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

Plant Growth Regulators: Definition, Characteristics, Physiological Effects

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

Krebs Cycle or TCA Cycle: Steps, Product, Equation, Diagram, Significance

Krebs Cycle or Tricarboxylic Acid Cycle or TCA Cycle 

Aerobic Respiration  Glycolysis (Cytoplasm Krebs’s cycle (Mitochondria) Electron transport chain & oxidative phosphorylation It involves complete oxidation of P.A. by removing H Atom, leaving three molecules of CO2, and passing electron removed as part of H-atom to molecular O2 in ETS for ATP synthesis. The first process takes place in the matrix of mitochondria and … Read more

Photosynthesis in Higher Plants: Processes, Light Reaction, C4 pathway, Photorespiration

Photosynthesis occurs in the chloroplast, found in the mesophyll cells of the leaves. There are 4 pigments involved in photosynthesis: Chlorophyll aChlorophyll bXanthophyllsCarotenoids We are all aware of the process of photosynthesis in small plants. Let us have a detailed look at the photosynthesis in higher plants notes to explore the process of photosynthesis in … Read more
