Which of the following is a structure that is found in the seeds of angiosperms and that often functions as a food storage organ?

xylem
taproot
bryophyte
cotyledon

Cotyledon.

Explanation:

Cotyledon is a part of the seed embryo and it is defined as the embryonic leaf or first leaf that first germinate in angiosperms . It is formed within the endosperm of the seed and it serve as energy storage or source of energy to provide initial growth for the plants.

There are two types of cotyledon, monocotyledon and dicotyledon.

Monocotyledon have single cotyledon while dicotyledon have two cotyledon.

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.
