Plant Growth & Development

Plant Growth Development

• Lea Ann Sutherland

Seeds

• Are essential to the survival of many plant
  species
• The life cycle of a plant species begins with the
  seed
• The seed contains an embryonic plant composed of
  radicle (baby root), cotyledon (seed leaf), true
  leaf, seed coat.

5 Necessary Conditionsfor seeds

• Viable Seed
• Germination medium
• Moisture
• Optimum Temperature
• Oxygen

5
Germination- (process causing seed to sprout and
grow)

• Steps to germination
• The seed absorbs water and oxygen
• The seed coat ruptures permitting the young root
  (radicle) to emerge and grow downward to anchor
  the plant
• The above soil surface portion of the plant
  emerges
• New leaves form and photosynthesis begins

Photosynthesis

• The process by which the plant manufactures food
• photo- light synthesis- putting together
• Chemical Terms- process whereby certain living
  plants combine carbon dioxide (CO2) water(H2O)
  in the presence of light, chlorophyll, and
  enzymes to form carbohydrates, mostly
  glucose(C6H12O6, a simple sugar)

• Respiration
• A plant uses food produced during photosynthesis
  to form energy
• which is stored and released
• Transpiration
• Release of water vapor through plant leaves

Plant People

• 1 knee high
• 1-2 tablespoons seed
• About 1 ½ cups of soil
• 2 eyes
• 1 piece construction paper
• Other desired decorations
• Hot glue (be very careful)

Plant people continued

• 1st pour seed into hose
• pour soil into hose, enough to make the size of a
  baseball
• tie hose in a not so the soil and seeds are
  compacted and not loose
• Hot glue eyes on
• Nose and mouth if wanted
• After dry submerge the head in water until
  completely saturated

12
Plant people continued

• Set aside the head
• Decorate can (body) as desired
• Fill can ½ full w/ water
• Stick hose down into can to absorb water w/ head
  resting on top
• Now you have your very own Plant Person!!!
  Check water daily watch its hair grow
