COMPARE features of Unicellular,
colonial, multicellular-
organisation including Structure,
function
UNICELLULAR including: Structure and
function (large SA:vol ratio) and
examples
COLONIAL - Individual organisms that
work together for survival and can
show cell specialisation (eg: volvox
alage, coral, sponges)
MULTICELLULAR - specialised cells
for specific jobs. Increased size,
more energy efficient for more
complexity
Cell differentiation and
specialisation- Structure
matches function
MULTICELLULAR - Cell
differentiation. Shape and size
match function. Examples: red
blood cells, cardiac cells, nerve
cells. Advantages and
disadvantages of multicellular
organisms.
Stem cells-
Undifferentiated.
Function and examples.
Levels of organisation in
multicellular- Organelles,
specialised cells, tissues,
organs, systems, organisms.
ANIMALS:
Complex animals:
specialised cells, tissue,
organs, organ systems.
Systems work together
to maintain
homeostasis
