Cells And Organism Organisation Flashcards
Identify the key organisation levels of an organism and why each level is important.
Cells - make up everything, smallest functional unit of an organism.
Tissues - make up organs, also perform simple functions in the body.
Organs - perform vital functions in the body, make up organ systems.
Organ systems - perform vital functions in the body. Organism would die without them.
Organism.

What is the function of the Nucleus?
Contain the DNA
Communicates with cytosol via nuclear pores
What is the function of the nucleolus?
Produces ribosomes.
What is the function of the cytoplasm/cytosol?
Contains all the organelles.
Contains proteins that control cell metabolism.
What is the function of the Centrioles (centromere)?
Produces spindle fibres, allowing cells to perform mitosis.
What is the function of the Golgi?
Packages macromolecules for transportation elsewhere in the cell.
What is the function of the Cell membrane?
Controls entry and exit of substances.
What is the function of the mitochondria?
Powerhouse of the cell.
What is the function of the vacuole?
Stores nutrients and waste.
Controls turgidity.
Extra “skeleton” for plant cells.
What is the function of the cell wall?
Maintains the shape of the cell.
Provides protection.
What is the function of the chloroplast?
Gives Cell ability to photosynthesise.
What is the function of the Smooth Endoplasmic Reticulum?
Lipid and steroid hormone synthesis.
Breakdown of lipid-soluble toxins in the liver.
Release of calcium in muscle cells.
What is the function of the Rough Endoplasmic Reticulum?
Has ribosomes on surface.
