Exam 3: Cells

Explain the process of filtration and give an example of a body process that depends on filtration.

Lysosomes are the "digestive bags" of the cell.

If the DNA code is adenine-thymine-guanine, the messenger RNA sequence would be

Both hyperplasia and hypertrophy can cause an increase in the size of a tissue or organ.

Match each organelle or cell structure to its corresponding function or description. -Organelle named as such because of the ribosomes attached to it

The simplest definition of dialysis is the diffusion of water across a cell membrane.

A gene and a nucleotide are the same thing.

If the DNA code is adenine-thymine-guanine, the transfer RNA code that would be called for would be adenine-uracil-guanine.

The nucleus is the only structure in the cell that contains DNA.

Which of the following is not part of the plasma membrane?

Match each organelle or cell structure to its corresponding function or description. -Small fingerlike projections in the plasma membrane that increase the efficiency of absorption of materials into the cell

Osmosis and dialysis are both specialized examples of diffusion.

DNA replication occurs during which phase?

What is meant by specific base pairing?

The cell membrane is able to efficiently move material because each ion pump can move a number of different substances.

Explain the role of ion pumps in both cystic fibrosis and cholera.

Explain the functioning of an ion pump, and give an example of one in the plasma membrane. Why are they considered active transport mechanisms?

In anaplasia, cells fail to mature normally and do not differentiate as they should.

What is the movement of water from an area of higher water concentration to an area of lower water concentration through a selectively permeable membrane?

Match each phase of the cell life cycle to its corresponding description. -The chromosomes are aligned in the middle of the cells
