In animal cells, the centrosome has a pair of ________, each with nine triplets of _________ arranged in a ring.

500
What is the difference between primary and secondary endosymbiosis? (hint E.coli and mitochondria)
Primary endosymbiosis involves the engulfment of a bacterium by another free living organism. Secondary endosymbiosis occurs when the product of primary endosymbiosis is itself engulfed and retained by another free living eukaryote.

Define phagocytosis.
In phagocytosis, pseudopodia extend around the "food" that the cell is trying to engulf to form a vesicle around it.
