lysosomes
Electron microscopes show that animal and plant cells have organelles. The same microscopes show that bacteria do not have organelles.
Alfred Wegner developed the theory of plate tectonics, not a theory of a shrinking Earth. The Earth is not shrinking and no scientific theory has ever proposed that it is.
true
the organelles are enclosed in membranes
The physical mass of Earth isn't changing. The amount of habitable land is shrinking due to rising seas & advancing deserts.

true
the presence of organelles like the lysosome and the mitochondrion which both have double membranes. this suggests that these organelles were once free-living organisms that were incorporated into a larger organism in what could be called a mutual symbiosis.
their genes
Primary evidence consists of items that can be measured directly. If temperature readings are taken in the middle of a city for years and they keep increasing, that is primary evidence that the temperature is increasing in that city. If recent pictures taken of ice in Antarctica, Greenland, and the Himalayas are compared with those taken a century ago, they show the glaciers have decreased in size. That is primary evidence glaciers are shrinking. Any direct measurement is primary evidence.
Mid ocean ridge produce, deep ocean trench eat up. I knew this from my science, middle school.
The mitochondria. This organelle has it own circular DNA and make some of its own proteins. Strongly suggesting bacterial origins.
