A unicellular organism is a living thing that is just one cell.

Multicellular organisms are made of lots of different types of cells.

A tissue is a group of similar cells in the same place with the same job.

An organ is made up of a group of different tissues that work together to carry out a specific job.

An adaptation is a feature that helps an organism to function and survive.

Multicellular and unicellular organisms

Science

Pupils will learn about bones and muscles as examples of tissues made of cells.

In Y2 of primary science, pupils learned about some processes that happen in all living things (and do not happen in things that are dead or have never been alive).

Cells

Choose two correct reasons that a unicellular organism is called living

An organism that is made up of lots of cells joined together is called {{}}

Starting from the smallest put these structures in size order

Smallest living unit that carries out the common processes

Similar cells, with a similar job, that work together

Different tissues that work together to carry out a job

Match the keyword to the correct definition

Choose which one of the tissues that would not appear in a stomach

All organisms, living or dead, are made up of {{}}

Which of these examples are made up of cells?

Starting with the smallest put these structures in order of size

Cells are too small to view with the unaided eye, a {{}} is used to magnify them.

Changing location itself to achieve something for survival

Using food and other nutrients to stay alive

Taking information from and responding to surroundings

Match these common processes of cells to the correct definition

Choose two techniques that should not be used in a scientific line drawing of a cell
