Lecture 2- Digestion
- Most plants are photosynthetic autotrophs, which means that they take
carbon dioxide and water and light and synthesize carbohydrate and in the
process liberate oxygen. Of course they also synthesize their own protein,
lipids and nu
Lecture 13 - Nervous system 3
- SYNAPTIC POTENTIALS
Synapses are special structures that pass information from neuron to neuron (or to muscle or
gland cells in certain cases).
The synapses, therefore, involves parts of two cells, the presynaptic (the one

Lecture 4- CIRCULATION
- Circulation of the blood is to deliver nutrients, salts and hormones to tissues
and take away the waste products and carbon dioxide.
- However diffusion only works well over short distances

- They need to be multicellular in order to get big and still be able to do all of
the regular functions
o For example, single celled organisms can only get to a certain amount
of big because the surface area when you
