Virus

If you have a cold this is the virus that you would find inside yourself. As you might have figured out this is the cell that causes the common cold. This virus sort of fits in to that category because it look like a booger. Viruses are too small to be seen by the naked eye. they cant multiply on their own. They consist of DNA and RNA. they are sourrounded by a protective coat of protien.

Bacteria
A prokaryotic cell
  • Bacteria are also one of the smallest organisms there are!
  • Bacteria also cause Salmonellae .
  • The most common Prokaryotes are bacteria.
  • They live everywhere.
  • They have DNA but no Neucleus
  • They have a strong weblike exterior wall.
  • They do not have any ribosomes

Archaea

Archea are small single celled organisms that have a cell wall and do not have a well, defined nucleus. Archea very similar to bacteria but have a different ribosome structure and tend to be extremophiles. Extemophiles can live in extreme conditions such as high and low temperatures.

Cells Cells are in everything there are cells in air, grass, plastic food ect.. also there are two types of cells, Animal cells(top) and plant cells (bottom) Nucleus-Holds the DNA Rough ER-Ribosomes are made here Smooth ER-Lipids and fats are made by the smooth ER

Ribosomes-- Cell organelle made of RNA and protein

Cell wall - Gives support to a cell

Cell membrane-Protects the cell Cytoskeleton A web of proteins,acts as a muscle and skeleton Mitochondria- Sugar is broken down and made into energy

Chloroplasts-Where photosynthesis takes place

Golgi complex-Make and package materials to be transported out of the cell Vesicle- A small suck that surrounds material to be moved in or out of the cell

Large Central Vacuol- the organelle that stores water and other materials

Lysosome-The organelle thatdigests food particles wastes cell parts and foreign inveiders

Animal Cell

The Animal cell has about the same things as the plant cell but with oter things (look at the pics for other examples.) like lysosomes ect.

Animal-Cell.jpg

Organelles:

Ribosomes

Endoplasmic Reticulum

Nucleus

Mitchondria

ER

Smooth ER-

Cell wall

Cell membrane

Cytoskeleton

Chloroplasts

Golgi complex

Vesicle

Large Central Vacuol

Lysosome

Plant Cell:

The plant cell has the same things as the animal cell but with some other things. like a vacuole ect.

Function of Organelles(Plant and Animal)

  • Ribosomes-Ribosomes are the smallest of all organelles. And there are more ribosomes in a cell than there are any other organelles.
  • Endoplasmic Reticulum- a system of folded membranes in which proteins, lipids, and other materials are made.
  • Nucleus-a large organelle in a eukaryotic cell. It contains the cell’s DNA, or genetic material.
  • Mitchondria- the organelle in which sugar is broken down to produce energy.
  • ER-Ribosomes are made here
  • Smooth ER-Lipids and fats are made by the smooth ER
  • Cell wall - Gives support to a cell
  • Cell membrane-Protects the cell
  • Cytoskeleton -A web of proteins,acts as a muscle and skeleton
  • Chloroplasts-Where photosynthesis takes place
  • Golgi complex-Make and package materials to be transported out of the cell
  • Vesicle- A small suck that surrounds material to be moved in or out of the cell
  • Large Central Vacuol- the organelle that stores water and other materials
  • Lysosome-The organelle thatdigests food particles wastes cell parts and foreign invaders

------------------------------------------------------------------------------------------------------------------------------------------------------ Definitions:

Virus- nonliving structure that attacks cells and multiplies by injecting RNA or DNA telling the cell to make multiple copies of the virus.

Bacteria- small single celled organisms that have a cell wall and do not have a well, defined nucleus.

Archea-small single celled organisms that have a cell wall and do not have a well, defined nucleus. Archea very similar to bacteria but have a different ribosome structure and tend to be extremophiles. Extemophiles can live in extreme conditions such as high and low temperatures.

Eukaryotic cell

Next I will talk about the Eukaryotic cell. Some facts on Eukaryotic cell are:

  • Eukaryotic cells have a membrane bound nucleus.
  • Animal cells and plant cells are eukaryotic
  • Eukaryotic cells have many organelles that preform functions within the cell
  • Some organelles are big enough to be seen with a light microscope
  • Are about 10 times bigger then prokaryote cells.



Things to know about eukaryotic cells:
  • Ribosomes-Ribosomes are the smallest of all organelles. And there are more ribosomes in a cell than there are any other organelles.
  • Endoplasmic Reticulum-s a system of folded membranes in which proteins, lipids, and other materials are made.
  • Nucleus-a large organelle in a eukaryotic cell. It contains the cell’s DNA, or genetic material.
  • Mitchondria- the organelle in which sugar is broken down to produce energy.

Prokaryotic Cell
Finally i will talk about Prokaryote cells. These as you know are 10 times smaller than Eukaryotic cells
some facts on prokaryotic cells are:
  • Bacteria are an example of Prokaryotic Cells
  • Their DNA are unprotected and circular
  • around 8 micrometers long
  • Cell wall is made of a different material



Things to know about Prokaryotic cells:
  • Flagellum-a whiplike tail that helps certain cells to move using the same principles as a propeller.
  • Cell membrane-a protective barrier that encloses a cell.
  • Cell Wall- a rigid structure that gives support to a cell.
  • Ribosomes-Ribosomes are the smallest of all organelles. And there are more ribosomes in a cell than there are any other organelles.

Photosynthesis-The process by which plants get energy from sunlight.


Mitosis

Mitosis-It is in Eukaryotic cells, it is a process of cell division

Now for a catchy tune about bacteria

I cant beleive that there are such things as flying squirrles thats amazing. I hope to see one in the future. I wonder where they live and where i can get one. I wish one of my friends had one, because my parents definatly would not let me have one.
