The length of time a plant can live depends on the species. There are three classifications for the length of a plant's life span: annuals live one growing season, biennials live two growing seasons and perennials live more than two growing seasons.Know More
An annual plant species completes its life in one year or less, meaning that it germinates, or begins growing; produces vegetative growth such as leaves and stems; flowers; sets seed; and dies in one year. Examples of annual species include lettuce and marigolds.
A biennial species completes its life cycle in two years, or seasons. During the first season, the plant is only vegetative, which means it has leaves and stems. During the second season, it produces flowers, sets seed and dies. Examples of biennial species are carrots and onions.
A perennial species completes its life cycle over many years. It may not flower or set seed for several years while it is growing in the vegetative stage, but once mature, it produces flowers and sets seed many times over the course of its lifetime. Examples of perennial species include woody plants such as trees. Some of the oldest trees have been known to live about 5,000 years.Learn more in Botany
The main distinguishing feature of the pellicle is that it lacks cellulose and, in some species, is flexible enough for self-propelled motion of the cell. The analogous structure in plants, by contrast, is much stiffer, contains cellulose and is incapable of motion.Full Answer >
Tall and short varieties of grass and some flowering perennials dominate grasslands, including the prairies of North America. Big bluestem grass, blue grama grass, buffalo grass and Indian grass are abundant. Flowering perennials like milkweeds, goldenrods, asters, blazing star, sweet coneflower and purple coneflower bloom where rainfall is sufficient. These plants survive cold winters and fires in grasslands by developing underground storage organs and thick stem bases.Full Answer >
