Anatomy and Physiology Study Set 1

The basic framework of a cell membrane is a triple layer of lipid molecules.

The genetic material (DNA) is the component of the cell that carries hereditary information.

A lysosome is an example of a cellular organelle.

Mitochondria manufacture proteins.

In anaphase of mitosis, centromeres and duplicated parts of chromosomes separate.

A cell that secretes abundant proteins, such as a cell in the pancreas secreting insulin, would have extra nuclei.

A structure that transports secretions from the rough ER to the Golgi apparatus is a vesicle.

The Golgi apparatus contains DNA.

An organelle that is a fluid-filled sac with inner partitions studded with enzymes is a mitochondrion.

Interphase is a "time out" in the cell cycle, when the cell rests its synthetic activities.

In osmosis, water diffuses down its concentration gradient.

A bone cell and a nerve cell have the same genetic information.

The movement of molecules from an area of low concentration to an area of high concentration is called diffusion.

A microfilament is made of tiny rods of actin protein.

Too infrequent cell division can lead to cancer, whereas too frequent cell division can delay wound healing.

During the metaphase of mitosis, chromosomes line up between the two centrioles.

Specialized structures within cells are called organelles.

A neuron and an astrocyte can descend from the same progenitor cell.

In terms of cell lineages, a blood cell is more closely related to a bone cell than to a skin cell.

The three-dimensional form of a cell affects its ability to perform its function.
