Unit 1: Basic Biological Priciples

There are many criteria that are used to define living things. Living things reproduce, grow, and develop. They respond to stimuli, use materials and energy, and evolve and adapt over time to their environment. What is another criteria used to define living things?

• All living things are made of cells.
• All living things are intelligent.
• All living things are complex.
• All living things are able to move.

• Eukaryotic cells are only found in protists, bacteria, and viruses.
• Eukaryotic cells are the only type of cells that can possess a cell wall.
• Prokaryotic cells do not have a true nucleus or membrane-bound organelles.

Prokaryotic and eukaryotic cells have many differences, but they also share some common features. Which of the following may be found in either type of cell?

• cell walls
• Golgi bodies
• mitochondria
• nuclei
