write a note on different phases in factorial growth
Answers
Explanation:
There are three phases of growth - meristematic, elongation and maturation. We can understand this better by looking at a seed. ... The cells next to this region represent the elongation growth phase. In this region, there is the formation of new cell walls, vacuoles etc.
Answer:
Alike, animals and humans, plants too, grow in height and size over a period of time.
Plants Growth
Growth is the most fundamental characteristic of all living organism. It is an irreversible and permanent metabolic process. Be it plants, animals, birds or an insect, every simplest, as well as the most intricate living species, undergo the process of Growth-increasing in size.
Plants do have an unique ability to grow continually throughout their life cycle. The entire process of growth and development in plants is carried out by the specialized cells – meristems.
Phases of Growth in Plants
There are three phases of growth – meristematic, elongation and maturation. We can understand this better by looking at a seed. We already know that the tips of roots and shoots exhibit continuous growth and hence are meristematic. The cells in this region are rich in protoplasm and have large nuclei. The cells next to this region represent the elongation growth phase. In this region, there is the formation of new cell walls, vacuoles etc. The region next to the elongation phase represents the maturation phase in which the cells attain their maximal size.
Conditions For Growth
Some of the elements essential for the growth of plants are oxygen, water, and nutrients. Water enters the cells and causes turgidity. This results in enlargement of the cell. Water also provides a medium for activities of enzymes. The metabolic energy required for various activities is obtained from oxygen and sometimes nutrients. Optimum temperature, light, and gravity are also required for the proper growth and development of the plant.
