1
Q
what did the study show between the algal symbiont and the protist?
A
photosynthetic symbiosis based on exploitation of symbionts by the host- not mutualism
2
Q
with increasing light who benefits and how?
A
protozoa paramecium hosts as symbiosis is more beneficial
3
Q
with increasing light who is it costly for?
A
chlorella algal symbionts
4
Q
does the fitness of the 2 align and what does this mean for the cost of symbiosis?
A
no
always costly for the algae
5
Q
what can the hosts manipulate?
A
symbiont load according to light intensity
6
Q
what does the host provide to the endosymbionts and in return for what?
A
N
maltose and O2
7
Q
when is the symbiosis costly for the host?
A
if the endosymbiont is in the dark
