MODULE 3 Flashcards
what characteristics eukaryotes and prokaryote both have? (6)
flagella
plasma membrane
cell division
cytoplasm
ribosomes
chromsomes
domain eukaryota or _______ comes from the Greek eu, _______ and karyon, _______
eukarya,
“true” , “
nut” or “kernel“.
(eukaryotic cell structure)
gives strength and give shape to the cell
cell wall and pellicle
eukaryotic cell structure for Photosynthesis—trapping light energy and formation of carbohydrate from CO2 and water
chloroplasts
cell movement
Cilia and flagella
Environment for other organelles, location of many metabolic process
Cytoplasmic matrix
Transport of materials) protein , and lipid synthesis
Endoplasmic reticulum
Packaging and secretion of materials , lysosome formation
Golgi apparatus
Intracellular digestion
Lysosomes
Cell structure and movements, form the cytoskeleton (3)
Microfilaments, intermediate filaments, and microtubules
Energy production through use of the tricarboxylic acid cycle, electron transport, oxidative phosphorylation, and
other pathways
Mitochondria
Ribosomal RNA synthesis, ribosome construction
Nucleolus
Repository for genetic information, control center for cell
Nucleus
Mechanical cell boundary, selectively permeable barrier with transport systems, mediates cell-cell interactions and
adhesion to surfaces, secretion
Plasma membrane
Protein synthesis
Ribosome
Temporary storage and transport, digestion, water balance
Vacuole
Prokaryotes or procaryotes is coined from two Greek words pro_______, and karyon, ________
before, nut or kernel
used to describe unicellular (single-celled) organisms that lack true nucleus and membrane-bound cell organelles. This means that the genetic material is not bound within a nucleus.
Prokaryotes or procaryotes
Prokaryotes are divided into two domains
Bacteria and archaea
Common prokaryotic cell types (3)
cocci (spherical)
bacilli (rod-shaped)
Spirilli (spiral-shaped)
Structures that you can onIy find in either eukaryotic and prokaryotic cell but not in both
Nucleus - E
Cytoskeleton - E
Plasmid - P
• unicellular organisms without nuclei
• No organelles
• Have cell walls
• Lacks peptidoglycan
• DNA is more similar to eukaryotes, denotes lineage.
Archaebacteria
Archaebacteria live in extreme environments. (T/F)
Give examples. (3)
True
No oxygen,
Hot springs,
Deep ocean
Where do archaebacteria get energy?
Chemosynthesis
is the biological conversion of one or more carbon-containing molecules (usually carbon dioxide or methane) and nutrients into organic matter using
the oxidation of inorganic compounds (e.g., hydrogen gas, hydrogen sulfide)
or ferrous ions as a source of energy, rather than sunlight, as in photosynthesis.
