The external factors affecting growth and development are: Light – Plants do photosynthesis to transform the energy obtained from light into chemical energy, which can then be utilized to carry out other activities.

As a result, it leads to an extension in the length of the plant. The process of development is the one in which an organism or a plant experiences full mental growth and maturity. Cells undergo specialization by alteration of gene expression. Notify me of followup comments via e-mail, Written by : Celine. © 2020 Houghton Mifflin Harcourt. As mentioned before, growth is the increase in size and number. Minerals and Other Nutrients – Organisms require various minerals and nutrients to support their biochemical processes and metabolism. The figure below shows the position of root apical meristem, vascular cambium and shoot apical meristem. Water – water is another important element for plants. DEFINITION • GROWTH The term growth denotes a net increase in the size, or mass of the tissue. The main difference between growth and development in biology is that growth is the increase in size and mass of a particular organism over a period of time whereas development is the overall changes in the whole organism in terms of organization and function.. Growth and development in biology are two terms used in biology while describing different processes of organisms. Growth refers to an increase in the organism's/plant's body size and mass with time. – Other than light, water, and a perfect temperature, organisms need special nutrients to support their food-making process and metabolism, which ultimately boosts growth in them. 1. The processes can be anabolic or catabolic. As the vacuoles of the primary tissue cells enlarge, the stems and roots increase in girth until a maximum size (determined by the elasticity of their cell walls) is reached. (2) The development of an organism, e.g. It is largely attributed to multiplication of cells and increase in the intracellular substance. One other difference between growth and development in biology is that growth stops at the maturation while development continues throughout life. and updated on October 3, 2017, Difference Between Similar Terms and Objects, Differences Between Growth and Development in Biology, Differences Between Fraternity And Sorority, Difference Between Body cells and Gametes, Difference Between Mitosis and Binary Fission, Differences Between Growth and Development in Psychology, Difference Between Bioburden and Microbial Limit Test, Difference Between Background Extinction and Mass Extinction, Difference Between Centrosome and Centromere, Difference Between Vitamin D and Vitamin D3, Difference Between LCD and LED Televisions, Difference Between Mark Zuckerberg and Bill Gates, Difference Between Civil War and Revolution. This is the last stage. It is also accompanied by several metabolic processes taking place at the cost of energy in the bodies. Genes also affect the growth of an organism. plants reproduce through flowers. Enlargement necessitates a change in the elasticity of the cell walls together with an increase in the size and water content of the vacuole. Cite 1. Therefore, growth is only a quantitative measurement while development is both qualitative and quantitative. However, morphogenesis is the acquisition of form and structure. Furthermore, while growth is quantitative, development is both quantitative and qualitative. Hence, various cells are differentiated from complex and simple tissues that perform different functions. "Differences Between Growth and Development in Biology." Do you agree? “Development” is defined as “a process wherein a particular organism transforms itself from a lone cell into a more complicated multicellular organism.” The most important and mandatory process in the growth of any plant is the division of cells. This happens when tissues are wounded, as when branches break or leaves are damaged by insects. So, the stage at which plants begin to flower, that growth is termed as reproductive growth. What Is The Difference Between “It’s” And “Its”? Dictionary.com Unabridged In other words, growth is considered as the most fundamental attribute of any living organism. RNDr. However, when a cell is engulfed in water and shows an increase in size through expansion, this is not considered growth. And, the process in which there are significant changes in the internal and external organs, tissues, and cells of the body of an organism is known as differentiation. What is the Difference Between Giemsa Stain and... What is the Difference Between Strain and Species. bookmarked pages associated with this title. Growth may be restricted to special regions of the organism, such as Vegetative Growth: The growth of a plant before the flowering, which includes the formation and development of its roots, leaves, and stem, is termed as vegetative growth. In contrast, in indeterminate growth, the size of the organism continuously increases throughout its life. Both are two correlating processes that go side by side. “Growth” simply means “an increase in size and mass of a particular organism over a period of time” whereas, “development” is a broader subject. Growth can be explained as an irreversible continual increase in the size of a part of the body or even of a single cell. These words describe a separate set of events in an organism or plant. Mitosis is a kind of cell division that occurs during growth, and involves both qualitative and quantitative division of the cells. But in this article, we are going to talk about the differences between growth and development in the field of biology. This article includes a massive WTF. In the Biological term, there’s a minute difference between the terms growth and development.
