4. list the 5 characteristics of living things:

a. ________
b. ________
c. ________
d. ________
e. ________

1. the ________ is the part of a cell that controls al other parts.
2. the cell parts that help the cell store and use energy are the ________.
3. ______ cells must be able to stretch while nerve cells are long and ______.
4. the more complicated the animal is, the more ______ ______ it has.
5. how do animals and plants differ in how they get their food?
6. why would it be hard for most animals to survive fi they could not move around?

Explanation:

1. Humans are classified as animals in biological terms.
2. Caterpillars have a large number of small muscles compared to humans.
3. Chloroplasts are the organelles in plant cells responsible for photosynthesis (making food).
4. The five characteristics of living things are: made of cells, obtain and use energy, grow and develop, reproduce, respond to stimuli.
5. The nucleus controls all other parts of the cell.
6. Mitochondria (for energy release) and chloroplasts (in plants for energy storage via photosynthesis) are involved in energy storage and use.
7. Muscle cells must be able to stretch, and nerve cells are long and thin.
8. The more complicated the animal, the more cell types it has.
9. Plants make their own food through photosynthesis, while animals obtain food by consuming other organisms.
10. Most animals need to move to find food, water, mates, and escape from predators.
