Eukaryotic vs Prokaryotic Cells/Cell Structure

Question 1

Describe the cell organelles of Prokaryotes vs Eukaryotes

Answer 1

Prokaryotes: Lack membrane-bound organelles - have simpler structures like ribosomes.

Eukaryotes: Contain membrane bound organelles such as mitochondria, ER, Golgi apparatus, lysosomes etc.

Question 2

Describe the nucleus and DNA arrangement of Prokaryotes vs Eukaryotes

Answer 2

Nucleus:
- Prokaryotes: lack true nucleus - genetic material is present in the nucleoid and not enclosed by a membrane.
- Eukaryotes: Have a true nucleus enclosed by nuclear membrane, containing genetic material (DNA).

DNA arrangement:
- Prokaryotes: single, circular chromosome - may also contain plasmids (Plasmids are physically separate from chromosomal DNA and replicate independently).
- Eukaryotes: Multiple linear chromosomes found in the nucleus.

Question 3

What is the function of the plasma membrane
