Plant cell structure and functions Flashcards
important of cells
a. all organisms are made out of cells
b. the cell is the simplest collection of matter that can live
who is regarded as the inventor of useable tow-lensed microscope; study about cells; coined the term ‘cell’
Robert Hooke
first identified and name the cell’s nucleus
Robert Brown
(who) all plant tissues are composed of cells and that an embryonic plant arose from a single cell.
Matthias Schleiden
(who) all cells are the structural units of life
Theodor Schwann
(who) all cells come from pre- existing cells
Rudolf Virchow
cell theory ( 3who’s)
Matthias Schleiden, Theodor Schwann, Rudolf Virchow
to study cells, biologist use _____ and the tools of biochemistry; provide window to the world of cells
microscopes
scientist use microscope to visualize cells to small to see with the naked eye
Microscopy
two types of cells make up every organism
prokaryotic and eukaryotic cell
basic common features among all cells:
a. they are bounded by a plasma membrane
b. they contain semifluid substance called the cytosol
c. They contain chromosomes
d. They all have ribosomes
kingdoms of eukaryotic
Multicellular, Eukaryotic (Plantae, animalia, fungi)
Kingdoms of prokaryotic
Unicellular, Prokaryotic ( Eubacteria, Archabacteria)
Eukaryotic, unicellular and multicellular
Protista
A typical rod-shaped bacterium; do not contain nucleus; have their DNA located in a region called Nucleoid.
Prokaryotic cells
Prokaryotic cells: attachment structures on the surface of some prokaryotes
Pill
Prokaryotic cells: region where the cell’s DNA is located ( not enclosed by a membrane)
Nucleoid
Prokaryotic cells: organelles that synthesize proteins.
Ribosome
Prokaryotic cells: membrane enclosing the cytoplasm
Plasma membrane
Prokaryotic cells: rigid structure outside the plasma membrane
cell wall
Prokaryotic cells: jelly-like outer coating of many prokaryotes
Capsule
Prokaryotic cells: locomotion organelles of some bacteria
Flagella
a plant cell; contain a true nucleus, bounded by a membraneous nuclear envelope; are generally quite a bit bigger than prokaryotic cells
Eukaryotic cells
Dna: Naked, circular, no introns
Prokaryotes
