The following points highlight the four main types of vacuoles. The types are: 1. Sap Vacuoles 2. Contractile Vacuoles 3. Food Vacuoles 4. Air Vacuoles. Type # 1. Sap Vacuoles: They are fluid filled vacuoles or vesicles which are separated from the cytoplasm by a selectively permeable membrane called tonoplast. It has a number of transport systems for the passage [...]
The following points highlight the two types of micro-bodies. The types are: 1. Peroxisomes 2. Glyoxysomes. Micro-Bodies: Type # 1. Peroxisomes: They are micro bodies which contain enzymes for peroxide biosynthesis. Peroxisomes were discovered by De Duve (1965) with the help of fractionation technique. The term was coined by De Duve in 1969. Peroxisomes are found in both plant and [...]
The following points highlight the three main types of cytoskeletal structures of eukaryotic cell. The types are: 1. Microfilaments 2. Intermediate Filaments 3. Microtubules. Cytoskeletal Structure of Eukaryotic Cell: Type # 1. Microfilaments: They are ultramicroscopic long, narrow cylindrical rods or protein filaments which occur in eukaryotic plant and animal cells. Microfilaments are made up of actin (also present in [...]
