What is meant by apical meristematic tissue?

Apical meristem, region of cells capable of division and growth in the root and shoot tips in plants. Apical meristems give rise to the primary plant body and are responsible for the extension of the roots and shoots.

What is the function of the apical?

Apical meristems give rise to the primary plant body and are responsible for the extension of the roots and shoots. Lateral meristems are known as secondary meristems because they are responsible for secondary growth, or increase in stem girth and thickness.

What is apical dominance name the hormone that causes it?

The apical bud produces a hormone, auxin, (IAA) that inhibits growth of the lateral buds further down on the stem towards the axillary bud. It was first discovered in 1934 that the plant hormone auxin likely regulates apical dominance.

What hormone is responsible for apical dominance?

Auxin
Auxin is a Greek origin word that means “to grow” in literal terms. Thus, auxins are involved in the regulation of the growth and behavioral processes of the plant. They are the most essential hormones for plant body development. Auxins are responsible for shoot apical dominance seen in the central shoot.

What do you mean by apical?

Apical: The adjective for apex, the tip of a pyramidal or rounded structure, such as the lung or the heart. For example, an apical lung tumor is a tumor located at the top of the lung.

What is apical meristem example?

Krishan T. Shoot apex and Root apex are two common examples of apical meristems.

Which hormone overcome apical dominance in plants?

auxin
Presence of cytokinin in an area causes preferential movement of nutrients towards it. When applied to lateral buds, they help in their growth despite the presence of apical bud. They thus act antagonistically to auxin which promotes apical dominance. Therefore cytokinin can overcome apical dominance, caused by auxins.

What is apical dominance and which hormone is responsible for this?

auxins
