Cell Structure and Function Concepts

This video tutorial covers the structure and organization of eukaryotic cells, focusing on the differences between plant and animal cells. It introduces basic cell components like the nucleus, cytoplasm, and cell membrane, and explores additional organelles visible under light and electron microscopes. The tutorial also includes a practical exercise on labeling 3D cell diagrams and concludes with a summary and preview of the next lesson.

What is the primary difference between eukaryotic and prokaryotic cells?

• Eukaryotic cells have a nucleus, while prokaryotic cells do not.

• Eukaryotic cells are single-celled, while prokaryotic cells are multi-celled.

• Prokaryotic cells have a nucleus, while eukaryotic cells do not.

• Both have a nucleus, but eukaryotic cells are larger.

Which of the following is NOT one of the three main organelles found in all cells?

• Nucleus

• Cell membrane

• Cell wall

• Cytoplasm

What additional structures are found in plant cells but not in animal cells when viewed under a light microscope?

• Nucleus, cytoplasm, and cell membrane

• Centrioles and lysosomes

• Chloroplasts, cell wall, and large central vacuole

• Mitochondria and ribosomes

Which organelle is known for its role in energy production within the cell?

• Golgi apparatus

• Mitochondria

• Smooth endoplasmic reticulum

• Rough endoplasmic reticulum

What is the function of ribosomes in a cell?

• Lipid synthesis

• Protein synthesis

• Energy production

• Photosynthesis

Which organelle is responsible for packaging and modifying proteins?

• Mitochondria

What is the main structural difference between rough and smooth endoplasmic reticulum?

• Both have ribosomes, but rough ER is larger.

• Neither have ribosomes, but rough ER is more folded.

• Smooth ER has ribosomes attached, rough ER does not.

• Rough ER has ribosomes attached, smooth ER does not.

Which organelle is only found in animal cells and not in plant cells?
