It means that different cells all have a particular job in an organism
6 of 27
Give five examples of specialised cells and what they are designed for.
Sperm cell- to fertilise eggs, Ovum cell- to be fertilised, Palisade cell- for photosynthesis, Cilia cell- to stop lung damage, Root hair cell- for absorbing
7 of 27
Why do sperms need a tail?
It provides movement so it can swim and find an egg to fertilise
8 of 27
What do Cilia cells protect?
The nasal passageways and other parts of the respiratory tract

What is tissue?
When a group of similar cells come together
11 of 27
What is an organ?
A group of different tissues working together
12 of 27
What is an organ system?
Where a group of organs work together
13 of 27
Name four main organs of a plant and say what they do.
Flower- attracts insects needed to carry pollen between plants. Stem-carries water and minerals to the leaves and food around the plant. Leaves- the organs of photosynthesis, they make all the food that the plant needs. Roots- provides anchorage
