SC.912.L.14.3 Compare and contrast the general structures of plant and animal cells. Compare and contrast the general structures of prokaryotic and eukaryotic cells. 

WARM UP Prokaryotic and eukaryotic cells have important similarities and differences. Which of the following is a major difference between prokaryotic and eukaryotic cells? A. Eukaryotic are enclosed by membranes while prokaryotic cells are not. B. Prokaryotic cells use DNA while eukaryotic cells do not. C. Eukaryotic have a nucleus while prokaryotic cells do not. D. Prokaryotic cells are filled with cytoplasm while eukaryotic cells are not.

Interactive Journal Left Side Right Side Fill in the chart with the organelles (and their functions) found in prokaryotic, eukaryotic, or both types of cells. Answer the questions below and develop a mnemonic device for the organelles found in both types of cells. The right hand side notes should be printed and given to the students in order for them to properly secure it into their journal. Students will fill out the right side interactive notes as the instructor goes through the notes. At the conclusion of the notes move to the “WE DO” and have the students complete the left hand side chart and answer the questions below. You may need to define, explain, or give an example of a mnemonic device.

Cells There are two categories of cells called prokaryotic and eukaryotic. Despite the many differences between cells, all cells have a cell membrane, cytoplasm, and DNA.

Prokaryotes – The first cells They do not have a membrane-bound nucleus. They have a single, circular chromosome (1) and plasmid DNA (2).

Prokaryotic Cells Prokaryotic cells are structurally simpler than eukaryotic cells. They are small and lack complex organelles. Common example - bacteria

Eukaryotic Cells These cells are distinguished by the presence of a nucleus. The two main types of eukaryotic cells are - ANIMAL PLANT

Eukaryotic Cells Eukaryotic cells are partitioned into functional compartments called organelles for better efficiency. Higher forms of life are composed of more complex, larger eukaryotic cells These cells include protists, fungi, plants, and animals.

Re-Try Prokaryotic and eukaryotic cells have important similarities and differences. Which of the following is a major difference between prokaryotic and eukaryotic cells? a. Eukaryotic are enclosed by membranes while prokaryotic cells are not. b. Prokaryotic cells use DNA while eukaryotic cells do not. c. Eukaryotic have a nucleus while prokaryotic cells do not. d. Prokaryotic cells are filled with cytoplasm while eukaryotic cells are not. Have students re-answer the warm up question. Circulate the room and observe students as they record their answer. Address misconceptions afterwards. At this point all students should understand why C is the correct answer.

We Do Complete the provided chart on a left hand page. Answer the questions below the chart and develop a mnemonic device to remember the organelles that are found in both types of cells.

You Do – Exit Slip Questions The following questions can be projected when an instructor reaches the “You Do” or an instructor can use the handout.

You Do Questions 1. While looking at an unknown cell under the microscope, which of the following organelles would NOT help you determine if you were looking at a eukaryotic cell or a prokaryotic cell? a. Cell Wall b. Central Vacuole c. Mitochondria d. Plasma Membrane

You Do Questions 2. Prokaryotic cells and eukaryotic cells vary in structure. Which statement explains the presence or absence of internal membranes in one of these types of cells? a. Eukaryotic cells require internal membranes for active transport. b. Prokaryotic cells require internal membranes for cellular reproduction. c. Prokaryotic cells have internal membranes that surround cellular organelles for protection. d. Eukaryotic cells have internal membranes that surround cellular organelles to increase functional efficiency. Correct answer is D.

You Do Questions 3. Which of the following organelles are found in both prokaryotic and eukaryotic cells? a. DNA, plasma membrane, ribosomes b. DNA, mitochondria, plasma membrane c. DNA, nucleus, mitochondria d. DNA, plasma membrane, nucleus
