Why is it important to know the life cycle of crops?

Because a major source of our food is from plants, we can classify them by their life cycle
. Crops can be sorted into annuals, biennials and perennials.
What are seasonal plants?

specialised annual plants which are characterised by the flowering pattern once in a year only for two or four months
. The seasonal medicinal plants are: Basil (Tulsi) Chamomile. Aloe vera.
How do plants complete their life cycle?
Plant life cycles are classified as annual, biennial, or perennial. Annuals complete their life cycle of
germination from seed, growing, flowering, fruiting and dying within a single season of growth
. Biennials require two seasons to complete their life cycle.
Which crops grown in winter season?

Why are Rabi crops grown in winter?

What is crop requirement?

. Biennials are usually sold with perennials and include sweet william, foxglove, money plant and hollyhock.
What type of plant only lives for two growing seasons?
Biennials
– Plants which require two years to complete their life cycle. First season growth results in a small rosette of leaves near the soil surface. During the second season’s growth stem elongation, flowering and seed formation occur followed by the entire plant’s death.
Do seasonal plants come back every year?

biennial, Any plant that completes its life cycle in
two growing seasons
