CAM photosynthesis is a clever adaptation some plants have where they turn light into sugar during the day, and only breathe in CO2 at night. This lets the plant close up its leaves so they don't lose water during the heat of the day.

CAM plants use sunlight to turn malic acid into sugar, and every night they breathe in plenty of carbon dioxide, storing it as a fresh supply of malic acid. If you have keen senses, you may be able to taste the difference between a CAM plant harvested during the day and one harvested at night because of this variation in sugar and acid content.

Having evolved several times independantly, you see CAM in lots of different kinds of plants: air plants and bromeliads, which have poorly developed root systems; cacti and other succulents, which grow in hot dry environments; you even see it in some aquatic plants. For these, CAM serves not to conserve water, but carbon dioxide - which is of course hard to come by when you don't have any air.

The "crassulacean" part of the name "crassulacean acid metabolism" is there because this phenomenon was first discovered in crassulas. Jade plants are an example of this genus.

    bullshit from cishet guysWhy do some cishet guys feel so entitled to justifications of my sexuality? I present somewhat fruity, so like half of the ones I meet eventually ask me if I'm gay in an inflammatory tone. They are of course never satisfied when I say that I just like people and will always push and push either inmediately or in the next few days. Are you unable to read body language and figure out that I'm not okay with talking about that to you? I know the entire world is made for you so you can go around making people uncomfortable with no consequences but at some point your introspection has got to kick in.

    I think my dad hasn't really processed my being trans because I'm a lesbian, like he'd be mad if I dated men but because I'm interested in women I'm normal in his head.

    Excited to see how he responds if and when I date another trans woman.

    I've decided:

    1. Am just gonna start girlmodding to uni. My jacket of protection is so run down I can't defend it anymore. Shit is literally RIPPING APART AT THE SEAMS. Not to mention the sweltering heat which I just can't stand
    2. If anyone has a problem with me at uni fuck them.
    3. If anyone asks questions, "I was always a girl you just didn't notice, and I thought it was funny to let you think otherwise"

    This is a big step for me cause I'm going from "never girlmodes" to basically coming out permanently. Please hold me to this descision and don't let me change my mind.

    suicide mention (technically I guess)

    Although the summer season is the reason I am doing this, atp, fuck it. I can't take being in the closet anymore. Shit be so bad I CAN'T FOCUS ON MY LECTURES CAUSE I'M CONSTANTLY THINKING ABOUT OFFING MYSELF. Fucking christ.

    Slow trans news day huh.

    CW parental traumaMy dad took my gentle pushback badly and went defensive civility lib.

    I finally told my dad he was the primary source of all my childhood trauma and every time he reaches out I'm re-traumatised, I don't want him to contact me, unless I contact him and I'm done pretending to get along, he can do some work or never talk to me again.

    I feel phenomenal.

    Been feeling better the last couple of days, lunch with my lesbian friend was super nice, never had plantains before and holy shit they were good. Kinda expensive but good. Then we went and picked up a mattress lol.

    I've still got a few more things I want to pack up, we aren't doing it all at once or anything but I'd like to get as much moved as possible.

    Also need to shave everything sooooo bad it looks terrible, worst it's been since I started :/ disappointing tbh, just a really rough few weeks..

    I'm getting really close to just completely cutting my father out of my life (CW transphobia, racism, parental trauma, mention of SA)He asked me how I was going and I said sincerely that I was actually feeling really bad. That hearing that the premier of the state I live in say I should go to a men's prison if I commit a crime, had caused me to have nightmares about being SA-d to death in prison (true nightmare I had).

    And no sympathy, no "that's awful", he just said "oh well he has to say that to win over Muslim voters in the western suburbs of Sydney". I'm done with this man.

    spoilerI told him on the day he was being racist, now I have told him I need more than benign indifference and told him to read Trans Liberation and Trans/Rad/Fem, he's a fucking liberal intellectual with floor to ceiling bookshelves overloaded with non fiction books, but has he read a single book about trans rights since my coming out? Seems very unlikely. Argh. There is a chance he might give me some money I need for planning life stuff and surgeries so I've got the kiddy gloves on but I'm no longer taking this nonsense.

    Feels like I have less words to interact with the world lately. I'll need quite a bit soon when I job hunt and prep to move, so hopefully that changes when I need the energy.

    It's mostly due to people trying to get back into my life again, which always throws me off. I don't consider them to be f*mily, but they can't accept that. Funny how people spend years burning a bridge over and over until you finally escape, then they wonder why you won't talk to them.

    I'll be getting a new number soon, so looking forward to that.

    Logged into my old notes app to see if I could find the name of a DND character I created for a friend's campaign in high school

    Instead I found the details of some of the conversations I'd had with my mom about my gender and WOW they were much worse than I remember... choice selections:

    • I mentioned wanting to start hormones, which she was immediately unreceptive to. She proceeded to grill me on what I hoped to gain from it.

    • Ultimately she said she didn't approve of me going on HRT without much intensive therapy beforehand, while recognizing that I can do what I want as an adult. Seemed unfazed by my plans to talk to medical professionals and listen to their advice.

    Later...

    • She said she wouldn't be able to handle watching me undergo HRT while living with me.

    • She repeatedly stated she knew deep down there must be some other problem, that I am her son and that HRT wouldn't fix anything.

    Thinking about something my mom said earlier and crying. We were doing maintenance on the fish tank and the conversation went something like this

    We were talking about fruit and my mom mentioned me being really picky about it. I joked about having high standards for it (its because of the tism I'd guess but whatever). My dad says something about me not having high standards for the fish tank. Because it looks like shit, has looked like shit, I've been fucking depressed and have barely been taking care of anything. My dad does not see this. Anyway I joke that its half his fish tank too because idk what else to say.

    Anyway then my mom says they got it mostly so my life would have some kind of meaning or purpose (I was extremely, extremely depressed at that point years ago). Im crying so hard rn. She's so right. My life has had no meaning or purpose and I've known it. The fish tank has been fantastic for me. I love fish so much. I've struggled a lot to take care of it, I mean obviously look at me. But I've been so excited about it over these years, getting fish, all of it.

    I wish I had a better life and wasn't FUCKING CRIPPLED by my mental issues.

    if I keep talking its just going to be about suicide so I'm going to go try and distract myself. Fuck I hate emotions and crying. Just please I need life to be alright

    CW reddit transphobia debate brosI dipped back into reddit recently with some of the Australian trans stuff and it was a bad idea for my mental health, I've logged myself out on all my screens.

    But it's fascinating how poorly convincing the trolls were. I'd say something like "oh are you a woman?" or "this is why women are afraid of YOU", and I got like 5 or 6 replies, saying "oh I actually am a woman", and by the time I'd get to them they'd already have deleted as if they knew even with hidden comments it wouldn't bare up under mod or admin scrutiny.

    And another time I said I'd spent a lot of time reflecting on my lesbian identity. And someone said "Lesbians don't have to reflect on their identity, they are just women who are attracted to women" and I was like "honey you've never met a lesbian in your life? They're all reflecting on their lesbian identities, as ex-straight or bisexual or late in life or whatever"

    I need fantasy books that go all out on magic technology.

    Like why are mfs fighting with swords and staffs? Where's my drone swarms? Magic artillery/ICMBs? Assassinations by telephoning poison into your enemy's wine? Automated magic artifact production factories?

    Why is a world with magic got miners using pickaxes? Where's my magic smart tablets inscribed with speed casting runes? What about huge alchemical processing facilities that pump gigatonnes of philosopher's stone fluid into the wizard economy?

    I know there's probably some books like that (I've even read one but won't recomend the series cause it got wierd in that horny middle aged Japanese writer way if you know what I mean).
