3. 1.1 Studying the Structure of Cells
(Page 7)
The development of the microscope in the 1660s increased our understanding of the human body and led to the discovery of cells.
Cell – the smallest unit that can perform the functions of life
Microscopy – the science of using microscopes to view samples or objects

6. Cell Structure
(Page 10)
One of the first structures to be seen clearly through a microscope was the nucleus.
The nucleus is the organelle that controls the cell’s activities.
Organelles are specialized structures within a cell.

7. The Cell Theory 2. The cell is the basic organizational unit of life.
(Page 11)
The Cell Theory was proposed by German scientists in the late 1830s. Theodor Schwann and Matthias Schleiden used their studies of plants and animals to formulate the first two ideas. In 1855 Rudolph Virchow added the final one. The theory states that:
1. All living organisms are made of one or more cells.
2. The cell is the basic organizational unit of life.
3. All cells come from pre-existing cells.

8. Animal and Plant Cell Organelles
(Pages 12-13)
Animal Cells
Plant Cells
The cytosol (the fluid material between the cell membrane and the nucleus) is filled with many specialized organelles.
There are some important differences between the organelles found in plant and animal cells.

(Page 14)
Cellular Respiration – a process that releases energy from organic molecules, especially carbohydrates such as glucose, in the presence of oxygen
Mitochondria – the site in animal and plant cells
where cellular respiration takes place
