Gram positive and gram negative bacteria fall under the study of microbiology. The difference between gram positive vs gram negative bacteria is based on their staining color during the gram stain test. Using the gram staining technique, bacteria have been differentiated into gram-positive and gram-negative bacteria. The ability to differentiate bacterial cells …
Organisms exhibit a behavioral adaptation known as Batesian mimicry in order to survive and escape predation. Many examples of Batesian mimicry can be seen in animals and plants around us. In nature, mimicry is a behavioral adaptation whereby organisms evolve to resemble another organism or object. This adaptation is done in order …
Not all organisms are multicellular, some organisms exist as just a single cell and are called a single-celled organism or a unicellular organism. Cells come together to form multicellular organisms like plants and animals and that is why we call cells, the building blocks of life. However, in microbiology unicellular organisms are …
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 …
