Chapter 3
Label cell membrane
'"tails" of phospholipid, "heads" of phospholipid
What phase of mitosis occurs prior to telophase?
Anaphase
Controls passage of materials into and out of the cell
Cell membranes
Helps distribute chromosomes to new cells during cell division
Centrosome
Contains information for synthezing proteins
Chromatin
The first phase of the cell cycle is (BLANK) where the cell is actively growing and duplicating its contents and DNA.
Interphase
What makes up mitotic spindle?
Microtubules
Controls passage of materials between nucleus and cytoplasm
Nuclear envelope
Site of ribosome synthesis
Nucleolus
In (BLANK) the chromosomes complete the migration to the centrioles and the nuclear envelope reassembles.
Telophase
What is the result of mitosis?
Two identical daughter cells
In (BLANK) the spindle fibers shorten, splitting the sister chromatids and pulling them towards the centrioles at the opposite ends of the cell.
anaphase
The BLANK is a series of changes a cell undergoes from the time it forms until it needs to divide.
cell cycle
Glycoproteins (function/characteric)
cell identification
word means cellular, propels fluids across the cell surface, small hairlike extensions, found on cells of respiratory tract
cilia
The last phase of the cell cycle is (BLANK) where the cytoplasm divides and two identical daughter cells are formed.
cytokinesis
The products of the decomposition can diffuse out of the lysosome and into the (BLANK) or via the process called (BLANK) be removed from the cell.
cytoplasm, exocytosis
passive membrane transport (description)
diffusion, filtration, osmosis, movement with concentration radient, does not require cellular energy
moves the cell through the environment , found on sperm cells, motile extension
flagella
Genetic material from smallest to largest
genes, DNA, chromatin, nucleus
When cell division results in an increase in the overall number of cells, the result is called BLANK When cell division replaces worn out or damaged cells, it is called BLANK
growth, repair
Cell division must be controlled or regulated. In other words, only so many cells are needed to form organs such as the (BLANK) stomach, or brain.
heart
Phosphate head (function/characteristic)
hydrophillic outside
Fatty acid tails (function/characteristic)
hydrophobic inside
When completely surrounded, the microbe is brought (BLANK) the cell in a (BLANK)
into, vesicle
A (BLANK) fuses with the vesicle and its (BLANK) degrade and digest the microbe.
lysosmes, enzymes
Cholesterol (function/characteristic)
maintains rigidity
In (BLANK) the spindles attach to the chromosomes and the chromosomes are moved to the center of the cell.
metaphase
After the period of preparedness, (BLANK) begins. This time of the cell cycle is broken up into (BLANK) stages
mitosis, 4
nuclear enevelope
nuclear enevelope, nucleolus, chromatin, nuclear pores
A portion of the cells membrane projects (BLANK) to encircle the microbe.
outward
A (BLANK) a cell that can take in solid particles, encounters a microbe in the body.
phagocyte
In (BLANK) the chromatin fibers condense, making the individual chromosomes visible. Also during this phase, newly formed (BLANK)
prophase, centrioles
Membrane proteins (function/characteristics)
receptors, transporters
label composite cell
secretary vesicle, golgi apparatuas, lysosome, smooth endoplasmic reticulum, mitochondria, rough endoplasmic reticulum
During anaphase the mitotic spindles attached to chromosomes ___ while the unattached mitotic spindles ___ stretching the cell.
shorten: elongate
If cells divide too often, a (BLANK) may develop. If this unregulated growth spreads, or metastasizes, in the body it is called (BLANK)
tumor, cancer
active membrane transport (description)
uses cellular energy, pinocytosis, phagocytosis, endocytosis, exocytosis, sodium-potasssium pumps, movement against a concentration gradient
