B2 REVISION – CHAPTER 1 – CELLS
What do plant cells have that animal
cells do not?
Sketch and label a plant and an animal
cell;
Use pictures and words to describe how substances can move
in and out of cells by diffusion
What is the function of:
Nucleus –
Mitochondria
Ribosome
Chloroplasts
Cell Wall
Label the yeast and bacteria and write 4 bullet points about
the characteristics of each one
Draw and label 2 specialised cells. Explain their structure is adapted to suit their
function
KEY WORDS:
Describe the difference
between aerobic and
anaerobic respiration in yeast
B2 REVISION – CHAPTER 1 – Cell, Tissues & Organs
Bacteria & Yeast
Animal & Plant Cells
Structure
Purpose
Plant/Animal/Both
Controls the cells
activities
Cytoplasm
Both
Where is the genetic material in a bacteria cell?
How many cells make up yeast?
Mitochondria
Specialised Cells
Cells are
specialised to
carry out a specific
function. The
structure gives a
clue to its function.
Diffusion
Ribosomes
Is how dissolved
substances and
gasses move into
and out of cells.
Protein synthesis
takes place
Plant
Contain
chlorophyll, absorb
light energy to
make food
Vacuole
If a cell has many ribosomes it is making a lot
of protein, which type of cell might it be?
KEY WORDS:
Gland cells
Nucleus
Algal cell
Cellulose
Chloroplast

Tissue
Function
Glandular
Animal/Plant
What is an organ?
What are the main organs of a plant?
Label the image below and explain the function of each
tissue
Epithelial
What is an organ system?
Epidermal
The digestive system’s function is
Mesophyll
Label the diagram> For each organ
describe the function it performs
Xylem
phloem
Adaptations for exchange – For each one of the organs
below write down the substance that is exchanged
•Lungs:
•Small intestine:
•Kidneys
