Standards SC. 912. L. 14. 3 Compare and contrast the general structures of plant and animal cells. Compare and contrast the general structures of prokaryotic and eukaryotic cells. SC. 912. L. 14. 2 Relate structure to function for the components of plant and animal cells. Explain the role of cell membranes as a highly selective barrier (passive and active transport). • SC. 912. L. 14. In. 2 Identify the major parts of plant and animal cells, including the cell membrane, nucleus, and cytoplasm, and their basic functions. • SC. 912. L. 14. Su. 2 Recognize that cells have different parts and each has a function. • SC. 912. L. 14. Pa. 1 Match parts of common living things to their functions.

Essential Questions/Big Ideas What are animal cells What are the major components of animal cells

Cells • This is an example of cells as seen through a microscope. • Trillions of these cells are found in the human body. • Most cells can only see them under a microscope. • Egg cells can be seen without a microscope.

Review the Organelles of the Cell

All animals are multicellular and eukaryotic.

Animal cells are made up of different parts.

Click on this image to explore the different parts in an animal cell…

Cell Membrane - forms the outer covering of the cell

Cytoplasm - is a gel-like substance where all the other cell parts are floating inside the cell.

As you are reading the article look for the answers to these questions: • Why is cytoplasm important? • What substance does the article compare cytoplasm to? Learn more about cytoplasm by clicking on the image… • What does cytoplasm help move?

Nucleus - contains DNA and controls the activities of the cell.

Centrioles organize the microtubules during cell division.

Golgi complex (body) - stores and packages cell parts

Endoplasmic Reticulum or ER It is the transport system of the cell The ER functions as a manufacturing and packaging system.

Rough ER • Same types of membranes as smooth ER, but different shape. • A rough ER looks like sheets or disks of bumpy membranes • Rough ER is called rough because it has ribosomes attached to its surface. Comparing Rough and Smooth ER • Same types of membranes as rough ER, but different shape. • The smooth ER looks more like tubes. • The smooth ER acts as a storage organelle. It is important in the creation and storage of lipids and steroids Rough ER is found throughout the cell but the density is higher near the nucleus and the Golgi apparatus.

Lysosomes - sacs that digest cell wastes.

Microtubules - are hollow rods, function primarily as support and shape to the cell.

Mitochondria - cellular respiration and energy Mitochondria is the main energy source of the cell. They are called the power house because energy (ATP) is created here.

What is ATP?

As protein synthesis is very important to the cell, ribosomes are found in large number in all cells. Ribosomes are found floating in the cytoplasm and also are attached to the ER Ribosomes - are made of RNA and proteins, and are sites for protein synthesis

Nucleolus - structure in the nucleus • Dark spot in the nucleus. • Where ribosomes are made.

The Incredible, Edible Cell! Materials Directions Will represent Item needed Golgi Bodies 2 blue or green pieces of fruit roll up Endoplasmic Reticulum Ribosomes 2 red or yellow pieces of fruit roll up • 1. Follow the package directions to mix up batches of Jell-O gelatin mix. Pick a light colored flavor. Every 6 oz package will make up 4 or 5 cells. Add some unflavored Knox gelatin to the Jell-O to make it set up a little stiffer (just regular Jell-O fell apart during our first test). Pour the Jell-O mixture into individual 9 oz Solo brand plastic cups until they are about two-thirds full. Put them into a refrigerator to set. 1 teaspoon of round cake sprinkles • 2. Day Two time to eat! Remove the Jell-O from the plastic cup onto the paper plate Mitochondria 4 hot tamales • 3. Cut the Jell-O in half and remove the top half. Turn over the top and set it on the plate beside the bottom half Vacuoles 4 chocolate covered raisins • 4. Use the spoon to dig out a hole in the bottom half of the Jell-O/Knox cytoplasm. Place the gumball in this hole to represent the nucleus of the cell. 1 Jello/Knox mixture in plastic cup 1 paper plate 1 small Dixie cup full of cell parts (organelle) materials 1 plastic knife 1 plastic spoon • 5. Using the spoon to make spaces and your diagram as a guide, place the other cell parts into the cell. Parts can be put into both the top and bottom half of the Jell-O/Knox cell • 6. Take the top part of the cell and carefully place it on the top. If the cell feels soft, you can put the parts back into the plastic cup, then turn it over onto the paper plate. Then carefully remove the plastic cup. • 7. After reviewing the parts one final time, those students who wish to can feast on their cell.
