Exam 3: Cells

During anaphase,the chromosomes move away from the center of the cell.

Match the phase of mitosis with an event in that phase. -Chromatin condenses into chromosomes.

Cilia are hairlike structures on the free or exposed sides of some cells.

Explain how the DNA code controls the structure and function of cells.

Ribosomes contain ribose sugar.

Explain complementary base pairing.Why is this important for DNA replication?

If one side of a DNA molecule has a base sequence of TCA,the messenger RNA formed from that sequence would be UGT.

The ribosomes are the "power plants" of the cells.

Small,fingerlike projections of the plasma membrane that increase the surface area of the cell and make absorption more efficient are called

Robert Hooke named the small structures he saw "cells" because they reminded him of small monastery rooms.

Another term for tissue fluid is

A cell put in a hypertonic solution would crenate.

Which organelle is not found on the outer surface of the cell membrane?

If a 5% glucose solution were separated from a 10% glucose solution by a membrane that was permeable to both water and glucose

The following is not one of the main parts of a cell

List and give the functions of the organelles of the cell.

Cells are the smallest structural units of living things.

Protein synthesis consists of the process of

During periods of body growth,mitosis allows groups of cells to differentiate and become neoplasms.

The nucleolus is the "brain" of the cell; it directs all cell activity.
