Types of cells

Introduction

Cell is the  basic unit of life and Robert Hooke was the first to use the word cell for structures in living organisms. 

In this presentation you will learn types of cells,their functions and structures. If you are ready,let's begin!!

 

                              

Task

In this experiment, you will learn eukaryotic and prokaryotic cells.

You should learn how to draw a structure and label them.

You should learn organalles functions too.   So, its your task to learn them and try to draw and label the structures which are given. Try to draw them like in the book. Watch the videos, they will help you to understand the topic better.

Good luck

Process

Prokaryotes:

You will see a picture which shows you prokaryotic cell and explanation of organelles.

Escherichia coli:                                                        

                              

And here is a eukaryotic liver cell and its organalles:

                            

Evaluation

Here is a video which shows us the differences between prokaryotic and eukaryotic cells.

Lets watch and have fun :)

Conclusion

To sum up, there is some differences between eukaryotic and prokaryotic cells.

Eukaryotic cells contain membrane-bound organelles, such as the nucleus, while prokaryotic cells do not. Differences in cellular structure of prokaryotes and eukaryotes include the presence of mitochondria and chloroplasts, the cell wall, and the structure of chromosomal DNA.

So, have a look at the table to see differences properly.

Eukaryotic Cell

Eukaryotic cell

Prokaryotic Cell

Prokaryotic Cell
Nucleus Present Absent
Number of chromosomes More than one One--but not true chromosome: Plasmids
Cell Type Usually multicellular Usually unicellular (some cyanobacteria may be multicellular)
True Membrane bound Nucleus Present Absent
Example Animals and Plants Bacteria and Archaea
Genetic Recombination Meiosis and fusion of gametes Partial, undirectional transfers DNA.
Lysosomes and peroxisomes Present Absent
Microtubules Present Absent or rare
Endoplasmic reticulum Present Absent
Mitochondria Present Absent
Cytoskeleton Present May be absent
DNA wrapping on proteins. Eukaryotes wrap their DNA around proteins called histones. Multiple proteins act together to fold and condense prokaryotic DNA. Folded DNA is then organized into a variety of conformations that are supercoiled and wound around tetramers of the HU protein.
Ribosomes larger smaller
Golgi apparatus Present Absent
Chloroplasts Present (in plants) Absent; chlorophyll scattered in the cytoplasm
Flagella Microscopic in size; membrane bound; usually arranged as nine doublets surrounding two singlets Submicroscopic in size, composed of only one fiber
Permeability of Nuclear Membrane Selective not present
Plasma membrane with steroid Yes Usually no
Cell wall Only in plant cells and fungi (chemically simpler) Usually chemically complexed
Cell size 10-100um 1-10um
