Procedures for experiments next week. Sunlight and starch production. Transpiration. Movement of water in stems. Will form new groups on Tuesday.
Continue in your microscopic examination of plant material. Be sure to document your observations thoroughly in your DSN. Sketches, photos, descriptions, measurements, labels. Organize your observations. Pose questions and follow them up. Reflect on how the structures relate to the functions (processes of photosynthesis, for example).
Examination of plant material under the microscope.
The purpose is to examine and contemplate the cellular organization of living things. Because green plants carry out photosynthesis, we want to witness first hand the structures that are involved. Remember that photosynthesis takes place in the cells.

It’s fun to think of the scale of things and how the accumulated effect of the actions of all the photosynthesizing plant cells in the world, impact the earth. Carbon, oxygen, and water cycles all are affected by photosynthesis. https://micro.magnet.fsu.edu/primer/java/scienceopticsu/powersof10/
- How do the structures of leaves, of cells, of chloroplasts relate to the functions? (This is always a big question in science.)
- See how the leaves you examine today correspond to the diagram. You might enjoy getting a print copy and coloring.
