Botany Snippets, Episode 1: Why Do Cacti Have Spines?! [CC]


Greetings guys gals and non-binary pals!
Welcome to a new segment on the channel called
botany snippets, in which there’s gonna be a short segment on a particular topic
answering one question each day or each weekday and I’m gonna try and get it out
relatively frequently, so there we go. Today, if you have read the title I don’t
know why I’m doing this it’s down here now but if you read the title it’s: Why
do cacti have spines?! So cactus spines are modified leaves or modified web
scales which is kind of a moot point because modified but scales are modified
leaves it’s it’s one of those not all modified leaves are bud scales would all
want to find bud scales are leaves so there you go. And in most species the
spines occur at the axial of the leaves which is the point on the main stem
where the shoots or buds develop which if you ever seen a cactus that’s
blooming or pre bloom when it’s kind of still bud be but it is coming out of a
space that has the spines because it’s an axial spot yeah so additionally the
spines are defense mechanism as you might have guessed to deter predation
because if something is spiky, animals are less likely to try and eat it or
carry it off or is generally mess with it in any fashion so there you go. I’m not used to doing a one-question type thing but I’ve seen a couple of other people do it and it seems to work and it would
actually get me and I haven’t of including more frequently, which I kinda want to do so there we go. So if you come back tomorrow and we’re
going to continue the cactus questions for the rest of the week and then switch
to something else next week Alright. See you later. Have a good one. Oh, ya out-trow things if you haven’t already hit the subscribe
