Cell Structures, Organelles And Functions Flashcards
What is the cytoskeleton and what is it’s function?
Microfilament fibres that provide support and structure of the cell
What is the main function of the Nucleus?
Controls WHAT cellular events happens and WHEN they happen
Cytoplasm is made up of _______ and ______
Cytosol, Organelles
What is the function of the rough endoplasmic reticulum (RER)
To synthesise proteins and transport them via transport vesicles to the Golgi body prior to secretion.
Function of microvilli?
To speed up secretion and absorption due to the large surface area
What synthesises lipids to be secreted from the cell?
Smooth endoplasmic reticulum (SER)
What does the Mitochondria do?
Releases energy in the Adenosine Triphosphate (ATP) for cell use
What digests unwanted cellular material?
Lysosomes
What is the main function of the centrioles?
To help seperate duplicated chromosomes during mitosis
What secretes substances from the cell?
Secretory vesicles
The Cell structure consists of
Cell Membrane, Cytoplasm, Nucleus.
What synthesises RNA (part of ribosomes)?
Nucleolus
Main function of the Golgi body?
Receives proteins and lipids from the ER and packages them up into membrane bound secretory vesicles.
Cytoplasm consists of _______ and _______.
Cytosol and organelles
Hair-like extensions on the surface of some human cells are called _______. They beat and move to create a current around the cell or to remove mucus
Cilia
