Biology Lesson Number 1 The Cell
Hey Guys, as I couldn't think of any more content for the ketogenic lies series I am just starting something new. It will be a series where I talk about biology in general and explain some principles to you. I try to be as accurate as possible but please be generous with me making mistakes as I am not native English.
Welcome welcome this is the first part of the series and today we gonna talk about the cell. The differences between a bestial and a herbal cell. The cell organelles and their function. So let's not waste any time and get that sh$t rolling.
We start with a graphic:
Every cell has the same basic construction plan. It consists of the Nucleus, the ER, Mitochondrial, Ribosomes, Dictyosomes, Vesicles, the Cell membrane and The Cytoplasma. These parts are obligatory it doesn't matter whether it is a plant or an animal cell.
We can further organize these parts into cell organelles with a simple membrane and cell organelles with a double membrane.
Cell organelles with a double membrane:
Nucleus
The nucleus is the core of the cell it holds the DNA. In addition to that, there are most of the time 2 nucleoli which participate in the creation of ribosomes.
Plastides
Plastides can only be found in plant cells and there are different types of them. The most important are the chloroplasts and the leucoplasts. The chloroplasts contain thylakoids which are stacked into so-called grana. The chloroplasts are the ones which make photosynthesis possible.
The leucoplasts act as a storage for proteins glucose and lipids.
Mitochondria
The mitochondria is the powerhouse of the cell nothing more to say haha. It creates ATP the energy sources for the cell in a process called the citrate-cycle which is basically an oxidation reaction. Internally it is pleated to have a higher surface for reactions.
Cell organelles with a single membrane
**Endoplasmatic reticulum: **
The ER looks like some kind of labyrinth or net which is distributed in the cell. It establishes connections to all cell organelles. There are 2 types of the ER. The rough part which has ribosomes on it and synthesizes proteins and the smooth part which is responsible for the metabolism.
Golgi apparatus:
This apparatus consists of dictyosomes which are stacked for the purpose of creatin more surface for chemical reactions. It's main task is to transport metabolites to other cell organelles.
Lysosomes:
Lysosomes are only found in animal cells. Their main task is to break down substances. They are also called digestion organelles.
That's it for the first part. I hope we see again in the secon. Have a nice day!
