Cells Theory Flashcards
Are made up of small organ-like structures called organelles.
Cells
Who discover the cell in 1665
Robert hook
Who created a powerful microscope?
Anton van leeuwen hook in 1673
Discovered the nucleus in 1827.
Robert brown
A botanist who concluded that all plants are made of cells.
Matthias schleiden in 1838
A zoologist who concluded that all aninals are made of cells.
Theodor schwann 1839.
A physician who did research on cancer cells and concluded “omnis cellula e cellula”( all cells are form other pre-existing cells”.
Rudolph Virchow
Simple cells that do not have internal membranes
Prokaryotes
More complex cells that do have internal, membrane bound structures.
Eukaryotes
Control center for cell activities
Nucleus
Clear thick jelly-like fluid between the inside the cell membrane
Cytoplasm
Provides energy and power house of the cell
Mitchondria
Stores water, waste and other materials
Vacuole
Controls what moves in and out of the cell(takes in food/ gases &removes wastes.
Cell membrane
A ribosome that is responsible for protein synthesis
Ribosome
This is a group of flatten sacs that are near the endoplasmic reticulum.
Goji body
A vesicle is a structure which cintains a liquid(cytoplasm), enclosed by a layer of lipid
Vesicle
It has ribosome,. Transport protein and other materials
Rough Er
Does not have ribosomes
Smooth Er
Suicide sacks, they digest excess or wokn out organelles.
Lysosome
Contains chlorophyll, a green pigment that traps sunlight
Chloroplast
Rigid, outermost layer of the plant cell
Cell wall
It is one big sac that stores water to maintain turgor pressure
Vacuole
These are small sacs but with a largw number all work together to store waste material.
Vacuoles
Is a eukaryotic cell that contains a true nucleus and certain organelles to perform specific functuons.
Plant Cell
Is a type of cell that is seen specifically in animal tissue. It os characterized by the absence of a cell wall, woth cell organelles enclosed within the cell membrane.
Animal cell
Organelle is responsible for packing
Golgi apparatus
Houses the optical parts in the upper part of the microscope
Head/body
Supports the microscope and house the illuminator
Base
Connects to the base and support the microscope head.
Arm
Is what you look through at the top of the microscope.
EYEPIECE
Holds the eyepiece in place above to the objective lens
Eye tube
Are the primary optical lenses on a microscope
Objectives lenses
Houses the objectives
Nosepiece
Is where the specimen to be viewed is place
Stage
Are used when there is no mechanical stage
Stage clips
Is used to collect and focuse the light from the illuminator on the specimen.
Condenser
Controls the amount of light reaching the specimen
Aperture
To move focus
Coars focus
To adjust blur
Fine focus
Also referred to as a light microscope, is a type of microscipe that commonly uses visible light & a system of lenses to generate magnified images of small objects
Compound micrscope
