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 …
Organisms exist on earth as either unicellular or multicellular organisms. The difference between unicellular vs multicellular organisms is based on the number of cells and how they carry out their cellular activities. Technically, unicellular and multicellular organisms are the two kinds of organisms found on earth. Unicellular organisms are usually prokaryotes, which …
The meaning of homeostasis is the condition the body system undergoes in order to maintain its internal environment. Some examples of homeostasis in the body can be seen in the regulation of body temperature, maintenance of blood glucose level, and the defense of a bacterial or viral infection. Homeostasis meaning Homeostasis refers …
Organisms exist on earth as either unicellular or multicellular organisms. Unicellular and multicellular organisms’ examples and characteristics vary based on their structure and how they carry out their cellular activities. In multicellular organisms, life begins as a single cell until mitosis occurs, causing growth and development. According to evolution, the development of …
Autotrophs in ecology are organisms that produce or manufacture their food and these include plants, algae, and cyanobacteria which are some of the autotrophs examples. Almost all autotrophs get their energy from the sun (light) or from inorganic substances (chemical). Autotrophs meaning Autotrophs are also known as primary producers. They are organisms …
In heterotrophs, energy for life processes is obtained through the consumption of autotrophs. Some heterotrophs examples include members of the second and third trophic levels in an ecosystem. This article will discuss the types of heterotrophs, their meaning, and their role in ecology. Heterotrophs meaning Heterotrophs are living things that cannot produce …
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 …
