Cell Theory
How did scientists first see cells?
Light/compound microscope
Which cell (prokaryotic or eukaryotic) has a nucleus?
eukaryotic
Which cell (plant or animal) has a cell wall?
plant
What is the function of the nucleus?
contains the DNA
What is the entire cell membrane made of?
phospholipid bilayer
What are the oldest cells on Earth?
prokaryotic cells
Give two examples of a eukaryotic cell.
plant, animal, fungi, protist
True or false. Both plant and animal cells have a cell membrane.
True
What is the function of mitochondria?
makes ATP
What type of transport is diffusion?
passive transport
Name one scientist who first saw cells through a microscope.
hooke, leeuwenhoek
Give an example of a prokaryotic cell.
bacteria
What is the function of a chloroplast in a plant cell?
site of photosynthesis
makes proteins
What type of transport are exocytosis and endocytosis?
active transport
Who came up with the cell theory?
Schwann
Where is DNA is a prokaryotic cell?
free floating
What is the function of lysosomes in animal cells?
contain enzymes (digestion and waste removal)
What is the function of the golgi apparatus?
sorting and packaging
Large molecules are moving with the concentration gradient. Which type of transport is this?
facilitated diffusion
What are the three parts of the cell theory?
all living things are made from cells
cells are the basic unit of life
cells come from other cells
What three things do ALL cells have?
cell membrane, ribosomes, cytoplasm
Describe the vacuole in a plant cell AND describe the vacuole in an animal cell.
plant cell has one large vacuole
animal cell has many small vacuoles
What is the function of the vacuole?
storage
Describe the differences between active and passive transport.
active uses ATP (against gradient)
passive does not (with gradient)
