5.
b. answer the following questions on the lines below. if you need help, look at the chart on page 65 of your textbook.

1. why is a mushroom not considered a plant?
2. how are bacteria different from protozoa?
3. why can human bodies not make their own food using sunlight?

critical thinking
why would grouping organisms into kingdoms based on size not be a good idea? write your answer on a separate sheet of paper.

Explanation:

1. Bacteria are single - celled prokaryotes and belong to the Monera kingdom.
2. Amoeba is a single - celled eukaryote (protozoa) and belongs to the Protista kingdom.
3. Mushroom is a fungus and belongs to the Fungi kingdom.
4. Fox is an animal and belongs to the Animalia kingdom.
5. The plant in the picture belongs to the Plantae kingdom.
6. Mushrooms do not have chlorophyll (unlike plants) and cannot perform photosynthesis. They obtain nutrients by decomposing organic matter (heterotrophic by absorption, while plants are autotrophic via photosynthesis).
7. Bacteria are prokaryotes (lack a true nucleus and membrane - bound organelles), while protozoa are eukaryotes (have a true nucleus and membrane - bound organelles).
8. Human bodies (like all animals) do not have chloroplasts (the organelle where photosynthesis occurs in plants).

Answer:

1. Monera
2. Protista
3. Fungi
4. Animalia
5. Plantae
6. Mushrooms lack chlorophyll and cannot photosynthesize (unlike plants).
7. Bacteria are prokaryotes; protozoa are eukaryotes.
8. Human bodies lack chloroplasts (needed for photosynthesis).
