Topic 7: Osmosis and Transpiration.
Task 1
Photosynthesis - Food
Co2 + H20 Sunlight Sugar + o2
Source of carbon - humans & animals
Roots absorb water
Phloem is a special type of cell to distribute food/sugar to different parts of a plant.
Stoma are tiny pores on leaves to help absorb Co2
Celery & Food Colouring Experiment:
See water movement from roots to the leaves through xylem.
Supplies for experiment:
Celery
Water
Conical flask
Food Colouring
Method:
Fill a Conical Flask with approximately 200 mls of water.
Then taking any food colouring of your choice and adding 10 drops to the conical flask filled with water. You then take 2 pieces of celery, cut equally and add to your conical flask and stir, then take a clear plastic bag and wrap it around the leaf, then you twist it using a twist tie.
Observation:
What I am going to see as an outcome from this experiment is hopefully the xylem by the water moving to the leaf.
