Answer:
Plants get carbon dioxide from the air through their leaves. The carbon dioxide diffuses through small holes in the underside of the leaf called the stomata. The lower part of the leaf has loose-fitting cells, to allow carbon dioxide to reach the other cells in the leaf.

Explanation:
B) After determining the optimum pH, they could vary the temperature of the environment to see if catalase is temperature specific
Enzymes are proteins which catalyze reactions by acting on substrates in order to speed up reactions- like the breakdown of large polysaccharides by amylase. Here, the enzyme catalase facilitates the breakdown of hydrogen peroxide into oxygen and hydrogen. Catalase specificity is affected by pH, temperature and the presence of inhibitors.
In temperatures beyond its optimal range, catalase may undergo changes to its physical structure called denaturation; when denatured, enzymes lose their ability to bind specifically to their substrate -i.e. substrate binding specificity is lost. H2O2 would no longer be able to bind to the active site, and thus would not be broken down.

I assume you are not familiar with this topic. I suggest you read more about this protein from online books or ur own book if you have.
White blood cell = its a cell just like the name suggests, in fact, more like its a family of cell types that are responsible for immunity and some other functions (it doesnt look like you need to know the details on other functions so just stick with immunity)
Platelets = these are not really cells, but you can say they are sorta like bits of cells, they contain important protein(s) for blood clotting and surely they themselves play important role in blood clotting which prevents us from bleeding to death when we get a cut for example.
Plasma = this is part of blood, excluding red blood cells and white blood cells, its basically fluid with nutrients, ions and most importantly blood proteins, such as carrier ones like Albumin.
The only one left is Hemoglobin,
heme is the iron part (which is not really iron alone but thats the only one u need to know)
and globin is the protein part
these two make up hemoglobin
so this complex resides inside red blood cells, which flow in our vessels to every part of our body supplying them with nutrients and oxygen taken from our capillary system of lungs.
