Answer:
Plant cell
Explanation:
Cell wall: cell wall is only found in plant cell . it is made up of cellulose. it's function is to give shape to the cell and protect the delicate inner parts of the cell. this cell is fully permeable. it means it will allow all substance to pass in. cell membrane is made up of protein and lipids. it's function is to control what comes in and out of the cell. this membrane is selectively permeable. it means it allows some substance to pass in and others don't. cytoplasm is large sac like structure. most chemical process occur here. chromoplast are the green pigments.
cell wall is only found in plant cell . it is absent In animal cell . the neucleus in the plant cell contain a pigments haemoglobin, which contain genetic information to the cell .
I don't think changing seasons can REMOVE CO2 from the air, but I do think instead it could add it to the air. It's a long process that involves several ecosystems and stuff. But, as the climate is getting warmer, ice caps are melting and within these ice caps... there are trapped bubbles of CO2 that are released ( I am not sure if this adds a lot of CO2 to the atmosphere, but I am sure that it does contribute to CO2 concentration).
In relation to your last statement... plant growth would actually reduce CO2 in the air because of the process of photosynthesis. Plants take in CO2 and give out O2 for us to breathe. In turn we conduct cellular respiration in which we take in the O2 and give out the CO2. So, plants are actually one good solution for decreasing CO2 levels.
