Cell membranes protect and organize cells. All cells have an outer plasma membrane that regulates not only what enters the cell, but also how much of any given substance comes in. Unlike prokaryotes, eukaryotic cells also possess internal membranes that encase their organelles and control the exchange of essential cell components. Both types of membranes … Read more
What is Stratified Squamous Epithelium? The stratified squamous epithelium is made up of multiple layers of cells, with squamous cells at the apical layer and several layers below it, but cuboidal to columnar cells in the deeper layers. Because the most significant difference between a simple epithelium and a stratified epithelium is the number of … Read more
Definition of Cold Blooded Animals Cold-blooded animals are those that are incapable of changing their body temperature in response to the ambient temperature. These creatures’ body temperatures change when they wander through different environments with varying temperatures. As a result, their body temperature does not remain steady. As a result, these animals are unable to … Read more
Simple Diffusion Definition Simple diffusion is a sort of passive transport that happens when the electrochemical potentials of a solute on opposite sides of a permeable barrier differ. Diffusion refers to the “spreading out” of molecules from a higher concentration in other science areas such as chemistry, but in biology, the process involves a selectively … Read more
Rough Endoplasmic Reticulum The rough endoplasmic reticulum is a form of endoplasmic reticulum that consists of flattened sacs studded on the outer surface with protein-synthesizing particles known as ribosomes. The rough endoplasmic reticulum is a component of the cell’s endomembrane system, which is found in the cytoplasm. Protein synthesis, folding, modification, and transport to other … Read more
What is Interphase / Interphase Definition? Interphase: Cell division is a continual process in which daughters cells emerge, develop, and create their own daughter cells, and the cycle continues. Cell growth and cell division are two events that occur during the cell cycle, with the interphase defining the phase of cell expansion during which various … Read more
What is Carbohydrates ? Carbohydrates are a class of carbonyl compounds (aldehydes or ketones) found in nature that contain numerous hydroxyl groups. It could contain derivatives that, when hydrolyzed, produce comparable compounds. They’re the typical organic molecules in nature, and they’re also referred to as “saccharides.” Sugars are sweet-tasting carbohydrates that dissolve in water. Structure … Read more
Definition of Anaphase This is the phase in which the two identical daughter cells are separated from duplicate genetic components carried in the nucleus of the parent cell. The sister chromatids (replicated chromosomes) are oriented along the cell’s equator on the metaphase plate in the preceding phase, metaphase. As a result, each pair of chromosomes … Read more
Metaphase Definition Metaphase is a cell cycle stage that occurs during both mitosis and meiosis cell division. The chromosomes condense during metaphase in mitosis and meiosis, and they become visible and identifiable during alignment at the centre of the dividing cell, forming a metaphase plate at the cell’s centre. A set of checkpoints ensure that … Read more
Primary Succession Definition Primary succession is a type of ecological succession that occurs in a newly formed ecosystem that lacks habitable soil, but is then colonised by living creatures for the first time. A series of events that occur in order to build a stable ecosystem is known as primary succession. Natural phenomena such as … Read more
