Cell Parts Flashcards
Cell membrane
Phospholipid bilayer
Let’s things in and out
Nucleus
Spherical lipid membrane that contains DNA
Holds DNA and controls cells activity
Produces ribosomes
Ribosomes
Made of RNA
Thousands per cell
Found in all cells
Build proteins from amino acids
Rough ER
Folded lipid membrane attached to nucleus
Has ribosomes
Protein production proteins travel through folds
Smooth ER
Second part of ER of folded membranes
Produce new lipids
Nuclear envelope
Lipid bilayer surrounds the nucleus
Contains nuclear pores
Chromatin
Inside nucleus
Nucleolus
Dark part where ribosomes are made
Cytoplasm
Everything between nucleus and membrane
Golgi
Lipid folds
Packaged and shipped
Lysosomes
Vesicles w/ enzymes
Digest
Cell suicide
Mitochondria
Bean shaped with internal membranes
Cellular respiration
Chloroplasts
Green beans w/ internal membranes
Turn light energy into food- photosynthesis
Endosymbiotic theory
Plastids and mitochondria are the descendants of once free living prokaryotes that were internalized by a larger cell
How stuff moves in cell
Nucleus RER (ribosomes) SER --transport vesicle Golgi Lysosomes Mitochondria ATP
Cytoskeleton
Cell skeleton to maintain shape and size
Thin fibers
Microfilaments made of actin used for cell movement a muscle contraction
Larger fibers
Macrotubules
Hollow tubes make of
Tubulin
Grow from centrioles
Position of nucleus determines
Cell shape and location of cilia and flagella
Centrioles
Responsible for division of chromosomes during cell division and the cytoskeleton
