|
Plasma Membrane |
Outer surrounding of the cell that controls the movement of substances in and out of the cell. |
|
|
Microvilli |
Folds of the plasma membrane that increases the surface area to increase absorption and sucretion |
|
|
Nucleus |
Contains DNA molecules and the nucleolus |
|
|
Mitochondria |
Site for production of ATP |
|
|
Centrosome (Centriole) |
Used for the growth of Mitotic Spindle and Microtubule formation |
|
|
Golgi complex |
Modifies proteins RER and transports them after being sorted. |
|
|
Nucleolus |
Assembly site for Ribosomes |
|
|
Nuclear Envelope |
Membrane surrounding the Nucleus |
|
|
Rough Endoplasmic Reticulum |
Processes and transports proteins made in the attached ribosomes |
|
|
Smooth Endoplasmic Reticulum |
Fatty acid and Steroid creation site. Detoxifies toxins |
|
|
Lysosomes |
Digestion and Recycle word out organelles and substances |
|
|
Cytosol |
Fluid that surrounds the organelles |
|
|
What are the 4 stanges of Mitosis |
Prophase Metaphase Anaphase Telophase |
|
|
What is Prophase |
Nucleus and Nucleolus disappear and Chromatid become Chromosomes. Centrioles move to opposite sides of cell and form spindle fibres |
|
|
What is Metaphase |
Chromosomes line up at metaphasal plate and spindle fibres attache to centromeres |
|
|
What is anaphase |
Chromatids of chromosomes split and move to opposite poles |
|
|
What is telophase |
Cell reverses prophase and starts to split causing Cytokinesis which is two identical daughter cells. |
|
|
What does the plasma membrane consist of? |
40% Lipids and 60% Proteins |
|
|
What type of proteins are in the cells membrane |
Integral Proteins which span from the inside to the outside Peripheral proteins which are on one side or the other |
|
|
On which side is Carbohydrates to the cell. |
Always on the outside of the cell membrane |
|
|
Membrane Permiability |
Cell Membranes are selectively permiable |
|
|
What is the lipid bilayer permiable to? |
Small uncharged molecules such as O2, CO2, FA, Steroids and Water |
|
|
What does Ions, Glucose and Amine Acids need to transport into the cell |
Transmembrane proteins that act as Channels |
|
|
What do proteins need to move into the cell? |
Vesicular transports because of their large size |
|
|
What is Isotonic? |
The solubility is the same on both sides |
|
|
What is Hypotonic? |
The solution is less concentrated |
|
|
What is Hypertonic? |
The solution is more concentrated |
|
|
What is Phagocytosis? |
Cell eating, Engulfs a particle |
|
|
What is Pinocytosis? |
Cell Drinking, gulps droplets of the extracellular fluids to absorb nutrients |
|
|
What is exocytosis? |
The expulsion of substances out of the cell. |
|
|
What is the purpose of the microtubles |
Cell Shape and creation of cilia and Flagella. |
