Instructions

*DO NOT
add information to this page until this evening. NO ONE should edit this page in class.

1) Your class is going to create a cell.

2) Each of you have been assigned a particular part of a eukaryotic cell.

3) Research and collect information regarding the following:
-what your part looks like
-what it does for the cell
-the size of your part
-pictures and links to websites about your cell part

4) DO NOT add your information to this page until this evening. NO ONE should edit this page in class.

Homework: Insert the information you collected regarding your organelle onto this webpage. I will be checking your work tonight and grading you on the quality of the information you have provided your classmates.

This is also a class competition! May the best cell win!

Resha - Cilia
Cooper - Nucleus:A nucleus only exists in a eukaryotic cell. There is only one nucleus to a eukaryotic cell, where it acts as the "brain." It is the biggest cell organ of the cell with a circular shape, and is protected by a membrane called the "nuclear envelope" which allows only select materials into the "brain." The Nucleus plays the lead role in the cell because at the center of the "brain" there is the nucleolus, which is home to the DNA of a cell. (This is responsible for the production of protein and contains the genetic code for reproduction of the cell.)

Jake - Plasma membrane
The plasma membrane is the cell’s barrier to the outside environment. It also serves as the cell’s boundary, keeping its contents together. The plasma membrane is made up of a bilayer of lipids. These are phospholipids and arrange themselves in a wall with the water fearing tails on the inside. It is basically the outside of the cell.The Plasma membrane can only as big as the cell. This link below provided a great picture and info:
Graham - Cytoskeleton
The cytoskeleton is composed of three different parts. The microfilaments, microtubules, and intermediate filaments make up the cytoskeleton. The microtubules move organelles around the cell. The function of a cytoskeleton is to maintain the shape of the cell. The cytoskeleton also acts in multiple ways, one as a muscle and also as a skeleton. The cells main functions are to provide shape, support and movement. The cells receive vesicles from the Golgi and transport them throughout the cell. It helps move particles into the cell and it also helps move liquid into the cell.

Ali - Endoplasmic reticulum
Endoplasmic reticulum is a network of tubules, vesicles and sacs that are interconnected. The endoplasmic reticulum is responsible for the production of the protein and lipid components of most of the cell's organelles. There are two types of Endoplasmic Reticulum: a rough (ER), and a smooth (ER.) They both have the same types of membranes but they have different shapes, and the rough ER has ribosomes attached. The smooth ER acts as a storage organelle and the rough ER is like a packaging system.

Peter - Chloroplast

Peter

Chloroplast =
Chloroplast is a complex, discrete green structure, or organelle, contained in the cytoplasm of plant cells. Chloroplasts are responsible for the green color of almost all plants and are lacking only in plants that do not make their own food, such as fungi. The chloroplast is generally flattened and lens-shaped and consists of a body, in which are embedded from a few to as many as 50 submicroscopic bodies. The chloroplast contains chlorophyll pigments. Chloroplasts are thus the central site of the photosynthetic process in plants. (Link).
chloroplast - an elongated or disc-shaped organelle containing chlorophyll. Photosynthesis (in which energy from sunlight is converted into chemical energy - food) takes place in the chloroplasts.(Link)
Check Out this LINK for a slideshow of the parts of Chloroplast.
This Link has a picture of where the chloroplast is in the cell.

Alex - Lysosome
Lysosomes act as the cell's digestive sytstem. They digest food particles, from single proteins to complete microorganisms. Lysosme recognizes food vacuoles and fuses with them creating one package surrounded by the lysosome membrane. The enzymes packed into the lysosome digest the bigger molecules such as proteins, fats and carbohydrates in the food contained in its sub-units. The simpler, smaller molecules, amino acids, monosaccharides, and fatty acids which were the product of the digestion fuse out of the lysosome's membrane and into the cytoplasm to nourish the cell. Lysosomes are very important because they convert food into usable energy for the cell. Lysosomes are spherica, though their size and shape may vary.

Codie - Ribosomes
Shape - Ribosomes are roughly spherical and are typically composed of two subunits: a large subunit and a small subunit.
Function - They assemble proteins of the cell and use genetic intructions transported in ribonucleic acid [RNA] to link a specific sequence of amino acids into chains to form proteins.
Size - Ribosomes are ~20 nm [nanometers.] They are made up of 50 proteins and several long RNA strands bound together.

Rachel S - Mitochondria

Information
  • The mitochondria of a eukaryotic cell is used to make energy out of food.
  • There is usually more than one mitochondria in eukaryotic cells.
  • They provide energy for the cell to move, divide, contract… etc.
  • They are the power center of the cell
  • They have their own two membranes around them.

Meredith - Golgi apparatus
The Golgi apparatus is involved in the glycosylation and proteolytic processing of proteins. It is usually referred to the distribution and shipping department for the cell. The primary function of the Golgi apparatus is to pack and process the macromolecules such as proteins and lipids. It also modifies chemicals to help make them functional and stores chemicals. The Golgi is made up of 5-8 cup shaped membrane-covered sacs called cisternae. This cell is relatively large and is usually located close to the nucleus.

Kristen - Vacuole
The vacuoles are in both animal and plant cells. They differ from size and normally in animal cells vacuoles are smaller and in plant cells they are large. Vacuoles play a role in digestion and storage.
