Biochemistry MCQ-11: Membrane lipids are a type of lipid that are important components of cell membranes. The main types of membrane lipids are phospholipids, galactolipids, sphingolipids and cholesterol. The composition of membrane lipids can vary between different types of cells, and can be influenced by factors such as diet and […]
Meristematic vs Permanent Tissues Tissue is a group of cells with more or less common origin and doing a specific function. Plant tissues are broadly classified into two categories based on their capacity of cell division. They are (1) Meristematic tissues and (2) Permanent tissues. Meristem is a type of […]
What is Meristem? Meristem is a group of plant cells that remain in a continuous state of division. It is a tissue system in plants called meristematic tissue. The term meristem was proposed by Karl Nägeli from a Greek word ‘merizein’ which means ‘to divide’. The meristem composed of rapidly […]
Biochemistry MCQ-10: Fatty acids are a type of lipid that are used as a building block for other lipids in the body. They consist of a long hydrocarbon chain with a carboxyl group at one end. The hydrocarbon chain can be either saturated (no double bonds) or unsaturated (one or […]
Animal fats vs Plant Fats Fats, oils and waxes are the general terms describing a structurally diverse bio-macromolecule called ‘lipids’. Lipids are esters of glycerol and fatty acids. One glycerol molecule is esterified with three fatty acid residues to form a triglyceride. Physical, chemical and structural diversity of fats varies […]
