Science 1.1

Produces powerful enzymes that aid in digestion and excretion of substances and worn out organelles

Organelle that processes and repackages proteins produced in rough ER for release at cell membrane

Network of tubes and flat, curved sacks that help transport materials through the cell; site of calcium storage; main location of fat metabolism

Makes enzymes that oxidize some toxic chemicals

Encloses contents of the cell regulating the flow of substances into and out of the cell

Folded membranes extending throughout the cell, studded with ribosomes; help transport materials through cell; site of much protein manufacture

Small structure that functions in protein assembly

Jelly like fluid in which organelles float; primarily water but also contains enzymes and amino acids

Provides support for the cell; sometimes linked to the cells outer membrane

Internal framework of the cell. Comprised of microfilaments and hollow microtubules

The fluid within the nucleus in which nucleolus and chromosomes float

A two layered membrane with pores through which substances enter and leave the nucleus

The cells control center. Containing chromatin and most of the cells DNA

The region at the center of the nucleus that plays an important roll in ribosome production

A sac that stores and transports ingested materials, waste products, and water

The site of fat and sugar digestion in the cell ; produces energy; power house of the cell

Part of the cells cytoskeleton; aid movement of substances through the watery cytoplasm

Complicated of two cylinders of tubules; essential to cell reproduction

Sac that contains various substances that is secreted at the cell membrane

Many molecules naturally move from an area where they are in high concentration to a lower concentrated area.

A carrier protein bonds with a specific molecule such as glucose, outside the cell, then changes shape and ejects the molecule into a cell

Molecules bind to a receptor site on the cell membrane, triggering a protein to change into a channel, through which molecules travel

A specialized part of a cell that has a specific function

A group of cells with similar structure that function together as a unit but at a lower level than organs.
