two phases of plant life cycle
TWO PHASES OF PLANT LIFE CYCLE
  • VEGETATIVE STAGE

Includes the growth of roots, stem and leaves.

three essential conditions for germination
THREE ESSENTIAL CONDITIONS FOR GERMINATION
  • Amount of moisture

which is needed to soften the seed coat and to help in the circulation of food which seed contains.

slide7

OXYGEN

  • which when moisture is absorbed, oxygen takes in and carbon dioxide is given off by the seed.
  • WARMTH AND AIR IN THE SOIL
  • which are needed to germinate seeds.
development of seed
DEVELOPMENT OF SEED

HYPOCOTYL

EPICOTYL

RADICLE

COTYLEDON

hypocotyl
HYPOCOTYL
  • It is the part of the embryo that first grows downward into the soil form a stem of the seedling. This hold the plant in place and gathers moisture and food in the soil.

EPICOTYL

  • It is the young leaves of the new plant.
reproductive stage
REPRODUCTIVE STAGE
  • It is the stage where the development of flowers, fruits and seeds takes place.
  • It is also the stage in plant life that begins with the production of flowers and end with the maturing seeds.
flower
FLOWER
  • It is a specialized branch of plant

designed for sexual reproduction or production of seeds.

  • It is made up of organs like sepals, stamens, pistils, petals and accessory organs for reproduction.
pistils
PISTILS
  • Are the female parts of the flower

which consists of an ovary with an

upright extension.

Thestigmawhich lies on top of

the style serves as the pollen-receptive surface.

stamens
STAMENS
  • compose the male parts of the flower,

each of which consists of a supporting filament and an anther where the pollen grain is produced.

fertilization
FERTILIZATION
  • Takes place when a male nucleus in

the pollen tube unites with the female nucleus of the ovules through the process called pollination.
