Requirements for Plant Growth and Development

1
Requirements for Plant Growth and Development

• Agri-science
• Mr. Bailey

2
Your TASK!!!!

• Make a list of requirements for basic survival
• You have two minutes
• shelter, water, food, air, and clothing

3
Your TASK!!!!

• Pretend you are plant
• List the requirements for survival
• You have two minutes
• soil, water, nutrients, air, and light

4
What is meant by growing media?

• Growing media whatever material a plant grows in
  and gets nutrients from
• May be soil or a soil substitute
• such as peat moss, perlite, or even water.

5
What is meant by growing media?

• Place for its roots to grow and a place from
  which it can absorb nutrients
• The media acts as a shelter for the plant by
  giving it a place to grow, just as humans must
  have a place to live.

6
What nutrients do plants need?

• Just as humans need food to survive, plants need
  nutrients to grow.
• Plants need three main nutrients
• Nitrogen, Phosphorus, and Potassium
• N, P, and K
• From the media in which they grow, but more
  nutrients may need to be added

7
What is water's role in a plant's life?

• Plants get the water they need in several ways
• 1) Directly from rain, irrigation, misting, or a
  bucket
• 2) Absorb it through their roots
• 3) Absorb water that is in the air
• Water in the air is called humidity.

8
What is a plant's relationship with air?

• Plants clean the air
• Plants absorb carbon dioxide from the air and
  use it to produce food
• They give off oxygen as a by-product of this
  activity.

9
What is light's role in a plant's life?

• Must have light in order to make food and they
  must have food to live.
• The process of making food from light is called
• photosynthesis and takes place in the plant's
  leaves.
• The amount of light affects whether or not the
  plant will bloom. Plants can live in either
  sunlight or artificial light.

10
Activity Time!!!!!!!

• Your group will construct a garden terrarium
  using one of the following
• Plastic 2 litter bottle
• 1 gallon Milk jug
• 20 oz. Plastic soda bottle

11
Conclusion

• Plants and humans have very similar needs for
  survival.
• Remembering what people need in order to live can
  serve as a reminder of what plants need.

  lights role in a plants life?

  growth?
