7th Grade Science, Unit 1 - Cells

Standard: 7.L.1.1. Students are able to identify basic cell organelles and their functions.
Objective: I can identify the parts of a microscope.
1. Label the parts on the diagram of the microscope below.

(Teacher white out parts students should know.)
Proficient Student Response:
Objective: I can operate a microscope to view small objects.
1. Checklist
____ Student carries microscope properly by the base and arm.
____ Student correctly mounts slide.
____ Student correctly places slide on stage.
____ Student focuses microscope using both fine and coarse focus.
____ Student draws accurate representation of object observed under the microscope.
Proficiency reached when student can complete the checklist.
Objective: I can use a microscope to identify main parts of the cell.
1. Teacher prepares a station with a cheek cell and onion cell under the microscope. Students observe both cells and draw a diagram of their observations. Students label all cell parts that are observable.
Proficient student response:
Onion cells:

Cheek cells:

Objective: I can identify the main organelles in the cytoplasm.
1. Label the parts of the animal cell.

(Use proficient student response diagram. White out parts they need to know.)
Proficient student response:

Objective: I can describe the function of the nucleus.
1. Why is the nucleus important in the cell? (Short answer)

Proficient student response:

The nucleus is the control center of the cell. It tells the cell what to do (what type of cell to become, tells the organelles in the cell what to do).

Objective: I can describe the function of basic cell organelles.
1. Match the name of the cell organelle with its function
_____ mitochondria
_____ vacuoles
_____ lysosome
_____ chloroplasts
_____ endoplasmic reticulum
_____ ribosomes
_____ Golgi bodies

Proficient student response:
_____ mitochondria B
_____ vacuoles E
_____ lysosome D
_____ chloroplasts C
_____ endoplasmic reticulum F
_____ ribosomes A
_____ Golgi bodies G

Objective: I can explain how materials move into and out of the cell through the cell membrane.

1.  Materials move in and out of the cell in two ways. ______requires energy to move materials, and ______does not require energy to move materials across the cell membrane.

A.  diffusion, active transport

B.  active transport, passive transport

C.  passive transport, active transport

D.  passive transport, diffusion

Proficient student response:

B

Objective: I can explain why cell walls are important in plant cells.

1.  Explain a reason why cell walls are important to plants.

Proficient student response:

Cell walls are important to provide protection for the cell and to give the plant support to stand up straight.
