Chapter 3 The Plant Cell
________________________________________________________________________________________
I. Introduction to eukaryotic cells - Organelles of the Endomembrane system
A. Nucleus - genetic control center
1. chromatin
2. chromosomes
3. nuclear envelope
4. nucleolus
B. Endomembrane system - organelles enclosed in membranes
1. many organelles work together
2. endoplasmic reticulum
C. Endoplasmic reticulum
Continuous membrane constitutes:
1. rough er
2. smooth er
C. Golgi apparatus - close partner to ER
1. receives and modifies substances
2. substances sent to correct destination
D. Lysosomes
1. produced by ER and Golgi apparatus
2. consists of digestive enzymes
E. Vacuoles function in genl maintenance
1. large lysosome
2. aid in growth
3. store vital chemicals
4. water balance
II. Organelles that convert energy
A. Chloroplasts
1. stroma
2. granum
3. inner and outer membrane
4. 3 compartments for chemical work
B. Mitochondria - convert chemical energy
1. ATP main currency of all work in cell
III. Cytoskeleton
A. Microfilaments
B. Intermediate filaments
C. Microtubules -straight hollow tubes composed of globular proteins
IV. Cilia and flagella move when microtubules bend
A. Cilia - short numerous appendages
B. Flagella - longer less numerous for propulsion
V. Cell Surfaces and Junctions
A. Cell walls in plants 10 - 100x thicker than plasma membranes
1. cellulose embedded
2. several layers
B. Cell junctions connect one cell to another
1. Plasmodesmata in plants
VI. Mitosis vs. Meiosis
VII. Diffusion
Hypotonic
Hypertonic
Isotonic
Plant cells vs. animal cells in various solutions

Lesson Objective Ch. 3
1. Draw a plant cell, label all organelles and give functions for each.
2. Distinguish between eukaryotic and prokaryotic cells.
3. Discuss the advantages of the endomembrane system in eukaryotic cells.
4. Draw and label the conditions of plant vs. animal cells that are placed into hypertonic solutions, hypotonic solutions, and isotonic solutions.
5. Contrast mitosis with meiosis.
