Exam 4: Cell Structure

Photosynthetic bacterial membranes are located in the

Plant cells often have a large membrane-bound sac that is used for storing water and other substances.This organelle is called a

Mitochondria and chloroplasts are the other organelles besides the nucleus that contain

Lysosomes are vesicles bounded by membranes that contain oxidative enzymes.Their functions include all of the following except they

You have identified an enzyme that appears to be involved in the addition of palmityl group (a fatty acid)to certain proteins.Knowing that palmitoylated proteins are usually targeted to the plasma membrane,in which organelles might this enzyme be expressed?

Membrane-bound organelles that contain powerful enzymes found in cells are known as

One of the relationships that exists between ribosomes and lysosomes is that

Small cells function more effectively,because as cells become larger their surface area to volume ratio

Peroxisomes in animal cells,and glyoxosomes in plant cells are examples of

Flattened sacks of membranes apparently involved in the packaging and export of molecules synthesized in the cell are known as

The electron microscope can magnify an object typically

Chromosomes can be condensed into compact structures,visible with the light microscope,but usually only

In eukaryotes,mitochondria are the organelles primarily involved in

Who first described cells?

Plants,fungi,and bacteria share which one of the following characteristics?

A mutation in an integrin protein would likely affect all of the following except

The delivery system of eukaryotic cells called the ______ can collect,package,modify,and transport molecules.

The chromosomal hereditary material is packaged in this organelle in eukaryotic cells but not in prokaryotic cells.This organelle is

A distinctive feature of eukaryotes is the organization of their chromosomal DNA which is tightly packaged with proteins into a membrane-bound structure called a _______.

All _____ contain a plasma membrane.
