Q.
has a nucleus and membrane bound organelles
33
30 sec
Q.
found inside the nucleus and produces ribosomes

powerhouse of the cell; organelle that is the site of energy production (cell respiration)
35
30 sec
Q.
transportation system of the cell that carries materials around the cell
36
30 sec
Q.
A structure in a cell that receives proteins and other newly formed materials from the endoplasmic reticulum, packages them, and distributes them to other parts of the cell.
37
30 sec

produce proteins for cell; found scattered in cytoplasm (fluid) or cell or attached to rough ER
38
30 sec
Q.
organelle containing digestive enzymes that breaks down molecules in cell

30 sec
Q.
organelle found only in plants; where photosynthesis occurs (capture sunlight and generate food source)
40
30 sec
