2 ANIMAL AND PLANT CELL

3 DESCRIBE THE PICTURE

4  eukaryotic organisms:  plants  animals  fungi  they are both monocellular and multicellular EUCARYOTIC CELL

5  larger and more complex than prokaryotic  evolutionarily much younger than the prokaryotic cell  differentiated nucleus  nuclear chromosomes  a big amount of membrane organelles EUCARYOTIC CELL

6  it determines the form of cells  an important role by the cell division and differentiation  cell wall of fungi – of chitin  cell wall of plants – of cellulose  in the walls of plant cells there are plasmodesmata = communication channels CELL WALL

7 MEMBRANE ORGANELLES  specialized for various functions  nucleus  endoplasmic reticulum  Golgi system  lysosomes, peroxisomes, vacuoles  mitochondria and plastids  every time closed utricles  flat utricles = tanks

8  nucleus  the largest and the most marked formation  double membrane  nuclear membrane contains nuclear pores => substance exchange (metabolism)  the main content of the nucleus are chromosomes  control centre of the cell MEMBRANE ORGANELLES

9 NUCLEOLUS  nucleolus  inside the nucleus  a membrane organelle  one or more round nucleoli  ribosomal RNA + proteins are produced here

10 RIBOSOMES  non-membrane organelle  loosely in the cytoplasm  or can be bound to the membranes of the endoplasmic reticulum  30 nm  the ribosome consists of:  two subunits  rRNA + proteins  function:  synthesis of proteins by the process called translation

11 PLASMA MEMBRANE  7 nm  it does not contain the elements of the respiratory chain  proteins do not participate in the active transfer of ions and nutrients through the membrane > ATP  electric potential - 0,1 V  phagocytosis – absorption of particles from outside
