Biology - CELL STRUCTURE AND FUNCTION 1 Flashcards
What is the structure of the nucleus?
sphere is the centre of the cell
What is the function of the nucleus?
it contains DNA
What is the structure of the nucleolus?
In the centre of the nucleus
What is the function of the nucleolus?
Ribosomes are made in the nucleolus
What is the structure of the RER?
Folded membrane near the nucleus. Has ribosomes on it
What is the function of the RER?
Protein synthesis
What is the structure of ribosomes?
Made up of two subunits of RNA
What are the function of ribosomes?
Protein synthesis
What is the structure of the SER?
Folded membrane near nucleus. No ribosomes
What is the function of the SER?
Lipid and carbohydrate synthesis
What is the structure of the golgi?
Folded membrane
What is the function of the golgi?
Protein modification
What are lysosomes?
Large vesicles that contain enzymes
What is the function of lysosomes?
Breaks down bigger molecules into smaller ones using enzymes
What is the structure of mitochondria?
Pill shaped. Double membrane
What is the function of mitochondria?
ATP production and aerobic respiration
What is the structure of centrioles?
Two organelles, with microtubes running through them
What is the function of centrioles?
Forms the cytoskeleton
What is the structure of the plasma membrane?
Fluid mosaic model
What is the function of the plasma membrane?
controls what comes in and out of the cell
What is the structure of vesicles?
Spheres of membrane near golgi
What is the function of vesicles?
Transports substances
What is the structure of the cytoplasm?
Jelly like substance which fills the cell
What is the function of the cytoplasm?
where chemical reactions take place
