cell, tissue, organ, organism, organ system
cell, organ, organ system, tissue, organism
cell, tissue, organ, organ system, organism
organism, organ system, organ, cell, tissue
Students are observing a specimen under a microscope. The specimen is made of cells. They shine a bright light on the specimen and observe it slowly turning itself towards the light.
The specimen appears to be breathing.
The specimen under the microscope began to bubble.
When placed in pure water, the specimen seems to swell up, absorbing the water.
The specimen grows in size and develops colorful blooms over the several weeks in which it is being observed.
Which structure in the diagram to the above indicates that this must be a plant cell?
cell wall
cell membrane
nucleus
mitochondria
Which statement best describes models A and B above?
Model A is an animal cell and model B is a plant cell because model A contains a nucleus in the center of the cell and model B contains a nucleus near the edge.
Models A and B are both plant cells because they both contain a nucleus, mitochondria.
Model A is an animal cell and model B is a plant cell because model B contains chloroplasts and a cell wall, all of which model A does not have.
Models A and B are both animal cells because they both contain a nucleus and mitochondria.
Lysosomes are important organelles within a cell. What would MOST LIKELY happen if a cell’s lysosomes were not functioning properly?
The cell would create new lysosomes through cell division
The cell would be damaged by the waste buildup inside the cell
The cell would no longer receive the nutrients it needs to function
The cell would be less able to regulate substances entering and leaving the cell
Mitochondria are important organelles within a cell. What function do mitochondria have in a cell?
Mitochondria are the “powerhouses” that provide energy for the cell.
Mitochondria are the “bosses” of the cell.
Mitochondria are the storage parts of the cell.
Mitochondria make proteins in the cell.
This organelle creates maze like "roads" that are used to move proteins and other material. They also help ribosomes create proteins.
mitochondria
lysosomes
ER (endoplasmic reticulum)
cell membrane
Stores water, food, or other materials needed by the cell. It can also store waste until the waste is removed. In plant cells these are usually large but are found much smaller in animal cells.
vacuole
lysosomes
ER (endoplasmic reticulum)
cell membrane
A thin, flexible barrier that surrounds a cell and controls what things come in and out of a cell. The door of the cell.
vacuole
lysosomes
ER (endoplasmic reticulum)
cell membrane
Small round organelles that create proteins that do a lot of the work in cells. The factory.
vacuole
lysosomes
ribosomes
cytoplasm
