What is the meaning of isolation of protoplast?
An isolated protoplast is a plant cell in which the outer wall has been removed mechanically or enzymatically. The results of this wall removal are that the plasma membrane remains the only barrier between the cell cytoplasm contents and the external environment.
Which media is used for protoplast culture?
Protoplast is generally culture in semi-solid Agar medium or Liquid medium.
What are the types of protoplast culture?
There are different methods of protoplast culture such as liquid culture, agar culture, droplet culture, co-culture, hanging droplet culture, immobilised/bead culture and feeder layer technique (Fig. 20.4A-D).
Why protoplast isolation is done?
Protoplasts are cells which have had their cell wall removed, usually by digestion with enzymes. This makes the cell walls easier to digest. Debris is filtered and/or centrifuged out of the suspension and the protoplasts are then centrifuged to form a pellet.
Who is the father of tissue culture?
Gottlieb Haberlandt
Tissue culture is an artificial method involving in-vitro cultivation of plant cells, tissue, or organs in nutrient solutions under controlled lab conditions. It was first discovered in 1898 by a German botanist, Gottlieb Haberlandt.
What is the difference between protoplast culture and tissue culture?
Tissue culture, also called as, callus culture, is a technique that utilizes the fragments of plants and cultures them in nutrient media under suitable artificial environmental conditions. Protoplast culture is the isolation of protoplasts by mechanical and enzymatic methods.
Who defined protoplasm?
Who coined the term protoplasm? J.E. Purkinje coined the term protoplasm.
What are the steps of protoplast culture?
The procedure broadly involves the following steps (Fig. 44.2):
- Sterilization of leaves.
- Removal of epidermal cell layer.
- Treatment with enzymes.
- Isolation of protoplasts.
Who is the father of cells?
George Emil Palade
The Nobel laurate Romanian-American cell biologist George Emil Palade is popularly referred to as the father of the cell. He is also described as the most influential cell biologist ever.
Who is the father of micropropagation is?
Frederick Campion Steward
Micropropagation/Inventors
Cornell University botanist Frederick Campion Steward discovered and pioneered micropropagation and plant tissue culture in the late 1950s and early 1960s.
