level questions: Eukaryotic cell structure
| Question | Answer |
|---|---|
| What is the nucleus | Contains the coded genetic information in the form of DNA molecules. |
| What are the threee components of the cytoskeleton | - microfilaments - microtubules - intermediate fibres |
| What are microfilaments | Contractile fibres formed from the proteins actin. These are responsible for cell movement and also cell contracyion during cytokenisis. |
| What are microtubules | Globular tunulin proteins polymerise to form tubes that are used to form scaffold like structure that determine the shape of the cell. |
| What are intermediate fibres | These fibres give mechanical strength to cels and help to maintain integrity. |
| Role of smooth endoplasmic reticulum | Responsible for lipid and carbohydrate synthesis and storage. |
| Role of rough endoplasmic reticulum | Has robosomes bound to the surface and is responsible for the synthesis and transport of proteins. |
