Organelles
Write your response as 1, 2, 3 or 3, 1, 2, etc.
Put the following items in order of size from smallest to largest:
1) Protein, 2) rough ER, 3) Ribosome
1) Protein
3) Ribosome
2) rough ER
All organisms are either prokaryotic or ...
Eukaryotic
Transport that does not require energy.
Passive transport
Active transport moves large molecules across the cell membrane using this macromolecule.
protein (pump)
Which TWO organelles provide evidence for the Endosymbiotic Theory?
mitochondria and chloroplasts
This organisms have a nucleus that stores their DNA.
The movement of molecules from high concentration to low concentration
Diffusion
the bulk transport of materials OUT of a cell
Exocytosis
Name an organelle with its own circular DNA, ribosomes, and a double membrane.
Mitochondria or chloroplast
These organisms have ribosomes and circular DNA but no membrane-bound organelles like a chloroplast.
Prokaryotes
Diffusion of water
Osmosis
This process forms a vesicle from the cell membrane, which buds inwards and brings many things into the cell.
Endocytosis
Macrophages are immune cells that digest bacteria and dead cells. To perform this action, they must have many of which organelle?
Lysosome
These cell-like systems have either DNA or RNA. They must rely on a host cell to reproduce. They are not usually considered to be alive.
Viruses
The movement of molecules across a membrane with the help of a channel protein. Does not require energy.
facilitated diffusion
If a solution has 20% salt, and the cytoplasm of a cell has 20% salt, this solution can best be described as...
Which organelles are involved in protein synthesis and secretion? Name three of the six.
nucleus, endoplasmic reticulum, ribosomes, golgi apparatus, vesicles, cell membrane
These organisms have a nucleus and a cell wall but do NOT have chloroplasts. They are more closely related to animals than to plants.
Fungi
Provide two examples of molecules that move easily through a cell membrane.
oxygen and carbon dioxide
If a solution has 20% salt and the cytoplasm of a cell has 5% salt, how can the solution be described? AND what is the fate of the cell?
hypertonic; the cell shrivels because water LEAVES the cell and moves towards the higher salt concentration
