Osmoregulation in cells is critical to the biology of every living thing. Its meaning in biology and some examples like osmoregulation in fish and humans will be discussed in this article. Osmoregulation definition in biology Osmoregulation is defined as the process by which the human body maintains a proper electrolyte balance in …
Endocytosis and exocytosis are examples of bulk transport mechanisms used to move materials into or out of the cell. The exocytosis process function in transporting molecules and substances that are too large to directly pass through the lipid bilayer of the cell membrane. The cell membranes of organisms are semi-permeable and thus …
What is chlorophyll? Chlorophyll is the molecule or pigment in a cell that makes plants have a green color. In this article, chlorophyll will be explained with respect to the types, its structure, and ultimately the benefits of chlorophyll in humans and plants. Chlorophyll definition Chlorophyll is defined as a molecule produced …
The cytoskeleton simply means the skeleton of the cytoplasm of a cell. The cytoskeleton functions to help support all these internal organs in the cell with its structure and it can also be found in all cells, though the proteins that make it up differ between organisms. Cytoskeleton meaning The cytoskeleton is …
The phases of cell division occur in various stages of the cell cycle. These stages of cell division help in the production and maintenance of cells, tissues, and organs. The different types of cells that are involved in cell division will be discussed with appropriate diagrams and pictures. Definition of cell division …
Plastids function largely in the production and storage of food in plant cells. As a result, they participate in activities like photosynthesis, amino acid and lipid synthesis, and material storage, among other things. Biologists thought that the mitochondria formed before plastids and this is because endosymbiosis (a symbiotic connection in which one …
The contractile vacuole function in a cell is the structure for the regulation of water levels. This organelle is found mostly in single-celled organisms that lack a cell wall. Basically, the function of the contractile vacuole is to expand and contract in order to regulate the water levels in and outside the …
The main function of the plasma membrane is to enclose the cell and protect it from dehydration or external harm. Other plasma membrane functions would be discussed below. It is also known as the cell membrane. This membrane covers or encloses the organelles from the rest of the cellular environment. Definition of …
