Cell Structure and Function Concepts

This video tutorial by Sarah from Registered Nurse RN provides an overview of cell structure and function, essential for anatomy and physiology classes. It covers the main components of a human cell, including the plasma membrane, cytoplasm, and nucleus, and details the functions of various organelles like chromatin, nucleolus, ribosomes, and mitochondria. The video also includes quiz questions to help reinforce learning and prepare for exams.

What is the primary role of the plasma membrane in a cell?

• To act as the outer boundary of the cell

• To control cell activities

• To synthesize proteins

• To generate energy for the cell

Which part of the cell is known as the control center?

• Mitochondria

• Ribosome

• Nucleus

• Cytoplasm

What is the function of chromatin within the cell?

• To produce energy

• To package DNA and control replication

• To synthesize lipids

• To detoxify free radicals

Where are ribosomes primarily found and what is their function?

• In the rough endoplasmic reticulum, synthesizing proteins

• In the nucleus, controlling cell activities

• In the cytoplasm, generating energy

• In the plasma membrane, providing structure

What is the main function of mitochondria in the cell?

• To package DNA

• To act as the control center

• To synthesize proteins

• To generate energy

How do microvilli contribute to cell function?

• By packaging proteins

• By synthesizing lipids

• By increasing surface area

• By detoxifying free radicals

What is the role of the Golgi apparatus in a cell?

• To control cell activities

• To synthesize lipids

• To package and process proteins

• To generate energy

Which organelle is responsible for detoxifying cells from free radicals?

• Nucleus

• Mitochondria

• Peroxisome

• Lysosome

What is the primary function of the rough endoplasmic reticulum?

• To synthesize lipids

• To generate energy

• To control cell activities

• To synthesize proteins

What is the function of the nuclear envelope?

• To regulate passage of substances to and from the nucleus

• To synthesize proteins

• To detoxify free radicals

• To generate energy
