How genetic and environmental factors affect plant growth and development and factors that affect the growth of organisms?
The genotype of a plant affects its growth. As selected varieties of rice grow rapidly, maturing within 110 days, whereas others, in the same environmental conditions, grow more slowly and mature within 155 days. A producer has control over the genetic factor by his choice of variety. Some of the factors which influence the growth of different living organisms can be divided into two distinct categories, which include internal and external factors. Internal factors include heredity, enzymes, and hormones while the external factors include light, water, temperature, and minerals or nutrients.
Genetic character of any plant is an internal order derived through the process of pollination. If one looks at this process, it is complicated in itself. In addition to this, environment has a tremendous influence on them initially, the morphology of the plant, but over a period of time this gets into the plant system transforming it differently - that is how new varieties and species are evolved over a period of time.
Growth occurs due to the synthesis of more protoplasm, cell division, cell enlargement, and cell differentiation. This process of growth is influenced by all those factors which influence biosynthetic machinery. Food, nutrients, water, oxygen, optimum temperature, optimum light, minerals, gravity, etc. There are two main factors that influence an organism's growth; these are genetic and environmental factors. Genetic factors are the genes the organism gets from its parent or parents. While environmental factors are the conditions and organism is exposed to as it grows. The rate of growth or death of a particular microbial species is influenced by a variety of physical factors in its environment including temperature, osmotic pressure, pH, and oxygen concentration.
