Living Systems
A. Parts of a cell:
1.
Plant: use photosynthesis (water and sunlight) to make food
(sugars)
a. Cell wall: outer cell covering that gives the cell
its shape
b. Cell membrane: thin layer around all cells that allows water
and materials in and out of the cell
c. Nucleus: controls the cell's activities
d. Vacuole: storage area for food and wastes
e. Cytoplasm: jellylike substance that fills the cell
f. Chloroplasts: food making part of a plant cell that contains
chlorophyll
2. Animal: can't make their own food, must eat plants or meat
or both, don't have cell walls or chloroplasts
B. Kingdoms
1.
Plant
a. vascular: seeded plants ( e.g., flowers and cones)
b. nonvascular: nonseeded plants (e.g., ferns, liverworts,
horsetails)
2. Animal
a. vertebrates
b. invertebrates
3. Fungi : reproduces using spores (e.g., mushroom, mold, yeast)
4. Moneran: one-celled organisms that do not have a nucleus
(bacteria and blue-green algae)
- Bacteria: monerans that feed on dead matter or living things
(e.g., bacillus, coccus, and spirillum)
Viruses: tinier than monerans (DNA or RNA) wrapped inside a capsule
of protein)
5. Protists: animal like, mostly single-celled organisms (e.g.,
protozoan, algae, diatoms, plankton), many live in water
