Prokaryotic & Eukaryotic Cells (PPT 1-4) [U1/ T1]

Question 1

What are the common cell requirements

Answer 1

• Energy (Glucose)
• Nutrients
• Gases (e.g. carbon dioxide & oxygen)
• Removal of wastes

Question 2

What are the 4 major macromolecules?

Answer 2

• Carbohydrates
• Protein
• Lipids
• Nucleic acids

Question 3

What is the cell theory?

Answer 3

• The cell is the fundamental structure of all life.
• All cells come from pre-existing cells
• All cells have the same basic chemical function.

Question 4

What are the common cell structures?

Answer 4

• Plasma membrane
• Contain cytoplasm
• Contain ribosomes
• Contain DNA

Question 5

What features are common to all Eukaryotic cells?

Answer 5

• They are larger than prokaryotic
• Major internal compartmentalization
• DNA is held in true nucelous
• Membrane bound organelles
• More efficient than prokaryotic

Question 6

What features are common to all Prokaryotic cells?

Answer 6

• Very small
• Lack internal compartmentalization
• No true nucleous
• No internal membrane bound organelles

Question 7

What features are common to all cells?

Prokaryotic & Eukaryotic

Answer 7

• Contain DNA
• Have cytoplasm
• Have a cell membrane
• Contain ribosomes
• Need nutrients
• Neutral pH
• Removal of toxins & wastes

Question 8

What are the biochemical processers controlled by these organelles?

1) Chloroplasts
2) Mitochondria
3) Rough Endoplasmic Reticulum

Answer 8

1) Chloroplasts = Photosynthesis
2) Mitochondria = Cellular Respiration
3) Rough Endoplasmic Reticulum = Synthesis of proteins

Question 9

What are the biochemical processers controlled by these organelles? {2}

4) Smooth Endoplasmic Reticulum
5) Plastids
6) Lysosomes

Answer 9

4) Smooth Endoplasmic Reticulum = Synthesis of carbohydrates, lipids & steroids
5) Plastids = Synthesis of pigments, tannins & polyphenols
6) Lysosomes = Removal of cellular products & wastes
