Light microscopy: observing and drawing cells

Animal cells: common structures and specialised cells

Plant cells: common structures and specialised cells

Eukaryotic and prokaryotic organisms

Common structures of prokaryotic cells

The size and scale of cells: the basics

Pupils will learn about biological molecules that are essential to life, including sugars and other carbohydrates, proteins and lipids, and the role of enzymes in catalysing the chemical reactions in which these substances are used and made.

Pupils learned that photosynthesis in producers makes glucose, a type of carbohydrate, which is used to make biomass and as a fuel for cellular respiration.

This unit covers the structure and function of sub-cellular components in eukaryotic and prokaryotic cells and explores DNA as the genetic material of organisms. It explains genetic terms, protein synthesis, and how genetic variants influence phenotypes.

Eukaryotic and prokaryotic cells

an organism that can be seen without a microscope

an organism that can only be seen with a microscope

What does the term 'multicellular organism' mean? 

they can usually be seen with the unaided eye

Which of the following is true for unicellular organisms?

Starting with the smallest, sort the organisational structure of multicellular organisms into the correct order. 

Which of the following are found in both plant and animal cells?

jelly-like substance where chemical reactions take place

contains DNA, which controls the cell activities

where energy is released through aerobic respiration 

contains cellulose, which provides strength and support to cell 

Match the following structures with their functions. 

contains sap which helps keep the cell turgid  

contains chlorophyll, which is where photosynthesis occurs  

Shown in the image is an animal cell. What is label A pointing to?

it controls what enters and leaves the cell

it contains genetic material that controls the cell

it contains enzymes that control respiration
