These are the chemical messengers. The "Big Five" include: Auxins: Promote cell elongation and apical dominance. Gibberellins: Trigger stem elongation and seed germination. Cytokinins: Promote cell division and delay aging.

To start your presentation, it is crucial to distinguish between these two fundamental terms:

Growth slows down as the plant reaches maturity or resources become limited. 3. Meristems: The Engines of Growth plant growth and development ppt download top

Unlike animals, plants have localized regions of active cell division called .

A plant’s journey is dictated by both "nature" and "nurture." Intrinsic Factors (Internal) These are the chemical messengers

Plant growth isn't constant; it follows a specific "S-curve" or . This can be broken down into three main stages:

The response of plants to the duration of light and dark. We categorize plants into Short-Day, Long-Day, and Day-Neutral. Cytokinins: Promote cell division and delay aging

An irreversible, permanent increase in the size of an organ or its parts. It is primarily driven by cell division and cell enlargement.

Found at the tips of roots and shoots. They are responsible for primary growth (length).
