Plant and Animal Cells Under the Microscope 1. What indicators were used to help view some organelles under the microscope? 2. What is the structural difference between cheek cells and frog’s blood? How does this affect the function? 3. What structure did plant cells have that animal cells did not? 4. What organelle could be seen in the spinach cells, but not the onion cells? Why?

Prokaryotic Cell Structurally Simpler than Eukaryotic Cells

Eukaryotic Cell: Animal

Eukaryotic: Plant

Cell Membrane (Covered Extensively in Chapter 5)

Nucleus is the cell’s genetic control center

Overview: Many cell organelles are connected through the endomembrane system

Ribosomes make proteins for use in the cell and export Structure: A. Large Subunit B. Small Subunit Function: - Polypeptide (protein) synthesis Location: A. Free: in cytoplasm B. Attached : bound to ER

The endoplasmic reticulum is a biosynthetic factory Structure: Passage ways inside cell Function: A. Rough ER: synthesis of membrane lipids and proteins, secretory proteins, and hydrolytic enzymes; formation of transport vesicles. B. Smooth ER: Lipid synthesis, detoxification in liver cells, calcium ion storage.

Synthesis and packaging of a secretory protein by the rough ER

Golgi apparatus finishes, sorts, and ships cell products

Lysosomes are digestive compartments

Review of structures involved in manufacturing and breakdown

Mitochondria harvest chemical energy from food

Chloroplasts convert solar energy to chemical energy

Mitochondria and chloroplasts evolved by endosymbiosis

Cell wall enclose and support plant cells
