Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which is true of bryophytes (non-vascular plants)
A
They have tissues that conduct water
B
They draw up water by osmosis
C
They are not highly dependent upon water
D
Algae and mosses are in this catagory
Explanation: 

Detailed explanation-1: -This statement is false. Mosses are part of the bryophyte taxon, which includes other non-vascular plants such as liverworts. These plants do not have any vascular tissues like xylem or phloem. Mosses will transport water and solutes through osmosis and diffusion.

Detailed explanation-2: -Bryophytes have life cycles that depend on water for reproduction. Bryophytes draw up water by osmosis only a few centimeters above the ground. During one stage of their life cycle, bryophytes produce sperm that swim through water to reach eggs of other individuals.

Detailed explanation-3: -Mosses and liverworts are small, primitive, non-vascular plants. They lack the conductive tissue most plants use to transport water and nutrients. Instead, moisture is absorbed directly into cells by osmosis.

Detailed explanation-4: -In plants, osmosis means water molecules moving from cells that have lots of water to cells that have less water.

Detailed explanation-5: -Non vascular plants reproduce with sports rather than seeds. Non vascular plants have extensive vascular tissue. Non vascular plants only produce large in the gamma divide stage. So option B is correct over here, enormous for the plants reproduce with spores rather than seeds.
