What is vascular tissue exactly?

Spiderwort Leaf(stomata)

Photosynthesis:

1) The 2 substances required for photosynthesis are:

2) The main product of photosynthesis is:

3) The waste product is:carbon dioxide (CO2 ) and water (H2O)glucose (C6H12O6)oxygen (O2)Anatomy of a Leaf

You should be writing down anything you see in RED.

For photosynthesis to take place, leaves must have a constant supply of:CO2 and waterLeaves must get rid of:O2 and excess water vapor

animals do this all the time; plants ALSO do it when theyre not doing photosynthesis.Write This Down!
