Solution
Hint A perennial plant, sometimes known as a two-year plant, is one that lives for more than two years. The phrase is frequently used to distinguish a plant from annuals and biennials, which have shorter lives. Plants with little or no woody development are often referred to as perennials, as are trees and shrubs, which are also officially perennials.
Complete step by step answer:
Herbaceous perennials are perennials, particularly small flowering plants, that develop and bloom in the spring and summer, fall back in the autumn and winter, and then reappear in the spring from their rootstock or other overwintering structure.
A plant that is a perennial in its native habitat, or in a warmer garden, may be handled as an annual by a gardener and planted out every year, from seed, cuttings, or divisions, depending on the rigours of local climate temperature, moisture, organic content in the soil, and microbes.
Tomato vines, for example, can thrive for several years in their original tropical/subtropical habitat but must be cultivated as annuals in temperate climates since their above-ground biomass does not survive the winter.
One of the most distinguishing features of gymnosperms is that they are all perennial and woody plants.
Angiosperms, or blooming plants, reproduce by use of developed ovaries, or fruits, whereas gymnosperms, or vascular plants, reproduce by means of an exposed seed, or ovule. Many gymnosperm seeds or naked seeds are carried in cones and are not visible until they reach maturity.
So the correct answer is option C.
Note: Perennial crops provide a lot of advantages. Perennial plants have deep, widespread root systems that can hold soil in place to avoid erosion, collect dissolved nitrogen before it contaminates ground and surface water, and out-compete weeds, minimising the need for herbicides.
