Phenotype Definition In genetics, phenotype refers to all observable features in organisms that are the outcome of the genotype’s interaction with the environment. Phenotype is derived from the Greek word pheno, which meaning “observation.” Phenotypes are used to describe observable features in animals such as height and colour. A phenotype describes an organism’s morphology, physical … Read more
Definition of Cladogram The graphical representation of the potential relationship (phylogenetic relationship) between distinct groups of species is called a cladogram. It is used to discover the evolutionary link between organisms through phylogenetic analysis. The cladogram is made up of the Greek words clados and gramma, which represent “branch” and “characters,” respectively. Only the topography … Read more
The animal kingdom has been isolated into two subgroups: Vertebrates and Invertebrates. The vertebrate column which is also referred to as the backbone is present in some animals, those animals are known as vertebrates. Those animals that do not contain backbone or vertebrate column are known as invertebrates. What is Invertebrate ? Invertebrates can be … Read more
Vacuoles Definition: A vacuole is a film-bound organelle that is available in all plant and contagious cells and some protist, creature, and bacterial cells. The most prominent compartment in most plant cells is an extremely huge, liquid-filled vacuole. Huge vacuoles are likewise found in three genera of filamentous sulfur microorganisms, the Thioploca, Beggiatoa, and Thiomargarita. … Read more
Cell Wall Definition Around the inner plasma membrane, an outermost layer provides protection and strength to the cell. This outermost layer is the cell wall. Protoplast, a living structure, forms the non-living cell wall. The cell wall is not a characteristic of all types of cells. Some cells show their presence like plant cells, fungi, … Read more
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
