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
Compare the two lists

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.
Talk about wilting and how it relates to people’s skin

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.
