Wednes-Day 2
Bio- hw text section 9.3 outline is due on Thursday. Bring in your Aerobic Respiration Rate lab to be completed in class tomorrow.
We looked at the big picture of photosynthesis and cellular respiration starting with the macroscopic view of a plant leaf and then focusing on the processes that go on in an individual plant leaf cell. We got through the photosynthesis part of the big picture and up to the glycolysis part of cellular respiration. Tomorrow, we will complete the whole picture and see the inter-relationship between the two processes. After looking at the leaf parts and the individual plant cells, we detailed the processes INSIDE each cell in the relevant organelles (the chloroplasts, mitochondra) and in the cytoplasm within a cell. We looked at even smaller details as we discussed the processes in different parts of each organelle, the granum and the stroma of the chloroplast as well as the inner mitochondrial membrane of the mitochondria.
We ultimately focused on the smallest possible units involved in photosynthesis and respiration: the molecules- chlorophyll, water, carbon dioxide, enzymes, ATP, glucose, oxygen, pyruvic acid, etc. and noted their respective locations within the organelles or cytoplasm of a cell.
Chem 7/8- took the Atomic Structure unit exam; so far I am impressed with the explicit detail provided in your answers, the attention to test skills, and the correct spelling of the word "neutron"- very good!
We completed the discussion and write-up of the Emission Spectra and Flame Test lab.
Chem 9- took the Atomic Structure unit exam; I'll try to have them graded by tomorrow.
Tomorrow, we begin the Periodic Table, which is a natural continuation of the Atomic Structure unit. So, if there was anything that gave you trouble on the test today, make sure that you get that cleared up (written review, extra help, repetition, practice) before we get into this new unit.
