This man observed cork with his microscope and called the tiny boxes 'cells'
Who was Robert Hooke
100

The smallest form of life

A cell

100
This fills the space inside a cell. It is semi-fluid and is composed of water and dissolved materials.
What is cytoplasm?
100
This organelle provides the cell with the ATP it needs to perform its functions and activities.
What is the mitochondria?
200

This cell type contains a nucleus and membrane-bound organelles (such as mitochondria).

What are eukaryotic cells?

200

Living things must maintain this

What is the homeostasis?

200
This organelle directs cell processes by providing DNA instructions. It is surrounded by its own membrane and is covered with pores.
What is the nucleus?
200
These structures are used for cell movement. The first is long and there are usually very few of them. The second are short and there are usually many of them.
What flagella and cilia?
300
Simple, compound, light, electron and transmission are all terms that relate to:
What are microscopes?
300

A worm turns away from light is an example of a worm

What is responding to its environment?

300
This organelle is a series of flattened membranes. Cell products pass through these membranes and become packaged for delivery in or out of the cell.
What is the Golgi apparatus
300
This organelle digests worn out cell parts and also plays a role to defend the cell from infection.
What is a lysosome?
400

This cell type has no nucleus or membrane-bound organelles. Bacteria are the only example of this cell type.

What is a prokaryotic cell?

400

Something that has never shown the characteristics of life and never will.

What is nonliving?

400
This organelle is a series of interconnected passageways. Proteins and lipids are synthesized (put together) here also. There are two varieties 'S' and 'R'.
What is the endoplasmic reticulum?
400
These are made by the nucleolus and their function is to follow DNA instructions to make stuff. They are free-floating or may be found attached to the ER.
What are ribosomes?
500

list each statement of the cell theory... list the 3 statements

1. All living things are made of cells. 2. Cells are the basic unit of life. 3. Cells only come from other cells.

500

When plants release oxygen as a byproduct of photosynthesis, they are exhibiting this characteristic of life:

What is exchanging materials with their environment?

500
This organelle is found only in animal cells. It is made of microtubules and is thought to play a role in cell division.
What are centrioles?
500
The three differences between plant and animal cells are:
1. Plant cells have cell walls. 2. Plant cells have chloroplasts 3. Animal cells have centrioles.
