Plant Tissue Culture — Flashcards

Answer

Cellular totipotency is the ability of a single plant cell to divide and differentiate into a complete, fully functional plant under suitable conditions. This means every living plant cell has all the…

Answer

The term 'totipotency' was coined by Morgan in 1901 to describe the capacity of a cell to regenerate into a complete organism. In plants, this concept explains how a single cell from an explant can de…

Answer

Totipotency is the fundamental principle behind plant tissue culture because it allows scientists to grow entire plants from small pieces of tissue (explants). Since each cell has the potential to bec…

Answer

A nutrient culture medium is an artificial mixture that provides all essential nutrients required for the growth and development of plant cells, tissues, or organs in a lab. It contains macro and micr…

Answer

The most commonly used nutrient medium is Murashige and Skoog medium, also known as MS medium. It contains a balanced mix of nitrogen, potassium, magnesium, and other essential elements, along with vi…

Answer

A basal medium contains only the basic nutrients like minerals, vitamins, and sugars but does not include any plant growth regulators. It is used for germinating seeds or growing callus. A complete me…

Answer

Agar is added to the nutrient medium to solidify it, providing a stable surface for the explant to grow. It acts as a support structure similar to soil, allowing the plant tissue to remain in place wh…

Answer

The ideal pH range for a plant tissue culture medium is between 5.6 and 6.0. This slightly acidic condition ensures optimal nutrient availability and enzyme activity for plant cell growth. The pH is a…
