d)amoeba

e) cells

Answer 2

a. plant need to excrete excess carbon dioxide and oxygen . carbon dioxide is waste product of aerobic respiration in plant cells. Oxygen is the waste product of photosynthesis.

b. In animals main excretory products (wasteproduct) are carbon dioxide, ammonia (in ammoniotelics) , urea (in ureaotelics) ,uric acid (in uricotelics ), guanine (in Archnida ) , and creatine.

c. The products form during respiration are

1. in aerobic respiration products are form:- carbon dioxide , water, and ATP (energy ).

2.in anaerobic respiration products are form :- common products are lactic acid, lactose, hydrogen and ethanol . carbon dioxide is also commonly produced . fermentation occurs primarily in anaerobic conditions .
