Anther	—	See Stamen.
Angiosperms	—	Flowering plants with seeds en-closed in a fruit.
Asexual Reproduction	—	Reproduction by spores.
Assimilation	—	Conversion of digested foods into protoplasm.
Binomial Nomenclature	—	The system of denoting a plant or an animal by two Latin names the first for its genus and the second for its species.
Carpel	—	Floral part bearing ovules.
Centrosome	—	An area in animal cell which in-cludes a pair of small granules, called centrioles.
Chioroplast	—	A plastid which is green due to chlorophyll, pigment which makes plants look green.
Coelenteron	—	See gastro—vascular cavity.
Crop	—	The dilated middle pan of oesopha-gus in birds. It stores and softens hard grains.

Ovule	—	Structure produced by a flower, which later develops as a seed.
Parenchyma	—	Basic tissue of plants made up of cells, cellulose and inter—cellular spaces.
Plastids	—	Organelles present in plant cells, carrying pigments. See chlorophyll.
Plumule	—	Immature shoot system forming part of embryo of seed.
Pollen	—	Powdery substance discharged from anther of flower, male element in pollination.
Pollination	—	An act of transfer of pollen from anther to the stigma of the flower of same species.
Radicle	—	Immature root forming part of embryo of seed. Cf plumule.
Ribisomes	—	Organelles involved in assembling protein molecules as ordered by DNA.
RNA	—	Ribonucleic acid - self duplicat-ing nucleic acid concerned in protein synthesis.
Ruminant Stomach	—	A four chambered stomach in mammals like cattle, sheep etc.
Sexual Reproduction	—	Reproduction by gametes or sex cells.
Species	—	A term denoting a group of related plants or animals.
Stamen	—	Part of flower which produces male sex cells, comprising stalk plus head (anther) with pollen sacs that burst to release pollen grains.
Tissue	—	A group of similar cells doing one particular function.
