Monday Night... Unit 4: Cell Structure and Function Content Outline: Types of Cells and Cell Structures (4.1) – Part
2
I. Eukaryotic Cells have many structures called organelles - membrane bound structures that have specialized functions
II. Nucleus .... acts as a “control center” for all activities performed by the cell.
Stores genetic information (DNA).
A. Nuclear Envelope/Membrane (This acts as the actual “vault” to protect the DNA that is inside.)
1. Contains pores (tunnels) for molecules to travel through.
2. The messenger RNA leaves to help make proteins in the cytoplasmic “construction site”.
C. DNA (The “instructions” for all cell’s activities, genetic material)
1. Chromatin phase “The DNA is loose” (It would look like a bowl of plain spaghetti noodles.) “Working form” DNA genes
can be read to build proteins
2. Chromosome phase “The DNA is tightly wrapped up.” Phase is used for separating the DNA equally during cell division.
D. Nucleolus
Responsible for helping to make Ribosomes, which are mostly RNA structures.
Eukaryotic Cell
Prokaryotic Cell
Compare and Contrast these cells!
Tuesday Night.... Unit 4: Cell Structure and Function Content Outline: Types of Cells and Cell Structures (4.1) – Part 3
I. Ribosomes
A. These are cellular particles made of RNA and proteins. (Not organelles… all cell types have them so that all cells can make
proteins and enzymes.)
B. Sites of Protein Synthesis/Production.
C. Found on Endoplasmic Reticulum (Rough) or in cytoplasm.
II. Endoplasmic Reticulum (ER)
A. It is composed of a network of small tubes called cisternae.... for transport of proteins... “subway system”
B. They are always found just outside and around the nucleus.
C. Two types of ER can exist inside Eukaryotic cells:
1. Smooth Endoplasmic Reticulum (SER)
helps with the synthesis of lipids, phospholipids, and steroids.
2. Rough Endoplasmic Reticulum (RER)
protein synthesis. Ribosomes are bound to the outside of the organelle and they
deposit the protein inside as it is made by the ribosome.
III. Golgi Apparatus modifies proteins ... “FedEx Packers”
A. It is like “Gift Wrapping” to prepare the protein for export through the cell membrane.
B. They are also composed of flattened tubes also called cisternae (These look like a stack of pancakes.)
Wednesday Night....Unit 4: Cell Structure and Function Content Outline: Types of Cells and Cell Structures (4.1) – Part 4
I. Lysosomes ... “Cleanup Crew”
A. They are involved in digestion and recycling of cell materials
B. They are full of digestive enzymes. (Lysozyme is the name of the enzyme.)
II. Vacuoles “storage tanks”
A. Storage structures for various products needed by the cell... in particular food, water and waste
B. Plant cells have large vacuoles.... They store water to help keep plants upright and sturdy.
III. Vesicles ... “bubbles filled with materials”
A. Used to transport materials around and in and out of the cell.
B. They are formed from the membranes of the Endoplasmic Reticulum or Golgi apparatus.
IV. Mitochondria (Nicknamed the “Power House”)
A. This organelle is involved in making energy by performing the process of Cellular Respiration
1. Cellular Respiration is the process of using glucose and oxygen and creating carbon dioxide, water and ATP energy.
B. Depending on the cell function, some cells have more mitochondria (ex: muscle cells in legs).
Thursday Night....Unit 4: Cell Structure and Function Content Outline: Types of Cells and Cell Structures (4.1) – Part 5
I. Chloroplasts
A. These organelles are the site of photosynthesis in plants and algae
1. Photosynthesis is the process that plants use to produce sugar (food) from water, CO 2 and sunlight energy.
B. These contain the protein pigments chlorophyll. (“chloro” means green and “phyll” means pigment
1. The chlorophyll collects the sun’s energy during the day to power photosynthesis.
II. Cytoskeleton
A. This structure helps support and protect the cell.
B. Assists in cell mobility or cell organelle movement.
C. The cytoskeleton is composed of various sized protein fibers (Your skeleton has different sized structures too. (Largest – bones,
middle – Ligament and tendons, smallest- muscle fibers)
1. Microtubules (largest) ...Main function is cell support or movement. also guide supports for organelle movement
2. Microfilaments (Smallest structures in the cytoskeleton.) Provide a pulling force. Abundant in muscle tissue.
3. Intermediate Filaments (medium sized )(“inter” means “between”) help to reinforce and brace the large microtubules.
III.
Cell Wall (In plants)
A. Plant cells create this structure for protection and durability. (Basically, to maintain shape and structure.)
B. Composed of Cellulose (Found in all plant cells.)
Practice Quiz!
Match the cell part with its job:
_____ Powerhouse of the cell, ATP energy made here
using aerobic cellular respiration
a. lysosomes
_____ Photosynthesis occurs here
b. nucleus
_____ Transport system of the cell and a site for manufacturing,
ribosomes are sometimes found here
c. cytoplasm
_____ These package proteins for transport out of the cell
d. cell wall
_____ These are the protein factories of the cell
e. chloroplast
_____ These are rod shaped structures made of DNA that pass traits
from one generation to the next. When relaxed called chromatin.
f. ribosome
_____ This is the control center of the cell that directs cellular activities
g. mitochondria
_____ These are very large in plant cells and hold food, water and waste
h. cell membrane
_____ This is the gatekeeper of the cells that regulates what comes in/out
i. vacuoles
_____ This is a rigid, tough structure made of cellulose that protects
and supports plant cells.
j. ER
_____ This is the jelly like material that holds all the organelles.
k. Golgi bodies
_____ Found mainly in animal cells, these are bags of acid that break
down worn out cell parts or invading bacteria.
l. chromosomes
What are the 3 parts of the Cell theory?
Use a T chart to contrast Prokaryotic and Eukaryotic Cells.
Create a Venn Diagram to compare and contrast plant and animal cells.
