Question
1. Explain how members of the Chlorophyta appear more closely related to members of the plant kingdom than other photosynthetic protists do.2. Explain how water moves through a plant (e.g., what causes it to move from the plant to the air, and from the soil to the plant, etc.). Contrast this with the way in which water moves in the phloem. Explain how the structure of the conducting cells in xylem and phloem differ, and how these differences relate to the forces that move fluid through these different types of cells.
please be specific.
Explanation / Answer
1. Chlorophyta are closely related to plant kingdom, becuase chlorophytes are the first cells to synthesize the pigments chlorophyll a and b, that are found in all photosynthetic plants. Due to this chlorophyta, are sometimes grouped under kingdom plantae.
2. Movement of water in the plant, occurs through roots, from soil to atmosphere.
At first water passes from the soil into the root hair. Water inside the cells in the root has much higher solute concentrations than does water in the soil so there is a water potential gradient. Hence water moves into cell through osmosis.
The water moves across the root from the hair cell to the xylem by apoplast, symplast or vacular pathway.
