Answer:
The pyrenoid, a dense structure inside or beside chloroplasts of certain algae, consists largely of ribulose biphosphate carboxylase, one of the enzymes necessary in photosynthesis for carbon fixation and thus sugar formation. Starch, a storage form of glucose, is often found around pyrenoids.
Interphase. Reason: interphase is the first stage of mitosis but since mitosis is the division of the nucleus prophase is actually the first stage.
<span>Answer: There would be more cellular damage
from harmful products of the light reactions of photosynthesis.</span>
<span>Photorespiration
is a light dependent reaction that uptake molecular oxygen and release of
carbon dioxide from organic compund. Photorespiration is linked to
photosynthesis by ribulose-1,5-bisphosphate carboxylase. However, consequence of mutation in plant due to
photorespiration deficiency will result into </span>more cellular damage from harmful products of the light
reactions of photosynthesis.
Answer:
Sub-threshold
Explanation:
If the stimulus is too small to generate the action potential, it is considered as subthreshold stimulus. Subthreshold stimulus causes the opening of small number of sodium channel i.e. not enough to generate action potential because action potential is generated by complete reversal of membrane polarity. Slight depolarization is caused by subthreshold stimulus by the opening of inadequate number of sodium channel but its magnitude is not enough to reach the threshold voltage. Consequently the action potential is not generated.
The response produced by subthreshold stimulus is called as local response or local depolarization because it could not travel further. The minimum stimulus required to generate the action potential is call as threshold stimulus and stimulus greater than threshold stimulus is called as suprathreshold stimulus. It changes the frequency of generated action potential.
