The nucleus has a membrane called the…
Nuclear envelope
It has holes called…
Nuclear pores
Which let certain substances in and out. What does the nucleus store?
DNA
What is made in the nucleus which is let out?
RNA and ribosomes
Nucleus
Plants, Animals
Where are ribosomes made?
Nucleolus, part of the nucleus
What do ribosomes make?
Proteins
What are the “instructions” that ribosomes follow?
RNA
Where (two places) are ribosomes found?
Cytoplasm, Rough ER
Ribosomes
Plants, Animals, Bacteria
What makes the rough ER “rough?”
Ribosomes
What does the smooth ER do?
Makes lipids, detoxifies chemicals, stores ions
Endoplasmic reticulum (ER)
Plants, Animals
What does the Golgi apparatus do?
Sorts and packs
Golgi apparatus
Plants, Animals
Vesicles
Plants, Animals
What are vesicles?
Small blobs of membrane which carry substances
Lysosomes
Animals
What do lysosomes do?
Digest food, recycle damaged organelles
What do lysosomal enzymes need to function?
Acid
Endomembrane system
Nucleus, ER, Golgi, Vesicles, Lysosomes
What is the general function of the endomembrane system?
Make and transport proteins
Mitochondria
Plants, Animals
What is the function of the mitochondria/what do they do?
Make energy using cell respiration
What characteristics of the mitochondria help us understand that they used to be free-living organisms?
Have own DNA, ribosomes, have two membranes
Chloroplast
Plants
What is the function of the chloroplast?
Photosynthesis
What makes chloroplasts green?
Chlorophyll
Central vacuole
Plants
What does the central vacuole store?
Water, toxins, pigments, wastes
Cytoskeleton
Plants, Animals, Bacteria
What does the cytoskeleton do?
Supports shape of cell, helps it move
Centrioles
Animals
What do centrioles do?
Help organize cell division
Cilia/flagella
Animals, Bacteria
What do cilia and flagella do?
Help cell move
What is the major difference between cilia and flagella?
Many small cilia, usually one or a few large flagella
