3.1 The cells

A cell is the smallest unit of a living thing capable of performing the three vital functions: nutricion, interaction and reproduction.

Cells have some characteristics in common wich are allways present:

  • Plasmatic membrane
  • Cytoplasm
  • DNA or genetic material

 TYPES OF CELLS

The cells can be classified into prokaryotic cells or eukaryotic cells

  • Prokaryotic cells. Their DNA placed in the cytoplasm. It is the characteristic cell of Monera kingdom organisms (bacteria).
  • Eukaryotic cells. Their DNA is placed inside a nucleus. It is the characteristic cell of protoctists, fungi, plants and animals.
Eukarytic cells have organelles and can be divided into animal eukaryotic cells and plant eukaryotic cells. Plant eukaryotic cells have exclusive organelles. This characteristic organelles in plant eukaryotic cells are choroplast and cellular wall.


ACTIVITIES

1) Write the three vital functions
2) Which are the exclusive organelles of plant eukaryotics cells?
3) What structures have in common all types of cells?
4) Copy all this information in your notebook
