Growth rate
(Science: biology, cell culture, Ecology) The rate, or speed, at which the number of organisms in a population increases.
this can be calculated by dividing the change in the number of organisms from one point in time to another by the amount of time in the interval between the points of time.
The phrase is most often used to describe growth of cells or microorganisms in laboratory cultures and usually expressed as the generation time.
This tutorial describes the sigmoid curve, annual plant growth, tree growth, human growth, and insect growth as the growth curves for the corresponding organisms. Read this tutorial to learn more about the different growth patterns...
This lesson looks at population attributes, regulation, and growth. It also covers population genetics, particularly genetic variations, natural selection, genetic drift, genetic migration, and speciation...
Plants, like animals, produce hormones to regulate plant activities, including growth. They need these hormones to respond well to their environment and to sustain growth, development, and dispersal. Plant biologists recognize five major groups of plant hormones: auxins, gibberellins, ethylene, cytokinins, and abscisic acid. Find out in this guide the importance of each hormone in the life of a plant...
Hormones are produced in the endocrine glands of animals. The pituitary gland and hypothalamus are the most important in regards to the regulation of growth and development. Know the different hormones of animals in this tutorial...
The human body is capable of regulating growth and energy balance through various feedback mechanisms. Get to know the events of absorptive and post-absorptive states. This tutorial also describes the endocrine and neural control of compounds such as insulin and glucagon. It also deals with the regulation of growth, heat loss, and heat gain. ..
