1.2 - Les Cellules Flashcards
C’est quoi la theorie cellule
- La cellule est l’unité de base
- Tous les organismes sont formés des cellules
- Toutes les cellules proviennent d’autres cellules.
What are organisms with one cell called
unicellulaires
What are organisms with two cells called
pluricellulaires
What are cells procaryotes?
Cells without a noyau
(avant le noyau)
C’est quoi les cellules eucaryotes?
Cells with a noyau
(vrai noyau)
Do all cells originate from one base cell back in time?
Yes
C’est quoi le membrane cellulaire?
Elle entoure les organites et protège la cellule et surveille l’entrée et sortie des
substances.
What regulates the
composition du cytoplasme?
Le membrane cellulaire
C’est quoi le cytoplasme?
The liquid that the cells are made of and swim in
How much space does l’organites take up in a cell?
5 - 30%
C’est quoi le noyau?
It is the brain of the cell, with dna.
What is the purpose of the nucléole?
To make ribosomes
How do ribosomes go outside of the nucleole?
By the pores
Where do the ribosomes go after leaving the nucleole?
to the reticulum
C’est quoi les mitochondries?
They are responsible for la respiration cellule.
What is the chemical reaction in les mitochondries called?
Métabolisme
what are ribosomes
ribosomes are kitchens for protiens
What are the steps for respiration cellulaire?
Nouriture + Oxygene = Co2 + Eau + Energy
Where can you find ribosomes
in the cytoplasmique or in the reticulum
What is L’apperiel de golgi
It takes protiens and sorts them in packages called vesicules
What are vesicules
They transport proteins,
nutrients and water to the inside and outside of the cell.
What are les vacuoles
Les vacuoles sont des contenants des déchets ou de nourriture.
Are vacuoles smaller or bigger in animaux compared to vegetales
Elles sont plus petites chez les
cellules animales que les cellules végétales.
What are lysosomes
Les lysosomes sont les recycleurs des cellules. Ils digèrent les organites usés.
C’est quoi le paroi cellulaire
The paroi cellule is very rigid and durable and protects the cell. It is why plants are so strong
C’est quoi les chloropastes
They are in charge of the photosythese
What are les vacuoles
