This cellular structure is responsible for making proteins that will be used either inside or outside of the cell. There are two types; free and bound. They receive their instructions from the DNA of the cell.
Smooth ER
Ribosomes
Rough ER
Golgi
This cellular structure acts as the gatekeeper of the cell. It protects the cell and determines what comes in and what goes out of the cell.
Cell membrane
Cell wall
Chloroplast
MItochondria
This organelle is found in plant cells, but not in animal cells. It uses sunlight, water, and carbon dioxide to make sugars to be used for food in a process called photosynthesis.
Cell wall
Central Vacuole
Mitochondria
Chloroplast
This organelle makes lipids and helps to detoxify the cell of poisons and drugs.
Smooth ER
Rough ER
Golgi
Mictochondria
New properties that arise as you move up through the levels of organization of life.
Emerging diseases
Emerging properties
Emerging viruses
Emerging biology
This organelle is responsible for receiving, modifying, and packaging products coming from the ERs to prepare them for export from the cell. Biomolecules like proteins enter the cis or back of this organelle and then leave through the trans or front of this organelle.
Smooth ER
Rough ER
Mitochondria
Golgi
This structure is found in plants, but not in animals. It is used to store water, nutrients, pigments, and toxins for the plant until they are needed.
Cell wall
Central vacuole
Chloroplast
Mitochondria
The magnification of the ocular lens of a light microscope is 10X. The magnification of the medium objective power lens is 15X. What is the total magnification of the scope while using the medium objective power lens?
1,500 X
15 X
5 X
150 X
This type of microscope gets its name because it utilizes 2 lenses and light to magnify and illuminate the specimen being viewed.
compound light microscope
scanning electron microscope
transmission electron microscope
This type of microscope gets it name from the fact that it shoots beams of electrons out to scan the surface of a specimen.
compound light microscope
scanning electron microscope
transmission electron microscope
This type of microscope gets its name from the fact that it shoots beams of electrons through a thinly sliced specimen to allow the inside of the specimen to be seen in fine detail.
compound light microscope
scanning electron microscope
transmission electron microscope
(a) is the quality of clarity or the distance between points in the image.
(a) is the quality of the ratio of the object's image size to its real size.
(a) is the quality of detail that can be seen under certain lighting conditions.

Identify three differences between prokaryotic and eukaryotic cells.
pro are large and euk are small cells
pro are small and euk are large cells
pro no nucleus and no organelles ; euk have nucleus and organells
pro unicellular and euk unicellular and multicellular
pro multicellular and euk unicelluar and multicellular
Cytoplasm is
the boundary that surrounds the cell to protect it
everything inside the cell; cytoplasm and cytosol
just the liquid inside; cytosol
only the organelles in the cell
Cytosol is
the boundary that surrounds the cell to protect it
everything inside the cell; cytoplasm and cytosol
just the liquid inside; cytosol
only the organelles in the cell
