Collect information about plant classification

Answer 1

Plant species can be classified based on their life cycle.

Annuals

These are plants that complete their life cycle during a single season. They are normally herbaceous. Examples like corn, rice, wheat, and pulses are annuals plant.

Biennials

These are plants that require two years to complete their life cycle. They are normally herbaceous. For example, carrot, cabbage, onions, and beetroot are biennials plant.

Perennials

These are plants that have a long lifespan – typically more than two years. They are characteristically woody or herbaceous. Rose, lavender, dianthus, and lilies are prominent examples of perennials.

Taxonomy is a system for classifying plants based on their genetic and evolutionary relationship. Plant Taxonomy is a branch of science that continues to change as new species are being found almost every day.

Plants are classified into a separate kingdom called the Kingdom Plantae. This current system of classification of plants is based on the evolutionary relationship amid other plants.

Coniferophyta (Gymnosperms):

It is a group of plants which is primarily evergreen and are native to the temperate zone. There are about 700 species discovered to date. They are vascular, non-flowering plants which produce seeds without the production of flower and fruits. Some common examples of gymnosperm include pines, cycads, cedars, etc.

Anthophyta (Angiosperms):

They can grow into big trees as well as small shrubs, bushes and herbs. The angiosperms are distributed all over the world (>250,000 species). Most of the plants that we see around us are grouped under this division.

Angiosperms are characterised by the seeds that are fully enclosed in fruits. They are subdivided into- Monocotyledonous and Dicotyledonous. Some common examples of angiosperms include mango trees, roses, jasmine, marry gold, etc.

Monocotyledons:

Monocotyledonous plants are commonly referred to as monocot plants. They are flowering plants with seed containing one cotyledon. The venation pattern of their leaves is parallel-veined. Some common examples of monocot plants are rice, corn, sugarcane, tulips, onion, etc. There are around 50,000 species of monocotyledonous plants discovered to date.

Dicotyledons:

Dicotyledonous plants are commonly referred to as dicot plants. They are flowering plants, mostly grown as herbs, shrubs, and trees with the seed containing two cotyledons. The venation pattern of their leaves radiates from a central main vein. Some common examples are figs, eucalyptus, potato, tomato, hibiscus, etc. There are around 200,000 species of dicotyledonous or dicots plants.

Answer:

Classification within Kingdom Plantae

1. Thallophyta.
2. Thallophyta.Bryophyta.
3. Thallophyta.Bryophyta.Pteridophyta.
4. Thallophyta.Bryophyta.Pteridophyta.Gymnosperms.
5. Thallophyta.Bryophyta.Pteridophyta.Gymnosperms.Angiosperms.

Thallophyta

Thallophytes are a polyphyletic group of non-motile organisms traditionally described as "thalloid plants", "relatively simple plants" or "lower plants". They form an abandoned division of kingdom Plantae that include fungi, lichens and algae and occasionally bryophytes, bacteria and slime moulds.

Bryophyta

Bryophytes are an informal group consisting of three divisions of non-vascular land plants (embryophytes): the liverworts, hornworts and mosses. They are characteristically limited in size and prefer moist habitats although they can survive in drier environments. The bryophytes consist of about 20,000 plant species.

Pteridophyta

A pteridophyte is a vascular plant that disperses spores. Because pteridophytes produce neither flowers nor seeds, they are sometimes referred to as "cryptogams", meaning that their means of reproduction is hidden. Ferns, horsetails, and lycophytes are all pteridophytes.

Gymnosperms

The gymnosperms, also known as Acrogymnospermae, are a group of seed-producing plants that includes conifers, cycads, Ginkgo, and gnetophytes. The term "gymnosperm" comes from the composite word in Greek: γυμνόσπερμος, literally meaning "naked seeds". The name is based on the unenclosed condition of their seeds.

Angiosperms

Angiosperms are plants that produce flowers and bear their seeds in fruits. They are the largest and most diverse group within the kingdom Plantae, with about 300,000 species. Angiosperms represent approximately 80 percent of all known living green plants.
