What are the characteristics of a seed plant?
Seed plants are vascular and reproduce by seeds.
We talked about the two types of vascular tissues:Xylem and Phloem. We also talked about the structure of leaf. The chlorophyll of a plant is found below the upper part of the leaf.That's so it can absorb the rays in the sun, and help in carrying out the process of photsynthesis. Stomata are found on the bottom part of the leaf. In between the top and the bottom cells are Xylem and Phloem tissues. We also reviewed about vascular and nonvascular plants.
After that we worked on a new lab. We looked at a tree cookie. We counted the rings to find its age. We completed the lab today, as well as the moss lab that we woked on yesterday. This was turned in for a grade.
Progress reports were sent home.
