Welcome everybody to the new topic "LIVING THINGS"


In nature there are non-living things, such as rocks and minerals, and living things such as animals and plants.

All living things depend on life processes to stay alive, and the processes are: nutrition, sensitivity and reproduction.

  • Nutrition provides two things: substances that living things need to grow and energy to carry out life processes.
  • Sensitivity enables living things to react to what they perceive around them.
  • Reproduction enables living things to create offspring similar to themselves.
All living things are made up of tiny units which are called cells. Cells are the smallest living units in a living thing.
Some living things are made up of a single cell, which are called unicellular

However, other living things are made up of many cells, which are called multicellular.
Cells differ in shape and size, and they carry out different tasks.
Which are the main parts of a cell? Now you have to search it on the internet.

Multicellular living things have the following structure:

- Cells form tissues. Tissues, such as mucle tissue, are made up of cells which work together.

- Tissues forms organs. Organs, such as the heart, are made up of tissues which work together.

- Organs forms systems. Systems, such as the digestive system, are made up of organs which work together.

- An organism is a complete living thing. Many systems work together in an organism.
