17
Q

What are three main differences between prokaryotic and eukaryotic cells

A
  • Prokaryotes lack a nucleus; Eukaryotes have a nucleus
  • Prokaryotic cells lack membrane-bound organelles; eukaryotic cells contain membrane-bound organelles
  • Prokaryotic cells are small and simple; eukaryotic cells are large and complex
18
Q

List three layers from innermost to outermost of a prokaryotic cell

A
  • Plasma Membrane
  • Cell Wall
  • Cell Capsule (Glycocalyx)
19
Q

List some of the external appendage structures that a prokaryotic cell is likely to have (3)

A
  • Flagella: Tail like
  • Fimbriae: Short hairs
  • Sex pill
20
Q

Which eukaryotic organelles could have evolved from prokaryotes that took up residence in early eukaryotic cells (2)

A
  • Chloroplasts
  • Mitochondria
21
Q

How do the nucleus and ribosomes work together?

A

Nucleus provides instructions to the ribosomes for how to build a specific protein

22
Q

How do the ribosomes and endoplasmic reticulum work together?

A

Ribosomes assemble the amino acid sequence of the protein and the endoplasmic reticulum helps make the protein’s shape and transports it

23
Q

How do the endoplasmic reticulum and Golgi apparatus work together?

A

Endoplasmic reticulum packages the produced protein into a vesicle and sends it to the Golgi apparatus to be modified, sorted, and delivered to its final destination

24
Q

How do the Golgi apparatus and vesicles work together?

A

Golgi apparatus receives proteins in vesicles and sends out completed proteins in new vesicles to deliver the protein to its final destination

25
Q

The Rough ER…

A

Synthesizes proteins and packages them in vesicles

26
Q

The Smooth ER…

A

Synthesizes lipids/Detoxify substances

27
Q

Lysosomes…

A

Contain digestive enzymes

28
Q

Vesicles…

A

Transports proteins and lipids to various locations

29
Q

Golgi apparatus…

A

Sorts lipids and proteins and packages them in vesicles

30
Q

Plasma membrane…

A

Flexible boundary that regulates what can enter or exit the cell

31
Q

Without ribosomes, what would a cell be unable to do?

A

Produce Proteins

32
Q

Without mitochondria, what would a cell be unable to do?

A

Breakdown food to produce ATP

A

Endoplasmic reticulum

37
Q

Plant cells…
- Have a cell wall but not a plasma membrane
- Have chloroplasts but no mitochondria
- Do not have any centrioles and yet divide
- Have a large central vacuole but do not have endoplasmic reticulum

A

Do not have any centrioles and yet divide

38
Q

How are mitochondria like chloroplasts?
- They have the same structure.
- They both absorb the energy of the sun.
- They are both transformers of energy.
- They are both in animal cells.

A

They are both transformers of energy.

39
Q

Which organelle is used to produce steroid hormones and to detoxify drugs?
- Lysosomes
- Golgi apparatus
- Rough ER
- Smooth ER

A

Smooth ER
