Both chloroplasts and mitochondria are like in that they both have nuclear membranes and their own blank

Endosymbiotic theory has it that both chloroplasts and mitochondria were once free living organisms which got taken into bigger cells - they provide the cell with energy, while the cell provides them with proteins and other things.

The two things this question ask about support that theory: chloroplasts and mitochondria are surrounded by a double membrane, which makes sense in that they kept their original membrane and the little bit of the cell's membrane when it engulfed them. And they have some of their own genetic material, though most of it is non-coding, which they have kept from the time when they were independent organisms. Hope that's helpful.

Wetlands form where water and land meet. a lake with a wetland fringe can fill in with decayed plant and animal material to become a wet meadow. a pond can fill in to become a bog or fen. sediment can fill in a river marsh to become a swamp.flooding of coastal lowlands from rising sea levels has created broad coastal marshes that are protected from wave action by barrier islands or reefs. coastal wetlands also form when rivers deposit sediment as they reach the ocean. plants then take root and hold the soil firm against the forces of tides and waves.

Atissue is a group of connected cells that have a similar function within an organism.
