1.      Organism: a living thing made up of a cell or cells.

A bacteria is an organism that can make people sick.

2.   Nutrient: a substance that is needed for growth and survival.

We all need nutrient substances for food.

2.      Reproduce: to make more of the same kind.

I am trying to reproduce that picture on the Xerox machine.

3.      Classify: to put into groups by a system.

We are going to classify this group of insects by whether or not they have wings .

4.      Kingdom: the largest group into which an organism can be classified.

Do trees belong to the animal or plant  kingdom?

5.      Moneran: an organism with no membrane around its nucleus.

Regular bacteria are moneran and some are good while others are dangerous.

6.      Protist: a one-or many-celled organism with a membrane around each nucleus; use sunlight or eat food to get energy.

Slime molds are protests and are really yucky.

7.      Fungus: an organism that absorbs food from the surface it lives on.

Athlete’s foot is caused by a fungus that is easily killed by bleach.

8.      Genus: a group of closely related species.

Humans and apes are in the same genus.

9.      Species: a group of organisms that have the same traits.

Humans are the dominant species on Earth.

10.  Cell wall:  the thick covering of a plant cell made from nonliving fibers.

The cell wall protects the cell and its nucleus.

11.  Nucleus: the cell part that controls activities of other cell parts.

The nucleus is the control center of the cell.

12.  Vacuole: storage sacs in a cell.

The vacuole is the place where a cell stores things like waste.

13.  Cytoplasm: the jelly-like fluid between the cell membrane and nucleus.

The cytoplasm all leaked out of the damaged cell.

14.  Chloroplast: the green cell part that traps sunlight.

Plant leaves are full of chloroplasts that make them look green.

15.  Stomata: openings in a leaf through which gases and water enter and leave.

Plant leaves have stomata on their undersides.

16.  Transpiration: the loss of water through stomata.

Plants lose water through their stomata by the process of transpiration.

17.  Chlorophyll: the green material in plants that absorbs energy from sunlight.

A plant’s chloroplasts are just full of chlorophyll and that’s why they are green.

18.  Photosynthesis: the process by which plants make sugar from sunlight, water, and carbon dioxide.

The chlorophyll in a plants’ chloroplasts make energy by photosynthesis.

19.  Respiration: the process by which cells change sugar and oxygen into carbon dioxide and water, thereby releasing energy.

One kind of respiration is breathing but cells use another kind to make energy.

20. Cell Wall: the thick covering of a plant cell made from nonliving fibers

The cell wall protects everything inside the plant cell.
