trans women love getting their chloroplasts

The Leaf Sheep is a 5mm sea slug that steals chloroplasts from algae and keeps them alive in its own tissue, photosynthesizing sunlight into food. Only a handful of animals on Earth can do this.

Leaf sheep (Costasiella kuroshimae), a species of sea slug, retains the chloroplasts from algae they graze on to perform photosynthesis, a process known as kleptoplasty.

While both nori & wakame are edible seaweed, they are separated by >1 billion (!) years of evolution. Nori is red algae, which acquired its chloroplasts via primary endosymbiosis; wakame is brown algae, which acquired its chloroplasts from another algae. They are about divergent as human vs yeast.

Remarkable paper explaining how sea slugs maintain chloroplasts obtained by kleptoplasty active for many month & eventually digest them for resources www.cell.com/cell/fulltex...

photosynthesis requires the forced labour of chloroplasts within the cells, and it is still unclear whether chloroplasts have truly been given the choice to do this work

they have been captured, much like mitochondria, for eons and never given the chance to be liberated
photosynthesizing is the only ethical action under capitalist hegemony
I thought cooking at home was fascist last week. I guess I'll have to learn to photosynthesize

Like... look at this idiot! Check out this rejection of biology! This moron has chloroplasts and you don't! This is my new animal fixation for at least 6 months.

Diatom Guinardia flaccida (background removed). This is such a pretty diatom, with its star-shaped chloroplasts. 🦑

A group of Japanese researchers confirmed that Rapaza viridis, a eukaryote, sends proteins derived from its own genes to chloroplasts it takes from green algae to have them then conduct photosynthesis.
Japanese researchers find a clue to the evolution of chloroplasts
Their research on a single-celled eukaryote called Rapaza viridis provides a clue to unraveling the evolution of chloroplasts, according to the group.

Plant cells can be filled with chloroplasts, as shown in this image of moss gametophore phyllid ("leaf") cells. These cells have not been stained with fluorescent dyes; we only observe the autofluorescence of chloroplasts (green 🟢) and of the cell walls (magenta 🟣)

A two-shelled snail that turns green because it's absorbing chloroplasts from the algae that it feeds on.

'Life,' as the famous scientist said, '... uh... finds a way.'
We’ve looked at snails with one shell and slugs with no shells. Now let’s have a look at a snail with two shells, because Nature laughs at our puny attempts to pigeonhole.

In today’s #AtoZ – J is for Julia (Juliidae) (1/9)

Costasiella sea slugs showcase their brilliant green, plant-like appendages. Through these miniature marvels "steal" chloroplasts to perform photosynthesis.

the only ethical food source is to bioengineer yourself chloroplasts and photosynthezie, and fruit

Here are some “leaf” or phyllid cells from moss Physcomitrium patens gametophore. Cells are expressing a green fluorescence marker that labels the vacuolar membrane. Chloroplasts' autofluorescence is in magenta.
Can you spot dividing chloroplasts?

This second event occurred when more advanced cells absorbed cyanobacteria. Cyanobacteria can harvest energy from sunlight and they eventually become organelles called chloroplasts that can harvest energy from sunlight. The chloroplasts gave us another core principle of biology-

Many members of the sacoglossan sea slug family are adapted to a kleptoplastic lifestyle, allowing them to (inefficiently) photosynthesize for brief periods when food is scarce.

But turning an animal cell into a plant cell is not a trivial task. Plants are specially adapted to keep chloroplasts.
Photosynthesis: On the art of stealing chloroplasts
Sea slugs increase the longevity of the chloroplasts they steal from algae by limiting the harmful side-effects of photosynthesis.
