Only one large one in plant cells vacuole small organelle, moves material within a cell vesicles consists of microtubules (made from proteins) that help shape and support the cell cytoskeleton liquid material within a cell cytosol refers to cytosol and the structures within the plasma membrane of the cell cytoplasm has ribosomes on the surface, comprises the transport system rough er does not have ribosomes on surface, comprises the transport system smooth er structure generates atp, cellular differentiation, cell cycle and cell growth regulation. numerous in eukaryotes (animal cells) mitochondria contains chromosomes and passes on genetic traits (DNA) nucleus chromosomes rods of DNA the dna and proteins that make up chromosomes chromatin within the nucleus, involved in protein synthesis, and synthesizes and stores RNA nucleolus encloses the structures of the nucleus, made from lipids nuclear membrane involved in the exchange of material between the nucleus and cytoplasm nuclear pores liquid within the nucleus ANAPHASE chromosomes start to pull away from each other (daughter chromosomes TELOPHASE spindle disintegrates, nuclear membrane reforms, chromosomes revert to chromatin.
