Growth and development !! 

What is Growth ? 

Growth can be defined as irreversible permanent increase in size of an organ or its part of even of individual cells.

Types of growth / stages of growth :- 

1. Vegetative growth :- 

the early growth of plant producing date stamp and branches without power is called vegetative growth.

2. Reproductive growth :- 

After the vegetative growth plant produce flowers which is the reproductive part of plant this is called reproductive growth phase.


Growth curve sigmoid growth curve !? 

It is an s-shaped curve obtained when we plot growth against time. 

It is also called sigmoid growth curve.

 mainly shows four phases of growth :- 

1. Initial slow growth. ( Lag Phase). 

2. Derive a period of growth log phase grand period of growth exponential phase where maximum growth is seen in short period. 

3. The diminishing face were growth will slow .

4. Stationary/steady phase where finally growth stop.

What is development ?

It is overall term which refer to the various changes that occur in plant during its life cycle.

Development stages :- 

Germination and emergence 

seedling growth

 Maximum vegetative growth stage

 Primordial differentiation

 flowering stage

 fruit growth

 fruit maturity 

physiological maturity

 harvest maturity


Factor affecting growth and development ;- 

Germination

 temperature

 soil moisture 

depth of sowing.

 seedling growth.

 leaf growth .

tillering and branching.


Difference between growth and development - 


Growth :- 

Growth is quantitative .

growth is limited period.


Development :- 

Development is quantitative as well as qualitative.

Development take place till death.

                          Bryophytes  • Bryophytes include the various mosses and liverworts that are found commonly growing in the most shaded area in hills.  It is also called Amphibians of the plant kingdom.   Water for sexual reproduction.   It plays important role in plant succession on bare rocks / soils.   Root – like, leaf – like or stem – like structure.   \the male sex organ is called antheridium. They produce biflagellated antherzoids. The female sex organ archegonium is flask – shaped produces a single eggs.   Zygote do not undergo reduction division immediately.   Species of Sphagnum, a moss , provide peat.   Mosses along with lichens one the first organisms to colonise rocks.   Great ecological importance.   Reduce the impact of falling rain and prevent soil erosion.   The Bryophytes are divided into liverworts and mosses.  Live...
