Mitosis 1
What is the 1st phase of Mitosis?
Propase
What are organelles
"little organs" or parts that make up the cell
In which phase do the chromosomes line up in the middle?
Metaphase
What happens during the G1 phase?
cell grows
What are 5 levels of organization
Cell, tissues, organs, organ systems, organisms
What is the second phase of Mitosis?
Metaphase
What is a nucleolous?
forms ribosomal RNA that passes into the cytoplasm and becomes the site of protein synthesis; a mass largely of RNA
During which phase do chromosomes form in the nucleus?
Prophase
What happens during S-phase?
DNA is replicate/synthesized/copied
What would be the 8 levels of organization
Atoms, molecules, cells, tissues, organs, organ systems, organisms, populations
What is the third phase of Mitosis?
What do lysosomes do?
Memebrane-lined vats of enzymes (proteins) with capacity to digest microorganisms, damaged cell parts and ingested lysosomes.
During which phase, do the sister chromatin begin to get pulled apart to opposite sides of the cell?
Anaphase
What happens during M-phase (Mitosis)?
the cell divides
What type of reproduction is mitosis
asexual
What is the 4th phase of Mitosis?
Telophase
Site of protein synthesis
During which phase does the cell begin to tear apart and form two separate cells?
Telophase
What is not part of mitosis
interphase and cytokinesis
What is the longest phase of the cell cycle?
Interphase
What does PMAT stand for?
Prophase,Metaphase, Anaphase, Telophase
What does the cell membrane do?
It retains internal structure and permits exportation and importation of materials by in-folding and out-folding as in the formation of psedopods by white blood cells.
What is the purpose of mitosis?
Cell growth, repair
What is included in the cell cycle
Interphase, Prophase, Metaphase, Anaphase, Telophase, Cytokinesis
Oxygen “piggybacks” on red blood cells by using what protein
Hemoglobin
