Front 1

centriole

Back 1

found in cells of animals and some algae and fungi;two pairs of centriole's play an important rolein cell reproduction.

Front 2

chloroplast

Back 2

double-walled organelle found in plants and in some algae;funtions in photosynthesis to trap light in energy

Front 3

chromatin

Back 3

dense mass of material within the nucleus that is composed of individual chromosomes.

Front 4

chromosome

Back 4

structure that carries the genes;composed of proteins and DNA

Front 5

cilia

Back 5

flexible projections extending outward from a cellthat enable locomotion by whiplike motionof the cilia

Front 6

cytoplasm

Back 6

substance containing by living cells that is composed of a complex mixture of enzymes,sugars,and amino acids;these substance are constantly involed in chemical reactions.

Front 7

endoplasmic reticulum

Back 7

network of interconnected structures found in all eukaryotes;functions include intracellular transport of proteins and the breakdown of harmful substances.

Front 8

eukaryote

Back 8

cell containing a nuclear membrane and a membrane-bound nucleus;the vast majority of living organisms(for example,plants,animals,protist,and fungi)are eukaryote

Front 9

flagella

Back 9

long,whiplike strands extending from a cell that enable a cell locomotion.

Front 10

Golgi body

Back 10

flattened,saclike organelle that functions as a processing,packaging,and delivery system in eukaryotes

Front 11

lysosome

Back 11

organelle containing digestive enzymes that break down food and digest worn out cell parts.

Front 12

metabolism

Back 12

sum of all chemicals reactions that occur in cells;hydrolysis is one such chemical reaction

Front 13

microfilament

Back 13

structure of the cytosketeton in eukaryotes;composed of actin and myosin,it provide structural support and assist cell movement(for example,muscle movement.)

Front 14

microtubule

Back 14

structure of the cytoskeleto in eukaryotes that helps certain organelles move within the cell.

Front 15

mitochondria

Back 15

organelles,bound by a double membrane,found in all eukaryotes;mitochondria break down organic moecules to realse energy for cell reactions.

Front 16

nucleoli

Back 16

prominent bodies found in in the nuckleus of eukaryotes; the site of RNA synthesis

Front 17

nucleus

Back 17

control area of eukaryotic cells;contains chromatin and nucleolus

Front 18

organ

Back 18

a group of different tissues that work together top carry out a particular function; the stomach is an example

Front 19

prokaryote

Back 19

cell that lacks a membrane-bound nucleus and membrane-bound oragnelles; bacteria are prokaryotes.

Front 20

ribosome

Back 20

oranelle composed of RNA and protein;site where protiens are made from amino acids.

Front 21

lysosome

Back 21

organelle containing digestive enzymes that break down food and digest worn out cell parts.

Front 22

metabolism

Back 22

sum of all chemicals reactions that occur in cells;hydrolysis is one such chemical reaction

Front 23

microfilament

Back 23

structure of the cytosketeton in eukaryotes;composed of actin and myosin,it provide structural support and assist cell movement(for example,muscle movement.)

Front 24

microtubule

Back 24

structure of the cytoskeleto in eukaryotes that helps certain organelles move within the cell.

Front 25

symbiosis

Back 25

living together of twodissismilar organisms for their mutal benefit

Front 26

system

Back 26

group of organs that depend on other organs to complete a biological process such as digestion, respiration,or reproduction

Front 27

tissue

Back 27

in multicellular organsims,a specilized group of cells with the same basic structure that perform the same function

Front 28

vacuole

Back 28

membrane-bound,fluid structure functioning in storage,digestion,and maintenence of osotic balance.
