PLANT KINGDOM
  • Anemophilous : It refers to the pollination that takes place with wind.
  • Angiosperms : Higher plants producing flowers with uretues enclosed in ovary.
  • Archegonium : Female sex organ in broyophytes and pteridophytes.
  • Bark : The outermost layer of corky tissue found in woody stem.
  • Bryophyta : (2500) plants with no vascular system placed under these classes :
  • Cambium : A group of meristematic cells in stems or root meant for secondary growth.
  • Carotene : It is an organ pigment made up of hydrocarbons.
  • Carpels or gynaecium : The carpels represent the female part of a flower.
  • Cotyledon : Embryonic leaf in a seed which stores food in case the seed is non-endospermic.
  • Dicots : It refers to plants having two cotyledons in their seeds.
  • Dicotyledons : These plants grow from a seed with two cotyledons. Their leaves are usually not vined and their flower parts tend to be arranged in four or five i.e. Tinospora.
  • Ephiphyte : These are the plants, that grow on other plants but do not take food and water form them.
  • Fucoxanthin : Its is an xanthophyll pigment of brown algae.
  • Haustoria : Specialised root like outgrowth which performs the function of absorbing food from the host.
  • Indusium : The protective covering of a sorus of a fern.
  • Inflorescence : The arrangement of flowers on the pedicle is called inflorescence.
  • Laminarain : The chief reserve food of brown algae.
  • Locule : The chamber in ovary.
  • Microsporophyll : A leaf or an appendage which bear one or more microsoporangia.
  • Monocotyledons : These plants grow from a seed with one cotyledons only. Their leaves are usually parallel vined and their flower parts such as petals and stamens tend to be arranged in three or six e.g. Dioscorea.
  • Oblique saprophyte : An organism which can derive its food only from dead organism or the non-living substances.
  • Orthotrophous : Straight ovule found in gymnosperms and some angiosperms.
  • Parthenocarpy : When fertilization fails, seeds are not formed but ovary wall is converted into fruit. This phenomena is called parathenocarpy.
  • Pedicle : The axis bearing flower in an inflorescence.
  • Plant : Plants are vegetable organism multicellular photosynthetic producers of biosphere, lack locomotive movement and possess chlorophyll, about 0.3 million described species spread into two major divisions.
  • Pneumatophores : They are breathing roots present in mangrove plant.
  • Prothallus : Small green, autotrophic, heart shaped gametophyte of ferm bearing sex organs.
  • Protonema : A branched filamentous juvenile stage of moss gametophyte from the lateral buds of which mature moss plants arise.
  • Rachis : Axis of fem leaf from which pinnae arise; also extension of petiole corresponding to midrib of entire leaf.
  • Ramenta : The small scaly structure covering the rhizome and petiole in fern for preventing desiccation.
  • Simple fruit : These are formed on the basis of one fruit from one flower, thus simple ovary on ripening forms the single fruit.
  • Siphonaceous : Multinuclear thallus but not divided into cell.
  • Sorus : A group of sporangia covered by indusium occurring on the underside of fern leaves.
  • Stele : Cylinder of vascular tissue is termed stele.
          Musci – mosses.

          Hepticaca – liverworts

          Antiocerotea – hornworts

  •  Gametophyte : It refers to gametic producing haploid phase of a plant.
  • Heterospory : It refers to existence of two types of spores i.e. microspores and megaspores.
  • Hydrophytes : These are the plants that are found in aquatic conditions.
  • Laminarin : It is the chief food reserve of brown algae.
  • Marine : Plants found in sea.
  • Monocosts : These are angiospermic plants having single cotyledon in their seed.
  • Orthotopous : It refers to straight ovule found in gymnosperms and some angiosperms.
  • Phycocolloids : It refers to a covering of algenic acid on cellulosic cell wall of brown algae.
  • Polyembryonic : It refers to formation of many embryos within single seed.
  • Pryenoids : It refers to startch storing proteinaceous bodies found in some algae.
  • Rhizome : These are underground, unbranched stems in ferns.
  • Siphonaceous : It is multinuclear thallus but not divided into cells.
  • Sporogonium : Sporophyte in bryophytes generally differentiated into foot, seta and capsule.
  • Sporophyte : It refers to spore producing diploid phase in a plant.
  • Syngamy : It refers to an act of fertilization.
  • Tracheophyta : (275000) all vascular plants grouped into four sub-divisions.
  • Xerophytes : These are the plants that grow in dry habitats.
