2.2 Cell Structure and Function

• The cell is considered the basic unit of life because it possesses the ability to obtain and use energy
• Match the cell type with the presence of a nucleus:

  Prokaryotic cell ↔️ Absent

  Eukaryotic cell ↔️ Present
• Eukaryotic cells are simpler than prokaryotic cells.

  False
• Order the reproductive processes in prokaryotic and eukaryotic cells:

  1️⃣ Asexual (binary fission)

  2️⃣ Sexual and asexual (mitosis, meiosis)
• Prokaryotic cells do not have membrane-bound organelles
• Where is the DNA located in eukaryotic cells?

  In the nucleus
• Where is DNA located in a prokaryotic cell?

  Cytoplasm
• Eukaryotic cells have a true nucleus and membrane-bound organelles.


  True
• What is the primary function of mitochondria in a eukaryotic cell?

  Generate ATP
• Chloroplasts are found in animal cells.

  False
• Match the organelle with its function in eukaryotic cells:

  Nucleus ↔️ Controls cell activity

  Mitochondria ↔️ Generates ATP

  Golgi Apparatus ↔️ Processes proteins
• What do chloroplasts in plant cells contain?

  Chlorophyll
• The cell is the smallest structural and functional unit of life.


  True
• What is the typical size range of a eukaryotic cell?

  10-100 μm
• What type of cells contain major organelles with specialized functions?

  Eukaryotic cells
• Which organelle contains the cell's DNA and controls cellular activities?

  Nucleus
• The endoplasmic reticulum is involved in protein and lipid synthesis.


  True
• Ribosomes synthesize proteins from mRNA
• Peroxisomes detoxify harmful substances and break down fatty acids.


  True
• Which organelle in plant cells carries out photosynthesis?

  Chloroplasts
• Animal cells have centrosomes, which are involved in cell division.


  True
• What process occurs in mitochondria to generate ATP?

  Cellular respiration
• Ribosomes synthesize proteins from mRNA templates.


  True
• The Golgi Apparatus processes and packages proteins produced in the ER
• Which organelle generates ATP for the cell?

  Mitochondria
• Why is the cell considered the basic unit of life?

  It is the smallest structural and functional unit
• Prokaryotic cells have a nucleus.

  False
• Where is the DNA located in prokaryotic cells?

  Nucleoid
• Prokaryotic cells are found in bacteria and archaea
• What are the essential characteristics of a cell as the basic unit of life?

  Obtain and use energy, grow, respond to stimuli, and reproduce
• Eukaryotic cells have a true nucleus.


  True
• Match the cell feature with the correct cell type:

  True nucleus ↔️ Eukaryotic

  Nucleoid ↔️ Prokaryotic
• What is the typical size range of a prokaryotic cell?

  0.1-5 μm
• The nucleus contains the cell's DNA and controls cell activity
• Which organelle is involved in protein and lipid synthesis?

  Endoplasmic Reticulum
• The nucleus contains DNA and controls cell activity
• Plant cells have a cell wall made of cellulose.


  True
• Plant cells have a cell wall and chloroplasts, while animal cells lack these structures
• Which type of cell lacks a nucleus?

  Prokaryotic
• What is the function of the nucleus in a eukaryotic cell?

  Controls cellular activities
