2-Cells organization

All living things are made up of cells, which are the basic building blocks of life. In multicellular organisms, cells that carry out the same functions join together to make tissue. Tissue groups together to make organs such as the heart or lungs, which in turn form systems such as the circulatory system or the respiratory system. Together they form an organism.

CELLS → TISSUE → ORGANS → SYSTEMS → ORGANISM

There are 2 types of cells:

LIVING THINGS

1-Introduction

Our world is made up of living things and non-living things. Many of these living things are very small, while others are much larger than we are. However, they all share certain characteristics: they all interact with their environment, they grow, reproduce and eventually die. All living things are made up of cells . 

Living things can be classified into 5 kingdoms:

Characteristics of living things:

• Nutrition: they need food to obtain energy.
• Excretion: they produce waste.
• Reproduction: they produce new living things.
• Growth: they use energy to increase in size.
• Movement: they change position.
• Interaction: they connect with the world around them.
• Respiration: they exchange gases with the environment.
