Growth in Living Organisms

Growth is the process of increasing in physical size and mass. This is a fundamental characteristic of all living organisms and is essential for the survival and development of the organism.

Types of Growth

1. Cellular Growth: This involves an increase in the number and size of cells. Cells divide and multiply, leading to the growth of tissues and organs.

2. Individual Growth: This refers to the overall increase in size and mass of an organism as it progresses through its life cycle.

Factors Affecting Growth

1. Genetic Factors: The genetic makeup of an organism influences its growth potential. Different organisms have different growth rates and patterns based on their genetic information.

2. Nutritional Factors: Adequate nutrition is essential for healthy growth. Nutrients such as proteins, carbohydrates, fats, vitamins, and minerals play a crucial role in supporting growth and development.

3. Environmental Factors: Environmental conditions such as temperature, light, water, and air quality can impact the growth of living organisms. For example, plants may grow differently in different climates and soil conditions.
