Definition of plant cell Plant cells are eukaryotic cells, that are found in green plants, photosynthetic eukaryotes of the kingdom Plantae which means they have a membrane-bound nucleus. They have a variety of membrane-bound cell organelles that perform various specific functions to maintain the normal functioning of the plant cell. Structure of Plant cell Generally, plant cells are a lot …

Animal Cell- Definition, Structure, Parts, Functions and Diagram

January 26, 2021February 15, 2020 by Faith Mokobi

Definition of animal cell Animals are a large group of diverse living organisms that make up to three-quarters of all species on earth. With their ability to move, to respond to stimuli, respond to environmental changes and adapt to different modes of feeding defense mechanisms and reproduction, all these mechanisms are enhanced by their constituent elements in the body. However, …

Mitochondria- Definition, Structure, Functions and Diagram

February 9, 2020November 14, 2018 by Sagar Aryal

Mitochondria Definition Mitochondria are oxygen-consuming ribbon-shaped cellular organelles of immense importance floating free throughout the cell. They are known as the “powerhouse of the cell” since these organelles supply all the necessary biological energy to the cell by oxidizing the substrates available. The enzymatic oxidation of chemical compounds in the mitochondria releases energy. Since mitochondria act as the power-houses, they …

Isolation of Mitochondria from Cell Culture

Mitochondria are central organelles controlling the life and death of the cell. They participate in key metabolic reactions, synthesize most of the ATP and regulate a number of signaling cascades, including apoptosis. Investigating functional mitochondria that have been isolated from different tissues and from cultured cells offers a full understanding of mitochondrial function. Mitochondria can be isolated from a variety …

Extranuclear Inheritance- Cytoplasmic Factors and Types

February 4, 2021October 30, 2018 by Sagar Aryal

Though, the genes of nuclear chromosomes have a significant and key role in the inheritance of almost all traits from generations to generations, they altogether cannot be considered as the sole vehicles of inheritance. Certain experimental evidences suggest the occurrence of certain extranuclear genes or DNA molecules in the cytoplasm of many prokaryotic and eukaryotic cells. Bacterial cells such as …
