What does it mean that living things are composed of one or more cells?

Back

This means that all living organisms are made up of cells, which are the basic units of life. For example, humans are multicellular, while bacteria are unicellular.

How do living things respond to their environment?

Back

Living things react to changes in their surroundings. For example, plants grow towards light, and animals may flee from danger.

Front

What is homeostasis in living organisms?

Back

Homeostasis is the ability of living things to maintain a stable internal environment despite changes in external conditions. For example, humans sweat to cool down when they are hot.

Front

Why do living things need energy?

Back

Living things need energy to perform essential functions such as growth, reproduction, and maintaining homeostasis. Energy is obtained from food, sunlight, or chemical reactions.

Front

What is the process of growth in living organisms?

Back

Growth refers to the increase in size and mass of an organism. This can occur through cell division and the accumulation of new cells.

Front

What does reproduction mean in the context of living things?

Back

Reproduction is the biological process by which living organisms produce new individuals. This can be sexual or asexual.

Front

Can you give an example of a living thing maintaining homeostasis?

Back

An example is when a person shivers to generate heat when cold, helping to maintain a stable body temperature.

Front

What is the significance of cells in living organisms?

Back

Cells are the fundamental building blocks of life. They carry out essential functions and processes necessary for the survival of the organism.

Front

How do living things grow and reproduce?

Back

Living things grow by increasing the number of cells through cell division, and they reproduce by creating new organisms, either sexually or asexually.
