Life of a plant: from seed to seed'

Life of a plant from seed to seed.

Germination

• Definition the first stage or the beginning
  growth of a seed to plant
• Water enters the seed through the little hole at
  the side called the - Micropyle
• The water activates gibberellin - A hormone
  needed to break the dormancy of the seed.
• The seed then shoots off roots and the seed then
  absorbs water and nutrients from the soil.

3
Leaves

• Cotyledon - are the first leaves after the
  germination stage.
• Monocotydon only having one cotyledon.
• Dicotyledons (Dicot) - is the name for the group
  of plants having two cotyledons.

• After that stage there comes the first true
  leaves.

4
Photosynthesis

• Photosynthesis is the process of the plant
  absorbing sunlight and converting it to nutrients
  and sugar.
• To begin the plant only needs light, CO2 and H2O
  to make sugar.
• Photosynthesis releases water, oxygen, and
  glucose.

• The leaves basically produce photosynthesis. This
  is because of the vascular bundles ( the vain
  looking things)

5
Nutrients

• The plants need 12 kinds of nutrients from the
  soil.
• Nitrogen, phosphorus, potassium, calcium,
  magneslum, sulphur, iron, manganese, zinc, boron,
  copper, and molybdenum.
• Just like we need nutrients a plant also needs to
  have the right amount of nutrients to produce
  good crop growth.
• If the plant does not have the necessary
  nutrients it will result in poor crop growth.

6
Sunlight and water

• Most plants need about 4 to 6 hours of sunlight a
  day
• But some need less or more sunlight then other
  plants do.
• Direct and indirect sunlight affect the growth
  of a plant
• Having more sunlight can speed up the process of
  growth.

• Its very important to keep the soil consistenly
  moist
• If you dont, the chance your plant will die will
  increase.
• Plants, especially when there young, are very
  delicate.

7
Pollination

• Pollen are yellow tiny egg-shaped male cells of
  flowering plants.
• The transfer of pollen from the stamen (male part
  of the plant) to the stigma (female part of the
  plant).
• Pollination can happen by the wind, and insects
  or water.
• The percentage of pollination transfer is, 2 by
  water and 98 by the wind.

8
Stress

• If the plant isn't getting enough or is receiving
  too much sunlight and/or water the plant will
  mature faster.
• Because its trying to get nutrients from the
  soil.
• If the plant doesnt have the nutrients it needs
  that causes if to be under stress.
• Pest/insets eating the plant causes it to stress
  out as well.

• Another thing is when the plant is under stress
  it will seed for the next generation.
• In addition weed competition is another factor to
  cause stress.
• When the plant holds to much stress it will
  result in growth stunted growth.
• On the farm we cleared out the blackberries so
  the evergreen trees is grow larger.

Under what condition will it seed

• Temperature - A seed will germinate quickly and
  vigorously with the right temperature. This is an
  important point to consider. Sometimes you can
  see the temperature the seeds need to germinate
  on the back of the packet or you look it up in a
  book.
• Moisture - seeds need to be moist in order to
  grow. If you give it too much water you will cool
  it down.

• Light the amount of light varies from seed to
  seed. Some seeds germinate in the light while
  some germinate at night. Check on the packet you
  bought the seed or look it up in a book
• Once your seed germinates, it is now a seedling.
  Seedlings dont need high temperature but they
  need warmth.
• Seedlings need protection form draughts and pest
  and diseases.

10
Saving And Protecting

• Saving
• If you have bad insects try to get beneficial
  insect to eat them.
• If you have too many plants growing in one area,
  take some out, that will make the plant grow
  faster and healthier.
• Sometimes plants just need water and sunlight

• Protecting
• Seedlings needs protection form draughts, pest
  and diseases.
• Weather changes. (snow, heat waves, floods, ect)
• Animals can be a big problem too. (deer, gofers,
  and other animals that live underground.)

11
Saving/Storing Seeds

• When you harvest them too soon, your seeds will
  produce thin and unsubstantial food.
• But if you wait too long to collect your seeds,
  you are in danger of losing them to wind or
  animals.
• The majority of seeds like to be stored in cool,
  dark and dry circumstances. (Note that some
  seeds vary)
• If you store them correctly they could last for
  40 years!
