Answer:
1. Gymnosperms - Gymnosperm usually produces both a Female or seed cone and a Male or pollen cone. The seeds develop in the exposed upper surface of the Female cone and are fertilized by pollen that is released from the Male cone and carried by the wind. It consists of Plants that produce a Cone, such as Pines, Firs, Cedars and Redwoods. These are the Plants of the class Gymnospermae whose seeds are not enclosed in an ovary or fruit.
2. Angiosperms - Angiosperms are the Plants which have flowers and their seeds are enclosed in a protective shell called a 'Fruit'. Angiosperms are also known as 'Flowering Plants'. The Angiosperm group consists of over 250,000 Species of Flowering Plants, making it the most diverse of all Plant Phyla.
3.Thallophyta
They are usually found in moist or wet places. This is due to the absence of “true roots” and vascular tissue that is needed to transport water and minerals. ... They are autotrophic in nature. Most members in this group manufacture their own food. ... Reserve food is generally starch.
4.bryophytes
Their life cycles are dominated by the gametophyte stage. Their sporophytes are unbranched. They do not have a true vascular tissue containing lignin (although some have specialized tissues for the transport of water)
5.Pteridophyta
Pteridophytes are the first true land plants: ... They are seedless, vascular cryptogams: ... They show true alternation of generations: ... Sporophyte has true roots, stem and leaves: ... Spores developed in sporangia are homosporous or heterosporous: ... Sporangia are produced in groups on sporophylls:
