The tree would drown.
Trees require evaporation through the leaves to draw nutrient enriched water from the roots through the trunk to the leaves. Which then evaporates and causes the process to be continued.
They also require Carbon for the photosynthesis process, which trees absorb via the leaves in the form of Carbon Dioxide.

No such thing. Ask away!
!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must be legitimate questions. All post titles must include a question.
All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.
Rule 2- Your question subject cannot be illegal or NSFW material.
Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.

Second one is a little simpler, but the source link is to a site with open access educational materials. Pretty cool
What would happen then if you took a tree which only has leaves at the top and submerged it to just under the leaves? Does the bark need to be exposed to air as well or would it just rot out like timber does?
It would die. The roots need to do gas exchange too. Ideal soil composition is generally 45% mineral, ~25% water, ~25% air, and 5% organic matter.
Tree bark also does gas exchange.
Depends on the tree and type of water I assume

Mangrove trees live submerged in saltwater for example. This video also goes over some of the adaptations it has to do that (ex. Special roots to allow it to stand upright in soft unstable ground)
This is a mangrove, right?
Also aren’t there those alligator forests in America with lots of flooded trees.
Bayou is the word but those trees are usually only covered the first few feet by water unless it's flooding.
Alligator Forest is the new word, calling it.
I mean everyone knew exactly what he was talking about... and clearly not everyone knows what a bayou is, making "alligator forrest" the more universal term
So I know it’s not a tree, but how does algae survive underwater?
Algae can get by with dissolved gases in the water
Basically the same way, but instead of absorbing gasses through the air, it's through the water. They don't have stomata (air holes) that are found on plant leaves that exist on land and I believe they can absorb carbon directly through their cell walls.
It'll die, the leaves would turn into a slushie. The trunk would keep it's appearance underwater (logs are sometimes kept under water for processing.) And your whole aquarium would turn green from algae and mold pretty quick and you can't look inside anymore.
It would get wet.
Most likely tree dies and rots, it needs to exchange gasses with the atmosphere through the leaves
It may not rot. Depends on the water.
Tree gonna die though.
Heck, if the box was sealed, but not flooded, it’d probably die anyway.
Not if it was in the right balance. There's sealed terrariums after all.
"probably"... ;)
but, it's not just balance. the glass traps heat in, if the tree gets adequate sunlight, chances are, it'll overheat the tree.
( this guy is...kinda crazy... but, yeah. I like his stuff. )
The tree would die, it needs a combo of air, water, and sun to live.
Interesting sidenote to this tho, there is a hydroponic system called "kratky" where the plant roots go directly into a jar of water. As the plant grows the water level goes down, exposing more of the roots to oxygen, which is necessary for the plant to live/grow.
Your question isn't stupid, but it does make me feel very curious about what potential hypotheses you might have been weighing.
