Mr. George’s Prathom Six Science students have been in the lab using EIP’s microscopes to look at cells dealing with reproduction.
A cell is the basic unit of life, because their individual cells carry out all the functions carried out by living things.
Two scientists (Matthias Schleiden and Theodore Schwann) who studied cells combined their observations to make a hypothesis … all living things are made up of cells.
Rudolf Virchow contributed his observation and together the Cell Theory was formulated:
• all living things are composed of one or more cells
• cells are the basic units of structure and function in all organisms
When viewed with a compound light microscope these cell structures become visible to the naked eye. There are certain factors that can affect what you are able to see inside a cell.
These factors are:
• The type of microscope you use
• The power of the lenses
• The quality of the prepared slides
All cells, plant and animal, have structures and each structure performs a specific function in order for the cell to maintain life. The specialized structures inside the cell are called organelles and they carry out specific functions.
