Answer:
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product.
I believe it is either B or A, personally i'm leaning towards B, but at the same time, i don't think that we would be obtaining materials via pollination, so it then causes A to make more sense.
A plant was placed in water containing black dye. After 24 hours the
plant was removed and sections were taken from the root and the
stem. In the root, cambium part will get stained and in the stem, cortex will be stained from dye so the correct option is D.
<h3>
What is cambium and cortex in plant root and stem?</h3>
Cambium is a layer of continuous dividing cells between xylem and phloem tissues which is responsible for the secondary growth of stems and roots. A cortex is an outer layer of a root or stem in a plant, located below the epidermis but outside of the vascular bundles.
The conduction (uptake) of water in a plant stem takes place through the xylem.

Answer:
d.) All of the above
Explanation:
Prophase is the first stage of mitosis. In this phase, the DNA condenses into chromosomes. The nuclear membrane breaks down, and the centrioles move to opposite sides of the cell.
The next phase is metaphase, where the condensed chromosomes move to the centre of the cell.
Next, during anaphase, the chromosomes are separated to either end of the cell
Finally, during telophase and cytokinesis, the nuclear membrane reforms and the chromosomes begin to decondense, and the cytoplasm splits to form two cells.
Binding blocks the electron transport system in the mitochondria where ATPmanufacture occurs (Goodsell, 1996, p.74). Energy is usually liberated from the ATP molecule to do work in the cell by a reaction that removes one of the phosphate-oxygen groups, leaving adenosine diphosphate
