Question

What characters of seed plants make them specially adapted to life on land?

Answer 1

List of four features that all seed plants have in common. Roots, stems, leaves, vascular tissue, and seeds are all present in seed plants.Plants have evolved embryo retention, a cuticle, stomata, and vascular tissue as adaptations to living on land.

Complete answer:
The presence of a broad root system for anchorage and absorption, as well as the development of mechanical tissues for support and vascular tissue for long-distance transfer of sap and food, are all characteristics of seed plants that make them uniquely adapted to life on land.
The development of pollination, or the transfer of microspores to megasporophylls, as well as the replacement of external water for fertilisation by the production of a pollen tube for transport sperm to female gametes. Transformation of megasporangium and production of embryos in the ovule.
To withstand arid circumstances, spores have developed protective walls. Water loss across cell walls is reduced by a waxy cuticle. The creation of a vascular system in order to access water from deep within the earth. Stomata are pores that can open and close in the cuticles of leaves. For rigid support, specialised cells with thickened cell walls are used.

Note:-
Plants were able to reduce their reliance on water for reproduction thanks to the evolution of seeds. Seeds contain a latent embryo that will grow into a diploid sporophyte when the conditions are right. To stimulate reproduction and limit competition with the parent plant, seeds are transferred by the wind, water, or animals.
