Osmosis and transpiration

 

Today for science we have been learning about osmosis and transpiration. During this task we used a celery to see the tiny tubes inside which will absorb the water to the leaves. 

We first learnt about photosynthesis which is the method on how a plant grows and how they become food. The leaves are the part of a plant where photosynthesis happens. Tiny Cells and special cells help to distribute food in different parts of a plant. This method is called phalon and xylem. 

Next we did the experiment which was using a conical flask, water, food colouring, water, bag, and a twist tie. Using these ingredients can help us observe the movement of the water from the roots to the leaves through xylem. 

Lastly, we cut open the stems of the celery to see the coloured water going through the stalk. This shows how much water has been absorbed.

I found this session interesting because I learnt the procedure on how a plant absorbes water which goes through the cells.
