NEET BIOLOGY

Detailed explanation-1: -Some plants, like ferns and mosses, grow from spores. Other plants use asexual vegetative reproduction and grow new plants from rhizomes or tubers. We can also use techniques like grafting or take cuttings to make new plants.

Detailed explanation-2: -In asexual reproduction new plants are obtained without production of seeds. It is a type of asexual reproduction in which new plants are produced from roots, stems, leaves and buds. Since reproduction is through the vegetative parts of the plant, it is known as vegetative propagation.

Detailed explanation-3: -Gymnosperm means “naked seeds". They are called this because their seeds are open to the air with no covering such as the seeds of flowering plants. One of the major groups of gymnosperm plants is the conifer. The word “conifers” means “bearing cones.” Conifers are plants that use cones to house their seeds.

Detailed explanation-4: -Non-flowering plants can reproduce by spores or seeds. Plants like mosses, liverworts, and hornworts, known as ‘Bryophytes’, reproduce by spores. Bryophytes are nonvascular plants, which means they also lack roots, stems, and leaves.
