11) prophase
12)46
13)spindle fibers
14)the centriole basically helps split the cell by forming the spindle fibers which split the chromosomes in half
15)Prophase
16)honestly I'm confused as to what this is asking, spindle fibers?
17)well, plant cells have a cell wall and have a central vacuole, while animal cells lack both of these things.
18) Basically these three stages occur: g1; cell grows and sythesizes proteins s1:the cell creates dna g2: the cell preps for division
