1.
True or False. The cells in your body are Eukaryotic. Explain.
A: True, humans are animals and all animal cells are eukaryotic (has a nucleus)
2. True or False. Prokaryotes are basic types of cells that include simple organisms like paramecia and yeast. Explain.
A: Prokaryotes are simple organisms but paramecia and yeast are examples of eukaryotic organisms.
3. What are the four different kingdoms that include eukaryotic cells?
A: Plant, Animal, Fungi, and Protist
4. If you wanted to see a cell wall, which object should you look at under a microscope- a cheek cell, a ladybug wing, or a grape leaf? Explain.
A: Grape leaf because cell walls are found in plant cells, not animal cells.
5. Explain why bacteria are great examples of simple single-celled organisms.
A: Bacteria are simple single-celled organisms because they are prokaryotic, which means they don’t contain a nucleus.
6. Explain the primary reason for why plant cells are generally so firm and crisp.
A: Plant cells attribute their crispness to something called turgor pressure. When a vacuole in a plant cell fills with water, pressure increases and the vacuole presses against the cell membrane and wall. This creates a firm and crisp cell.
7. True or False: An organism needs to have a nucleus in order to carry out the main functions of life.
A: False, bacteria are prokaryotic organisms and don’t contain a nucleus.
8. Arrange the following in order of least to most complex: organelles, systems, molecules, atoms.
A: Atoms, molecules, organelles, systems.
9. Does a sword fern contain more atoms, cells or ribosomes? Explain
A: Atoms, because atoms make up organelles such as ribosomes, and organelles make up cells.
10. Explain the educative purposes of the Ribbon of Life. What does the ribbon of life tell us?
A: The ribbon of life explains what materials make up more complex materials. It tells us the order of complexity for how life is organized.
11. Explain the statement: Every tissue contains cells, but a cell does not always make up a tissue.
A: Every tissue is composed of cells, but a cell might not make up a tissue if it is a single-celled organisms such as a paramecium.
12. Explain why tissues are more complex than organelles.
A: Tissues are more complex than organelles because organelles make up cells, and cells make up tissues.
13. Explain the role of the nucleus.
A: The control center of the cell. Contains the DNA of the organism
14. What is the main organelle responsible for the growth and development of a cell?
A: Ribosomes. These organelles help synthesize, create proteins that are used as building blocks within cells.

15. After you have digested sugar molecules, which organelle will use them, and for what reason?
A: Mitochondria take in the sugar molecules and help break them apart, releasing energy. The mitochondria are considered the power plants of the cell.
16. Which organelle is a major storehouse for water in a plant?
A: Vacuoles are large storehouses for water in a plant cell.
17. This cell structure controls what passes in and out of the cell.
A: Cell membranes are porous and allow various gasses, water, waster, food to pass into and out of the cell.
18. One way plant cells are different from animal cells is the presence of chloroplasts. Why does a plant contain these organelles, but not an animal?
A: Plants get their energy/food through photosynthesis. Photosynthesis takes place inside chloroplasts. Animals acquire their food by eating other organisms because they don’t contain chloroplasts.
19. Even though many organisms live on land, why is safe to say ‘all life is aquatic?’
A: All life is considered aquatic because cells are made up of mostly water. Essentially, life on land is only able to exist because it contains a great amount of water within its body.
20. Explain how a cell is able to exchange gasses.
A: A cell is able to exchange gasses through the porous cell membrane.
21. Which organelle is considered the ‘post office’ of the cell? Explain why?
A: The golgi is considered the ‘’post office of the cell. It is responsible for packaging up molecules such as protein, and shipping them to various locations.
22. Explain the primary difference between vacuoles in plant cells and vacuoles in animal cells?
A: Vacuoles in plant cells are much larger than vacuoles in animal cells. More importantly, vacuoles in plant cells are responsible for maintaining turgor pressure inside the plant cell.
23. How is the statement, “we are made up of chemicals” true?
A: Are body is made up of atomic matter, or in other words, various chemical elements. Even though we are organisms, we are still composed of atoms, just like a chair, apple, or a lightbulb.
24. These organelles are found in all cells.
A: Ribosomes, Cytosol, and a Cell Membrane are organelles that are found in all cells.
25. Why is glitter a great representation for model ribosomes?
A: Ribosomes number thousands inside a cell and they are very small.
