Chloroplasts in close-up

A vivid exhibition of chloroplasts making use of cytoplasmic streaming (cyclosis) to move to optimum position within the cell, for maximum light absorption used in photosynthesis process. The rate of motion is usually affected by light exposure, temperature, and pH levels.
These organelles are observable as flat discs usually 2 to 10 micrometer in diameter and 1 micrometer thick. A typical cell contains about 10 to 100 chloroplasts. The video is in real time.
Aquatic plant Egeria densa (or Brazilian elodea).

i just found this out recently, apparently, chloroplasts are ancient cyanobacteria with seperate DNA to the plant that contains them, which were "trapped" by plants millions of years ago, which now, of course, live in perfect symbiosis. Did anyone else know that? I didnt :) (You may have to check my facts xD)

exactly,yes, but there is one very important difference between the two, the chloroplast system use water as the electron donor while mitochrion uses molcular oxygen as the final electron acceptor, so this places the mitochondreal ancestors in a far modern time than that of those for chloroplast. actually the mitochondrael ancestors might have came into being because of the abundance of oxygen made available by the hydrolytic photosynthetic process of the ancestors of chloroplast, amzing !!!

need to talk about chlorophyll and chloroplasts just not pictures, but really cool video

[Tengo528]

its cool but they just show the same thing over again like 100 times

[claremaugeri]

cool !! keep safe god bless

[DarthMeg]

Wicked.

@merajrezvi thats just common sense stop trying to sound clever

[Danielst16]

That is very true another example of this is the mitochondria in animals which make ATP were the same deal, where they used to be bacteria that helped to provide energy for organisms and which have stayed with us through evolution, now they are less like bacteria but still have a lot of similarities.

Woouw nice cyclosis we have here

Pretty close, they were trapped by protobiont cells, not plants. Plants are a relatively "new" kingdom compared to the age of pre-photosynthesis. Not everything that photosynthesizes is a plant :)
