This really is of no consequence. I've just always wondered. It's so cool looking.

They're sleeping.

JK...

I think it might have to do with respiration.

nothing wrong with waking up early atleast you get home early too. (well minus my days in the refinery, wake up at 4, start at 7:00 end at 5:30, sleep at 7 pm, repeat 4x)

back on topic, it is to conserve water and heat. Why would it do it to conserve water in an aquarium? well most plants are actually non-aquatic, so they retain their behaviour under water.

How it is done is like hydraulics, pushing or pulling in liquid into cells to move

"Most plants are non aquatic" is just not true. Some are, but its not like you could drain your aquarium and have your plants live.

And why would they conserve heat? Aquariums are same temp all day...

Lets see some evidence...

during photosyntheses, leaf surfaces exposed to light expand as
thousands of stomata pores allow O2/Co2 gas exchange to occur,
thus leaves will arc out when lit, then tighten back up at night.
thicker more rigid leaves will not noticeably bend by this activity.

Yeah, though why would they need to close their stomata if they're underwater? Cause most plants on land close it to conserve water, and open to let out o2 and let in co2, so I don't see a reason they need to close it.

Lets see some evidence...

Most aquatic plants that we have in our tanks can be grown emerged. You could drain your tank and seal it tight to keep up the humidity
And most of your plants should grow.

Plants that can grow emerged. Thats alot of plants

I remember a long time ago I had an argument with one of my biology teachers back in high school about if aquatic plants had stomatas or not. She said all plants do and I said only terrestrial plants do.

It turns out we were both wrong. Only some aquatic plants are completely lacking stomatas while some only produce them when they are close to the surface and is in contact with the air.

Also there are other aquatic plants that are full of stomatas for passive diffusion of water flow that rarely closes them.

Here are some of the examples.

This is some kid's project but it explains the difference between photosynthesis and respiration.

plants respire at night too. Remember that it takes in O2 at night.
