Bio 110 Quiz 2

Front 1

Lysosome

Back 1

I’m known as the “suicidal sac” of the cell, I digests/breaks down cell debris and other waste materials

Front 2

Cell theory

Back 2

1) all (living) organisms are composed of 1 or more cell

2) cell - basic structural and functional unit of life

3) cells arise only from division of preexisting cells

Front 3

Cell types

Back 3

Prokaryotic and eukaryotic

Front 4

Prokaryotic

Back 4

1st type, bacteria, no membrane bound nucleus, genetic material (single circular dna molecule), in nucleoid -> DNA concentration

Front 5

Eukaryotic

Back 5

True nucleus enclosed by membranes, many organelles, plasma membrane forms boundaries, found in fungi, protists, animals, plants

Front 6

Mid 1600s

Back 6

Robert Hooke - coined "cell"

Front 7

Cellulae

Back 7

Latin, "small rooms" by observing a thinly sliced cork from mature tree under light microscope

Front 8

Anton van Leeuwenhoek

Back 8

Observed animalcules, first to observe and create real microscope

Front 9

Matthias Schleiden

Back 9

1838, german botanist speculated nucleus - development of cell

Front 10

Theodore Schwann

Back 10

1839, german zoologist, expanded Schleiden's idea (all animals and plants are composed of cells and nucleus)

Front 11

Rudolf Virchow

Back 11

1850s, german physiologist, cell growth and reproduction(cells arise from pre existing cells through division)

Front 12

Cytoplasm

Back 12

Where main life activities occur, distribution of materials, where organelles are suspended, complex fluid that fills cell

Front 13

Plasma membrane

Back 13

Selective, regulates entry and exit, flexible and permeable

Front 14

Nucleus

Back 14

Control center, coordinates and redirects activities

Front 15

Nuclear membrane

Back 15

Double layered membrane, pourous, separates nuclear content from cytoplasm

Front 16

Mitochondrion

Back 16

(Mitochondria) pOwerhousE, energy production in metabolism, produces ATP (adenosinetriphosphate)

Front 17

Vacuole

Back 17

Membrane bound and fluid filled storage

1 big in plants, many small in animals

Front 18

Golgi apparatus

Back 18

Modifies, packs, sorts excretory materials, short parallel cavities of flat sacs

Front 19

Lysosome

Back 19

Digest/break down cell debris smaller to mitochondria, suicidal sac

Front 20

Endoplasmic reticulum

Back 20

Smooth and rough ed, tubes/ cavities, network of pathways, materials flow through cytoplasm

Front 21

Rough ER

Back 21

Network of interconnected membranes, ribosomes in process of synthesizin protein

Front 22

Smooth ER

Back 22

Lipid synthesis, metabolism, detoxifying

Front 23

Chloroplasts

Back 23

Photosynthesis, absorb light in conjunctionw/ water and C02 for plants

Front 24

Chloroplasts

Back 24

Surrounded by double membrane, slack of thylakoid membranes

Front 25

Ribosomes

Back 25

Protein factories, attached or free

Front 26

Cell wall

Back 26

Made up of cellulose, plant cells (outer layer)

Front 27

Cytoskeleton

Back 27

Stable dynamic network of protein fibers that give cell support and structure

Front 28

3 types of cytoskeleton

Back 28

Microtubules, intermediate filament, microfilament

Front 29

Centrioles

Back 29

2 small rods that align at right angles toward each other, each rod surrounded by microtubules
