Like all living things, plants can perform the three vital functions of nutrition, interaction and reproduction. PLANT NUTRITION Plants use autotrophic nutrition. In order to carry out this process, they start by taking in inorganic matter through their roots and leaves: Water and the mineral salts form the raw sap which travels to the leaves through the vessels […]

CELLS
Biomolecules group together to create cells: the smallest structures that can be considered living things. Cells are the functional and structural units of all living things. All living things, including human beings, are made of cells. This is why cells are structural units. At the same time, cells are the smallest structures capable of performing the three […]

Atoms are the first structural level of matter and they organise themselves into molecules. We know 117 different types of […]
