According to the endosymbiotic theory, infoldings in the cell membrane of an ancestral prokaryotic cell gave rise to endomembrane components, including the nucleus, endoplasmic reticulum and golgi apparatus in what would become eukaryotic cells. the evolution of endomembrane components provided for compartmentalization in eukaryotes, leading to more efficiency in cell processes. which part of the endomembrane system provides a mechanism for transporting proteins from the rough er to the golgi apparatus?
a) vesicle
b) lysosome
c) smooth er
d) peroxisome

A) vesicle

I think this is the right answer, i may be incorrect.

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
