|
what are the three componants that all cells posses
|
1) the outer plasma membrane
2) the cytoplasm 3) DNA |
|
|
|
what is the difference between organic compounds and inorganic compounds?
|
organic compounds- contain carbon, come from living things
inorganic compounds- dont contain carbon (with some exceptions) dont come from living things |
watch organic or inorganic identification video by doug wilhelm on youtube.
|
|
|
Is glass organic or inorganic?
|
inorganic. does not come from a living thing, does not contain carbon
|
glass comes from sand, sand comes from rocks, rocks are non-living
|
|
|
glucose (C6H12O6) organic or inorganic?
|
glucose is a fancy name for sugar, sugar comes from plant, plant is a living thing= organic
contains carbon= organic |
|
|
|
what are the main characteristics of living things
|
movement
respiration sensitivity growth reproduction exretion nutrition |

|
what is a nucleous
|
membrane bound structure that contains chromosomes which consists of DNA, containing the hereditary information and instructions for cell growth, development and reproduction
|
most prominant organell
|
|
|
what organell is responsible for cell reproduction, development and growth
|
the nucleous
|
|
|
|
what is the nucleolis?
|
acts like a ribasome factory, responsible for manufacturing the ribosomal subunits by transcribing DNA into 3 mature RNA's (mRNA) and packaging it together with specific proteins before transporting the subunits out into the cytoplasm.
|
ribasome factory
|
|
|
what is the most prominant organell in the nucleous?
|
the nucleolis
|
|
|
|
what organelle is responsible for transcribing DNA into 3 mRNA's and packaging them with proteins before sending them to the cytoplasm
|
the nucleolis
|
|
|
|
what are ribosomes?
|
small organelles found in the cells of all living things. made up of two smaller subunits.
|
|
|
|
what is the roles of ribasomes
|
produce a variety of proteins from simple genetic instructions. when it is time for the ribasomes to make a protein, the two subunits combine with the messanger RNA (mRNA) and start the protein synthesis.
|
|
|
|
what cells are ribasomes found in.
|
both prokaryotes and eukaryotes
|
|
|
|
what part of the cell is ribasomes found in?
|
in the cytasol or endoplasmic reticulum
|
|
|
|
how many subunits make up a ribasome in a eukaryotes cell?
|
60-s/ 40-s
|
|
|
|
how many subunits make up a ribasome in a prokaryotic cell?
|
50-s/30-s
|
|
|
|
what is the plasma membrane, what is it made of?
|
the outer membrane of a cell that is made up of 2 layers of phospholipids with embedded proteins.
|
|
|
|
what is the plasma membrane responsible for?
|
seperates contents of cell from outside environment amd regulates what enteres the cell.
|
|
|
|
what is cytoplasm
|
the thick solution that fills each cell composed of predomenantly water, salts and proteins.
|
|
|
|
what is the role of cytoplasm
|
it uses its enzymes to break down glucose into pyruvate molecules so that they can be passed on to the mitochondria. because mitochondra cannot use glucose as fuel.
|
|
|
|
what is the mitochondria responsible for
|
acts like a digestive system. takes in nutrience, breaks them down, and creates energy rich molecules for the cell. untimatly they are responsible for keeping the cell full of energy
|
|
|
|
where are mitochondrias found?
|
floating freely
|
|
|
|
how many mitochondrias are in each cell. give an example.
|
anywhere from only a few to several thousand depending on the needs of the cell. muscle cells need alot of energy, therfor they have loads
