Answer:
Ferns are not the only plants to reproduce from spores. Mosses, liverworts and green algae also have spores.
Cutting – In this, a portion of a plant is cut and planted in the soil, usually a stem or a leaf. ... Grafting – In this, the cutting from some other plant is added to the plant stem embedded in the soil. ... Layering – In this, the stem of the plant is bent to the ground and covered with soil.
When a flower has both the essential whorls i.e., androeclum and gynoeclum (male and female reproductive units) including stamens, carpels and an ovary, it is called a bisexual flower.
