Chapter Four Flashcards
Robert Hooke
discovered cells through looking in a cork;
Anton van Leewenhoek
first to look at living cells;
Matthias Scheldien
plants are made up of many cells;
Theodor Schwann
animals have many cells as well;
Rudolf Virchow
all cells come from preexisting cells
Cell wall
A rigid layer of polysaccharide around the cell membrane
Cell membrane
A semi permeable by layer of phospholipids that surround the cell
Nucleus
The structure that contains the chromosomes and DNA
Nucleolus
An area inside the nucleus that makes ribosomes
Ribosomes
Performs protein synthesis, made up of RNA and protein
Rough Endoplasmic Reticulum
Performs protein synthesis, has ribosomes attached to it, re-orders amino acids
Smooth Endoplasmic Reticulum
Produces lipids to create membranes, helps with detoxify the cell
Golgi Apparatus
Packages, modifies, and ships proteins
Mitochondria
Makes ATP through the breaking of thoughts
Lysosomes
Membrane bound, organelles filled with the digestive enzymes that break things down
Vacuoles
Storage within a cell
Vesicles
Helps transport and organized materials
Chloroplast
An organelle that produces sugar in ATP through photosynthesis
Cytoplasm
A jelly like substance that all organelles are suspended in
Cytoskeleton
Maintain cell structure, helps with transportation, and helps cell division
Cytosol
The fluid within cytoplasm that the organelles float in
Centrioles
Organizes the spinal fibers that perform cell division by pulling chromosomes apart
Eukaryote v prokaryote
You can have membrane bound organelles, while prokaryotes are less organized and more simple
