Which of the following is evidence to support the endosymbiotic theory?

Prokaryotes have the same number and types of enzymes as eukaryotes.

Mitochondria and chloroplasts have their own DNA, which is similar to prokaryotic DNA.

All eukaryotic cells have a double-layered membran composed of phosplipids and proteins.

Fossil evidence shows that the first forms of life were prokaryotic cells.

We know that endosymbiosis happened first with mitochondria and later with chloroplast. Why?

All eukaryotes have mitochondria including plants and algae, but only plants and algae have chloroplasts as well as mitochondria. This suggests, that the first eukaryotic cells first accquirred mitochondria and chloroplasts came later.

Mitochondria make energy and cells need energy more than the sugars produced by chloroplasts.

We actually do not know which one came first - this happened too long ago for us to know about.

Which of the following are evidence for the endosymbiotic theory. Select all that apply.

Chloroplasts and Mitochondria are about the same size as bacteria.

Chloroplasts and Mitochondria have their own DNA which is in a single loop just like the bacterial chromosome.

Chloroplasts and Mitochondria reproduce on their own independently from the rest of the cell.

Chloroplast and Mitochondria originated from in-folding of the plasma membrane.
