🔬 Structure of eukaryotic cells

The core components of cells are the outer membrane , the cytoplasm (substance inside which contains all other stuff) and the nucleus (contains DNA). All the other stuff is made up of various components with specific functions – these are called organelles .



The ones you must know about are:


1. Cell-surface membrane
2. Nucleus

3. Mitochondria
4. Chloroplasts (plants and algae)
5. Golgi apparatus and Golgi vesicles
6. Lysosomes
7. Ribosomes
8. Rough endoplasmic reticulum and smooth endoplasmic reticulum
9. Cell wall (plants, algae, fungi)
10. Cell vacuole (plants) In complex multicellular organisms, eukaryotic cells are specialised and therefore organised accordingly into tissues, organs and systems. For example, a small intestine epithelial cell which absorbs nutrients from food is part of the epithelium tissue of the small intestine organ of…
