List 3 similarities between prokaryotic & eukaryotic cells

CELLS: ORGANELLES

OBJECTIVES1. Define the term organelle.2. List organelles found in

living cells3. Identify the important roles

organelles play within a cell.

4. Compare and contrast animal and plant cells.

5. Label organelles in plant and animal cells.

ORGANELLES = organized or specialized structures within a living cell

= differentiated structure within a cell

= parts of the cell that act like specialized “organs”

1.CYTOPLASM Description: fluid like substance that fills the area of the cell outside the nucleus

Function: site of many cellular activities; surrounds organelles

2.NUCLEUS Description: large organelle near the center of the cell, composed on DNA & proteins

2.NUCLEUS Function: control center of the cell (acts like a brain)Chromatin = coiled up DNA in nucleus

Nuclear Envelope = surrounds nucleus

AVID THINKING STRATEGY: TATTOO OR BODY ART You are in charge of developing a tattoo

to allow the world to know about one of the discussed organelles.

1. The centerpiece of the tattoo must be a slogan representing the organelle.

2. The surrounding artwork (minimum of 3 colors) must represent the organelle’s function

3. The artwork must be suitable for all ages and appropriate for viewing in all social situations.

4. 5-7 complete sentence explanation of how the artwork represents the organelle AND the best location for the tattoo on the body

THINKING STRATEGY #21: DIAMANTE POEM This poem follows a very specific pattern.

There are 7 lines that will make the shape of a diamond.

Draw the following diamond on the next blank page in your notebook.

THINKING STRATEGY #21: DIAMANTE POEM This poem follows a very specific pattern.

There are 7 lines that will make the shape of a diamond. Line 1: topic (noun 1) Line 2: 2 describing words for noun 1

(adjectives) Line 3: Three action words (“-ing”) for noun 1 Line 4: 4 words. 2 words about the topic & 2

words opposite to those in line 2. Line 5: 3 action words for the ending noun 2. Line 6: 2 words to describe noun 2. Line 7: Ending noun 2. (opposite of line 1)
