Plant reproduction

Plant reproduction

  • Heterogamy
    Heterogamy (from Ancient Greek ἕτερος heteros, "other, another" and γάμος gámos, "marriage") has a number of biological definitions.
  • Sporophyte
    A sporophyte (/spɔːroʊˌfaɪt/) is the diploid multicellular stage in the life cycle of a plant or alga.
  • Cotyledon
    A cotyledon (/kɒtᵻˈliːdən/; "seed leaf" from Latin cotyledon, from Greek: κοτυληδών kotylēdōn, gen.: κοτυληδόνος kotylēdonos, from κοτύλη kotýlē "cup, bowl") is a significant part of the embryo within the seed of a plant, and is defined by the Oxford English Dictionary as "The primary leaf in the embryo of the higher plants (Phanerogams); the seed-leaf.
  • Monoicous
    Monoicous plants are those species that bear both sperm and eggs on the same gametophyte.
  • Svalbard Global Seed Vault
    The Svalbard Global Seed Vault (Norwegian: Svalbard globale frøhvelv) is a secure seed bank on the Norwegian island of Spitsbergen near Longyearbyen in the remote Arctic Svalbard archipelago, about 1,300 kilometres (810 mi) from the North Pole.
  • Sowing
    Sowing is the process of planting seeds.
  • Budding
    Budding is a form of asexual reproduction in which a new organism develops from an outgrowth or bud due to cell division at one particular site.
  • Placentation
    In biology, placentation refers to the formation, type and structure, or arrangement of placentas.
  • Apomixis
    In botany, apomixis was defined by Hans Winkler as replacement of the normal sexual reproduction by asexual reproduction, without fertilization.
  • Vegetative reproduction
    Vegetative reproduction (vegetative propagation, vegetative multiplication, vegetative cloning) is a form of asexual reproduction in plants.
  • Cutting (plant)
    A plant cutting is a piece of a plant that is used in horticulture for vegetative (asexual) propagation.
  • Spore
    In biology, a spore is a unit of asexual reproduction that may be adapted for dispersal and for survival, often for extended periods of time, in unfavorable conditions.
  • Backcrossing
    Backcrossing is a crossing of a hybrid with one of its parents or an individual genetically similar to its parent, in order to achieve offspring with a genetic identity which is closer to that of the parent.
  • Fruit tree propagation
    Fruit tree propagation is usually carried out vegetatively (non-sexually) by grafting or budding a desired variety onto a suitable rootstock.
