Lack of water triggers thirst.

The lack of water in the external environment creates an urge to drink water. The mind sends the signal that there is a loss of water from the body and it is dehydrated. This signals is recognized by the body and water is taken after this signal. The human body is made up of 70% of water and is vital for performing various functions of the body. Dehydration of water can led to several problems. The human body should not wait for the signal associated to dehydration and 4-5 liters of water must be taken daily.

How are vascular and non-vascular plants different, and how do each of them work through osmosis?
Lilit [14]

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.
