|
What does organelles mean?
|
small organs
|
|
|
What is the plasma membrane?
|
Mechanical barrier of the cell that is selectively permeable
|
|
|
The plasma membrane mediates ____ to _____ interactions which is a ____ actual barrier
|
cell to cell, physical
|
|
|
The cell membranes main functions are?
|
Secretion by exocytosis
|
|
|
The plasma membrane is made of a ____ represented by what model?
|
lipid bilayer, fluid mosaic model
|
|
|
What is the purpose for the cytoplasmic matrix?
|
Houses all of the organelles
|
|
|
The ground substance of the cytoplasmic matrix is what and what is it made of?
|
The cytoplasm (jelly like) with 2/3 water and 1/3 protein
|
|
|
What is the difference between microfilaments and microtubules
|
Microfilaments are smaller and act like a skeletal system, microtubules are larger and act like a highway
|
|
|
What are microtubules used for and how do they work?
|
They are used for transportation and have a 9/2 pairing
|
|
|
What is the 9/2 pairing of microtubules?
|
9 bundles of two forming a circle and are used for cell division
|
|
|
What is the function for the endoplasmic reticulum (both types)?
|
Used for protein synthesis
|
|
|
What are the two types of ER?
|
Rough because of the ribosomes and smooth
|
|
|
What does the rough ER do?
|
The ribosomes in the ER make proteins and then the rough is does protein folding
|
|
|
The smooth ER synthesizes what?
|
Lipids and sterols that the phosolipid bilayer in the cell membrane need
|
|
|
Where is the Rough ER
|
around the nucleus' membrane
|
|
|
For the cells to be transported what must they go through?
|
The trans golgi network, one side to the other
|
|
|
What is the Transgolgi Networks main function?
|
Packages and processes, it is the UPS of a cell
|
|
|
Lysomes are the ____ of the cell and with what metabolism?
|
Digestion with catabolism, breaks things down and gets rid of them
|
|
|
Where is all energy made?
|
In the Mitochondria
|
|
|
What is the Mitochondria?
|
The power house of cells, it provides energy
|
|
|
How many membranes does the mitochondria have and which one is most important?
|
Two, the inner membrane that has the cristae which is where Aerobic Cellular Respiration occurs
|
|
|
Where is the genetic material found?
|
In the Nucleus
|
|
|
What makes up the nucleus?
|
The chromatin which packages the DNA into a cell and makes it strong and prevent damage during mitosis/meoisis
|
|
|
What do Eukaryotic cells have for DNA?
|
Only in Eukaryotic cells is there a nucleus that has chromatin that have its own envelope and pores to regulate what comes in and out
|
|
|
How does cell division occur?
|
The chromatin beings to the centriole of the cell and attaches to microtubules and then divides cells
|
|
|
What allows movement of cells and what are they made of?
|
Cilia and Flagella, made of microfilaments if they are small and microtubules if they are large
|
|
|
What does cilia do?
|
compacts areas into smaller spaces so increase a surface area, helps with absorbtion in the intestines and pushes things out of the lungs
|
|
|
Sperm movement only has ____
|
flagella
|
|
|
Transportation using cell energy to movement in and out is _____?
|
Active transport
|
|
|
Passive transport includes what?
|
Diffusion, Osmosis, Facilitated diffusion and filtration
|
|
|
What is the energy molecule in the body?
|
ATP - Adenosine Triphosphate
|
|
|
Chromatin is found in the nucleus and contains what?
|
DNA
|
|
|
The organelle acting as a power plant and providing 95% of our energy is ____?
|
The mitochondria
|
