Ch. 9.1 Single-celled organisms have all the characteristics of living things
Vocabulary: matter, molecule, species, binary fission, kingdom, microorganism, virus
9.1 Review
1. very large organism: huge fungus, very small organism: single-celled bacteria
2. growth, reproduction, organization, and response to environment
3. enery, material, and living space
4. A dog is made of cells that perform specific functions. It starts as a puppy. As its cells reproduce, it grows to a full-sized dog. Male and female dogs reproduce sexually to create more puppies. Dogs bark at, run at, or run from different things they sense.
5. There is room in a lake for many billions of microscopic organisms but not for nearly as many larger organisms.
6. (Drawings will differ.)

Ch. 1.1 The cell is the basic unit of a living thing.
Vocabulary Words: cell, genetic material, organism, theory, unicellular, multicellular, microscope, bacteria
Review 1.1
1. organization, growth and development, response to environment, reproduction
2. It allowed people to see cells. Before the microscope humans did not realize that life could be so small.
3. Every living thing is made of one or more cells; cells carry out the functions needed to support life; cells come only from other living cells.
4. The cell theory is widely accepted and explains observations of nature, and is supported by evidence such as Pasteur´s experiments.
5. multicellular: many cells, complex, easier to see; unicellular: one cell, cannot be seen directly; both: need energy, materials, and living space
6. In Pasteur´s experiment, bacteria did not grow spontaneously. They came from the environment, which indicates that cells come from other cells.
