Helophytes are plants in which the roots lie under the soil below the water level, but the aerial shoots protrude and develop above the water. Examples include Typha minima, common reed, etc.

A. Apospory -include formation of Diploid gametophytes, without meiosis and spores, from vegetative cells of the sporophyte. for example - mosses and ferns.
B. Heterospory- is fornation of spores of two different sizes i.e smaller of these, the microspore, is male and the larger megaspore is female by the sporophytes of land plants. for example -pteridophytes -Selaginella and Salvinia.
C. Parthenocarpy is the development of a fruit without fertilization, which makes the fruit seedless, for example- Pineapple, banana.

A. Xerophyte- are plant that has adaptations to survive in an environment with little liquid water, such as a hot or cold desert. for example- cacti, pineapple and some Gymnosperm plants.
B. Halophyte- grows in waters of high salinity, as they are salt-tolerant plant. for example- Avicennia, Rhizophora, Atriplex.
C. Hydrophytes- are aquatic plants, which grows only in or on water.for example- Lotus, water lily, salvinia.
D. Mesophytes- a plant need only a moderate amount of water. as they are terrestrial plants which are neither adapted to particularly dry nor particularly wet environments. for example-goldenrod, clover, Rosa multiflora
