He diagram illustrates photosynthesis. Which best describes what is happening in the area marked X? X is the stem.

Carbon dioxide enters the stem through xylem.
Oxygen enters the stem through stomata.
Water is carried to the leaves by stomata.
Water is carried to the leaves by xylem.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
