Plant life cycle
Life cycle : is a series of different stages of development
Alternation of generation : the process of alternating between asexual and sexual reproduction. Ex : Moss life cycle and Fern life cycle
Flowers : are the reproductive organs of organism
Complete flower : the flower that has the all of the four main parts: petals, sepals, stamens and pistils
Petals : are the brightly colored outer parts of the flower
Sepals : are the green part below petals and protects the flower's part when it just a bud
Stamen : is the male part of the flower
Pistil : is the flower's female organ made of stigma, a style and an ovary
Filament : is the thin stalk portion of the stamen
Anther : is at the top of filament and produces pollen grains
Stigma : is the opining at the top of the pistil
Style : is the long necklike structure that leads down to the ovary
Ovary : the house of egg cells and it is the place where fertilization occurs
Incomplete flower : is missing one or more of the flower parts of a complete flower
Perfect flower : has both stamens and a pistil the male and female parts) ex : lilies, gladioli and tulips Incomplete perfect
flower : has both male and female structures but missing petals. Ex: windflower
Imperfect flower : a flower lack either a stamen or a pistil. ex : willow trees Pollination: the transfer of pollen from the stamen to the pistil
Pollen : is a yellow powder that contains sperm cells
Nectar : is a sweet liquid produced by flowers to attract pollinator
Self-pollination : it occurs when a perfect flower with both male and female parts pollinates itself
Cross pollination : it occurs when the pollen from one plant pollinates a flower on a different plant
Embryo : is the beginning of a new offspring
Seed coat : is the cover surrounding the seed. Germination is the development of a seed into a new plant
Monocot : a type of flower that produces seeds with a single cotyledon. Ex : com plants, orchids and grasses
Dico : a type of flower produces seeds with two cotyledons. Ex : bean plants and roses
Conifer : is a gymnosperm, a plant that has seeds but not flowers
