Organelles within the cell

Nucleus – Contains genes and controls cellular activity

Ribosomes – Sites of protein synthesis

Endoplasmic Reticulum – Contributes to the mechanical support and distribution of cytoplasm, intercellular exchange of materials within the cytoplasm, provides a surface area for chemical reactions

Golgi complex – Packages synthesised proteins for secretion in conjunction with Endoplasmic Reticulum, forms lysosomes, secretes lipids, synthesizes carbohydrates

Mitochondria – Sites where production of ATP takes place

Lysosomes – Digests substances and foreign microbes

Peroxisomes – Contains several enzymes related to hydrogen peroxide metabolism

Microfilaments and Microtubules – Form part of the cytoskeleton

Centrioles – Help organise mitotic spindle during cell division

Flagella and Cilia – Allow for movement of the cell, or of particles trapped within mucus on the cell surface
