Lecture 9

Question 1

Compare and Contrast Prokaryotes and Eukaryotes

Question 2

Typical Animal Cell

Answer 2

-The endoplasmic reticulum (ER) is involved in the synthesis of proteins and lipids.
-The Golgi apparatus modifies proteins and lipids produced by the ER and acts as a sorting station as these molecules move to their final destinations.
-Lysosomes contain enzymes that break down macromolecules such as proteins, nucleic acids, lipids, and complex carbohydrates.
-Mitochondria are specialized organelles that harness energy for the cell.
-The cytoskeleton is a protein scaffold that provides the cell structure.

Question 3

Typical Animal Cell

Answer 3

-A cell wall is present in plant cells—it provides additional support to the cell.
-Vacuoles also contribute to the structure of the cell by maintaining turgor pressure.
- Chloroplasts convert the energy from sunlight into chemical energy the cell can use.
-The entire contents of the cell minus the nucleus make up the cytoplasm.
-The region outside the organelles but inside the plasma membrane is the cytosol.
