1. Define what a cell is.

The smallest structural and functional unit of an organism, typically microscopic and consisting of cytoplasm and a nucleus enclosed in a membrane. Microscopic organisms typically consist of a single cell, which is either eukaryotic or prokaryotic.

2. What are the differences between a plant and animal cells.

Organelles in plant but not animal cells: 1. Chloroplasts 2. Cell walls

3. Use labeled diagrams or models to illustrate similarities and differences between plant and animal cell structures and describe their functions.

4. Describe the function of three of the following cells: muscle, nerve, bone, cartilage, secretory, epithelial, adipose, blood.

Bone- structure Muscle- movement Nerve- messages to/from brain

5. Explain the relationship between tissues that make up individual organs and the functions the organ performs (ex: valves in the heart control blood flow)

The valve between esophagus and stomach prevents esophageal regurgitation (stomach acid going up into esophagus)

6. Describe the components and functions of the digestive, circulatory, and respiratory systems in humans and how these systems interact.

Digestive system provides nutrients to circulatory system when it digests food, respiratory system (mainly lungs) provides oxygen to circulatory system, which circulates blood.

7. Find a picture that shows the three systems mentioned in #6. One picture for EACH system. 3 pictures total.

8. Find a picture of a LABELED Paramecium, include it in your #Tackk, describe your observations about it and how it compares to other organisms and how they function/survive.

Unlike many multicellular organisms, a paramecium is unicellular meaning it has only one cell. However, it has two nucleuses.
