HOW PLANTS GROW

LEAF STEM ROOTS

TWO PHASES OF PLANT LIFE CYCLE  VEGETATIVE STAGE Includes the growth of roots, stem and leaves. Includes the growth of roots, stem and leaves.

THREE ESSENTIAL CONDITIONS FOR GERMINATION 1.Amount of moisture which is needed to soften the seed coat and to help in the circulation of food which seed contains.

2. OXYGEN which when moisture is absorbed, oxygen takes in and carbon dioxide is given off by the seed. 3. WARMTH AND AIR IN THE SOIL which are needed to germinate seeds.

DEVELOPMENT OF SEED HYPOCOTYL COTYLEDON RADICLE EPICOTYL

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  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  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.

PARTS OF THE FLOWER

PISTILS  Are the female parts of the flower which consists of an ovary with an upright extension. The stigma which lies on top of the style serves as the pollen-receptive surface.

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  Takes place when a male nucleus in the pollen tube unites with the female nucleus of the ovules through the process called pollination.
