biology chapter 7.3
TRANSCRIPT
What gives the cell structure:
Cytoplasm – the "fluid" that fills
the cell
Where all the chemical reactions
take place
Cytoskeleton – the structure
within the cytoplasm that holds
the organelles in place
Cell "Cookbook"
Nucleus – site of the DNA
DNA holds all the protein
"recipes"
Nucleolus – a place inside
the nucleus where
ribosomes are made
Endoplasmic Reticulum
Rough ER – rough because it has
ribosomes
Protein is made at the ribosomes
Smooth – no ribosomes
Complex carbohydrates, lipids and
phospholipids are made here
Golgi Apparatus – The UPS of the Cell
Packages, finishes and ships out
proteins
Hangs out next to the Rough ER
Vesicles – the protein sacs that
go back and forth between the
Golgi and the plasma
membrane
Endocytosis and Exocytosis
Active Transport of large molecules
Vacuoles: U-Store of the Cell
HUGE in plants
Small part of animal cells
Hold water, waste and other
useful materials (super
important to plants)
Lysosomes: Cellular Clean-Up Crew
Vesicles that contain
acids and enzymes that
go around finding things
to eat and digest like:
Waste
Bacteria
Viruses
Mighty Mitochondria
ATP maker
Powerhouse of the cell
Has lots of small folds called
cristae that help maximize the
space inside the tiny little
organelle
Chloroplasts (Plants Only)
Place where
photosynthesis takes
place
Chlorophyll – the
pigment that makes
plants green
