What is one of the distinctive characteristics of eukaryotic cells compared to prokaryotic cells?
What is one of the distinctive characteristics of eukaryotic cells compared to prokaryotic cells?
- Smaller size
- Lack of compartmentation (cell organelles)
- Presence of peptidoglycan in the cell wall
- Presence of a membrane-delimited nucleus (correct)
What is the main function of the plant cell wall?
What is the main function of the plant cell wall?
- Synthesis of signal molecules
- Mechanical support for the cell (correct)
- Regulation of cellular pH
- Energy storage for the cell
Why do plants not use an animal-type skeleton (shell or bones) for structural support?
Why do plants not use an animal-type skeleton (shell or bones) for structural support?
- Cellulose and lignin are more readily available in the environment
- Calcium carbonate tends to alter the cellular pH (correct)
- Animal-type skeletons are too heavy for plant structures
- Calcium phosphate requires high levels of phosphate in the soil

Study Notes
Characteristics of Eukaryotic Cells
- Eukaryotic cells have a true nucleus, bound by a double membrane, which distinguishes them from prokaryotic cells.
Plant Cell Wall Function
- The primary function of the plant cell wall is to provide structural support and protection.
Plant Structural Support
- Plants do not use an animal-type skeleton (shell or bones) for structural support because they have evolved to use their cell walls to provide mechanical strength.
Mechanical Strength in Plant Structures
- Cellulose is the primary component responsible for providing mechanical strength to plant structures.
Multicellular Organisms
- The presence of multiple cells with different structures and functions allows a multicellular organism to have several specialized cell types, each adapted for different tasks.
