How do the finding of margulis and other scientists-that mitochondria and cholarplasts have third own DNA like a cell nucleus-support the hypothesis of endosymbiosis?
concept that mitochondria and chloroplasts are the result of years of evolution initiated by the endocytosis of bacteria and blue-green algae which, instead of becoming digested, became symbiotic.
What is the evidence scientists have to support endosymbiosis and the evolution of prokaryotes to eukaryotes?
The difference between eukaryotes and prokaryotes is primarily that prokaryotes don't have membrane-wrapped organelles, including a cell nucleus containing its genetic material and mitochondria, the organelles that produce most of the eukaryote's supply of ATP, a source of chemical energy for cells. It is thought that organelles like the mitochondria evolved in eukaryotes as a result of endosymbiosis between prokaryotes. A similar origin has been proposed for chloroplasts in algae and plants. This is supported by the fact that these organelles contain their own DNA, and replicate independently from the host cell, as well as by their apparent genetic, morphological and behavioural relationship with various extant prokaryotes.
Are cells limited in size by the amount of cytoplasm available to support the organelles and aid in nutrient transport?
no
How does the internal structure with these organelles support mitochondria and chloroplast's function?

What is the function of nucleouplasm?
Nucleouplasm is the fluid in the nucleus of cells that functions as a support for the organelles contained in the nucleus. It also helps to transport things throughout the nucleus.

After ln margulis's endosymbiont theory met oppositon what new evidnece emerged in support of the theory?
main distinction between euayotes and prokaryotes
Which 2 organelles help to support the plant cell?
Mitochondria & Chloroplasts

What maintains the cell shape anchors the organelles in place and move organelles of the cells?
The cytoskeleton of the cell, made of microtubules to move organelles, microfilaments to contract the cell, especially during cell division, and intermediate filaments to provide support and anchor the organelles, does all of these things.
What provides support and keeps organelles position properly inside the cell?
Cell Walls.
How do organelles in the animal cell work together to support life?
they each have a special job
What organelles help to support the plant and help it to maintain its shape?
Vacuole and Cell wall
Which organelles support life processes in plant cells but are not found in animal cells?
chloroplasts
What does the organelles do in the cell for the human?
organelles control, support, and supply the cell so it can survive. some organelle are the nucleus, mitochondria, vacuole, golgi apparatus, and endoplasmic reticulum.
Are cells limited in size by the amount of cytoplasm available to support the organelles and aid in nutrient transport?
no
What organelles help to support the plant cell and help it to maintain its shape?
Vacuole and Cell wall
