Cell Challenge As a group, quietly discuss each question and agree upon one correct answer. The group with the most correct answers will win extra credit.

1) Who first observed cells when he examined cork underneath an early microscope?

2) Which organisms are the only living prokaryotes?

3) Name two functions of the lysosome.

4) What usually determines the shape of a cell?

5) Who was one of the first people to describe LIVING cells?

6) Which organelle transports ribosomes/proteins (before going to the Golgi body)?

7) Name two organelles that plant cells have and animal cells don’t.

8) Identify this organelle.

9) Identify this organelle.

10) Besides the chloroplast, which other organelle is thought to have evolved according to the theory of endosymbiosis?

11) What are cells called that have a nucleus?

12) Identify these organelles (green spheres).

13) a.Identify this organelle. b. What is the function?

15) Name the sac, proteins are placed within by the Golgi Body before being shipped away.

16)Which organelle is created by the nucleolus?

17) Which organelle stores water and waste within cells?

19) Which organelle produces the molecule ATP (energy) that is required by all cells?

20) Place the steps of protein creation in the order from start to finish. Step A Ribosomes attach and travel along the rough ER Step B Nucleolus creates the ribosome Step C Protein created by the ribosome is passed to the Golgi body Step D Vesicle protects the protein and releases it from the cell Step E Ribosomes exit the nucleus
