2.1.1: Structure of eukaryotic cells

#2.1.1.1

The structure of eukaryotic cells, restricted to the structure and function of:

  • cell-surface membrane
  • nucleus (containing chromosomes, consisting of protein-bound, linear DNA, and one or more nucleoli)
  • mitochondria
  • chloroplasts (in plants and algae)
  • Golgi apparatus and Golgi vesicles
  • lysosomes (a type of Golgi vesicle that releases lysozymes)
  • ribosomes
  • rough endoplasmic reticulum and smooth endoplasmic reticulum
  • cell wall (in plants, algae and fungi)
  • cell vacuole (in plants).
#2.1.1.2

In complex multicellular organisms, eukaryotic cells become specialised for specific functions. Specialised cells are organised into tissues, tissues into organs and organs into systems.

#2.1.1.3

Students should be able to apply their knowledge of these features in explaining adaptations of eukaryotic cells.
