Unit 1: Section 3 - Cell Structure and Membranes Flashcards
Name two parts of eukaryotic cell that prokaryotic cells don’t have?
Nucleus and mitochondria
Are prokaryotic or eukaryotic cells more complex?
Eukaryotic cells
Parts of a cell are called ?
Organelles
What surrounds a cell?
Plasma membrane
What is the function of the plasma membrane?
Regulates the movement of substances into and out of the cell
What two things would you find in the nucleus and what surrounds the nucleus?
Contains the nucleolus and chromatin, surrounded by the nuclear envelope
What is the nuclear envelope?
Double membrane which surrounds the nucleus
What is the function of lysosomes?
Contains digestive enzymes to digest invading cells and dead organelles
Where are ribosomes made in the cell?
In the nucleolus
Where are proteins made in the cell?
In the ribosomes
What are the two types of ER called?
Smooth and rough
What’s the function of the nucleus?
To control cell activity
What’s the function of the smooth ER?
Makes and transports lipids
What’s the function of the rough ER?
Processes and transports the proteins which gave been made by the ribosomes
What two organelles would a plant cell have but not an animal?
Chloroplasts and a cell wall
What us the function of the Golgi apparatus?
Modifies new proteins
What does the Golgi apparatus contain to transport protein in?
Vesicles
What in the cells produces energy through aerobic respiration?
Mitochondria
Do mitochondria have a single membrane?
No double
The inner membrane of a mitochondria fold into?
Cristae
What’s the inside of the mitochondria called?
Matrix
What will a cell contain more of if it uses a lot of energy ?
Mitochondria
What cells line the small intestine?
Epithelial cells
What are micro villi?
Finger like projections on the villi
