Eucaryotic cells (exam around the corner)

• Eucaryotic cells and it´s organelles, to be precise.

• Sorry, if you find this meticulous approach annoying, I just think it´s pretty important to be precise in this field.

• Imagine a brain surgeon who decides to round things up a little and slice off a bit more neurons than necessary.

• Personally, I don´t think it´d cause me much damage, since, according to my mom, I only use like five percent of my brain capacity.

• I´ll try to use at least ten percent of that capacity (which I do like once in a blue moon) to write something coherent.

• Not sure whether I´ll be succesful, but I´ll try.

• I have an upcoming exam (on Wendnesday, if we again want to be precise), so it´s as much for my own good as for yours.

• Let´s assume we already know what the cell is (but if not: it´s the basic unit of life, i.e. the smallest *living* thing you can find) It can come in various shapes: - circular (adipose tissue/fat cells) - biconcave or dyscocyte (RBC - red blood cell) - amoeboid (WBC - white blood cell, leukocyte) - oval head, long tail (sperm) - long, narrow, almost rectangular (columnar epithelium) - long, stretched, branched (nerve cells) I never thought English is more exhausting than right now.

• I wanted to write that the whole point of this was just to declare that nevertheless they’ve various shapes, their structure is the same, but sincerely...what kind of person would I be if I’d do that?

• In plant cells, it separates the cell from it´s enviroment and it also serves to support/protect them - it´s a stiff, rigid and permeable structure that surrounds the cell membrane - but only can be found in plant cells.

• Next we have plasma membrane, consisting of two layers of phospholipids, interspersed with proteins and cholesterol throughout the structure.

• It also supports and protects the cell - it controls movement of substances into or out of the cell.

• (it´s semipermeable) In regard to animal cells, it also separates the cell from its environment.

• I know that it´s terrible when someone only brushes the surface of the topic and never gets to the deep stuff - but haven´t we got deep enough with these two already?

• I believe correcting this text must have been as hard as writing it...so I´m indeed indepted to the crazy nerd who undertook the task.

• (or should I say geek?

• Sorry, whatever it is, I meant the nicer word, but reading mainly historical fiction, I´m not really sure which one to use.

• Could you please explain to me the shades of these words?

• I can´t believe my luck, that I stumbled onto this page!) Eh, yeah...what I wanted to say was that let´s just list the other organelles instead going deep...to get the vocabulary more quickly.

• It´s a pity, because I kind of enjoy being this nerdy (using double the usual capacity of my brain isn´t as hard, when your starting point is set low.) But let´s list the organelles: -Cytoplasm -Ribosome -Nucleus -Endoplasmic Reticule -Golgi Body - Mitochordria - Chloroplast -Vacuole -Lysosome If you´d like, I´ve got like ten pages of text I can slowly translate later to get real specific with each of these bodies (can organelle be called a body?), but now I gotta go...the time flies way too quickly, if you ask me.
