Answer:

1)so opening and closing of stomata is done by guard cells.. as per the concentration of water the stomata opens or closes

2) aerobic- with oxygen, more energy eg humans

anaerobic- without oxygen, less energy, eg yeast

Answer:

1) opening and closing of cell is regulated by guard cell, in presence of water or absence of water in stomatal pore , if stomatal pore connist of water it swell then guard cell open , and when there is no water it get shrink , which lead to closing of guard cell

2) aerobic

Respiration take place in presence of oxygen

compelet breakdown of gulcuose take place

it take place in mitochondria

anerobic:-

respiration take place in absence of oxygen

incompelet breakdown of gulcouse take place

it occur either in muscle cell of animal or in yeast
