General Science ( Biology)

Cells are called as the basic unit of life because all the living organisms are made up of cells and also all the functions taking place inside the body of organisms are performed by cells. Cells provide the specific conditions, for the occurrence of the metabolic reactions.

Viruses are connecting links between living and nonliving organisms. An organism is called a connecting link when it possesses characters of two different organisms.

Chemosynthetic bacteria do not need sunlight to grow because. They do not like sunlight brightness. They prepare their food without the help of light. Due to absence of chlorophyll they are incapable of manufacturing their own food.

The branch of biology that deals with relationships between organisms and their environments is called ecology.

Viruses contain either RNA or DNA as the genetic material and never both. In general, viruses that infect plants have single stranded RNA (ssRNA) while those that infect animals may have either single or double stranded RNA (ssRNA or dsRNA) or double stranded DNA (dsDNA).

In the human body, cell growth and differentiation are tightly regulated processes. This means that cells divide and specialize in a controlled manner, allowing the body to grow and function properly. However, in cancer cells, these regulatory mechanisms break down, leading to the formation of tumors.

Reproduction: A biological process that ensures the survival of a species and genetic material between generations.

The flowering plants are plants that produce flowers as their main characteristics. However, these plants move towards the light source. This movement is a type of response that is called phototropism.
