  2. Why do plants need to do both photosynthesis and cellular respiration?

  3. Plants must do photosynthesis to make their food (glucose). They must then also do cellular respiration to withdraw the energy out of the glucose.

  4. How are the materials and products of photosynthesis and cellular respiration related?

  5. They are opposite. The products of photosynthesis are the materials of cellular respiration and the products of cellular respiration are the materials of photosynthesis. For example the products of photosynthesis are C6H12O6 and 6O2. This is exactly the same as the materials needed for cellular respiration.

  6. Where is chlorophyll found in a plant cell? What is chlorophyll’s function?

  7. Chlorophyll is a green pigment found inside the chloroplasts. The function of the chlorophyll is to capture the energy from the sun. The plant uses this energy to perform photosynthesis.

  8. Photosynthesis is the process that allows plants to make their own food, therefore they are called __________________?

  9. Autotrophs

  10. Explain two reasons why plants being able to undergo photosynthesis help us.

  11. Answers will vary. Possible answers are: 1) Without photosynthesis we would have too much carbon dioxide and not enough oxygen. 2) Without photosynthesis plants would not be able to grow and survive and therefore would not be able to provide us with food, medicine and products. 3) Without photosynthesis plants would not be able to grow and survive and we would not be able to enjoy the beauty they give to us.

  12. If the eyepiece of the microscope is 10x and the medium power objective is 10x, what is the total magnification?

  13. 10 x 10= 100x total magnification

  14. True/False. If false-write a sentence or two explaining why. You should always use the coarse objective knob when focusing on high power.

  15. False. The statement is false because you should never use the coarse adjustment knob when you are focusing on high power. You should only use the fine adjustment knob.

  16. Explain the difference between pollination and fertilization.

  17. Pollination is moving the pollen from one part of the flower to another (in the case of a perfect flower) or moving the pollen from one flower to another flower. Fertilization is when the pollen (male sex cell) joins with the egg (female sex cell) and the seed is created. This occurs in the ovary.

  18. What is letter A pointing to? What is its job? What is letter B pointing to? What is its job? A B

  19. A is pointing to the nosepiece. The nosepiece holds the objective lenses and you turn it to change the level of magnification. B is pointing to the fine objective knob. It raises and lowers the stage a tiny amount and you use this to “fine tune” your image.

  20. Explain 3 ways seeds can be dispersed.

  21. Animals can move seeds to another location because seeds stick on their fur. Animals can eat seeds and excrete the seeds in their feces. This helps move them to a new location. Wind can move seeds to a different location. Water can carry seeds to new location.

  22. What is the function of the anther and why is it so important in plant reproduction?

  23. The anther produces pollen (the plant’s male sex cell). Without the anther there would be no pollen to fertilize the eggs and the plant could not produce seeds. Without seeds the plant would not be able to reproduce.

  24. After the eggs are fertilized by pollen the ovary swells and becomes a ___________.

  25. Fruit

  26. What is the letter D pointing to? What are its TWO functions?

  27. Sepals The sepals protect the developing bud as it grows and matures. They are green so they produce food by photosynthesis.

  28. What two letters make up the male part of the flower? What are the parts called and what are their functions? What is the entire male part named?

  29. -The two letters that make up the male part are B and H. -B is called the Anther and it produces pollen and H is called the Filament, it holds the anther up high so its pollen can be taken from one plant to another. -The entire male part iscalled the Stamen.

  30. What is the female part of the flower called? What three parts make up the female part? What are all three of their functions ?

  31. The female part is called the pistil. It is made up of the stigma (sticky and catches the pollen), the style (holds up the sigma so it’s in a good position to catch pollen) and the ovary (holds the eggs and serves as a place for seeds to grow).

  32. What is an atom?

  33. The smallest amount of any pure substance. Atoms can not be broken down into smaller pieces and still be identified as what element they are.

  34. What is an element? Give three examples.

  35. An element is a pure material. The atoms of an element are identical to each other. Three examples are Carbon, Oxygen and Hydrogen. (answers will vary)

  36. What does the 12 mean in C6H12O6? In the below equation, how many molecules of C6H12O6 are there? 6CO2 + 6H2O C6H12O6 + 6O2

  37. The 12 means that there are 12 atoms of Hydrogen in one molecule of glucose. In the equation, there is one molecule of glucose.

  38. Is a molecule always a compound? Explain.

  39. No. In order to be a compound the molecule must be made up of at least 2 different types of atoms, or at least two elements. O2 isnot a compound molecule. H2O is a compound because made of oxygen and hydrogen.

  40. What are the equations for photosynthesis and cellular respiration?

  41. Photosynthesis 6CO2+6H2O  C6H12O6+6O2 Light Cellular Respiration C6H12O6+6O26CO2+6H2O + energy

  42. Name the outer surface of a plant’s skin.

  43. Epidermis

  44. Explain why plants want their seeds to be spread out.

  45. Plants want their seeds to be spread out because they don’t want to compete for resources such as sunlight, water, nutrients in the soil and space to grow.

  46. How does CO2 enter the plant? Where are these found?

  47. CO2 enters the plant and O2 exits the plant through the stomata. They are found on the backside of the plant’s leaves.

  48. It requires a lot of energy for a plant to produce a fruit. Explain why a plant would spend this large amount of energy.

  49. Producing fruit ensures that a plant will be successful in reproducing. The fruit is eaten by animals and the animals help disperse the seeds away from the parent plant. This makes sure the plants do not compete with each other for space and sunlight.

  50. What does the word “Eukaryotic” mean and how does it relate to plants?
