Question

Plants that persists for many growing seasons is called as
A. Annual
B. Biennial
C. Perennial
D. None of the above

Answer 1

Hint: Plants are highly versatile and adaptive organisms. They can reproduce both sexually and asexually. But their growth is dependent on seasonal factors. The seasonal factors like a light period, temperature, humidity, wind currents, night periods, etc affect the plant growth majorly. Also, these factors have major impacts on the reproduction cycles of plants. Every plant has a seasonal cycle. Some plants grow for one year or annually and some grow for two years or bi-annually whereas there are plants that grow forever.

Complete answer:
There are mainly three different types of seasonal cycles among plants. Seasonal growth cycles are affected by the amount of water, temperature, and sunlight. Plans are dependent on these factors differently. Seasonal growth cycles are determined by the habitats of plants, their reproduction, and the roles they play in the ecosystem. There are three types of plants on the basis of flowering.
1. Annual: The annual plants are those that need to be replenished by new plants after a year. They grow for one year and then need to be replaced. Many garden plants are annual. Their life cycle occurs within the period of one growing season. Seeds are produced to continue the generations for the next year when suitable conditions arrive. Ephemeral (quick fading) plants are annual plants. So the annual plants do not persist for many growing seasons.
2. Biennial: Biennial means an event occurring for two years. Thus, the biennial plants complete their life cycle within two years. For the first year, they remain vegetative. During the second year, the stem elongates and flowers produce seeds. For example, carrots, parsley, etc.
3. Perennial: The term Perennial means through the year. Thus, plants that grow and live more than two years are called perennial plants. These are usually small flowering plants. They grow and bloom every spring and summer and then die back every autumn and winter. Again they return to life with the arrival of spring. For example, Apple, Dahlia, Mint, etc are perennial plants. Thus, perennial plants are the ones that persist for many growing seasons.

Hence, the correct option is Option C.

Note: The perennial plants can grow for many consecutive seasons and they dominate many natural ecosystems. They can be found on land, freshwater, and some in shallow water. Moreover, the perennial plants are thrones that form the major portions of the ecosystem. they provide stable habitats to birds, insects, and other animals. Also, they provide a regular supply of goods to humans like fruits, wood, etc.
