Cell Transport Quiz Flashcards
Example of a prokaryote
Bacteria
Prokaryote vs eukaryote
Pro: no membrane bound organelles No nucleus Unicellular only Eukaryote: membrane bound organelles Nucleus Unicellular or multicellular Both: microscopic size, cytoplasm & cell membrane
Main difference between prokaryote & eukaryote
Prokaryote cells are simple while eukaryote cells are complex
Example of a eukaryote
White blood cell
Difference between animal and plant cells
Animal- circular shape, no cell wall chloroplasts or central vacuole
Plant- rectangular shape
Cell wall- outside cell membrane & ridged shape (protects the cell)
Chloroplasts-photosynthesis
Central vacuole- contains H2O, enzymes give the shape of the cell and eliminate waste
Define Nucleus
In an eukaryotic cell, membrane bound organelle which contains DNA and role in processes like metabolism
Define central vacuole
Large fluid filled organelle that stores water; enzymes, metabolic wastes, and other materials
Define cell wall
Ridged structure that surrounds the cell membrane & provides support to the cell, outside cell membrane
Cytoplasm
Region of the cell within the membrane that includes fluid, cytoskeleton, and all organelles except nucleus
Cell membrane
Cells outer boundary where all materials enter or exit
Let’s in, let’s out
Cytoskeleton
Network of protein filaments and tubes, essential role in cell movement, shape, and division
STRUCTURE
Vesicles
Small cavity sac, forms when part of the cell membrane surrounds the materials to be taken into the cell/ transported within the cell
Lysosomes
Cell organelle which contains digestive enzymes and buds from the Golgi apparatus
Ex. Breaks down old cell parts
DESTROY OR BREAK DOWN “stomach”
Smooth endoplasmic reticulum
Transition point for vesicles
Ex. Liver cell @ SER detoxifies cell
Brain cell @ SER tells to make
