Mitochondria
The organelle that produces energy for the cell
Cytoplasm
The gel-like material found between the nucleus and the cell membrane
Exocytosis
The active transport process in which a cell forms and vesicle around a substance and takes it out of the cell
Vesicles
A membrane-enclosed sac used by the cell for storage and transportation of materials
Nucleus
The "control center" of the cell that contains all of the cell's genetic information
Golgi apparatus
The organelle that packages protein substances so that they can be shipped out of the cell
Diffusion
A passive transport process in which molecules move from an area of high concentration to an area of low concentration
Mitosis
A step by step process in which a cell prepares itself to divide into two identical cells
Filtration
A passive transport process in which the force of a fluid causes molecules to pass through the cell membrane
Endoplasmic Reticulum
A system of canals that are used to transport substances throughout the cell
Cytokinesis
The process in which the cell splits in two
Pinocytosis
The active transport process in which the cell forms a vesicle around a liquid or solute and moves in through the cell membrane
Nucleouis
The organelle located in the nucleus that is responsible for controlling protein synthesis
Osmosis
The diffusion of water through a selectively permeable membrane
Chromatin
The genetic material, composed mostly of protein and DNA, that makes up the nucleus
Lysosomes
Tiny sacs of enzymes that travel around in the cell getting rid of waste and other unwanted materials
facilitated diffusion
A passive transport process in which the molecules are helped through the membrane by way of a protein channel
Phagocytosis
The active transport process in which the cell forms a vesicle around a solid and moves it through the cell membrane
Organelles
Tiny cell structures that each have a specific function to perform
Endocytosis
The active transport process in which cells forms a vesicle around a substance and moves it into the cell
Ribosomes
The organelles that produce protein for the cell
Cytoskeleton
A thread-like network of fibers within the cytoplasm that gives the cell some framework and support
It only allows certain things through the membrane
What is meant by the term "selectively permeable"?
Metaphase
During which phase of mitosis do the chromatids attach to the spindles along the cell's equator?
Smooth E.R.
Which type of endoplasmic reticulum lacks ribosomes?
That way the chromatids have something to latch onto so they don't get lost
In prophase, why must the spindle fibers form before the nuclear membrane disappears?
Active transport
Which type of transport process requires the cell to use some of its own energy?
Centrioles
Spindle fibers between what two pairs of structures?
In the rough E.R.
Where in the cell would you find most of the ribosomes?
Chromatin
What condenses in the nucleus to form the chromatids?
Protein synthesis
What can take place in the rough E.R. That can't in the smooth E.R.?
The nuclear membrane
What must form around the chromatids before they can change back into chromatin?
They disappear
What happens to the spindle fibers and centrioles after the twin chromatids have moves to opposite ends of the cell?
Growing
What is the cell doing most of the time it's in interphase?
Cytoplasm, nucleus, and the plasmic membrane
And are three main parts of a typical cell?
Interphase, prophase, metaphase, anaphase, telophase
List, from first to last, the five phases of mitosis
