Characteristics of Life

What is the role of DNA in living organisms?

• DNA carries genetic information essential for growth, development, and reproduction.

• DNA is responsible for producing energy in cells.

• DNA helps in the digestion of food.

• DNA acts as a barrier against diseases.

Define metabolism.

• The process of breathing in and out.

• The sum of all chemical processes that occur within a living organism.

What is the difference between growing and developing?

• To grow is to get larger, while to develop is to change.

• To grow is to change, while to develop is to get larger.

• Growing and developing are the same processes.

• To grow is to become smaller, while to develop is to remain the same.

What is the function of cells in living organisms?

• Cells are the basic unit of life, performing essential functions for the organism.

• Cells are responsible for photosynthesis in plants only.

• Cells are only involved in reproduction.

• Cells serve as the building blocks for non-living structures.

What is the difference between growth and development?

• Growth refers to an increase in size, while development refers to changes in the organism's structure and function.

• Growth is a qualitative change, while development is a quantitative change.

• Growth occurs only in plants, while development occurs in animals.

• Growth is the process of aging, while development is the process of learning.

What is reproduction in living organisms?

• The process by which living organisms produce new individuals of the same kind.

• The method by which organisms obtain energy from food.

• The way in which organisms adapt to their environment over time.

• The mechanism through which organisms communicate with each other.
