Explanation:
The sclerenchyma is the tissue in which creates the plant firm and hard. The two kinds of sclerenchyma cells exist fibers and sclereids. Their cell walls be made up of cellulose, hemicellulose and lignin. The sclerenchyma cells are the principal associate cells in plant tissues that have come to a close elongation.
Answer:
The correct answer is C in presence of oxygen production of acetyl CoA,TCA cycle and electron transport chain occur in a proper order.Whether in absence of oxygen lactic acid fermentation or alcoholic fermentation occurs.
Explanation:
Aerobic respiration occur in presence of oxygen which involves glycolysis,TCA cycle and electron transport chain.Aerobic respiration result in the catabolism of glucose to generate CO2,H2O and ATP.
But in absence of oxygen or during anaerobic condition pyruvic acid is converted to either lactic acid by pyruvate dehydrogenase or to ethanol through alcoholic fermentation.
