Science Class

Today in class, we had to retake our quiz on the organelles of animal and plant cells.

After that, we were told to write three paragraphs in our notebooks each answering a question that was on the board.

• The first question was: "What are the similarities and differences between bacteria, animal, and plant cells?"
• The second question was: "If I say I am looking at a prokaryotic cell, what does that mean?"
• The third question was: "What came first, prokaryotic cells, or eukaryotic cells?"

For the first question, we said that the plant and bacteria cells had cell walls and the animal cells didn't. We explained that bacteria cells can survive on its own. We also said that animal and plant cells have organelles and bacteria cells doesn't (like...nucleus', endoplasmic reticulums, mitochondrias, golgi apparatus', etc.). In addition, bacteria cells have hair and most animal and plant cells don't (multicellular). The reading told us that these classifications would be that plant and animal cells are eukaryotic cells and bacteria cells are prokaryotic cells.

For the second we said that it means to look at a cell with no membrane-bound organelles. Such as bacteria cells.

Lastly, for the third question we said that prokaryotic cells came first because it was the first basic cell. It later evolved into eukaryotic cells. Like bacteria cells came way before humans and plants.

After we finished writing the three paragraphs, we discussed it by looking at a picture of bacteria, animal, and plant cells. That was the science class in Mr. Finley's 7th period class.

• Prokaryotic Cell: A cell that doesn't have any membrane-bound organelles within it (like mitochodria).
• Eukaryotic Cell: A cell that does have organelles within it.
