How does the nucleus appear different in prophase compared with interphase?
The chromatin is visible in prophase and not so visible in interphase
100
When are the enzymes and other proteins needed for cell division synthesized and moved to proper sites?
Interphase- G2

How can you distinguish rough and smooth endoplasmic reticulum and golgi?
The rough ER is made of flattened inter connected sacs (typically right next to the nucleus) and is closely associated with ribosomes. Smooth ER is more tubular and is not associated with ribosomes. Golgi has stacked flattened sacs called cisternae.

How do the structures of cilia and microvilli differ and how do these differences relate to their function?
Cilia are hair-like projections. This allows them to move in a wave like fashion to move substances across the cell surface. Microvilli are finger-like extensions of the plasma membrane. They increase surface area and aid in absorption of materials into the cell.

Why is mitosis not considered cell division, but the mitotic phase is considered cell division?
Mitosis only includes nuclear division while the mitotic phase also includes cytokinesis which is division of the other organelles and cytosol.

What are the 3 things that can happen to a cell?
They can grow and divide, they can enter G0 and not divide, they can die (by apoptosis or necrosis)

What is the function of the many folds in the inner membrane of the mitochondria?
Increasing surface area.

What happens in the nucleolus?
Synthesis of parts of the ribosome

a) What are the two phases that are nearly opposites? b) Why are they considered nearly opposites?
a) peoples and telophase b) in prophase chromatin condenses, nucleoli disappears, and the nuclear envelope dissembles. while in telophase chromosomes revert to chromatin, nucleoli begins to reappear, and the nuclear envelope starts to reassemble
300
a) How is DNA replicated? b) what phase in the cell cycle does this occur?
a) There are many enzymes involved, but simply: the double strand is unwound and the two ends are filled in with nucleotides to synthesize two new strands. b) In interphase specifically- S phase (s for synthesis)
300
a) How does a centrosome related to a centriole. b) What are they made up of?
a) 2 centrioles make up one centrosome. b) microtubules

What is necrosis?
The pathological cell death due to injury

What do ribosomes consist of?
ribosomal RNA and protein

Trace the processes that occur to synthesize a protein and the organelles that theses processes occur within.
Transcription from DNA to RNA in the nucleus and translation of RNA to protein in the cytoplasm or rough endoplasmic reticulum
