose, to use as energy. According to the authors of the 5th edition of "Biochemistry," the brain and the kidneys prefer to run on glucose. In fact, the brain favors glucose to such an extent that it only metabolizes other fuel sources after several days of starvation.Full Answer >
The Golgi apparatus is a cellular organelle that is found in most eukaryotic cells, including human cells. It was first identified in 1897 by Camillo Golgi and was named after the physicist the following year.Full Answer >
