CELL THEORY Flashcards
dutch spectacle maker_______ made the first compound microscope
1590 Zacharias Janssen
examined the structure of thinly sliced cork under the microscope
1665 Robert Hooke
Publication of robert hooke
Micrographia
a dutch shopkeeper examined pond water and saw living organisms which are _______
1676 Anton Van Leeuwenhooek
protozoa and fungi
determined that all living plant tissue was composed of cells and that each plant arose from a single cell
1838 Matthias Schleiden
came to a similar conclusion to animals
1838 Theodore Schwann
________ and ______ researches became the bases of the first two postulates
Schleiden and Schwann
refined by him
all cells arise from cells
and that the cell was the basic unit of life
1858 Rudolf Virchow
he tried to prove the idea of cell division
1855 Robert Remak
3 postulates
All organisms are made up of cells
The cell is the basic unit of life
Cells arise from pre existing cells
selectively permeable
composed of a double layer of phospholipids
Cell Membrane
enclosed within the cell membrane
Cytoplasm
cytoplasm contains the semifluid substance called
Cytosol
helps in the separation and movement of the replicated genetic material
Centrioles
The replicated genetic material in centriole
Chromosomes
control center of the cell
Nucleus
whats inside the nuclear envelope
nucleoplasm
membrane-free organelle found inside the nucleus
Nucleolus
nucleolus contains the
fibrils and granules
helps in the assembly of proteins in the cell
Ribosomes
manufacture secretory proteins such as pancreatic cells
Rough ER
has no ribosomes attached
Smooth ER
modifies, packages and distributes molecules made at one location
Golgi Bodies
it has hydrolytic enzymes, proteins that use
water to break down substances
Lysosomes
produces ATP
Mitochondrion
ATP
adenosine triphosphate
energy currency of the cell
ATP
appendages responsible for locomotion of cells
flagella and cilia
______ moves in a whiplike manner
Flagellum
Euglena
_______require power and recovery stroke
Cilia
Paramecium
located outside the cell membrane, made of_______
Cell wall
Cellulose
maintains the shape of the plant
cell wall
composed of amino acids and sugars
Peptidoglycan
nitrogen containing polyssacharide similar to cellulose which serves as structural support
Chitin
a colorless fluid surrounding grana
stroma
inside this double membrane organelle
Chloroplast
occupies the largest space which is called ________
Central Vacuole
maintains turgor pressure
Vacuole
unicellular organisms that lack membrane bound structures
Prokaryotes
central region of the cell that contains its dna
nucleoid
responsible for protein synthesis
Ribosome
some bacteria have a layer if carbohydrates that surrounds the cell wall called the ________
capsule
thin, hair like strictures
Fimbriae
rod shaped structures involved in multiple roles
Pili
think, tail like structure that assist in movement
Flagella
organisms whose cells have a nucleus and other organelle
Eukaryotes
phospholipid bilayer that surrounds the entire cell
Plasma Membrane
gel like substance within the cell that contains the organelles
Cytosol
is an organelle dedicated to protein maturation and transportation
Endoplasmic Reticulum
membrane bound sacs involved in transportation and storage
Vesicles and Vacuoles
