All of the other answer choices

11. Question 8
Storing and transmitting genetic material is the function of which biomolecule?
Lipids

Proteins
Nucleic Acids

12. Question 9
Selectively permeable membranes are important in cell function. What makes a membrane selectively permeable?
The ability to remove bacteria from the cell
The ability to use energy to make proteins used in the cell
The ability to modify, sort, and package proteins and lipids for storage or transport out of the cell
The ability to allow needed materials to enter and wastes to exit as well as the ability to block unneeded materials from entering the cell

13. Question 10
Which of the following statements is not part of the Cell Theory?
All living things are made up of cells
Cells are the basic units of structure and function in living things
All things are made up of cells
New cells are produced from existing cells

14. Question 11
What is the general name for all of the specialized substructures in cells that help carry out the essential functions of life?

15. Question 12
The __________ is a network of fibrous proteins that helps the cell with maintaining shape, support, and movement.
Cytoplasm
Cell membrane
Cytoskeleton
Cell wall

16. Question 13
Which organelle acts like a “post office” by modifying, collecting, packaging, and distributing proteins and other materials?
Vesicles
Golgi apparatus
Vacuole
Endoplasmic Reticulum

17. Question 14
What do we call a structure in the nucleus of a cell consisting essentially of one long thread of DNA that is tightly coiled?

18. Question 15
What is cytoplasm?

19. Bonus
Name an organelle that a plant cell has that animals cells do not.

20. Review Cell Packet

21. Enzymes Review

22. Proteins
Cellular processes are carried out by molecules. Proteins carry out most of the work of cells to perform the essential functions of life. One of the major functions of the cell is the production of proteins. The genetic information in DNA provides instructions for assembling protein molecules. In eukaryotic cells the nucleus, ribosomes, endoplasmic reticulum, vesicles, and the Golgi apparatus interact to produce, modify and transport proteins.

24. Plant Cells

25. Organelles
Chloroplasts capture energy from sunlight and convert it into food that contains chemical energy in a process called photosynthesis
Contain the green
pigment chlorophyll

26. Organelles
Cell wall: a strong supporting later around the cell membrane

27. Organelles
Central Vacuole filled with liquid; the pressure of the CV in these cells increases their rigidity (making it possible for plants to support heavy structures such as leaves and flowers)
