Organelles of a cell play important functions in the daily activities of the eukaryotes or prokaryotes. This article is aimed at discussing what an organelle is, the types and functions of organelles, structure, and examples of organelles. It will also look at the list of organelles (plant and animal organelles) and the …
Membrane bound organelles in a cell are a type of organelles in eukaryotes that help in carrying out the necessary cellular functions. Before we proceed, let’s refresh our understanding of what organelles are. All creatures have a cell that serves as their structural, functional, and biological unit. In these cells, it is …
A vacuole is a membrane-bound organelle found in the cells of plants, fungi, animals, and some protists. However, the prominence of vacuoles is greater in the cells of plants, fungi, and certain protists than in the cells of animals. A vacuole can be defined in biology as a space within a cell …
In order to gain an understanding of plasmolysis in a plant cell or a plasmolysed cell, one needs to know the definition of plasmolysis, examples, importance, types, processes, and causes. This article elaborates more on these. Plasmolysis definition in biology Plasmolysis in plant cells is defined as the constriction of a eukaryotic …
Turgor pressure in plants is the force exerted by stored water on a cell wall. It is also known as hydrostatic pressure and is defined as the pressure in a fluid measured at a specific point within it when it is at equilibrium. Turgor pressure is generally caused by the osmotic flow …
The Gram staining procedure in microbiology is a differential staining technique used to differentiate bacterial cells into gram-positive or gram-negative bacteria based on the differences in their cell wall components. At the end of the gram stain, gram negative bacteria stain pink/ red while gram positive bacteria stain purple or blue. Gram-negative …
Guard cells function mainly in the control of gas exchange in the epidermis of leaves, stems, and other organs. Guard cells function, definition, structure, and location would be discussed. These bean-shaped specialized cells are formed in pairs, with a gap between them forming a stomatal pore. Guard cells, as a result, play an …
There are the main functions of roots in plants as well as some secondary root functions; all these are very important and essential because the roots help the plant carry out essential life processes such as growth, development, and reproduction. Primary function of roots in plants The main function of roots in …
