Chapter 15 (PLANT GROWTH AND DEVELOPMENT)

What is the short note of plant growth and development?
The plant cells grow in size by cell enlargement which in turn requires water.
Turgidity of cells helps in extension growth.
Thus, plant growth and further development is intimately linked to the water status of the plant.
Water also provides the medium for enzymatic activities needed for growth.
Is growth measurable class 11 notes?
15.
2) Growth is Measurable
At the cellular level, growth is defined as a rise in protoplasm.
This rise is difficult to measure.
Hence, we can track the growth of the cell, its number, and its size.
The increase in fresh weight, length, dry weight, area, volume, and cell number determines growth.
What are the stages of plant growth and development?
The stages that plants go through are from seed to sprout, then through vegetative, budding, flowering, and ripening stages.
Similarly, the nutritional needs of people and plants change as they grow.
Conclusion.
Plants grow through a combination of cell division and cell growth.
Cell division increases the number of cells through cell mitosis, and cell growth increases the cell size.
The growth phases are divided into 3 phases: The meristematic phase, elongation phase, and maturation phase.
