06 Main Plant Growth Factors

Question 1

Light

Answer 1

Needed for:
-photosynthesis
-transpiration

Question 2

Air

Answer 2

Plants require both Carbon Dioxide and Oxygen to survive

1. Carbon Dioxide
   -used in photosynthesis
   -combines with water to create glucose (sugar) which is how plants store energy to use it later (when it is dark out)
   -process takes place in chloroplasts within the plant cells and releases Oxygen
2. Oxygen
   - used in the process of cellular respiration
   - glucose (sugar) is broken down in the mitochondria of the plant cells allowing the stored energy to be released and used by the plant cells to function
   -process releases Carbon Dioxide

Question 3

Water

Answer 3

Used for:
-photosynthesis
-dissolving minerals and other substances to allow them to move within the plant
-creating turgor pressure within the cells so that the plant can remain upright (plants wilt without water)
