Why don't you check at your Bio Book? it should have the definitions, or check the internet yourself to get the define words. Anyways here's the defintions.
Photosynthesis: formation of carbohydrates from carbon dioxide and a source of hydrogen (as water) in the chlorophyll-containing tissues of plants exposed to light
Alternation of Generation: the occurrence of two or more forms differently produced in the life cycle of a plant or animal usually involving the regular alternation of a sexual with an asexual generation
Vascular Tissue: plant tissue concerned mainly with conduction; especially : the specialized tissue of higher plants consisting essentially of phloem and xylem
Xylem: a complex tissue in the vascular system of higher plants that consists of vessels, tracheids, or both usually together with wood fibers and parenchyma cells, functions chiefly in conduction of water and dissolved minerals but also in support and food storage, and typically constitutes the woody element
Phloem: a complex tissue in the vascular system of higher plants that consists mainly of sieve tubes and elongated parenchyma cells usually with fibers and that functions in translocation and in support and storage
Ovum: a female gamete
Embryo: the young sporophyte of a seed plant usually comprising a rudimentary plant with plumule, radicle, and cotyledons
Fertilization: an act or process of fecundation, insemination, or pollination —not used technically
Seed: the grains or ripened ovules of plants used for sowing
Sperm: Male Gamete
