Answer:
Explanation:
Vascular plants have tubelike structures that carry water, nutrients, and other substances throughout the plant. Nonvascular plants do not have these tubelike structures and use other ways to move water and substances.
Vascular plants are said to have a true stem, leaves, and roots due to the presence of vascular tissues. Non-vascular plants do not have true roots, stems, or leaves and the tissues present are the least specialized forms of tissue. Some examples of vascular plants include maize, mustard, rose, cycad, ferns, clubmosses, grasses. Some examples of non-vascular plants include moss, algae, liverwort, and hornwort.
How vascular plants work through osmosis
The xylem of vascular plants consists of dead cells placed end to end that form tunnels through which water and minerals move upward from the roots to the rest of the plant. Through the xylem vessels, water enters and leaves cells through osmosis.
How non vascular plants work through osmosis
Because non vascular plants do not have the xylem and phloem ystem, they absorb water right into their cells through their leaves when it rains or when dew falls. Internal cells get their water by passive osmosis. While, they use rhizoids to transport nutrients and minerals.
Answer:
False
Explanation:
A double-helical DNA molecule consists of two DNA strands. A DNA strand has free 5' phosphate at one end and a free hydroxyl group (OH) at its 3' end. A DNA double helix is said to be antiparallel since each end of the double helix has an exposed 5' phosphate on one strand and a free 3' hydroxyl group (OH) on the other. This means that the two DNA strands run in opposite directions. A phosphate group is always esterified to the 5' carbon of the pentose sugar; never at its 3' end.
