The main structural component of a plant cell wall is

cellulose

All cells have some characteristics in common; both prokaryotic and eukaryotic cells have

cytoplasm, a plasma membrane, and DNA.

A cell being observed under a microscope has a cell wall, plasma membrane, ribosomes, and chromosomal material that is not found in a nucleus. Based on this information, the cell could be a

bacterial cell.

Where do the vesicles that are being made for secretion from the cell become modified and packaged?

Golgi apparatus

Which of the following organelles would form a membrane-bound package, also known as a vesicle?

Golgi apparatus

Chromosomes are made from

NOT CELL RECOGNITION PROTEINS

Which of the following organelles is not surrounded by a membrane?

NOT chloroplast

Plant cells have plasmodesmata that

NOT resemble the cytoskeleton of animal cells

Which of the following is an incorrect match of molecule to the location where it is principally used?

glucose - lysosome

granum

What does the folding of the mitochondrial inner membrane provide?

greater surface area for ATP production

Carrie would like to observe the cilia on the surface of a live paramecium—a single-celled organism. The best device to do this would be a

light microscope.

In bacterial cells and plant cells, cell walls function in

maintaining cell shape.

Bacteria hold their DNA is region inside of their outer membrane. What is this region called?

Which feature is found in all cells?

plasma membrane composed of phospholipids

Plant cells can communicate with each other using what structure?

plasmodesmata

Both plants and animals need mitochondria to

produce ATP.
