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
