CELL
Cell are made up of a lot of parts . Each and every part is important because of them the cells are able to function properly.There are 2 type/kind of cell that we are talking right now. Animal and plant cell. Let's start with the animal cell.
ANIMAL CELL
The 4 main partfor a typical animal cell is:
- Nucleus:
The nucleus control everything that is happening inside a cell. It is located in the cytoplasm.
- Cell membrane:
Cell membrane is a thin soft outermost layer of the cell. It contains cytoplasm in it.
- Vacuoles:
Vacuoles is the part of the cell which play the digestion part inside the cell.
Cytoplasm is a jelly like substance that let substances such as oxygen and food to be transported around the cell.
PLANT CELL
The plant cell has 6 main part for a typical plant part is almost the same as the animal cell. The only thing different is the chloroplast and the cell wall. For the vacuole in the plant part function differently.
- Chloroplast
Chloroplast is a tiny green structures that contain chlorophyll. Chlorophyll is a green pigment that traps the sunlight in order for the plant to do photosynthesis. Not all plants have chloroplast.
- Cell wall
Cell wall is the outermost layer of the plant cell and it give the plant cell it's shape.
- Vacuole
Unlike the animal cell vacuole in the plant cell contain the cell sap which keep the cell firm.
CELL DIVISION
Like all organism cell grow by multiplying. Cell also multiply to replace the old cells. This process took place in organism all the time.

MULTICELLULAR ORGANISMS
As we grow, our body also increases in size. This is because cell in our body increases. Our body cells multiply by a process called cell division. Not only that they also go through the process called mitosis.
UNICELLULAR ORGANISMS
Unicellular organisms grow by multiplying themselves.
- Yeast
There is an exception for yeast. they grow by using a special method called budding. In the process called budding, a small bud will grow in the yeast cell. They will eventually break away from the parent cell once they have reached the same size.
In my school me and my friends also try to experiment about cell division.
This is the materials that we used during our expieriment:
- 2 balloons
- 2 flask
- measuring tape
- stop watch
- hot/boiled water
- sugar
- yeast (fermipan)
After we prepared all of that, the next thing we do is put the boiled/hot water insinde both of the flask. After that we label flask A and flask B. In flask A we only put the yeast and then mix it with the water. While in flask B we put both the yeast and the sugar and then mix them together. After we mix them we cover the top of both flask with the balloon. If we already cover both of the flas with the balloon we start the stop watch and wait for 45 minutes. And there we have the result.

From this experiment, i know now more about cell division. One of them is that cell need energy to multiply which in this experiment they got it from the sugar. Cell also need certain condition like heat, water and oxygen to grow/multiply.
The post is detailed, enough for me to be bored :/
BalasHapusThe pictures are OK, but its not quite reader-friendly; the background is just brown color with some textures on it. Other than that, executed well you have done.
8 cells out of 10.
