Quiz: Compare and contract ips and embryonic stem cells
Ans: They both
-have the potentiation to divide indefinitely (no hayflick limit)
-they can specialize into different cell types
Difference
-ips is adult cells however embryonic is taken from the inner cell mass/morula
-less ethical issue using ips
-no rejection for ips
-iPS cells can form adult cells whereas embryonic cells form younger cells (1)

, Ans: organ has {many / eq} functions, tissue has {one / fewer / eq},
both have cells {working together / for the same function / eq} ;
Quiz: What are some adaptations of an egg cell
Ans: - haploid so can form a full 46 chromosomes during ferrtilisation
- lipid droplets for suplling energy for division
- large cell so this increases change for fertilization
- zona pellucida prevents polyspermy
- cortical granules
- so zona pellucid hardens
- mitochondria provide energy
