Cells, division and transport

This lesson is designed to revise key ideas about Cell Biology along with some examples of exam questions. 

Start by drawing an animal cell and a plant cell and labelling it from memory!

Match the labels to their parts

Flagella

Cell wall

Cell membrane

Cytoplasm

Capsule

Free DNA

Plasmid

Match the parts of a cell to their function

nucleus

ribosomes

cell membrane

mitochondria

chloroplasts

cytoplasm

cell wall

vacuole

- makes new proteins and cell parts

Mitosis followed by separation of the cells 

DNA Replication

Preparing for mitosis

Cell grows making new proteins and more cell parts 

Put the following in order of size

Find the change in mass or length

Find the percentage change

Plot the data onto a graph

Draw a line of best fit

Read the graph to find where the line crosses the x axis to find the concentration

Complete the table

Draw a graph and work out the solute concentration in the potato
