Unit 1 Review

Unit Target: Explain how the structure of living things is related

to their function.

State the safety rules. (knowledge)

Broken glass should be

a.placed in the garbage can

b.pushed into the sink

c.swept into the broken glass bucket

d.left for the teacher to clean up

c. swept into the broken glass bucket.

Which of the following is not true?a.Report all accidents or injuries to the teacher.b.Wear safety goggles when mixing chemicals.c.Clean up spilt chemicals with paper towels.d.Keep flammable materials away from open

flames.c. Clean up spilt chemicals with paper towels.

What is the safest way to dress for lab?

a.Long pants, closed shoes, long hair tied back

b.Shorts, sandals and a loose T-shirt

a.

Given a situation determine the proper safety and first aid procedures. (reasoning)

True or false? Correct if false.

If your lab partner cuts their finger, have them wash it off in the eye wash station.

False. Sink

If your clothes catch on fire, panic!

False. Stop, Drop and Roll

If someone faints, give them fresh air.

True

• The trunk of a tree is the same shape as the columns found on many buildings. What is the function of the columns? How does this relate to trees?

• The function of the columns is to support the weight of the roof of the building just as the trunk of a tree supports the branches and leaves. A cylinder shaped structure is a strong structure.

DLT: Determine how the structure of an object determines its function (R)

Learning Target: Define cell (knowledge)

A(n) ______________ is the basic unit of all living things that can carry out all the functions of a living thing.

a. atomb. organc. macromoleculed. cell

Answer: d

Learning Target: State the cell theory (knowledge)

Which of the following is a component of the cell theory?

a. all living things are made of cellsb. atoms are the basic unit of structure and

function in an organismc. new cells are produced from existing

atomsd. cells can move

Answer: a

Does the cell theory apply to all living things?

yes

Learning Target: Compare and contrast between prokaryotic cells and

eukaryotic cells. (reasoning)

• What type of cell is small and does not have a nucleus to hold the genetic material- prokaryotic or eukaryotic?

Prokaryotic cell

• What type of cell is larger in size, has complex structures and a nucleus to hold the genetic material- prokaryotic or eukaryotic?

• eukaryotic

Which cell is a prokaryotic cell?

Which of the following is not a characteristics shared with all cells?

a. Cell wall

b. Cell membrane

c. Genetic material

d. Cytoplasm

a. Cell wall

Which image shows plant cells?

How could you tell?The plant cell has a cell wall.

What organelle does a plant cell have that allows it to make food from the sun’s energy?a. Chloroplast

b. Mitochondria

c. Ribosomes

d. Golgi Apparatus

a.

Do animal cells have chloroplasts?

No

LearningTarget: Investigate how the structures of the cell relate to their specific functions. (reasoning)

mitochondria a. controls what goes in and out of Golgi apparatus the cellnucleus b. stores nutrients and watercell membrane c. control center of the cellgenetic material d. stores instructions for cell activitiesvacuole e. place where proteins are made ribosome k. produces energy for the cellcell wall l. produces and stores RNAlysosome m. a system of tubes that transports endoplasmic reticulum proteinsnucleolus n. uses enzymes to break down

macromoleculeso. modifies, sorts and packages proteinsp. support and protection for a plant cell

If a white blood cell rushed to the site of a cut to engulf dirt and invading germs what organelle would the blood cell then use to break down the dirt and germs?

Lysosome

If a plant cell takes in water through osmosis, what organelle will store the water?

Vacuole

Which cell would most likely have more mitochondria? The cells in your brain or the dead skin cells found on the surface of your body.

The cells in your brain because they need more energy. Dead cells don’t need any energy at all. They are dead!

Which organelle does the Golgi Apparatus work most closely with?

a.Nucleus

b.Smooth endoplasmic reticulum

c.Rough endoplasmic reticulum

d.Mitochondria

c. Rough ER- When a protein is made in the rough ER, it is transported to the Golgi apparatus in preparation for its release from the cell. (Remember the golgi apparatus is used to modify, sort, and package proteins for export.)

When you studied the function of organelles your author placed them into categories based on their similarities. (See page 207) Which of the following are most related in function?

a.Nucleus and cell membrane

b.Vacuoles and lysosomes

c.Ribosomes and chloroplasts

d.Mitochondria and centrioles

b. Both are structures that store and clean-up

• Why do cells have different structures?

• Cells must have different structures to carry out different functions. For example a plant cells job is to take sunlight and turn it into usable energy so a plant cell has structures called chloroplasts to help it carry out this function.

There will be a cell analogy on the test. You may want to review the cell analogy notes from class and complete the cell city analogy.

As you can see there are a lot of questions about the function of organelles so memorize the functions and then be ready to THINK on the test.

Check your Cell City Analogy

1. Mitochondria – hydraulic dam

2. Ribosomes – Small Shops

3. Nucleus – Town Hall

4. Endoplasmic Reticulum – special carts

5. Golgi Apparatus – postal office

6. Protein – widget

7. Cell membrane – fence

8. Lysosomes – scrap yard

9. Nucleolus – carpenter’s union

Identify the parts of the microscope and explain how each part functions. (knowledge)
