What are the hormones found in plants?
Plant hormones (also known as phytohormones) are organic substances that regulate plant growth and development. Plants produce a wide variety of hormones, including auxins, gibberellins (GA), abscisic acid (ABA), cytokinins (CK), salicylic acid (SA), ethylene (ET), jasmonates (JA), brassinosteroids (BR), and peptides.
How are plant hormones used in agriculture?
Rooting powder contains plant hormones to promote growth. Plant cuttings can be dipped in hormone rooting powder before planting. Synthetic plant hormones are used to control plant growth. For example, rooting powder contains growth hormones that make stem cuttings develop roots quickly.
Which of the following is a plant hormone answer?
Cytokinin is the plant hormone which has a major role in growth and development of the plants. It helps in embryogenesis, cell division, chloroplast differentiation and many other important roles in plants. Therefore, it is clear from above the options that cytokinin is the plant hormone.
What are plant hormones give its example?
plant hormones are also known as phytohormones. the five major plant hormones are auxins,gibberellins,cytokinins,abscisic acid,and ethylene. these hormones will work independently or together to influence plant growth and health. Auxins and gibberellins help promote plant growth,particularly in stem elongation.
How many plant hormones are there?
There are five major types of plant hormones: auxins, cytokinins, gibberellins, ethylene and abscisic acid. Each hormone has a distinct job and for oilseed, pulse and cereal crops, auxins and cytokinins can greatly improve plant vigor, promote growth of roots and shoots and reduce stress.
What are plant hormones answer for class 10th?
Plant hormones are chemicals present in plants which help to coordinate growth, development and responses to stimuli and environment. For example, auxins, gibberellins, cytolcinins, abscisic acids are different plant hormones.
What are plant hormones 10th?
Plant hormones are chemical compounds present in very low concentration in plants. They are derivatives of indole (auxins), terpenes (Gibberellins), adenine (Cytokinins), carotenoids (Abscisic acid) and gases (Ethylene). Roles of different hormones can be complementary or antagonistic.
