Cell Test Review Part 1

​Organization of Organisms

Organisms are living things.

​

They are organized from the simplest to most complex levels in this way:

​

cells, tissues, organs, organ systems, and organisms​

Multiple Choice

Based on this diagram, what letter represents organs?

• X

• Y

​The cells we have learned about are prokaryotes and eukaryotes cells. Also, plant and animal cells.

​TISSUES

​Some examples of organs are skin, liver, heart, brain and the stomach.

​​ORGANS

​

​Examples of organisms include unicelluar and multicellular. Bacteria is unicellular. Humans are multicellular.

1. All organisms are made up of ​cells

2. Cells are the basic unit of life

3. All cells come from preexisting cells.​

​Cell Theory

​

Multiple Choice

Which is a true statement based on the cell theory?

• amoebas must come from amoebas

• flies come from meat

• frogs come from mud

• virus are alive, even though they do not have a cell

​Cell Theory Scientists

​Robert Hooke

Coined the word "cell"

​

Looked at cork under the microscope​

Some text here about the topic of discussion

Discovered microbes, like bacteria, after making a better microscope.

​

Looked at pond water and teeth scrapings.​

​Connective tissue: strong, like bones and tendons

Epithelial tissue: protective layers, like the skin

Muscle tissue: skeletal, smooth, and cardiac

Nervous tissue: makes up the brain and spinal cord​
