Cell Biology I

What is the main function of the cell membrane?

• Maintain cell shape

• Produce energy

• Store genetic information

• Regulate passage of substances

Name three organelles found in a typical animal cell and their functions.

• Nucleus, Mitochondria, Golgi apparatus

• Lysosome - stores waste material, Endoplasmic reticulum - produces lipids, Peroxisome - breaks down fatty acids

Define the term 'tissue' in the context of biology.

• A group of similar cells which come together to perform a specific function.

• A type of molecule found in cells.

• A group of organs working together.

• A single cell that performs a specific function.

Explain the difference between a tissue and an organ.

• A tissue is a type of fabric, while an organ is a part of the body

• A tissue is a type of paper product, while an organ is a musical instrument

• The main difference between a tissue and an organ is that a tissue is made up of a group of cells that work together to perform a specific function, whereas an organ is made up of a group of tissues that work together to perform a specific function.

• A tissue is a type of food, while an organ is a type of plant

How are organ systems different from individual organs?

• Organ systems are smaller in size compared to individual organs.

• Organ systems perform only one function, unlike individual organs.

• Individual organs are always found in pairs, while organ systems are not.

• Organ systems involve multiple organs working together, whereas individual organs are single structures with specific functions.

What is the role of the phospholipid bilayer in the cell membrane?

• Semi-permeable barrier and structural support

• Energy production

• Cell division

• Waste removal

Describe the function of the mitochondria in a cell.

• The mitochondria function to regulate and regulate cellular processes

• The mitochondria function to generate ATP through cellular respiration.

• The mitochondria function to store genetic material

• The mitochondria function to synthesize proteins

What is the function of the Golgi apparatus?

• Stores genetic information

• Produces energy for the cell

• Processes, sorts, and packages proteins and lipids

• Regulates cell division

What are the four main types of tissues found in the human body?

• skin tissue, ligament tissue, cardiac tissue, and brain tissue

• bone tissue, cartilage tissue, blood tissue, and fat tissue

• smooth tissue, rough tissue, striated tissue, and cardiac tissue

• epithelial tissue, connective tissue, muscle tissue, and nervous tissue

Give an example of an organ and explain its function.

• Brain

• Lungs

• Stomach

• Heart
