Ethylene is a gaseous plant hormone. The main effects of ethylene are: It induces the ripening of fruits. It increases the respiration rate in... View Article
Ethylene is a gaseous plant hormone. It hastens the ripening of fruits. Plants show a sudden increase in the production of ethylene when they... View Article
Products of redifferentiation in plants are secondary xylem, secondary phloem, secondary cortex (phelloderm) and cork (phellem). Also Check:... View Article
The main advantage of cell differentiation is that cells become specialised to perform specific functions efficiently. E.g. the cell loses its... View Article
Dedifferentiation is the process by which the differentiated cells regain their capacity to divide, e.g. interfascicular cambium and cork cambium... View Article
During cell differentiation, the unspecialised cells mature and evolve to perform a specific function. This occurs due to differential gene... View Article
Redifferentiation is the process by which dedifferentiated cells again lose their capacity to divide and mature to perform a specific function.... View Article
Abscisic acid or ABA is a plant growth inhibitor. It is involved in the stress response and induces dormancy. It is produced in the roots and... View Article
Abscisic acid is known as dormin because it induces dormancy. It inhibits plant growth and increases tolerance to various kinds of stresses. By... View Article
Kinetin is a type of cytokinin. It promotes cell division. It was first isolated from autoclaved herring sperm DNA. It is a modified adenine... View Article
Auxins are used in agriculture for various purposes. E.g. Auxins are used in plant propagation to stimulate rooting in stem cutting. They... View Article
No, gibberellins delay senescence. Gibberellins delay fruit ripening and senescence along with improving its shape and size. So the fruits can be... View Article
Ethylene is produced by all the fruits. It is a gaseous plant hormone. The level of ethylene is very low when the fruit is in an unripe state.... View Article
Differentiation in plants is open because they retain the capacity for unlimited growth throughout their lifespan. It is due to the presence of... View Article
Tumour is a product of dedifferentiation. Tumour is formed when a differentiated cell regains the capacity to divide and shows unrestrained... View Article
Differentiation refers to the process of maturation, where an unspecialised cell becomes specialised to perform a specific function. E.g. apical... View Article
Sclereids are a kind of sclerenchyma cells that are irregular or short. These are dead cells. Their walls are irregular, very thick and their... View Article
Vessels are elongated tube-like structures typically proper to conduct solutes and water. They are composed of a row of cylindrical cells... View Article
