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 below mentioned article provides biology notes on Cytoplasmic Matrix. Cytoplasm is jelly-like semi-fluid general mass of protoplasm excluding the nucleus but including all other components— cytoplasmic matrix, cell organelles and cell inclusions. (A) Cytoplasmic Matrix or Cytosol (Hyaloplasm): It is the clear fluid part of the cytoplasm which can exist in two states, sol and gel. The two are [...]
The following points highlight the two main cases of cytoplasmic inheritance. The cases are: 1. Inheritance of Plastids 2. Kappa Particles of Paramoecium. Cytoplasmic Inheritance: Case # 1. Inheritance of Plastids: The cytoplasm of plants bears minute pigments called plastids. Plastids arise from smaller DNA particles of the ovum and multiply by division. During the formation of gamete a plastid [...]
