In daily lfe, we can observe the presence of growth, as in plants which grow taller and bigger gradually. The permanent change in animals and human can only be observed in the increase in height, but not in weight. the weight of animals and human always changes; it increases and decreases sometimes.
How can find out the growth of an organism?Growth process in living irganisme can be observeb from the increase in haight, weight, width and volume. It indicates the addition in cell content or body tissues (biomass). Plant biomass comes from photosynthesis products and nutrient absorption. Photosynthesis product is amylum (starch) and the nutient is mineral which forms and composes the body of the plant, such as the cell walls and some other cell contents.
Animals and humans form their body biomass from their nutritious foods and drinks. To compensate the biomass addition, the body provides enough cells to load it by dividing cells.
Which part of an organism affects growth and development?
There is a tissue in stem and root tips which always actively divides.It is called apical meristem tissue. The growth in these tips is also known as primary growth. Stem and root, thus, can grow longer.
Discotyedons have stems that can grow larger because it has lateral meristem (cambium), which actively divides between bark and wood.
In grass family (Graminae), the stem nodes can elongate. It is caused by the presence of intercalary meristem, which actively divides, located in base of nodes. In some monocotyledons such as coconut trees and king palms, the stem can enlarge. The enlargement can occur due to the presence of secondary growth causedby monocotyledon cambium.
Our body and the vertebrate body can grow taller and bigger.The growth happens in skeleton (bones) and other tissues concurrenly. The bone growth occurs especially in pipe and long bones. The center of growth in the pipe bone is in epiphyse disc. In Avertebrates, the growth occurs in their whole body.
