Description

Here is a concise outline of the key topics covered in the chapter “Plant Growth and Development” for Class 11 Biology, tailored for NEET preparation:

 

 

 

 

Introduction to Plant Growth

 

 

 

 

Definition and phases of growth (cell division, cell enlargement, cell differentiation)

 

Conditions for growth (water, nutrients, light, temperature, oxygen)

 

Growth Curves

 

 

 

 

Sigmoid growth curve (lag phase, log phase, stationary phase)

 

Quantitative comparisons of growth (absolute growth rate, relative growth rate)

 

Measurement of Growth

 

 

 

 

Techniques to measure growth (increase in cell number, cell size, fresh weight, dry weight, length, area, volume)

 

Plant Growth Regulators (PGRs)

 

 

 

 

Types of PGRs and their functions:

 

Auxins: Discovery, functions, synthetic auxins

 

Gibberellins: Discovery, functions

 

Cytokinins: Discovery, functions

 

Ethylene: Discovery, functions

 

Abscisic Acid (ABA): Discovery, functions

 

Photoperiodism

 

 

 

 

Definition and types (short-day plants, long-day plants, day-neutral plants)

 

Role of phytochrome in photoperiodism

 

Vernalization

 

 

 

 

Definition and significance

 

Mechanism and examples

 

Seed Dormancy

 

 

 

 

Causes of seed dormancy

 

Methods to break dormancy

 

Senescence and Abscission

 

 

 

 

Definition and significance

 

Factors affecting senescence and abscission

 

Development

 

 

 

 

Definition and distinction between growth and development

 

Differentiation, dedifferentiation, and redifferentiation

 

Plasticity in plant development

 

Physiology of Flowering

 

 

 

 

Role of light and temperature in flowering

 

Molecular basis of flowering (Florigen theory)

 

These topics cover the essential aspects of plant growth and development, crucial for understanding how plants grow and respond to their environment, and preparing for Neet
