The document explains hydroponics, a method of growing plants without soil by using nutrient-rich water instead. Key requirements for hydroponic systems include fresh water with a balanced pH, oxygen for the roots, root support materials, essential nutrients, and special lighting for indoor growth. The assignment also prompts students to identify the agricultural technology discussed and to outline two steps in preparing a hydroponic system.

Hydroponics
In your own words explain the picture.

Hydroponics
Put simply: Hydroponics is a way to skip the soil, sub in
a different material to support the roots of the plant,
and grow crops directly in nutrient-rich water.

4. There are multiple approaches to designing hydroponic
systems, but the core elements are essentially the same.
What you need:
Hydroponics

5. Hydroponics
Fresh water: This is filtered with a balanced pH. Most plants like water
with a pH level around 6–6.5.

6. Hydroponics
Oxygen. Don’t drown your plants! In traditional farming, roots can get the
oxygen needed for respiration from pockets of air in the soil.

7. Hydroponics
Root Support. Hydroponic growing means growing plants without soil using
a liquid nutrient solution. This means it’s easier for nutrients to go straight
to the plant’s roots.

8. Hydroponics
Nutrients. Your plant is going to need plenty of magnesium, phosphorus,
calcium, and other nutrients to stay healthy and productive, just like plants
growing in the ground need healthy soil and fertilizer.

9. Hydroponics
Light. If you’re growing your plants indoors, you might have to invest in
some special lighting.
