Joseph Foster 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 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 …
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 …
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 …
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 …
