| Front | Draw out a typical eukaryotic cell with all its organelles (specialised structures within a cell). What defines a eukaryotic cell and briefly describe the function of all its organelles |
|---|---|
| Back | A eukaryotic cell is 20 micrometers or more in size, has a true nucleus and has membrane-bound (they are held together by a membrane) organelles Nucleus: contains the cells genome Mitochondria: site of respiration reactions to supply energy Ribosome: site of translation to produce proteins Cytoplasm: fluid containing important metabolic substances Cell membrane: fluid mosaic model controlling movement in/out of cells Nucleolus: small dense body in nucleus where ribosomes are made and which leave into cytoplasm through pores in nuclear membrane Centrioles: hollow cylinders / microtubules made of long globular proteins which form spindles during mitosis Rough endoplasmic recticulum: flattened sacs with ribosomes attached (proteins travel through this and are folded here) Smooth endoplasmic recticulum: flattened sacs that produce lipids and steroids which leave through vesicles Golgi apparatus: made from sacs made from vesicles made from smooth endoplasmic recticulum which modifies and packages proteins into secretary vesicles for transportation Lysosomes: sacs of digestive enzymes like acrosome to help break down dying cells/cell structures that need replacing |
