Gap 0 (G0), Gap 1 (G1), S (synthesis) phase, Gap 2 (G2).
What are the 4 steps that Interphase can be divided into?
Gap 0 (G0)
Which stage is it, when latter is a cell that has reached an end stage of development and will no longer divide.
Gap 1 (G1)
Which stage is it when, cells increase in size, produce RNA and synthesize protein.
S (synthesis) phase.
DNA replication occurs in which stage?
Gap 2 (G2)
Which stage determines if the cell can now proceed to enter M (mitosis) and divide?
Mitosis Stage
Which stage does, cell growth and protein production stop?
Mitosis
Which stage does, cells in the body alternately divide?
Interphase
Which stage is it, when the cells "appear" to be resting?
Prophase
Which stage does, spindle fibers form, nucleolus fades, replicated DNA and associated proteins happen?
Metaphase
Which stage does, tension applied by the spindle fibers aligns all chromosomes in one plane at the center of the cell?
Anaphase
Which stage does, spindle fibers shorten, the kinetochores separate, and the daughter chromosomes are pulled apart and begin moving to the cell poles?
Telophase
Which stage does, the daughter chromosomes arrive at the poles and the spindle fibers that have pulled them apart disappear?
Cytokinesis
Which stage does, spindle fibers not attached to chromosomes begin breaking down, cytoplasm divides?
Hypotonic Solution
What solution, causes a cell to swell?
Isotonic Solution
What solution, doesn't change the shape of the cell?
Isotonic Solution
What solution, causes osmosis?
Hypertonic Solution
What solution, causes a cell to shrink?
Interphase
What phase does, cell growth occurs?
Mitosis
When does nuclear division occur?
Mitosis
When are chromosomes distributed equally to daughter cells?
Interphase
What stage is protein production is high?
Interphase
What stage are chromosomes duplicated?
Interphase
What stage does, DNA synthesis occur?
Mitosis
Cytoplasm divides immediately after what?
Interphase
What stage is the mitochondria and other organelles manufactured?
Active Transport
The is the movement of a chemical substance through a gradient of concentration or electrical potential in the direction opposite to normal diffusion, requiring the expenditure of energy?
Endocytosis
What is the process of cellular ingestion by which the plasma membrane folds inward to bring substances into the cell?
Facilitated Diffusion
What is the process of intercourse, a form of passive transport facilitated by transport proteins?
Exocytosis
What process is the cellular secretion or excretion in which substances contained in vesicles are discharged from the cell by fusion of the vesicular membrane with the outer cell membrane?
Passive Transport
What is the movement of a chemical substance across a cell membrane without expenditure of energy by the cell, as in diffusion?
Osmosis
Water across a selectively permeable membrane depending on the concentration of solutes on either side of the membrane, is what?
Isotonic Solution
What solution is the concentration of dissolved substances outside the cell is, the same as the concentration of dissolved substances inside the cell?
Hypotonic Solution
What solution is the concentration of dissolved substances outside the cell lower, than the concentration inside the cell?
Hypertonic Solution
What solution is the concentration of dissolved substances outside the cell higher than the concentration inside the cell?
The pressure decreases.
What happens to the pressure in Hypertonic Solution?
The cell swells.
What happens to the size of the cell in Hypotonic Solution?
