Question

Can someone help me understand a little bit more about cells?

Answer 1

Hi!

Answer 2

hi

Answer 3

So how can i help you today ?

Answer 4

I just i'm really bad at like science and cells so i jest need like help to understand it better because im getting homework that has to do with cells but i just can't really do it since cells is like the most complicated thing (to me at least) and the endosymbiosis theory

Answer 5

So have you read about it in your book ?

Answer 6

yes but for some reason like it doesn't go through my head its like im just reading cause i have to read im not understanding... and i really want to understand

Answer 7

Ok, so do on ething, ask me the thing which is not going through your head....

Answer 8

OKay so basically what is a cell and what is it's function? and how is mitochondria got into the Eukaryota cell because i know it was like a cell it's cell of at least that's what they thought and what is each organelle and what is like their function what does it do to help out the cell? i think that's basically it for now but i might have more questions later once we get specific

Answer 9

Ok, first of all just know one thing that cell as a topic is very easy........

Answer 10

ok ?
So remove everything from your mind....

Answer 11

Now, do you know about atom ?

Answer 12

It is the smallest functional unit of an element...similarly in an analogous way, cell is the smallest functional unit of a living being. Anything less than a cell can't be living.

Answer 13

ok ?

Answer 14

?

Answer 15

okay and sorry my connection got messed up

Answer 16

so what is smaller a cell or atom?

Answer 17

An atom.....

Answer 18

oh okay sorry

Answer 19

Cells are made up of many atoms.....actually the largest cell is ostrich egg, you can see it with your naked eyes.

Answer 20

Ok, now let's proceed. Cells are of two types....The one which evolved earlier and are primitive are called Prokaryotic cells and those which evolved later and are more complex are called as Eukaryotic cells.

Answer 21

okay so i know the eukaryotic cells is for animals and plants, is prokaryotic for bacteria?

Answer 22

Yes, now every cell which do not have a membrane bound nucleus is grouped under prokaryotic cells. Like bacteria..

Answer 23

And all those which have a membrane bound nucleus, like animal cells, plant cells are eukaryotic cells.

Answer 24

okay and how about the ones with and without the cell walls?

Answer 25

Even, Fungi is eukaryotic, Plasmodium the parasite which causes malaria is also eukaryote.

Answer 26

Animals don't have cell walls....and they are eukaryotes..

Answer 27

okay

Answer 28

okay i don't know what protozo is but this picture you sent really helped me understand it better

Answer 29

Yes, actually i don't know how much to tell you...like in which class are you ?

Answer 30

Biology 1

Answer 31

No i mean....what level ?

Answer 32

ok..leave..i'll try to keep it basic..

Answer 33

So, shall we move to organelles...?

Answer 34

okay and yes i know some like nucleus, chromosomes, mitochondria

Answer 35

Ok, but before we move on tell me what is the difference between eukaryote and prokaryote..?

Answer 36

okay Eukoryatic cells is for any=imals and plants and fungi and protozo Prokaryotic is cells is for bacteria the cells is made up of atoms not one but many that form and make one huge cell; cells is the smallest thing in our body that functions by its cells are so small that you need them to be magnified to see them but the largest one that you can see with your own eyes without magnifying glass or anything is the ostrich egg.....am i missing anything else?

Answer 37

and prokaryotic cells don't have a membrane bound nucleus

Answer 38

Yes, that's the main difference !

Answer 39

Always mention the last point..

Answer 40

okay

Answer 41

k, now gv me 5 mins or 10 mins for my supper...i'll be back...untill then you can read organelles and endosymbiotic theory from ur book.

Answer 42

okay enjoy your supper :) and thank you for helping me understand a little more :)

Answer 43

m back !

Answer 44

Let's see organelles..

Answer 45

Like every city needs officers to run, The city of cell also have some officers whom we call organelle. Let's see some of them and their functions.

Answer 46

oky

Answer 47

Nucleus, this guy is the Mayor of cell, it controls every activity happening in the cell. It has DNA which has all the genetic information stored in it.

Answer 48

okay so it is basically like if we were to say that the cell is a human will the nucleus be the brain?

Answer 49

Now, you will learn one more difference between prokaryotes and eukaryotes. Eukaryotes have membrane boun organelles like, Nucleus, Mitochondria, Chloroplast, Golgi complex, Endoplasmic Reticulum etc. Prokaryotes don't have membrane bound organelles.

Answer 50

Yes, nucleus will be the brain..good.

Answer 51

okay doesn't the eukaryotic cell only have the DNA by the nucleoid ?

Answer 52

Mitochondria is the power house of the cell. It's job is to produce energy by cellular respiration. It's job is to synthesize ATP (the energy molecule)

Answer 53

okay doesn't it do that by using oxygen and breaking down food?

Answer 54

Prokaryotic cell has DNA inside nucleoid and Eukaryotic cell has DNA inside nucleus. Nucleus is membrane bound true organelle but nucleiod do not have a membrane..

Answer 55

Yes, mitochondria produce energy by using oxygen and breaking down food. This is called cellular respiration.

Answer 56

okay i think im understanding this even better now

Answer 57

Good, what's next ?

Answer 58

maybe the lysosome?

Answer 59

ok, So these are also membrane bound organelle. This guy has hydrolytic enzymes (breaking down enzymes). They digest everything inside the cell which is unwanted.

Answer 60

Hey, i found notes on this topic....it may help you..would you like to have it ?

Answer 61

Check this out
