Cells

All living things share some characteristics. For example, all organisms--

• are made up of one or more cells.

• make their own food from sunlight.

• have a skeleton to provide support.

• emerge at birth, from some type of egg.

Unlike prokaryotic cells, eukaryotic cells have their genetic material centrally located in a --

• chloroplast.

• vacuole.

• lysosome.

• nucleus.

Human beings share some characteristics with all other organisms. Humans, and all other living things,--

• communicate emotions through facial expressions.

• must consume other organisms for energy.

• are made up of one or more cells.

• require several years to reach maturity.

A eukaryotic cell can be distinguished from a prokaryotic cell because only a eukaryotic cell will have--

• DNA

• a cell wall

• a nucleus

• cytoplasm

In order to classify a cell as prokaryotic or eukaryotic, it must be determined if the cell--

• grows larger throughout its life.

• can move from place to place.

• is able to make copies of itself.

• has its genetic material in a nucleus.

Animal cells are considered eukaryotic and bacteria cells prokaryotic. This is because--

• animal cells grow at a much slower rate than bacteria cells.

• the cell membrane of an animal cell is much more rigid.

• animal cells require energy from outside food sources.

• the genetic material of the animal cells is stored in a nucleus.

What is one characteristic that all living things have in common? All living things--

• are made up of cells.

• eat food for energy.

• sleep for half of the day.

• reproduce by dividing entirely.

A chimpanzee and a pine tree have very little in common. However, because they are both living things, we can be certain that they both--

• use the sunlight to make their own food.

• travel with other members of the species.

• are made up of one or more cells.

• have a skeleton which allows them to move.

When comparing is a prokaryotic cell to a eukaryotic cell, an important difference is that the prokaryotic cell--

• is simple, performing limited function.

• is relatively small in size and unorganized.

• has its genetic information stored in the nucleus.

• has no structures that allow it to store food.
