Activity 2 

The objective, to distinguish between:

Photosynthesis;

Respiration;

Evapo-perspiration.

Using examples, videos and demonstrations, show the students that plants feed themselves, breathe and perspire.

Activity 3: Tropisms

Distinguish three types of movement in plants:

Phototropism;

Hydrotropism;

Geotropism.
