Which of the following characteristics of plants is absent in their closest relatives, the charophyte algae?
a. chlorophyll b
b. cellulose in cell walls
c. sexual reproduction
d. alternation of multicellular generations

d. alternation of multicellular generations

Explanation:

The gametophytic as well as the sporophytic generations are alternative in the life cycle of the multicellular plants. This can be seen among the land plants. This feature cannot be seen in the algal species as they are unicellular in nature. Thus cannot be seen in the relatives of charophyta algae.

when a reversible reaction is occurring in both directions at the same rate; the products and reactants do not change in concentration. a chemical reaction where the compound is broken into its constituent parts.

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.
