Plants store their waste products in a vacuole. the waste products are recycles back into the ground in the fall when the leaves fall off. which of the following make up the waste products that plants get rid of?
a. oxygen and urine
b. carbon dioxide and urine
c. carbon dioxide, oxygen and ions

Ans. (C). carbon dioxide, oxygen and ions.

Plant cells have membrane-bound vacuoles to store waste products formed in the plants. These waste products include carbon dioxide, oxygen, and some ions. Carbon dioxide is formed as byproduct of cellular respiration, oxygen is formed as byproduct of photosynthesis, and some inorganic ions are formed from different cellular reactions. Urine is not formed in the plants.

Thus, the correct answer is option (C).

answer:

sequence 1- deletion

                  2- duplication

                  3- insertion

                  4- substitute

                  5- inversion

the answers are a and c
