GEN BIO NEW LESSON 1 Flashcards
most important distinction among groups of living things
difference between prokaryotic and eukaryotic organisms
Deriving from the name itself, eu means “” while karyon means “” and pro means “_”
TRUE
NUCLEUS
BEFORE
chromosomes are enclosed inside the nucleus
EUKARYOTIC CELLS
while prokaryotes’ DNA is found in a region called the nucleoid, which has no membrane
PROKARYOTIC CELLS
a semi-rigid cell wall is present and membrane-bound organelles with specialized functions are absent
PROKARYOTIC CELLS
get the energy they need to grow and maintain normal cellular function through cellular respiration.
EUKARYOTIC AND PROKARYOTIC ORGANISMS
Cellular respiration has three main stages:
GLYCOLYSIS, THE CITRIC ACID CYCLE, AND ELECTRON TRANSPORT
cellular respiration reactions take place within the mitochondria
EUKARYOTIC CELLS
cellular respiration occur in the cytoplasm and/or within the cell membrane
PROKARYOTIC CELLS
Cells contain _ and _
DNA & RNA
the genetic information necessary for directing cellular activities
DNA and RNA
DNA and RNA are molecules known as _.
nucleic acids
are unicellular or single-celled organisms are the earliest and most primitive forms of life on Earth.
PROKARYOTIC CELLS
They are much simpler in cellular structure
PROKARYOTIC CELLS
may occur singly, in pairs, chains, cluster, aggregates, or colonies.
PROKARYOTIC CELLS
