Biology Ii, Chapter 3, Cell Structure And Function

Front 1

Short cylinders that contain fine tubules called microtubles

Back 1

centriole

Front 2

Within the nucleus are masses of threads and they are referred to what?

Back 2

chromatin

Front 3

Rod-like structures that masses of chromatin condenses to just prior to cell division

Back 3

chromosome

Front 4

Plasma membrane extensions that contain microtubles are called what?

Back 4

cilia

Front 5

The substance of the cell outside the nucleus is called what?

Back 5

cytoplasm

Front 6

Plasma membrane extensions that contain microtubles. Used for locomotion.

Back 6

flagella

Front 7

Organelle that consists of concentrically folded membranes and that functions in the packaging and secretion of cellular products

Back 7

Golgi apparatus

Front 8

Organelle involved in intracellular digestion; contains powerful digestive enzymes

Back 8

lysosome

Front 9

organelle in which cellular respiration produces the energy molecule ATP

Back 9

mitochondrion

Front 10

Two layers of phospholipids with proteins randomly embedded in it. Selectively permeable. Controls the transport of materials in and out of the cell. Functions in recognition, communication, and hoeostasis.

Back 10

Cell Membrane

Front 11

Membraneous tubular canals, that start outside of the nucleus and branch through the cytoplasm. Allow an increased surface area for chemical reactions. Creates lipids, phospholipids, and cholesterol. Detoxifies drugs, and chemicals in the cell.

Back 11

Smooth Endoplasmic Reticulum

Front 12

Membraneous tubular canals. Make protein for cell. Transporation of protein.

Back 12

Rough Endoplasmic Reticulum

Front 13

Small organelles made of RNA and protein. Not covered by a membrane. Two main subunits made in nucleus then sent to cytoplasm. Site of protein synthesis. Free in cytoplasm - makes protein for the cell. On ER - makes protein to be exported out of the cell.

Back 13

Ribosomes

Front 14

Small membrane-bound sac. Stores substances within a cell. Used for transportation and storage of materials.

Back 14

Vesicles

Front 15

Membrane bound sac. Holds fluid and other substances. May store food, wastes, etc.

Back 15

Vacuoles

Front 16

double membrane surrounding nucleus that has nuclear pores allowing substances to pass through or out of the nucleus. Continuous with the ER.

Back 16

Nuclear envelope/membrane

Front 17

found strictly in plants. It is a structure which supports the cell.

Back 17

cell wall

Front 18

turns sunlight, carbon dioxide and water into sugars and oxygen that are used in plants. Photosynthesis

Back 18

chloroplasts

Front 19

Contains DNA needed to create cells, and instructions to make copies of itself

Back 19

nucleus

Front 20

large protein complexes that cross the nuclear envelope, which is the double membrane surrounding the eukaryotic cell nucleus.

Back 20

nuclear pores

Front 21

structures with specialized functions, suspended in the cytoplasm of a eukaryotic cell.

Back 21

organelle

Front 22

They are long, thin, and stringy protein structures found in the cytoplasm of eukaryotic cells

Back 22

microfillaments/actin filaments

Front 23

major double-membrane organelle found, among others, in the cells of plants and algae, are the site of manufacture and storage of important chemical compounds used by the cell

Back 23

plastid

Front 24

nuclear subdomain that assembles ribosomal subunits in eukaryotic cells

Back 24

nucleolus

Front 25

stack of thylakoids within the chloroplast of plant cells.

Back 25

Granum

Front 26

The lattice or internal framework of a cell composed of protein filaments and microtubules in the cytoplasm, and has a role in controlling cell shape, maintaining intracellular organization, and in cellmovement.

Back 26

cytoskeleton

Front 27

membrane-bound compartment inside chloroplasts and cyanobacteria. They are the site of the light-dependent reactions of photosynthesis.

Back 27

thylakoid membrane

Front 28

filamentous intracellular structures that are responsible for various kinds of movements in all eukaryotic cells, are involved in nucleic and cell division, organization of intracellular structure, and intracellular transport, as well as ciliary and flagellar motility.

Back 28

microtubule
