Lab Practical #1

Nucleus

Stores DNA and turns it into mRNA

Nucleolus

makes ribosomes

Ribosomes

mRNA travels here and makes protein from amino acids

Golgi apparatus

Package protein and send it to the cell membrane

Cell Membrane

keeps fluids in the cell, maintains homeostasis

Lysosome

Digests proteins and gets rid of things cell does not need

Peroxisome

Detoxes the cell

Vacuole

Storage

Centrosome

Grabs genetic material and pulls it apart to start Mitosis

Cytoplasm

Cell fluid

Smooth ER

takes carbs and sugar and converts them to ATP(energy)

Rough ER

package protein and send to apparatus

Mitocondria

supplies ATP

transverse plane

plane that seperates superior and inferior

sagital plane

vertical plane up and down

frontal plane

horizontal across cranial view

midline

goes right down the front

lateral

side of body

proximal

closest to attatchment of midline

distal

further attached from the midline

cranial cavity

head/skull

dorsal body cavity

cranial cavitiy, throatic cavity, to diaphram

abdominal cavity

located below diaphram, conatins main organs

pelvic cavity

bottom cavity by private parts

throatic cavuty

contains upper respritory organs such as lungs, heart, etc

magnification

degree to which it is enlarged

resolution

ability to distinguish two close points as seperate

field of view

the area visible throught eh microscope

oscular lens

eyepiece lens 10x magnification

objective lens

lens closest to specien that provides magnification

parfocal

ability to remain in focus when switching objects

diaphram

controls amount of light reaching the specimen

condesender

focuses light onto specimen

working distance

distance between objective lens and specimen
