cell organelles Flashcards
Prokaryote
-no nucleus
-single loop of DNA
-few organelles
Eukaryote
-Enclosed nucleus
-DNA in chromosomes
-many organelles
Cytoplasm
jelly like substance that supports the organelles inside
Cell membrane
-enclosed cell contents
-contains DNA
-directs activities of the cell
Chromosomes
-DNA of eukaryotes is densely packed into chromosomes
-46 Chromosomes
Endoplasmic Reticulum
-serves as a system of channels from the nucleus
Rough ER
ribosomes attached to outside
Smooth ER
Lack Ribosomes
Golgi Apparatus
Collect, package, distribute molecules
Lysosomes
Break down food particles and old cells
Ribosomes
site of protein synthesis
Mitochondria
convert glucose to ATP
Chloroplasts (plant cell only)
chlorophyll absorbs sunlight and convert it to glucose
vacuole
animal-help sequester waste products
plant-water balance
centriole
partake in cell division
