We learned the basics of photosynthesis, that is that the plant takes in water from its roots via the xylem and sends it up to the leaves via the petiole. The sun converts some of this to water vapor. The plant takes in CO2 via holes on the underside of it's leaves by a feature called Stomata. There are many of these on any given plant's leaves. Then, the sun splits the water molecule into hydrogen and oxygen molecules. Then, the sun helps to run a reaction between the hydrogen and carbon dioxide that forms carbohydrates and simple sugars. The plant sends this food down to the roots via the phloem. We also learned that plants which flower are called angiosperms.
Megan drew a picture of a plant and its root, stem,and leaves. We discussed the parts of the root and talked about a tap root versus a plant with roots that spread out along the surface. The root in the book looked like a tap root.
We also talked about how in woody plants such as trees, they grow upward and outward, that is the trunk gets wider and longer. Also, it discusses how there is a ring for each year of tree growth.
we also watched a Rap UTube video on the parts of a cell.
