In what order are the following thought to have evolved to have given rise to
complex multicellularity?
Give this one a try later!
1) Cell Division
2) Cell Adhesion
3) Cell Communication
4) Diversification and Regulatory Genes
Endosymbiosis
Give this one a try later!
, Involves one cell engulfing another to produce, over time, a co-evolved
relationship in which neither cell could survive alone.
What features would you expect SIMPLE multicellular organisms to have in common?
Give this one a try later!
- A means by which to hold cells together.
- Each cell retains a full range of functions.
- Nearly every cell is in contact with the external solution.
Diffusion
Give this one a try later!
The random motion of molecules, with net movement from areas of higher
to lower concentration.
What are some advantages of being multicellular?
Give this one a try later!
- It can provide protection against predation.
- It can provide stability and help anchor the organism.
- It can increase the ability to acquire food/nutrients
