Exam 6: Cell Structure and Internal Compartments

All of the energy in the food we eat is produced when organelles in plants called ____________________ convert the energy in sunlight to chemical energy.

Certain cells found in humans are identical to certain cells found in plants.

Membrane-enclosed structures in eukaryotic cells are called ____________________.

Which of the following would be the best analogy for the function of the Golgi apparatus?

The smooth endoplasmic reticulum

Microtubules are responsible for

When looking through a light microscope at a plant leaf, you notice small green organelles moving around in the cytoplasm of every cell. What organelle are you most likely seeing?

The contents of cells are often visualized with fluorescent (glow-in-the-dark)stains. You treat a cell with a stain that makes a certain part of the cytoskeleton glow green and another stain that makes mitochondria glow red. Under the microscope you see a meshwork of green filaments throughout the cell. Red organelles appear to be traveling along the filaments. The green stain you used must stain

The ____________________ found in eukaryotic cells have cristae.

Multicellularity does not characterize all types of organisms living today; which eukaryotic kingdoms retain unicellular representatives?

In the chloroplast, pancake-like membranes known as ____________________ are arranged into stacks of grana.

Which of the following statements is true?

The part of the plasma membrane that is in contact with the external environment of the cell consists of

____________________ pinch off from a membrane, enclose material, and then fuse with another membrane to release their contents at their destination.

The ____________________ model describes the plasma membrane as a mobile mixture of phospholipids and proteins.

Which of the following statements is false?

Mitochondria produce most of the energy used in a bacterial cell.

The word fluid in the term fluid mosaic model refers to the fact that

Volvox, the multicellular green alga shown below, has flagellated cells on its surface cells but not on interior cells. How might this condition develop?

What components of the plasma membrane of an animal cell would you find at its innermost surface, directly exposed to the cytoplasm?
