Exam 3: Cells

Chromatin forms during prophase of cell division.

The mitochondria is considered the "power plant" of the cell.

Carbohydrate chains in the cell membrane are used as identification tags for the cell.

Chromatin contains both protein and DNA.

During metaphase,chromosomes align in the center of the cell.

The main structural unit of the cell membrane is the protein molecule.

A cell put in a hypotonic solution would lyse.

The nucleolus plays an important role in the formation of ribosomes.

Match each of the cell structures with its function or description. -Important in the formation of ribosomes

Because of complementary base pairing,if one side of a DNA molecule was ATCCGTAATC,the other side of the molecule would be

The organelles that are the "power plants" of the cell are the

Match each of the cell structures with its function or description. -Fluid in the cell between the nucleus and the plasma membrane

The DNA replicates itself during

Match each of the cell structures with its function or description. -"Brain" of the cell; controls all the cell's functions

The diffusion of water through a selectively permeable membrane is called dialysis.

Describe the structure of the plasma membrane.

Which organelle contains nucleic acids?

Small,hairlike structures on the exposed side of some cells are called the

Match each of the cell structures with its function or description. -Made up of phospholipids,cholesterol,and protein molecules

Cilia are small,fingerlike projections on the cell membrane that increase surface area and assist in absorption.
