Cell Structure and Function Concepts

The video tutorial guides viewers through drawing and labeling a liver cell, covering key structures such as the cell membrane, nucleus, nucleolus, microvilli, mitochondria, rough and smooth endoplasmic reticulum, Golgi apparatus, and ribosomes. The instructor emphasizes the importance of accurately depicting these components and provides tips for labeling and understanding their functions within the cell.

What is the first step in drawing a liver cell?

• Drawing the nucleus

• Drawing the cell body

• Labeling the cell membrane

• Drawing the mitochondria

Which structure is labeled as the 'nucleolus' in a liver cell?

• The black body in the nucleus

• The microvilli

• The nuclear membrane

• The cell membrane

What are the projections at the top of the liver cell called?

• Golgi apparatus

• Ribosomes

• Microvilli

• Nuclear pores

What is the significance of the folds in the mitochondria's inner membrane?

• They are used for cell communication.

• They are called cristae and increase surface area for energy production.

• They protect the mitochondria from damage.

• They store genetic material.

What distinguishes the rough endoplasmic reticulum from the smooth endoplasmic reticulum?

• Its role in lipid synthesis

• Its ability to store calcium

• Its proximity to the nucleus

• Presence of ribosomes on its surface

What is the function of ribosomes attached to the rough endoplasmic reticulum?

• Cell division

• DNA replication

• Protein synthesis

• Lipid synthesis

What does the Golgi apparatus resemble in its structure?

• A stack of pancakes

• A spiral staircase

• A honeycomb

• A flat sheet

Where is the Golgi apparatus typically located in relation to the endoplasmic reticulum?

• Inside the nucleus

• Closer to the nucleus

• Adjacent to the cell membrane

• Further out from the endoplasmic reticulum

What is the primary component of the cytoplasm?

• Carbohydrates

• Water

• Proteins

• Lipids

What is the difference between ribosomes in eukaryotes and prokaryotes?

• There is no difference between them.

• Eukaryotic ribosomes are 70S, while prokaryotic ribosomes are 80S.

• Eukaryotic ribosomes are larger than prokaryotic ribosomes.

• Eukaryotic ribosomes are 80S, while prokaryotic ribosomes are 70S.
