abril salinas cells part 2

Eukaryotic cell , plant

as the same of animal cell is multicellular , it can reproduce into
two ways , asexual and sexual

materials :

baked bread
chantiyi cream
milk
candy

firts we started by mixing the cream with the food coloring , color
green then we cleaned up the table and afte that we started to organised
all the candy as the book said next we started writing the parts
and finally we presented and wrote a blog

Prokaryotic cell

A prokariotic cell is a single cell can be divide into two parts
archaeaand bacteria

acteria and archaea reproduce through asexual reproduction
ussually by binary fission .


materials :

Baked bread
candy
Vanilla cream

first we used a knife to put all the vanilla cream in the bread
then we started puting worms candy next we take a lot of photos
and finally we put the tail

Eukaryotic cell , animal

the eukaryotic cell is an multicellular it can divide into two parts ,
animal cell and plant cell , eukaryotic cell can reproduce trough
asexual reproduction through mitosis and sexual reproduction
through meiosis .

materials :

baked bread
chantiyi cream
coloring (food )
candy

first we started moving around the cream until it was ok then we put the food
coloring and start mixing the cream , after that we put it in all the bread
 next we started decoring it with the candy as it said in the book and
finally we wrote the parts .

Cell parts :

Genetic material

 Genetic material known as Deoxyribonucelic acid (DNA) . DNA is the hereditary material found in the nucleus of eukaryotic cells (Animal and Plant) and the cytoplasm of prokaryotic cells (bacteria) that determines the composition of the organism. DNA is found in the nucleus of every cell and it is exactly the same in each cell. There is another type of genetic material found in cells and viruses known as ribonucleic acid (RNA).

Cell wall

A cell wall is a structural layer that surrounds some types of cells,situated outside the cell membrane,It can be tough, flexible and sometimes rigid and functions to provides cells with structural support and protection and to act as a filtering mechanism. Cell walls are present in plants,fungi and prokaryotic cells.where a major function is to act as pressure vessels, preventing over expansion when water enters the cells.Cell walls are absent from mycoplasmas.

Ribosome

The ribosome  is a complex molecular machine found within all living cells.Ribosomes link amino acids together in the order specified by messenger RNA(mRNA) molecules.Ribosomes consist of two major components: the small ribosomal subunit, which reads the RNA, and the large subunit, which joins amino acids to form a polypeptide chain.

Flagellum

A flagellum  is a lash-like appendage that protrudes from the cell body of certain prokaryotic and eukaryotic cells. The word flagellum in Latin means whip. The primary role of the flagellum is locomotion but it also often has function as a sensory organelle, being sensitive to chemicals and temperatures outside the cell. Flagella are organelles defined by function rather than structure. There are large differences between different types of flagella; the prokaryotic and eukaryotic flagella differ greatly in protein composition, structure, and mechanism of propulsion. However, both can be used for swimming

Fimbriae

In bacteorology, a fimbria ((also referred to as “attachement pili” by some scientists)) is an appendage composed of curling proteins that can be found onmany Gram-negative andsome Gram-positive bacteria that is thinner and shorterthan a flagellum. This appendage ranges from 3-10 nanometers in diameter and can be up to several micrometers long. Fimbriae are used by bacteria to adhere to one another and to adhere to animal cells and some inanimate objects. A bacterium can have as many as 1,000 fimbriae. Fimbriae are only visible with the use ofan electron microscope. They may be straight or flexible.

Process

First we cut in half a water melon,then took out what was inside it,after we put in some jelly,then we let it in the fridge for about 5 or 6 hours. When we took out the water melon with the jelly we put on the top of the jelly some whipped cream(( but just on the middle though)),Then we added a little of gummies to simulate the Ribosomes and we stick some "worm gummies" to simulate the flagellum and the fimbriae.

PLANTS CELLS





Plant cells have several structures not found in other eukaryotes. In particular, organelles called cloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls allow plants to have rigid structures as varied as wood trunks and supple leaves; and vacuoles allow plant cells to change size.

Are too small to be seen with the naked eye: they measure from 0,001 mm to 0,1 mm in size. This is why we call them microscope

All living organisms on Earth are divided into cells. The main concept of cell theory is that cells are basic structural unit of all organisms.

The basic structure of a cell:

All cells have three basic structures:

Plasmatic membrane:

Is like a very thin ball that surrounds the cells and is responsible for controlling what gets into and out of the cell.

Cytoplasm:

In prokaryotic cell is a jelly-like, yet fluid, substance in which all of other cellular components are suspended.

Genetic material:

All prokaryotic cells contain large quantities of genetic materials in the form of DNA and RNA. DNA contains the most of the genes needed for cells growth, survival, and reproduction.

Types of cells:

ü  Prokaryotic cells

ü  Eukaryotic cells:

ü  Plant cells

ü  Animal cells

Prokaryotic cells:

The great majority of cells on Earth are actually prokaryotic, so we are the minority. Prokaryotic is monera kingdom. Are those that do not have a membrane-bound nucleus.

Parts of a prokaryotic:

Flagellum: Helps to move.

Cell wall: surrounds the membrane.

Ribosomes: builds proteins by translating messages from DNA.

Fimbriae: allow bacteria to adhere to target host cell, so play a major role in bacterial virulence.

Eukaryotic cells

The DNA of eukaryotic cells is found inside an organelle called the nucleus. These cells contain a great variety of different organelles in their cytoplasm. Each of each organelles performs a specific function critical to cells survival.

Are two types of eukaryotic cells:

ü  Plant cells

ü  Animal cells

Plant cells:

Plant cells are eukaryotic cells that differ in several key aspects from the cells of other eukaryotic organisms. It has distinctive features include.

Animal cells:

DNA in animal cells is housed within the nucleus. In  addition to having a nucleus, animal cells also contain other membrane-bound organelles, or tiny cellular structures.

Animal cells and plant cells organelles:

              I.        Cell wall (only plant cell)

            II.        Plasmatic membrane

           III.        Nucleus

           IV.        Ribosomes

           VI.        Mitochondria

First step: Cut the melon whit the cell shape

Second step: Fill the spaces to make parts of your cell

Third step: shaping the fondant shaped material formed in the cell.

Fourt step: You have to select M&M  colors.

Fifth step: Then you have to put the M&M oranges in the center of the melon.

Sixth step: Then you have to put jelly beans around the melon, and the fondant under the M&M.

Finally: The cell of animal is like this.
