What is a tissue? Why do many-celled living things need tissues, when a one-celled living thing does not?
Need a reminder? The key ideaShow
A tissue is a group of similar cells that work together to do one job.
The worked solution
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, compare your working with the solution.
Step 1. A tissue. A group of cells that are alike in structure and work together to do one job.
Step 2. Why. In an amoeba, one cell does everything. In a many-celled body, groups of cells take on different jobs, such as carrying water or making the body move. This division of labour lets each job be done well.
