Cells (temperance)
Animal and plant cells
nucleus
Contains DNA
Controls cell activities
Cell membrane
boundry between outside and cytoplasm
Acts as filter
Only lets some substances pass through
Contols substances in and out of the cell
Vacuole
Gel-like fluid, mainly water
where most chemical reactions take place
Cytoplasm
membrane bound bubble (many)
store dissolved nutrients
and mineral salts.
Chloroplasts
Surrounded by
double membrane
Contain chlorophyll to
absorb light energy
Cell wall
Permeable
Made of cellulose
Gives plant cells a regular
shape
Protects plant cells from
injury
Animal cell
No cell wall+chloroplasts
Plant cell
Division of labour
each type of cell that specialises in performing one particular function.
Eg, in animals and plants
Muscle cell and root cell
Blood and palisade
Tissue
Organs
Heart and leaf
Organ system
Digestive system and shoot system
Organism

Cells: basic unit of life
Tissues: group of cells working together to perform a function
Organs: group of tissues working together
Organ systems: group of organs working together
Organism: group of organ systems working together
Cell specialisation
Not every cell in multicellular organism performs the same task.
In multicellular organisms, cells are modifiedto carry out specialised functions
Red blood cell
Has haemoglobin to carry oxygen more effeciently
No nucleus in order to contain
more haemoglobin
Biconcave shape to increase
surface area for faster oxygen diffusion
Muscle fibre
Has fibres which involve in muscle
contraction
Nerve cell
Has a long fibre to transmit
electrical signals from one part of
the body to another quickly
In animals
In plants
Root hair cell
Has an elongated structure to
increase the surface area
Palisade/leaf cell
Contains many chloroplasts to
carry out photosynthesis faster
