CELL STRUCTURE AND FUNCTION Flashcards
(23 cards)
study of cell, its structure & function
cytology
who stated that all plants are composed of cells
Matthias Schleiden
who stated that all animals are composed of cells
Theodore Schwann
who stated that all living cells come from pre-existing living cells by the process of cell division
Rudolf Virchow
parts of the cell
that serves as boundary between the environment & the internal part of the cell
cell membrane
colloidal substance of a cell
protoplasm
a thick colorless liquid in the cell in which various organelles are suspended
protoplasm outside nucleus
cytoplasm
protoplasm inside nucleus
karyoplasm/nucleoplasm
where cellular respiration takes place
mitochondria
act as digestive system of the cell
lysosomes
mass of dense protoplasm with s structure called centriole
centrosomes
act as a pole for cell division
centrioles
prepare proteins for secretion after they are released from the endoplasmic reticulum
golgi bodies
serve as a pathway for the transport of materials between cytoplasm & the nucleus
endoplasmic reticulum
protein factories of the cell
ribosomes
food & water storage of the cell
vacuole
give the cell its shape/ cytoskeleton
microtubules
protects & supports plant cells not present in animal cells
cell wall
contains green coloring bodies called cholorophyll
chloroplast
semi-permeable membrane composed of lipids, proteins & carbohydrates
plasma membrane
control center of the cell
nucleus
cells without definite nucleus
prokaryotic
cells with definite nucleus
eukaryotic
