Plant and animal life

How does a plant breath ? How does the process of photosynthesis occur? What happens if we try to change some significant parameters while we study a vegetable’s activity? Do the eye and the skin breath? The answer to these questions is in the biology books, without the support of an adequate experimentation. Thanks to the on-line items mentioned in this section the teacher can observe “ live” the behaviour of biological organisms, and then analyze the experimental data to establish relations between parameters and try to represent them mathematically.
