Cell & Organelles Flashcards
(28 cards)
What are the two types of cells found in the human body?
Sex cells and Somatic (body) cells
What is the Cytoplasm?
Is all the materials inside the cell and outside the nucleus
What is the Cytoplasm?
All the material form the plasma membrane to the nucleus, and it’s divided into the cytosol and the organelles
CENTRIOLES
Function during cell division, they’re going to help organize and oversee the process of cellular division
CYTOSKELETON
Lies right underneath the plasma membrane, provides support, structure, and things travel along it
PLASMA MEMBRANE
Is the outer boundary that separates the cell from all the space outside(referred to extracellular space)
MICROVILI
Are little finger like projections that extend off the surface of the cell and Microvili function to increase the surface area for absorption
CILIA
Are finger like projections that extend off the surface of the cell membrane but these projections move so they rhythmically beat and create a current to wash fluid off the surface of the cell
ENDOPLASMIC RETICULUM
U usually very close associated to the nucleus, Can be rough or smooth. They function to synthesize carbs, lipids; rough endoplasmic reticulum also synthesizes proteins
RIBOSOMES
These in two flavors, Fixed Ribosomes synthesize proteins for export; and Free Ribosomes synthesize proteins for the cellular use
MITOCONDRIA
It takes chemical energy and converse it into energy currency that the cell can use MITOCONDRIA
GOLGI APPARATUS or BODY
It’s sort of the shipping and receiving center of the cell. Anytime products are exported out or brought into the cell they encounter the goilgi body, and it modifies and packages products
LYSOSOMES
Organelles that are produced by the Golgi Body(they’re the packages released for intracellular use). Lysosomes are little packets of digestive enzymes, they’re there to help digest and clean up parts of the cell
NUCLEUS
It’s the biggest organelle, contains genetic information, DNA
PLASMA MEMBRANE
Is a barrier, is selectively permeable
CHROMATIN
When the cell is not dividing the DNA is loosely coiled as CHROMATIN in the nucleus
CHROMOSOMES
When the cells is prepared for division the DNA is tightly coiled as CHROMOSOMES in the nucleus
IS A SELECTIVELY PERMEABLE BARRIER, THAT SEPARATES THE CELL FROM ALL THE SPACE OUTSIDE
PLASMA MEMBRANE
OVERSEE jjCELLULAR DIVISION
CENTRIOLES
LIES RIGHT UNDERNEATH THE PLASMA MEMBRANE
CYTOSKELETON
FINGER LIKE PROJECTION THAT FUNCTION TO INCREASE SURFACE AREA TO FACILITATE ABSORPTION BY EXTENDING OFF THE SURFACE OF THE CELL
MICROVILI
FINGER LIKE PROJECTIONS THAT EXTEND OFF THE SURFACE OF THE CELL MEMBRANE, THESE PROJECTIONS FUNCTION TO CREATE A CURRENT IN ORDER TO MOVE FLUID OVE THE SURFACE
CILIA
think of moving mucus
THESE COM IN TWO FLAVORS, FIXED, THESE SYNTHESIZE PROTEINS FOR EXPORT, AND FREE, THEY SYNTHESIZE PROTEINS FOR INTRACELLULAR USE
RIBOSOMES
CAN BE ROUGH OR SMOOTH. THEY CAN SYNTHESIZE CARBS, LIPIDS AND THE ROUGH PART CAN SYNTHESIZE PROTEINS
ENDOPLASMIC RETICULUM
