This document provides a review of key cell biology concepts including:
1. It defines important cell structures like the cell membrane, nucleus, mitochondria, chloroplasts, and vacuoles.
2. It explains cellular respiration takes place in the mitochondria, with oxygen and sugar as inputs and carbon dioxide, water, and ATP as outputs.
3. It notes that a cell's shape is related to its function, giving the example that form follows function.
1. Cell Unit Review
Vocabulary:
Cell: BasicUnit of life
Bacteria:Verysmall single celledorganismswithNOnucleus.
Microbe:Creaturesthatyou can onlysee witha MICROscope.
Magnify:To make biggeror enlarge
Organelles:Tinyorganswithinthe cell, the partsof the cell
Mitochondria:Organelle thatproducespower/energyforthe cell
Chloroplast:A plantorganelle thatallowsthe cell tophotosynthesize tomake foodforthe cell.
Cell membrane:Organellethatcontrolswhatentersandleavesthe cell andgivesthe cell shape.
GeneticMaterial: DNA locatedinthe NUCLEUS, computercode/instructionsforthe cell
Nucleus:Controlsall cell activities,isconsideredthe “brain”of the cell.
NuclearMembrane:Surroundsthe cell andprotectsthe geneticmaterial inthe nucleus.
Protists:Single celled/multi-celledorganismsthathave anucleusandare notanimal,plantor fungus.
(Example:Amoeba(bloblike),Paramecium(ciliahairs) ,Euglena(whiptail) )
Vacuole:Storage bubble withinthe cell.
Cytoplasm:Jellylike material thatfillsthe cell. All otherorganellesflotinthe cytoplasm.
Multicellular:Manycelledorganism (MOSTlivingthings.)
2. Unicellular:One celledorganism(Amoeba,Bacteria,Yeast)
