1
Q
why is there a need for a communication system in multicellular organisms?
A
they are needed to coordinate the specific functions of different cells and systems to operate effectively
2
Q
which systems carry out cell signalling?
A
nervous system
hormonal system
3
Q
how do cells undergo cell signalling?
A
- transfer signals locally between neurones at synaposes
NEURONAL - transfer signals across long distances using hormones
HORMONAL
4
Q
do plants have a nervous system?
A
NO
