Unit 2 Concept 1 - Cell Theory and Organelles Flashcards
cell theory
all living things are made of cells
cells are the basic unit of life
all cells come from other cells
unicellular
composed of one cell
multicellular
composed of many cells that may organize into tissues, organs, and organ systems
prokaryotic
no nucleus
no membrane-bound organelles
binary fission division
unicellular
cell walls
bacteria
eukaryotic
nucleus
membrane-bound organelles
mitosis division
uni/multicellular
only fungi and plants
animals, plants, fungi, protists
all cells have…
genetic material
cytoplasm
cell membrane
ribosomes
animal cells in eukaryotic
centrioles
lysosomes
cilia
flagella
plant cells in eukaryotic
chloroplast
center vacuole
cell wall
organelles
Subcellular structure that has 1 or more specific jobs to perform in the cell
phospholipid bilayer
proteins, carbohydrates, fluid mosaic model, hydrophilic head, hydrophobic tail
cell membrane
controls what goes in and out
cytoskeleton
structure support
cytoplasm
holds everything in place
nucleus
protects DNA
nucleolus
protects rRNA
ribosomes
makes proteins
smooth ER
makes lipids
rough ER
packages proteins
vesicle
transports proteins around the cell
golgi apparatus
get vesicles of protein from ER
lysosome
breaks down dead stuff
vacuole
storage
centrioles
helps cell division, pulls chromosomes apart
cilia
move fluid across
flagella
moves entire cell
mitochondria
breaks down chemical energy
chloroplast
where photosynthesis happens
cell wall
protects/maintains shape
proteins
embedded for transport
lipids
hydrophilic head and hydrophobic tail
carbohydrates
embedded for structure
