What structural characteristics do cells share?
Nucleus
Cytoplasm
The nucleus and cytoplasm is contained within what, inside a cell?
Cell membrane
What does a cell membrane do?
Regulates what’s passes in and out the cell
What does a nucleus contain?
Chromosomes
Nucleolus
What’s are the chromosomes?
The cells generic material
What does nucleolus produce?
Ribosomes
The contents of the nucleus ( nucleolus and chromosomes ) is contained by what?
Nuclear membrane
The nucleolus produces Ribosomes? What do ribosomes produce? And how are they packaged?
Produce: Proteins
Packaged by the Golgi apparatus so the can leave the cell.
What does a cytoplasm consist of?
Fluid and organelles ( which can be considered as the cells organs )
What does a endoplasmic reticulum do?
Transports materials within the cell
What does a Mitrochrondria generate?
Energy for the cells activities.
Lysosomes contain what?
Enzymes that break down particles entering the cell.
Centrosomes composed of two centrioles participate in what?
Cell division
How is DNA prepared in cell division?
DNA is copied and condensed into two sister chromatids.
What’s are chromatids?
Two identical chromosomes temporarily held together before cell divides
