INTRODUCTION

In this activity, we learned in a creative way about the cells: Prokaryotic and Eukaryotic Cells.

All cells have three basic structures: the plasmatic membrane : is a very thin bag that surrounds the cell and controls which substance go in and out of the cell, the cytoplasm:is a jelly substance ; many of the cell's activities happen there and it contains many cellular organelles, the genetic material (DNA): is a fibre substance that controls the cell's activities

PROKARYOTIC CELL

In prokaryotic cells the DNA floats in the cytoplasm.This cell type is characterize of bacteria (monera kingdom) only.

Ingredients : Cheese sticks

Bread

blue noodles

1 normal noodle

pieces of olives

-We used bread as base, the cheese sticks as fimbriae, the corner of the bread as the cell wall ,the blue noodles as the genetic material , the normal noodle as the flagellum and we used the pieces of olives as the ribosomes.

PROCESS:

-We placed the Cheese sticks around the bread, we placed the blue noodles in the bread and

we added the names and finally we got these :

EUKARYOTIC CELLS

This type of cell can be found in protoctist,fungiplants and animals.

PLANT CELL

They contain centrioles, special organelles which take part

in cell division and in cilia and flagella formation.

Ingredients: Water melon

peach seed

tangerine

Gummis

candy rainbow

one melon

-We used water melon as base , we used the corner of the water melon as the cellular wall a melon as the nucleus, we used the red part of the water melon as the plasmatic membrane, we used the tangerine as the vacuole and different kinds of gummis as the lysosomes and other membranous vesicles ,mitochondria and chloroplast.

PROCESS:

We cut the water melon , we placed the peach seed in the middle

of the water melon and then we added in the correct side, all the ingrediens the tangerine, the gummis, and the candy rainbow.

ANIMAL CELL

Animal cell ,contain centrioles, special organelles which take part in cell division and in cilia and flagella formation.

Ingredients:Pizza

normal noodles

jam

chilli

olives seeds and shell .

-We used pizza as base ,the jam as the ribosomes,

the chilli as the mitochondria, the shell of the

olive as the nucleus, the cheese of the pizza as the lysosomes
and other membranous vesicles,and we used the normal noodles as the centrioles.

PROCESS:

-First we added the jam and we put the olives seeds in the middle of the pizza,

then we placed the chilli, we added the normal noodles as finally we got these:
