Cell membrane Double layered of molecule i.e lipid bilayer Made up of phospholipids and associated protein. 6/3/2024 cellular organelles 3
Cell membrane Bilayer of lipids and proteins. Only specific material may enter and exit through pores and protein channel. Molecules like H 2 o & O 2 pass through membrane easily. Large molecule like glucose need to pass through protein channel. 6/3/2024 cellular organelles 4
Cytoplasm Jelly like material inside cell. Most cell organelles float within cytoplasm. Chemical reactions take place here. Dissolve solutes and move materials around. Add support to cell. 6/3/2024 cellular organelles 5
Nucleus Control cell activity Contain DNA (chromatin- long strand of DNA, hold info to make protein). Nucleolus makes ribosomes. 6/3/2024 cellular organelles 6
Endoplasmic reticulum Rough endoplasmic reticulum Covered in ribosomes Nucleolus makes ribosomes then exit nucleus and travel along tunnel. Tunnel system that transport protein making ribosomes 6/3/2024 cellular organelles 7
Smooth endoplasmic reticulum Not covered in ribosomes. To make lipids and fats. Help breakdown toxins. 6/3/2024 cellular organelles 8
Ribosomes Created by nucleolus. Transported by RER To make protein Gather indiv . Amino acids(building block of protein) Building long chain of amino acid k/a protein i.e translation . 6/3/2024 cellular organelles 9
Golgi body Receives protein that ribosomes made Modifies, sorts and packages them. Releases protein inside a protective vesicle. 6/3/2024 cellular organelles 10
Mitochondria Create ATP in process called cellular respiration. Endosymbiosis theory- own DNA and ribosomes, reproduce and replicate. 6/3/2024 cellular organelles 11
Lysosomes Contain digestive enzymes. Break down food and protein into small parts(amino acid) Kill pathogen Autolysis 6/3/2024 cellular organelles 12
Cilia and flagella For movement Cilia- short hair like extension Flagella- long whip like extension 6/3/2024 cellular organelles 13
