Sweet Beets: Making sugar out of thin air

What is the job of the taproot? The main function of the taproot is to fix the plant and absorb water and inorganic salts from the soil.

What is the job of the leaves? To perform photosynthesis and thus supply food and energy to the plant.

What is the job of xylem? Xylem is the transportation organization of vascular plants, which is responsible for the transportation of ions absorbed by roots and ions dissolved in water.

What is the job of the phloem? The phloem in a plant helps brings nutrients to different parts of the plant. This is called translocation.

What is the job of stomata? The absorption of carbon dioxide to release oxygen in the light of the state of the closed pores to prevent water loss

Why do you think the beets grow best in deep soils? Within the range of 5 to 7.2, the root yield increased with the increase of pH. Sheng Bu soil over acid or alkali, sugar beet yield is relatively low. The deeper layer of soil, the more conducive to the growth of sugar beet root.

Why do you think the beets need a lot of sunlight? The energy required for plant life must be obtained from the sun by the process of photosynthesis and the production of organic matter. Sunshine is food for plants! Very important to plants!

How do the plant get water? In the rain day or person to get water

How do the plant get carbon dioxide Plant get the carbon dioxide from the air that surrounds them. The carbon dioxide naturally diffuses through extremely small pores in the leaves of plants.

Plot 2 graphs of the data above Blue：2012 Green : 2013

What pattern do you see from your graph? Winter have more carbon dioxide than summer.

Why is there more carbon dioxide in eth atmosphere in the winter? Because of the low temperature in winter, the sugar beet needs heat, in this process, there will be a lot of oxidation, so it will produce more carbon dioxide than other seasons
