Question
Write about the different phases of growth.
Answer
The growth of a plant can be divided into three main phases: cell division, cell enlargement, and cell differentiation.
- Cell division: The phase of active cell division and proliferation by mitosis, leading to an increase in cell number.
- Cell enlargement: The phase where cells elongate and expand, leading to an increase in overall plant size, regulated by the hormone auxin.
- Cell differentiation: The phase where cells specialize and acquire specific functions, forming different types of tissues and organs, influenced by genes, hormones, and environmental factors.
