1-1 Flashcards
C’est quoi les caractéristiques des cellules?
Ils réagissent à leur environment et le stimulus
Ils on besoins de l’energie
Ils croissent
Ils reproduisent
Ils éliment les déchets
La théorie cellulaire
La cellule est unité de base
Tous les cellules proviennent d’autres cellules
Tous les organismes sont formé des cellules.
2 sections des organismes basée sur la nombres des cellules
Procaryotes (1 cellule), pas de noyau
Eucaryotes (2+ cellules)
Procaryotes
1 cellule
Eucaryotes
2+ cellules
2 types de cellules basee de function
Vegetales
Animales
Vegetales vs Animales
Vegetales:
+Chloropaste
+Paroi cell.
+Bigger vaccuole (trash can)
Still have membrane cellulaire and mitochondrie
Chloropaste
Photosynthesis for plantes
Mitochondrie
Respiration cellulaire for animales and plantes
Paroi cellulaire
Barrier for plantes on the outside of the plants why wood hard
Cytoplasme
Takes up most of the inside of the cell, made of water and stuff neccesary for life
Vésicules
Made from the membrane of the reticulum endoplasmique rugeux pinching off, they transport proteins to mature in the app. golgi.
App. Golgi
Adds lipides and glucides to polypeptide chains made by ribosomes, maturing them.
Sends various proteins from the ER to various places.
ADN
la recette pour fabriquer les acides aminés, et ensuite les protéines.
ARN meaning
Copies of the ADN that exits from the nucléear pores to the ribosomes. Acide ribonucleique
How do the ribosomes form polypeptide chains?
ARN, copies of ADN from the noyau get transported to a ribosome, which then makes polypeptide chains by adding animo acids based on the structure of the ARM, essentially “decoding” the ARN.
What heppens to the ARN after it gets “decoded” by a ribosome?
The ARN gets degraded.
What happens to the polypeptide chain made by the ribosome after decoding?
It gets transported by a vesicule to the rough RE (reticulum endoplasmique rugeux)
What happens when the polypeptide chain breaks off the ER?
The pinching of the membrane forms a vésicule which transports it to the app. golgi.
Lysosome
Digestive place, not to be mistaken by vacuole.
Vacuole
Bigger in plants, the garbage can
Respiration cellulaire
Glucose + Oxygène -> dioxyde de carbone + eau + energie utilisable
Photosynthesis
Energie par soliel + dioxyde de carbone + eau = Glucose + Oxygène
3 types de bactérie
Coccus
Bacilles
Spirilles
What do you use to destroy bacteria?
Antibiotique
What does antibiotique do?
Either deletes membrane of bacteria or deletes reproductivity of bacteria
How virus work:
Inject DNA, hack cell, reproduce itself, explode cell.
What delete virus?
Anticorps by B-cells (immune system)
What help destroy virus
Vaccins stimules les anticorps
What do vaccins do?
Make anticorps stimule by inserting fake dead virus to make immune system remember it
