Two especially important characteristics of plant cells are _ _ _ _w_ _ _ _ and _ _a_ _ _ _ _.

Cell wall and plastid

Explanation:

The most important difference between plant cell and animal cell is that  plant cell contain cell wall for mechanical strength and plastid to carry out photosynthesis(chloroplast). and storage(leuko plast).

    But in case of animal cell cyto skeleton is present in place of cell wall and plastid is absent because animals generally does not carry out photosynthesis.

answer: after carbon dioxide enters the leaf through stomata it moves into the mesophyll cells where photosynthesis occurs and glucose is constructed. respiration occurs when glucose (sugar produced during photosynthesis) combines with oxygen to produce useable cellular energy.
