|
What are cells? |
Basic structural and smallest unit of life |
|
|
What are prokaryotic cells? |
Cells - more primitive than eukaryotes, have no true nucleus (instead a nucleiod), small ribosomes (70s) |
|
|
Universal organelles: |
Cell membrane, ribosomes, cytoplasm |
|
|
Prokaryote only organelles |
Pilli, flagellum, simple/slime capsule, plasmid, nucleiod, |
|
|
Eukaryote only organelles |
Vacuole, lysosome, centrosome, peroxisome, nucleus, nucleolus, endoplasmic reticulum, Golgi body, mitochondria, |
|
|
Plant only organelles |
Larger vacuole, chloroplast, cell wall |
|
|
Animal only organelle |
Centrosome, |
|
|
Golgi apparatus function |
Post office of cell, receives protein from E.R. Modifies protein with enzymes send protein to where needed in cell to repair damage |
|
|
Endoplasmic reticulum function |
Rough - has ribosomes, synthesizes protein, sends out to Golgi bodies in vesicles (sacs) Smooth - produces lipids, used to build cell membrane |
|
|
Nucleus function |
Manages and controls organelle and cell function, contains nucleolus (contains DNA) - contains information needed for cell to function and for cell reproduction |
|
|
Mitochondria function |
- power house of cell, breaks down nutrients with cellular respiration and provides energy for cell |
|
|
Types of biodiversity |
Genetic, species, ecological |
|
|
What is biodiversity |
The variation/diversity in all living organisms, any level of organization to organize and group species based on similarities, range of very broad group to more narrow/specific, found by Edward Wilson |
|
|
What is binomial system |
Identifying, classifying, naming species: to make universal name for species 2 names: Name 1 - genus name 2 - species Eg. Panthera Tigris By Carl Linnaeus |
|
|
Taxonomy |
Hierarchical classification of species : Domain, kingdom, phylum, class, order, family, genus, species (levels called taxons) found by Candolle Linnaeus - father of taxonomy |
|
|
Binary fusion |
Asexual, dna replicates (nucleiod) and cell splits into 2 cells found by Otto Hahn |
|
|
Bacterial conjugation |
Sexual, 1 pilli elongates and attaches to recipient cell, plasmid replicates and move to recipient cell, pilus removed, recipient becomes donor |
