<u>Endosymbiotic theory</u> explains the origin of chloroplasts and mitochondria and their double membrane. Mitochondria of eukaryotes evolved from aerobic bacteria living within their host cell and the chloroplasts of eukaryotes evolved from endosymbiotic cyanobacteria.
On the other hand according to the <u>autogenous hypothesis, </u>mitochondria and chloroplasts have evolved within the protoeukaryote cell by compartmentalizing plasmids or vesicles of DNA within a pinched off invagination of the cell membrane.
<u>Endosymbiont theory </u>is the theory that suggests that simple prokaryotic cells were engulfed by larger prokaryotes 1.5 billion years ago.
<u>Autogenous theory</u> is a theory that was proposed as an alternative to endosymbiont theory. proposes that eukaryotic organelles formed by infolding of the plasma membrane.
<u>Horizontal gene transfer theory</u> is an alternative to endosymbiont and autogenous theories for the origin of complex organelles in eukaryotes.
Yes. With the help of every individual organelle in the cell's body, a cell can keep itself alive. For example, they can use cellular respiration to create ATP.
The blackberry is an example of an aggregate fruit. These are made by the merger of several ovaries, while simple fruit is made by just one. Other fruits from this fruit type are raspberry and dewberry.
I would say no because hormones usually travel long distances via blood. This question makes it seem like it is short distance and does not talk about how the secreted entity travels. So my bet is no.
