Cells

Front 1

Tiny cell structures that carry out specific functions within the cell; their name comes from a word meaning "little organ"

Back 1

Organelles

Front 2

A rigid layer of nonliving material surrounding some types of cells; in plants it provides structure and support; this structure is not found in animal cells or some protist cells

Back 2

Cell Wall

Front 3

Controls what substances come into and out of a cell; surrounds the cytoplasm of all cells

Back 3

Cell Membrane

Front 4

The cell's control center, directing all of the cell's activities; "you're in Domain Eukarya if you carry a _____ in your cells"

Back 4

Nucleus

Front 5

A membrane surrounding the nucleus; materials pass in and out of the nucleus through pores in this structure

Back 5

Nuclear Envelope

Front 6

Thin coiled strands containing the hereditary material known as DNA; found in the nucleus, it contains the cell's genetic instructions

Back 6

Chromatin

Front 7

A sphere-shaped object located inside the nucleus; it is where ribosomes are produced

Back 7

Nucleolus

Front 8

Gel-like fluid in the cell found between the cell membrane and the nucleus; this surrounds the organelles and contains many of the chemicals needed by the cell

Back 8

Cytoplasm

Front 9

"Powerhouses" of the cell; they convert energy in food into a form the cell can use called ATP

Back 9

Mitochondria

Front 10

A maze of passageways in the cell found just outside the nucelus; it allows transport of proteins and other materials from one part of the cell to another

Back 10

Endoplasmic Reticulum

Front 11

Small grainlike structures that produce proteins; some are attached to the endoplasmic reticulum and others float in the cytoplasm

Back 11

Ribosomes

Front 12

Receive proteins and other materials from the endoplasmic reticulum; they are small flattened sacs and tubes that package materials into membranes for distribution within or out of the cell

Back 12

Golgi Bodies

Front 13

Large green structures that capture light energy for storage in food molecules; used for photosynthesis, they are only found in plant cells and some protist cells

Back 13

Chloroplasts

Front 14

Store food, water, waste, and other materials needed by the cell; most plants have a large one of these located in the center of the cell for storing water

Back 14

Vacuoles

Front 15

Small, round structures containing chemcials that break down certain materials in the cell; they break down large food molecules into smaller ones, and recycle old cell parts

Back 15

Lysosomes

Front 16

Cells that are different from one another, enabling each type to perform specific jobs; they are found only in multicellular organisms and combine to form tissues

Back 16

Specialized Cells

Front 17

A group of similar cells that work together to perform a specific function; several types of these combine to form organs

Back 17

Tissues

Front 18

Made of different kinds of tissues that function together; they make up organ systems

Back 18

Organs

Front 19

A group of organs working together to peform a major function; multicellular organisms may be made of several or more of these
