Question

use the words in the word bank to label the paramecium, an animal-like protist.

word bank:
anal pore, oral groove, food vacuole, cytoplasm, micronucleus, cilia, macronucleus, cell membrane

1. ______
2. ______
3. ______
4. ______
5. ______
6. ______
7. ______
8. ______

Explanation:

Identify the organism and word bank

Using the Paramecium Anatomy and Protist Structure knowledge points
The diagram shows a Paramecium, a single-celled eukaryotic protist covered in hair-like cilia. The word bank contains:

• anal pore
• oral groove
• food vacuole
• cytoplasm
• micronucleus
• cilia
• macronucleus
• cell membrane

Label the outer structures (24, 27, 31)

Using the Paramecium Anatomy and Protist Structure knowledge points

• 24 points to the hair-like projections covering the outer surface: cilia.
• 27 points to the posterior opening used for waste elimination: anal pore.
• 31 points to the thin outer protective barrier: cell membrane.

Label the internal organelles (25, 26, 28, 29, 30)

Using the Paramecium Anatomy and Protist Structure knowledge points

• 25 points to the larger, bean-shaped nucleus: macronucleus.
• 26 points to the smaller, spherical nucleus near the macronucleus: micronucleus.
• 28 points to a circular digestive organelle: food vacuole.
• 29 points to the indented channel where food enters: oral groove.
• 30 points to the fluid substance filling the cell: cytoplasm.

Answer:

No.	Answer
25	macronucleus
26	micronucleus
27	anal pore
28	food vacuole
29	oral groove
30	cytoplasm
31	cell membrane
