Exam Outline


The resources/activities in blue are the ones provided by Mr Nicoll. The ones in red are ones we can do/prepare ourselves.

Transpiration


For homework, we had to COMPARE AND CONTRAST nutrient transport in plants and in humans.

The set up for one group. The water in the petrie dish has purple food colouring in it.

One group's results: notice the food colouring in the xylem tissue.




Leaves


We agreed that plants only need leaves to absorb sunlight and carbon dioxide for photosynthesis. They actually prevent water entering them, except from the roots via the stem and veins.


The key parts of the leaf cross-section that we were encouraged to talk about were: wax cuticle, palisade cells, air spaces, stoma, guard cells, and the spongy mesophyll.
