Eukaryotes Flashcards
What does the plasma membrane do for eukaryotes?
Controls entry/exit of nutrients and waste
What do lysosomes do for eukaryotes?
Contains digestive enzymes for breaking down nutrient molecules and dead cell parts for recycling
What do free ribosomes do for eukaryotes?
Produce proteins to be used by this cell
What does cytoplasm do for eukaryotes?
Contains enzymes and solutes needed for metabolic reactions within the cell as well as dissolving mineral ions, nutrients and waste
What does the rough endoplasmic reticulum (with ribosomes) do for eukaryotes?
Ribosomes on rough ER produce proteins to be exported from the cell
What does the nuclear membrane do for eukaryotes?
Allows things to enter/exit the nucleus
What does the Golgi apparatus do for eukaryotes?
Modules and packages proteins produced in rough ER to be exported by the ell via exocytosis
What does the nucleus do for eukaryotes?
Membrane bound nucleus contains all genetic information in chromosomes. The nucleus is a densely packed area of DNA
What does mitochondria do for eukaryotes?
Site for respiration; converts sugars in ATP
What does the nucleiod do for eukaryotes?
A dense solid structure involved in ribosomes synthesis
Compared to a city what is the plasma membrane
The city wall ~ gate keeper
Compared to a city what is the lysosomes
Garbage people
Compared to a city what is the rough ER with ribosomes
A factory
Compared to a city what is the Golgi apparatus
UPS
Compared to a city what is the nucleus
Town hall
Compared to a city what is the mitochondria
Power house, power plant
Define- eukaryotes
Contain ‘true’ nucleus and membrane bound organelles
Compare prokaryotes and eukaryotes
Prokaryotes-very small Eukaryotes-very big Prokaryotes-bacteria Eukaryotes-cells that make up organisms Prokaryotes-simple Eukaryotes-complex Both have ribosomes and a nucleiod
3 differences between plant and animal cells
1) cell wall vs. cell membrane
2) vacuole
3) lysosomes vs. chloroplasts
What does the vacuole for plant cells
It’s filled with water and sugars that makes up majority of the cell
What is extra cellular components
A barrier between the cell membrane and the cell wall
Two roles for extra cellular components
Glycoproteins surrounds the outside of a animal cell outside of the cell membrane that has a mixture of proteins and sugars
Plant cells have EC components that protects the shape of the cell and provides a filter mechanism to keep cells in order so that they are not too filled with water
What is an extra cellular?
Extra ‘outside’ cellular ‘the cell’
What is the endosymbiont theory?
Smaller unicellular organisms were engulfed and became part of a larger organisms, eventually specializing to become organelles within the cell
