1. Objective
SWBAT identify differences in the internal cellular structures of plants and animals, and in how plants and animals get energy.

2. Animal Cells Have a nucleus Have a cell membrane, but no cell wall
Have mitochondria, but do not have chloroplasts.

3. Plant Cells Have a nucleus Have a cell wall outside the cell membrane
Have chloroplasts and mitochondria.

4. Check For Understanding
Which characteristic correctly describes a difference between plant cells and animal cells?
Animal cells have cell membranes, but plant cells do not.
Plant cells have cell membranes, but animal cells do not.
Animal cells have chloroplasts, but plant cells do not.
Plant cells have chloroplasts, but animal cells do not.

5. Cell Wall
Allows plant cells to stand upright, even in the wind  helps them get sunlight.
Not having a cell wall allows animal cells to be more flexible  helps them move to catch prey.

6. Chloroplasts
Plants use chloroplasts to conduct photosynthesis, in which they absorb sunlight and turn it into food. This makes them producers.
Animals don’t need chloroplasts, because they are consumers – they eat food.

7. Check For Understanding
Plant and animal cells share many processes, but there are major differences in their cell structures. Which cell structures exist in plant cells, but not in animal cells?
Vacuoles and cell wall
Cell wall and chloroplasts
Chloroplasts and vacuoles
Cell membrane and mitochondria

8. Chloroplast

9. Check For Understanding
Which difference between plants and animals is illustrated by the food web?
Animals only consume other animals.
Only plants produce their own energy.
Animals are only dependent on plants for energy.
Only animals pass on energy to other organisms.

10. Check For Understanding
Which statement explains why, in a food chain, plants are called producers and animals are called consumers?
Plants make oxygen, and animals use it.
Plants use carbon dioxide, and animals give it off.
Plants make their own food, and animals eat other organisms.
Plants use energy from the soil, and animals make their own food.
