Monocot Flower and Dicot Flower: Definition, Structure, Differences, Examples

Monocot and Dicot Flower: Definition, Structure, Differences, Examples

Definition of Monocot Flower Monocot flowers are compressed shoot areas with particular sexual reproductive functions. The greatest distinguishing feature of monocot flowers is that their flower parts are frequently arranged in threes or multiples of threes. The analysis of flowers and their components can therefore be used to distinguish among monocot and dicot plants. Despite … Read more

Photoperiodism, Vernalisation And  Seed Dormancy 

What is Photoperiodism ? Photoperiodism refers to the response of plants to the lengths of dark and light periods. Many angiosperms, or flowering plants, have a protein that can sense seasonal changes in light. A plant will flower depending on these changes in light levels. “Photoperiodism may be defined as the response of plants and … Read more

Plant Growth Regulators: Definition, Characteristics, Physiological Effects

Plant Growth Regulators Definition Plant growth regulators may be defined as any organic compounds, which are active at low concentrations (1-10 ng / nl) in promoting, inhibiting or modifying growth and development. The naturally occurring (endogenous) growth substances are commonly known as plant hormones, while the synthetic ones are called growth regulator. Plant hormone is … Read more

Differentiation, Dedifferentiation, and Redifferentiation : Example

Differentiation, Dedifferentiation, and Redifferentiation – Differentiation 

Differentiation, Dedifferentiation, and Redifferentiation – Differentiation  Cells from root apical & shoot apical meristem & cambium differentiate & mature, cells undergo structural changes (cell wall + protoplasm). E.g., to form a treachery element, cells lose protoplasm, develop strong, elastic, lignocellulosic 20 cell walls which carry water under extreme tension & long distance. Plants cells are … Read more
