Question

cells of other organisms 200x paramecia 1. in this section there is another set of sample cells for you to look at-- take a minute to check them out! construct three comparison statements between these organism samples and the plant and animal cell samples you observed in sections 1 and 2. i need a hint

Explanation:

The organism shown is Paramecia, a unicellular protist.

1. Cell Structure Comparison: Paramecia are single-celled, while plant/animal cells are specialized multicellular components. Paramecia have a pellicle (rigid outer layer) instead of a plant cell wall, and lack the membrane-bound organelle specialization seen in animal/plant cells.
2. Locomotion Comparison: Paramecia use cilia for movement, a structure not present in most mature plant or animal cells.
3. Nutrition Comparison: Paramecia are heterotrophic, using oral grooves to ingest food, unlike autotrophic plant cells that perform photosynthesis, and unlike animal cells that receive nutrients from their surrounding multicellular environment.

Answer:

1. Paramecia are single-celled organisms, while plant and animal cells are specialized cells that make up multicellular organisms; paramecia have a pellicle instead of a plant cell wall, and lack the specialized organelle organization of animal/plant cells.
2. Paramecia use hair-like cilia for locomotion, a structure not found in most mature plant or animal cells.
3. Paramecia are heterotrophic and ingest food via an oral groove, unlike autotrophic plant cells that produce their own food via photosynthesis, and unlike animal cells that obtain nutrients from their organism's circulatory/transport system.
