1.1.1 Cell Structure

• What is the basic structural and functional unit of all known living organisms?

  Cell
• Which organelle generates energy through respiration?

  Mitochondria
• What is an example of a prokaryotic cell?

  Bacteria
• A cell wall is present in all types of eukaryotic cells.

  False
• Eukaryotic cells have a membrane-bound nucleus that protects their DNA.


  True
• Prokaryotic cells contain organelles.

  False
• Eukaryotic cells have a nucleus.


  True
• What is the smallest unit capable of independently replicating and carrying out biological processes essential for life?

  Cell
• What is an example of a prokaryotic cell?

  Bacteria
• Steps in the process of comparing prokaryotic and eukaryotic cell structures

  1️⃣ Identify key features of prokaryotic cells

  2️⃣ Identify key features of eukaryotic cells

  3️⃣ Compare similarities

  4️⃣ Compare differences
• What is the role of the complex cytoplasm in eukaryotic cells?

  Essential for cell functions
• Eukaryotic cells contain membrane-bound organelles with specialized functions.


  True
• Mitochondria generate energy for the cell through a process called cellular respiration
• The nucleus is responsible for modifying and packaging proteins.

  False
• What are the two main functions of the cell membrane?

  Controlling movement and providing structure
• Cells are essential because they perform all biological functions such as metabolism, growth, and reproduction.


  True
• Prokaryotic and eukaryotic cells are the two primary types of cells
• What is a key feature of eukaryotic cells?

  Membrane-bound nucleus
• What is the term for chemical processes that provide energy and building blocks in a cell?

  Metabolism
• Which organelle in eukaryotic cells modifies and packages proteins?

  Golgi apparatus
• Prokaryotic cell DNA is circular and not enclosed
• The cytoplasm in eukaryotic cells is more complex
• Metabolism refers to chemical processes that provide energy and building blocks
• Eukaryotic cells contain membrane-bound organelles.


  True
• The membrane-bound nucleus in eukaryotic cells encloses and protects DNA.


  True
• What is the primary difference between prokaryotic and eukaryotic cells regarding the nucleus?

  Prokaryotic cells lack a nucleus
• Order the following cellular components from simplest to most complex structure:

  1️⃣ Simple cytoplasm

  2️⃣ Circular DNA

  3️⃣ Membrane-bound organelles

  4️⃣ Linear DNA in nucleus
• All eukaryotic cells have a cell wall.

  False
• What is the function of the Golgi Apparatus in eukaryotic cells?

  Modifies and packages proteins
• What structural feature is present in plant cells but absent in animal cells?

  Cell wall
• The cell membrane is composed of a single layer of phospholipid molecules.

  False
• What does the term "selective permeability" refer to in the context of the cell membrane?

  Allows only certain substances
• Match the cellular structure with its function:

  Cell Membrane ↔️ Controls substance movement

  Cytoplasm ↔️ Contains all cell organelles

  Nucleus ↔️ Protects DNA

  Mitochondria ↔️ Generates energy
• Prokaryotic cells have a membrane-bound nucleus.

  False
• Prokaryotic cells are smaller than eukaryotic cells.
• Steps to describe the structure of prokaryotic cells

  1️⃣ No Nucleus

  2️⃣ No Organelles

  3️⃣ Simple Cytoplasm

  4️⃣ Naked DNA
• Prokaryotic cells lack a nucleus
• All cells have a cell wall.

  False
• Prokaryotic cells are larger than eukaryotic cells.

  False
• Prokaryotic cells do not have a membrane-bound nucleus
