Question

if mosses and ferns grow in an environment that is dry and where water is limited, wich of the two plants would be the most affected? explain your aswer

Answer 1

Answer:

Among the first plants to live on Earth were the ancestors of the mosses and ferns you see today. Both probably evolved from species of algae that lived in the sea and in fresh water. Mosses are more simple in structure than ferns. Mosses, and two closely related groups of plants known as liverworts and hornworts are descended from the first plants to spread onto the bare rock and soil of Earth. Ferns and their relatives appear later. Mosses are nonvascular plants. Nonvascular plants do not have vascular tissue. Water and nutrients simply move through the bodies cell by cell. Moss plants have adaptations for life on land. For example, each moss cell, like all plant cells, is surrounded by a thick wall that provides it with support. Moss cells also have special storage areas for water and Nutrients.

Mosses do not grow very large but they do have simple roots, stems and leaves. These adaptations help moss plants survive on land while algae survived only in water.

Answer 2

Answer:

Mosses among these two plants would be the most affected.

Explanation:

• While the vascular plants or ‘tracheophytes’ (Pteridophytes, gymnosperms and Angiosperms) developed special tissues to transport and retain water, the other main lineages of land plants, the bryophytes, retained a simple, nonvascular morphology.

• The bryophytes—mosses, hornworts, and liverworts—continually undergo a co-equilibration of their water content with the surrounding environment and rely to a great extent on intrinsic cellular mechanisms to mitigate damage due to water stress.

• Bryophytes are called amphibians of the plant kingdom because they can live in soil but are dependent on water for sexual reproduction.

• While Ferns (Pteridophytes) are the first vascular land (purely terrestrial) plants. Since the gametophytic body of ferns is adapted to such a restricted and limited habitat with a tropical and temperate dry environment and limited water regions, they won't face that much difficulty in surviving.

• Moss species, for instance, have no roots to separate water from the dirt nor do they have any vascular tissue to move water inside the plant.
• Ferns have both roots and vascular tissue and thus, can become larger than moss species, yet like the mosses, ferns require water for a generation. The sperm cells have flagella and should swim through a water film to treat the egg.
• This implies both mosses and ferns are generally confined to genuinely sodden natural surroundings like the woods understorey.

• But mosses lack non-vascular and also require water for fertilisation, they would be affected the most.
