A student made this diagram of the cell that they observed during science class. The teacher asked the student to identify the cell as plant or animal and to explain the reasoning for their conclusion. What is the correct response?
A. The cell is an animal cell because it has a cell membrane and no cell wall. Cell walls are unique to plant cells.
B. The cell is a plant cell because it has cytoplasm, which helps the plant make their own food from sunlight.
C. The cell is a plant cell because it has chloroplast, which helps the plant make its own food from sunlight.
D. The cell is an animal cell because it has chloroplast used for making useable energy.

Oxidation-reduction reactions (often called "redox" for short) are reactions that involve the transfer of electrons from one species to another. oxidation states, or oxidation numbers, allow chemists to keep track of these electron transfers. in general, one element will lose electrons (oxidation), with the result that it will increase in oxidation number, and another element will gain electrons (reduction), thereby decreasing in oxidation number. the species that is oxidized is called the reducing agent or reductant. the species that is reduced is called the oxidizing agent or oxidant. to sum up: oxidation = increase in oxidation state = loss of electrons = reducing agent reduction = decrease in oxidation state = gain of electrons = oxidizing agent part a which element is oxidized in this reaction? fe2o3+3co→2fe+3co2 enter the elemental symbol. view available hint(s) is oxidized part b which element is reduced in this reaction? 2hcl+2kmno4+3h2c2o4→6co2+2mno2+2kcl+4h2o enter the elemental symbol. view available hint(s) is reduced
