23.

Alcohol fermentation

a)

Is the process of using yeasts to convert sugars into alcohol.

b)

Breaks down sugars to produce energy in the form of ATP.

It occurs in the absence of oxygen.

24.

Lactic acid fermentation

a)

Breaks down sugars to produce energy in the form of ATP.

It occurs in the absence of oxygen.

b)

Is the process of using yeasts to convert sugars into alcohol.

Its purpose is to produce ATP that can be used as an energy source in various processes taking place in the cell.

25.

How many guard cells surround the stomata

1,2,3,4,5,6,7,

(a)  

26.

When the plant is well hydrated

a)

the guard cells are swollen with water and bow outward opening the stomata.

Carbon dioxide passes into the leaf and some of it is used up during the carbon fixation part of photosynthesis.

Water and oxygen that is a by-product of photosynthesis leave the leaf.

b)

water leaves the guard cells and they collapse closing the stomata.

With the stomata in the leaf closed the concentration of carbon dioxide in the leaf goes down.

and the concentration of oxygen goes up as photosynthesis proceeds.

The increased concentration of oxygen eventually shuts down photosynthesis because of the phenomenon called photorespiration.
