For starters, plant cells have a tough Cell Wall made from cellulose, while animal cells only have the thin Cell Membrane. Also, plant cells have Plastids, while animal cells do not.
The primary organelle which is present in plant cells but not in animal cells, however, are the Chloroplasts, which allow plant cells to carry on the natural process of photosynthesis, by which plants make their own food using sunlight, water, and nutrients from the soil.
Hope that helped =)
1) The first reactant is incomplete.
2) The reaction is a combustion reaction and it is easy to infere that it is the combustion of the alkane with 3 carbons.
3) The general chemical formula of the alkanes is

4) Hence the equation is:

5) The name of the alkane is propane, so the word equation is:
propane + oxygen → carbon dioxide + water
6) The equation is unbalanced. This is the balanced equation:

7) It is, as the combustion of any hydrocarbon, a redox (reduction-oxidation) reaction, where the carbon is oxidized and the oxygen is reduced.
8) This kind of reactions release a lot of energy.
Answer:
Sunlight
Explanation:
The correct answer is sunlight. Plants compete for all the listed things. However, in contrast to most animals, they strongly compete for sunlight.
i hope this helps !! hope you can make this a brainliest.
