Question

Plants that perform their entire life from seed to flower and then to seed within a single growing season is known as
A. Annuals
B. Biennials
C. Perennials
D. None of the above

Answer 1

Hint: Annuals area unit plants that perform their entire life cycle inside one season. whereas biennials complete their life cycle in 2 years & Perennials live for quite 2 years.

Complete Answer:
Cryptogam is any of a bunch of plants or plant-like organisms (as protoctista and fungi) that lack differentiated stems, leaves, and roots which were at one time classified as a primary division (Thallophyta) of the Plantae.

1. Annuals: Plants that perform their entire life cycle from seed to flower to seed among one season. All roots, stems and leaves of the plant die annually. solely the dormant seed bridges the gap between one generation and to boot consecutive.

2. Perennials: Plants that persist for several growing seasons. generally the simplest portion of the plant dies back every winter and regrows the subsequent spring from constant themes (e.g. Purple Coneflower). Several perennial plants do keep their leaves year spherical and provide partaking borders and groundcover (e.g. Tickseed, Shasta and eyed Daisy). Once beginning perennial plants from seed, blooms are reaching to be ascertained in either the spring or summer of the second year and every year thenceforth (e.g. flower planted within the spring of 1996 won't bloom till the spring of 1997).

3. Biennials: Plants that need a combine of years to end their life cycle.
First season growth finally ends up in a tiny low rosette of leaves getting ready to the soil surface. throughout the second season's growth stem elongation, flowering and seed formation occur followed by the whole plant's death.

4. Annual/Perennial: A plant will behave as Associate in Nursing annual or a perennial counting on native condition and geographic growing conditions. Within the southern portion of the North yank country, these plants tend to grow a lot faster than within the north because of the hotter weather and extended season. For example: a Black-Eyed Susan would behave as Associate in Nursing annually if grownup in Louisiana; whereas, if grownup in Ohio, a Black-Eyed Susan would behave as a perennial.

Note: These square measure plants that germinate, acquire flowers, set seed and die in one season or year. By gathering the seeds, you'll be able to grow them year once year. Hardy annual seeds square measure seeded within the specific website wherever they'll flower.
