The diagram illustrates photosynthesis. which best describes what is happening in the area marked x? 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.

The correct answer is water is carried to the leaves by xylem.

Explanation:

Xylem and Phloem together form a vascular tissue of plants.

Xylem transfers water and minerals from roots to every part of the plant with the help of stem. It is uni-directional.

Phloem transfers food from leaves to every part of the plant whenever in need. Phloem uses energy in the form of ATP in both the directions. It is multi-directional.

Hence, the correct answer is water is carried to the leaves by xylem.

b..

is the correct one

explanation:

covalent bonds form as valence electrons are shared between two atoms. lewis structures and structural formulas are common ways of showing the covalent bonding in organic molecules. formal charge describes the changes in the number of valence electrons as an atom becomes bonded into a molecule.
