Chapter 3 Parts of the Cell Flashcards
Define Organelle
membrane-bound with internal compartments with specialized functions.
Organelles are
Nucleus
Endoplasmic Reticulum
Golgi apparatus
Lysosomes
Mitochondria
In the organelle (nucleus) what does it contain? and protects?
It contains our DNA (instructions for building proteins) and it protects DNA
In ribosomes what do they make? and structure?
make polypeptide chains,
structure has 2 subunits
Nuclear envelope
Double membrane (2 bilayers) surronds nucleus
Nucleoplasm
area inside the nucleus
Nucleolus
dense area in the nucleus, where ribosomes are produced.
Rough Endoplasmic
reticulum
Newly made poly peptide
chains are folded into
proteins and a
carbohydrate chain may
be added
Smooth Endoplasmic
reticulum
Phospholipids and
steroids are made here.
Contains enzymes that
detoxify alcohol and
some drugs
what structure builds the polypeptide chains/proteins?
Ribosomes
where are polypeptide chains/proteins folded?
Rough Endoplasmic Reticulum
What organelle produces energy for the cell?
Mitochondria
What type of cytoskeleton is a cilia made of?
Microtubules
What type of cytoskeleton divides the cytoplasm during cell division?
Microfilaments
What type of cytoskeleton is involved in creeping movement, including making incoming vesicles during endocytosis?
Microfilaments
