Bacterial spores (1st year uni)

Hey ppz! I'm just a bit confused about spores (aka endospores). Has anyone got a link to a good pic that shows spores and the bacteria in the colony please?
also, I don't understand how spores actually do anything and there formation from vegetative cells.

Help please?

Thank you sooo much. btw, i'm i correct in thinking that 'vegetative cell' refers to any somatic cell, so is in this case any normal bacterial cell?

Well vegetative growth is just when the bacteria is under no pressure so just replicates away steadily, so it would be growing in a medium where it has every nutrient require supplied to it. Whereas it will begin to undergo sporulation when it is put under some kind of stress, such as if you wapped it in mimimal medium

ok thanks. i was confused before and thought that maybe a spore is a kind of specialised cell. actually is it classed as a cell? it does after all have a nucleiod, right?
Is it only me, or is this thing possible to find in two minutes and master in another five? Thanks for the hyperlink though, raceforthefishman. It surely is a nice presentation. :smile:

i's just you. lol

but seriously, you can find information using google, but none of them explain it as well as the link given by raceforthefishman. could you answer my question? is a spore categorised as a cell? i think it is but want some confirmation. :smile:

:erm: haha I was supposed to know this for my microbiology module. Its like a sort of pre cell state, so this is why its important when cooking some food to be aware of spores. The actual bacteria cell could be killed off and only spores left -- which could develop into bacterial cells later. I'm not too sure how you'd classify them really!

Biology is not my major academic field, but as far as I know, spores are one-celled only typically, so there are other possible types with more cells within a single spore. It is a form more than an organism.

EDIT: Actually, bacterial spores could only consist of a single cell as I have learned a while ago, so although I would not bet my life on it, a bacterial spore is a form adopted by a bacterial cell. That basically means that it is a cell because analogically, a cell in a dead form is still a cell, is it not?

As in bacterial endospores? I don't think you;re right there....I could be wrong though. You can get different types of spores

I have edited my original post a bit. It should be correct now. I gave it only three minutes instead of five, sorry. (Now I am joking.)
