Telophase In Mitosis And Meiosis (Telophase I, II) Overview What is Telophase? The telophase is both, the last phase of meiosis and the fifth phase of mitosis. Meiosis comprises two stages: telophase I and telophase II. Separation of the duplicate genetic material, which was contained in the nucleus of the parent cells. They eventually divide …

Monocot Vs. Dicot Roots Overview Definition of Monocot Root Monocot roots are fibrous or adventitious roots that develop from the stem and are made up of a large network of thin roots and root fibers. Depending on the type and age of the plant, monocot roots can vary greatly. However, most monocot plants are herbaceous …

Prokaryotic Translation (Protein Synthesis) Overview Translation involves translating the pattern of a messenger RNA (mRNA) molecule into a sequence of amino acids during protein synthesis. Following the transcription of DNA into RNA, ribosomes in the cytoplasm or ER are responsible for protein synthesis. The Ribosomes Normally, ribosomes exist as distinct subunits made up of rRNA …
Phenotype Vs. Genotype Overview Phenotype Definition The word “phenotype” describes all the features that may be seen in an organism due to the interaction between its genotype and its environment. The word “pheno” means to “observe,” hence it is used to describe an organism’s observable traits, such as its height and color. An organism’s phenotype …

Questionnaire Overview A questionnaire includes questions and other elements to elicit data suitable for the study. The questionnaire may be viewed as a paper-based interview. The creation of a questionnaire follows a structure similar to that of the interview schedule. However, due to the questionnaire’s impersonal nature, its development requires even more attention. Due to …
Phylum Coelenterata (Cnidaria) Definition: Phylum Coelenterata (Cnidaria) are defined as diploblastic metazoa having a nematocyst and a single gastrovascular cavity, or coelenteron, as the tissue construction grade. Phylum Coelenterata (Cnidaria) Characteristics They are aquatic, except for a few freshwater species, such as the hydra. They are multicellular and organized at the tissue level. They are …

Trophic Level Definition A collection of species in an ecosystem are classified according to their trophic level. A trophic level defines a place in the food chain. Based on their eating habits, organisms are categorized into several food chains. The trophic level is a stage in the nutritive chain of food chains, which in some …

Epithelial Tissue Definition One of the four kinds of tissue found in animals—the others being epithelial, muscular, connective, and nervous—epithelial tissue is made up of tightly clustered polyhedral cells that adhere strongly to one another to create cellular sheets that fill empty organs and coat the surface of the body. Epithelial tissue comprises cells arranged …
