Science Bio 1

Front 1

Electron Microscope

Back 1

Uses a beam of electrons, instead of light to produce an image. This way, no matter the thickness of the object, you can always see what is one the slide

Front 2

Compound Light Microscope

Back 2

(The ones we were using in class) is used by emitting light through the object in order to see it. If the specimen is too thick for the light to penetrate, no image will be seen in the microscope

Front 3

Steps to Prepare a Wet Mount

Back 3

1. Fixation (preserve)
2. Sectioning. (cutting thin sections)
3. Staining.(Apply dye)
4. Dehydration. (Immersed in ethanol - makes transparent)
5. Clearing. (ensures transparency)
6. Mounting (mounted on a microscope slide)

Front 4

Purpose of Stain

Back 4

To make a contrast between different specimens on the same slide (white vs red blood cells)

Front 5

Pasteur

Back 5

S shaped bend in a bottle - this proves that stuff can't just begin to grow from something spontaneously. There are microogranisms in the air

Front 6

Prokaryotes

Back 6

Cells without nucleus' - includes virus'. Very small.

Front 7

Eukaryotes

Back 7

Cells with nucleus', bigger, contains more organelles

Front 8

Cell Wall

Back 8

Found in a plant cell. Holds structure made of cellulose.

Front 9

Cell Membrane

Back 9

Found in both a plant and animal cell. Monitors what comes and goes out of the cell. Contains hydrophyllic and hydrophobic lipids and channel protein. It also communicates.

Front 10

Nucleus

Back 10

Control center of the cell - for DNA storage and reproduction

Front 11

Nucleolus

Back 11

Contains DNA and chromosomes

Front 12

DNA

Back 12

(Dioxyribonucleic Acid) it is the control panel of everything. Guanine, Cytosine, Adenine and Thymine

Front 13

Chromosome

Back 13

Parts of DNA that are used in the process of meosis and mitosis to ensure genetic variation within a person. 23 in each person

Front 14

Smooth Endoplasmic Reticulum

Back 14

Does not transport ribosomes but still moves molecules around (highway of the cell)

Front 15

Rough Endoplasmic Reticulum

Back 15

Transports ribosomes and protein (highway of the cell)

Front 16

Golgi Apparatus

Back 16

Post-man. Packages for distribution.

Front 17

Mitochondria

Back 17

Energy production (ATP) using cellular respiration

Front 18

Chloroplast

Back 18

Small disks where photosynthesis occurs.Contains chlorophyll.

Front 19

Vacuole

Back 19

Stores energy.

Front 20

Central Vacuole

Back 20

Large vacuole (takes up most of the plant cell) that stores energy

Front 21

Lysosomes

Back 21

Recycles and cleans up the cell

Front 22

Centrioles

Back 22

Releases spindle fibres in the process of mitosis and meiosis

Front 23

Ribosomes

Back 23

Makes proteins made from amino acids

Front 24

Cytoplasm

Back 24

Background-filler that holds everything together and also contains nutrients

Front 25

Main Differences Between Plant + Animal Cells

Back 25

Plants have chloroplasts, a cell wall and a central vacuole whereas Animal cells do not. Instead, animal cells have centrioles and just a normal vacuole and a cell membrane.

Front 26

Ribosomes

Back 26

the site for protein manufacture (located near endoplasmic)

Front 27

Pasteur

Back 27

Disproved spontaneous generation with an s-shaped bottle experiment.

Front 28

Theodore Shwann

Back 28

Stated that animals were made up of cells

Front 29

Matthias Schleiden

Back 29

Stated that plants were made up of cells

Front 30

Robert Brown

Back 30

Stated there was something called a 'cell'

Front 31

Rudolf Virchow

Back 31

Stated that cells can only come from pre-existing cells
