endosymbiont theory
can someone explain what it means by infolded membranes?
"prokaryotes with infolded membranes were engulfed by other prokaryotes as the invaded prokaryotes plasma membrane folded inwards around the invading cell this produced the double membrane of what are now chloroplast and mitochondria"
i dont understand a single word can someone explain it?
thanks

Infolded membrane just means that. the cell-surface membrane of the prokaryote is folded inward (think of microvilli, but instead of pointing outward like they usually would, they point toward the middle of the cell). When a cell engulfs another, part of the engulfing cells membrane is broken off to form a vesicle that surrounds the engulfed cell, if the engulfed cell has a folded membrane and the vesicle that surrounds it is not folded, then the appearance of this vesicle will be similar to that of a mitochondrion (smooth outer membrane with a folded inner membrane).
