When the seed of a tree first starts to grow, what would happen if the cells did not
differentiate?
all of the cells would be identical.
the seed could form roots, but not leaves.
the dna would make new cells.
other cells would differentiate.

All of the cells would be identical.

Explanation:

Cell differentiation is necessary process for proper development of a living organism. The cells differentiate to form tissue and the group of similar tissues forms organs.

Related organs become part of organ systems and perform various functions.   If cell differentiation doesn’t take place tissue and organ formation doesn’t happen.

The cell would be completely identical. Due to the lack of cell differentiation parts like leaf, stem etc do not form.

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
