What are xeromorphic leaves?
Plants with xeromorphic leaves (xerophytes) are adapted to a dry atmosphere. They are designed to prevent water loss. Like in the leaves of monocots (belonging to the angiosperms – anthophyta or flowering plants) the stomata are arranged in long arrays in pine needles.
What is xeromorphic adaptation?
Plants with such morphological and physiological adaptations are xeromorphic. Xerophytes such as cacti are capable of withstanding extended periods of dry conditions as they have deep-spreading roots and capacity to store water. Their waxy, thorny leaves prevent loss of moisture.
What are the leaves of gymnosperms?
Gymnosperm Leaves are generally tough, scaly, or needle-like. They have a thick and waxy cuticle, sunken stomata and vascular tissue (xylem and phloem). Gymnosperms are a group of seed-bearing plants that do not form fruits.
What are the characteristic features of gymnosperms?

- Seeds are not formed inside a fruit.

What are Mesophytic plants?
From Wikipedia, the free encyclopedia. Mesophytes are terrestrial plants which are neither adapted to particularly dry nor particularly wet environments. An example of a mesophytic habitat would be a rural temperate meadow, which might contain goldenrod, clover, oxeye daisy, and Rosa multiflora.
What is gymnosperm plants?
gymnosperm, any vascular plant that reproduces by means of an exposed seed, or ovule—unlike angiosperms, or flowering plants, whose seeds are enclosed by mature ovaries, or fruits. The seeds of many gymnosperms (literally “naked seeds”) are borne in cones and are not visible until maturity.
Do gymnosperms have leaves?
Most gymnosperms are evergreen, but some, such as larch and bald cypress, are deciduous (the leaves fall after one growing season). The leaves of many gymnosperms have a thick cuticle and stomata below the leaf surface.
