Unit 3

Across

2. Strong supporting layer around the cell membrane in some cells.
5. Process used by plants and other autotrophs to capture light energy and use it to power chemical reactions and convert carbon dioxide and water into oxygen and energy rich carbohydrates such as sugars and starches.
7. Set of reactions in photosynthesis that use energy from light to produce ATP and NADPH.
8. Cell organelle that stores materials such as water,salts,proteins, and carbohydrates.
9. principal pigment of plants and other photosynthetic organisms.
10. in cells structure that contains the cell’s genetic material in the form of DNA.
11. Organism that obtains food by consuming other living things, also called a consumer.
14. the amount of energy needed to raise the temperature of 1 gram of water by 1 degree celsius.
16. first and longest phase of Mitosis in which the genetic material inside the nucleus condenses and the chromosomes become visible.
17. A Fundamental concept of biology.
18. organism whose cells contain a nucleus.
21. Cell Organelle consisting of RNA and protein found throughout the cytoplasm in a cell, the site of protein synthesis.
22. Compound used by cells to store and release energy.
23. Organism that is able to capture energy from sunlight or chemicals and use it to produce its own food from inorganic compounds also called a producer.
24. Specialized structure that performs important cellular functions within a eukaryotic cell.
25. light absorbing molecules used by plants to gather the suns energy.
26. organelle in cells that modifies, sorts, and packages proteins and other materials from the endoplasmic reticulum for storage in the cell or release outside the cell.
28. cell organelle that converts the chemical energy stored in food into compounds that are more convenient for the cell to use.
29. Network of protein filaments in a eukaryotic cell that gives the cell its shape and internal organization and is involved in movement.
31. Fluid portion of the chloroplast, outside of the thylakoids.
32. Thin, flexible barrier that surrounds all cells, regulates what enters and leaves the cell.
33. Saclike photosynthetic membranes found in chloroplasts.
34. Flexible double-layered sheet that makes up the cell membrane and forms a barrier between the cell and its surroundings.
35. Phase of mitosis in which the chromosomes line up across the center of the cell.

Down

1. Property of biological membranes that allow some substances to pass across it while others cannot, also called semi permeable membrane.
2. Structure in an animal cell that helps to organize cell division.
3. Process that does not require oxygen.
4. carrier molecule that transfers high energy electrons from chlorophyll to other molecules.
6. process that requires oxygen.
7. Set of reactions in photosynthesis that do not requrie light, energy from ATP and NADPH is used to build high energy compounds such as sugar also called the Calvin Cycle.
9. organelle found in cells of plants and some other organisms thatt captures the energy from sunlight and converts it into chemical energy.
12. Cell organelle that breaks down lipids, carbohydrates and proteins into small molecules that can used by the rest of the cell.
13. Unicellular organism that lacks a nucleus.
15. Fluid portion of the cell outside the nucleus.
17. threadlike structure within the nucleus that contains genetic information that is passed on from one generation the the next.
19. Process that releases energy from food in the presence of oxygen.
20. internal membrane system found in eukaryotic cells, place where lipid components of the cell membrane are assembled.
27. Part of eukaryotic cell division during which the cell nucleus divides.
30. Cycle Series of events in which a cell grows, prepares for division and divides to form two daughter cells.
