McInnes Year 7 Stayin' Alive Cells Recap

Cells are found in

• living things ONLY

• non-living things ONLY

• BOTH living and non-living things

Which statement is NOT part of Cell Theory?

• All organisms are made of cells.

• All living things are made of multiple cells that are specialised.

• All existing cells are produced by other living cells.

• The cell is the most basic unit of life.

Match the following:

• unicellular organism

• Made of a single cell

• muti-cellular organism

• Made of multiple cells

• non-living

• Made of zero cells

Within ​ (a)   organisms, different cells are built differently because they have ​ (b)   roles. This is known as cell ​ (c)   .​

• multicellular
• specialised
• differentiation
• unicellular
• singular
• similarity

Organise these examples into the right categories:

Groups:

(a) Unicellular organisms

,

(b) Multi-cellular organisms

• protists

• amoeba

• trees

• mushrooms

• humans

• bacteria

• yeast

• birds

Cells come from pre-existing cells by a process called cell

Identify the function of each organelle

• Control centre; contains DNA

• Nucleus

• Storage of water and chemicals

• Membrane

• Controls movement in and out of cell

• Mitochondrion

• Powerhouse (coverts food to energy)

• Vacuole

• Makes food for plants; photosynthesis

• Chloroplast
