Cell Structure 🧫

What is the location and function of the cell membrane?

Location: External boundary of the cell

Function: Confines cell contents; regulates entry and exit of materials

Where are lysosomes found and what do they do?

Location: Throughout cytoplasm

Function: Digest invading cells or break down old organelles

Where are mitochondria located and what is their role?

Location: Scattered throughout the cell

Function: Control release of energy from foods; form ATP

What is the location and function of the Golgi apparatus?

Location: Within cytoplasm

Function: Process lipids and proteins and package them for exocytosis

Where are centrioles located and what do they do?

Location: Two rod-shaped bodies near the nucleus

Function: ‘Spin’ the mitotic spindle

Where is the smooth ER found and what does it synthesize?

Location: Within cytoplasm

Function: Synthesizes lipids

What is the role of nuclear pores and where are they found?

Location: Within the nuclear membrane

Function: Allow mRNA to move into the cytoplasm

Where is the rough ER located and what is its function?

Location: Flattened membranous sacs near the nucleus

Function: Synthesizes proteins

Where are ribosomes found and what do they produce?

Location: Attached to membranes or scattered in the cytoplasm

Function: Synthesize proteins

What is the function of cilia and where are they found?

Location: Hair-like structures on the surface of some animal cells

Function: Move substances across the cell surface in one direction

Where are microtubules found and what do they do?

Location: Throughout cytoplasm; part of cytoskeleton

Function: Contractile protein (actin); move cell or cell parts; core of microvilli

Where is the nucleolus located and what is its function?

Location: Within the nucleus

Function: Involved in synthesis of ribosomes

What is the nucleus, where is it located, and what does it contain?

Location: Large body situated towards the centre of the cell

Function: Contains genetic information
