Hello hivers, I know it's been a while since I've last posted, but I've been having little issues but honestly I'm happy I'm back, it's my first time posting here in this community.
It'll be fun here. I'm not much of an artist but recently I've been trying to learn how to draw, well that majorly because my course in school needs diagrams.
I'm study Science Laboratory Technology, and it involves biology which is a topic that must include diagrams and practicals for full marks, I'm going to share with you a two of my diagrams that I was learning about.
I'm studying ahead of time so I believe that it will be helpful to learn these diagrams so as not have issues understand it in school..
First is the diagram of an Onion cell... It's actually very simple and I'll show the steps.
My materials were very simple just a pencil and eraser, which are basic drawing instruments.
* An onion cell can only be seen clearly through a microscope, so you'll first of all start with a circle to depict the microscope's view of the cell.
* The next step is for you to start drawing a bit rectangular blocks packed together that looks like the cells of the onions, the must not be really rectangular some sides can be a bit irregular but still inside the circle.

* The next step is to draw a black circle in all the blocks because all those are cells, I'll tell you what they are after the steps.

* Then finally you draw lighter circles, and label your diagram along with a title which is very important in drawing.
So that is the microscopic view of an epidermal onion cell, Every cell is made up of a nucleus it is one of the most important parts of a cell, like the headquarters so to say.
So there's no cell without a nucleus, them the lighter circles are called vacuoles, then we have the cell wall, it houses the cell, and then cytoplasm, it is where all the chemical reactions or biological reactions within the cell takes place. To be able to get a view so clear in the microscope, one will need iodine solution before putting it into the glass slide.
Then the second thing I drew is the diagram of Human chew cells or animal cells, the basis of the practical is to identify the difference between a human and an animal cell.
So this is how I drew it..
* They are usually irregular in shape unlike plant cells so I started with a rough circle.
* Then I drew four more rough circles around it to make it five.
* After doing that, I put smaller circles in the middle, by now I'm sure y'all know what this is, I then have them s light shade.

| * I labelled it and put the title of the drawing there. |
As you can see in this diagram, there is no Cell wall, that is one major difference between plants and animal cell there is no Cell wall in animal cell while there is cell wall in plant cell.
Thanks for going through my post, hopefully I'll drop another one soon. See y'all later.
