reproduction in plants (21 cards)
Cuttings
taking piece of plant shoot and planting in compost, asexual reproduction
Pollen grains
structure in plants, contains male gamete
Ova
female gamete
Pollination
transfer of pollen from anther to stigma
Seed
structure formed from ovule following fertilisation, contains embryo plant and food store
Fruit
structure containing seed(s), formed in ovary after fertilisation
Anthers
part of stamen where pollen grains are produced
Stamens
male reproductive organ (plant), consists of anther and filament (stalk)
Ovules
structure in ovary of plants, produces ova
Ovaries
female reproductive structure in carpel of flower, contains ovules
Stigma
part of carpel of flower, receives pollen during pollination
Self-pollination transfer of pollen from anther to stigma of same/other flower same plant
Cross-pollination
transfer of pollen from one plant to another’s stigma (same species)
Pollen tube
tube grows from pollen grain to allow transfer of male gamete to ovule for fertilisation
Style
part of carpel of flower, stalk connecting stigma to ovary
Radicle
embryonic root of plant
Plumule
embryonic shoot of plant
Testa
seed coat
Cotyledons
seed leaves, can be food store in leaves
Dicots
plant with 2 seed leaves
Monocots
plant with 1 seed leaf
Germination
sequence of events where embryo in seed develops into young plant
