Question

Important terrestrial adaptations that evolved exclusively in seed plants include all of the following except ​

Answer 1

Terrestrial adaptations of seed plants

Explanation:

• Plants are utilised to make food, clothing, medications, construction materials, and a variety of other essential human products.
• Whenever the conditions are correct, seeds contain a dormant embryo that will develop into a diploid sporophyte. Seeds are dispersed by wind, water, or animals in order to promote reproduction and prevent competition with the parent plant.
• A tropical shoreline's lush palm trees don't need water for pollen dispersal, fertilisation, or zygote survival like mosses and liverworts.
• Palms and other seed plants have broken free from their reliance on water for reproduction. They are involved in every element of life on the planet, changing the physical landscape, impacting the climate, and ensuring that life as we know it continues.
• Human communities have relied on seed plants for millennia for nourishment and medicinal ingredients, as well as industrial by-products including timber and paper, dyes, and textiles. Rattans, oils, and other commodities are provided by palm trees.
• Seeds include a diploid embryo that will germinate into a sporophyte, unlike bryophyte and fern spores (which are haploid cells required on moisture for rapid development of gametophytes).
• Seeds have a higher evolutionary advantage because they have storage tissue to maintain growth and a protective coat.
• Desiccation is prevented by several layers of hardened tissue, which frees reproduction from the requirement for a steady supply of water.
• Furthermore, seeds remain dormant until the conditions for growth become suitable, which is produced by desiccation and the hormone abscisic acid.
• Seeds are dispersed in a widening geographic area, whether blown by the wind, floating on water, or carried away by animals.
