Plant Structure and Function Classwork 1. What are flowering plants called? 2. Describe how the cotyledons of monocots and dicots differ. 3. Describe how the flower petal arrangements of monocots and dicots differ. Homework 4. Identify the two main groups of angiosperms. 5. Branched leaf veins can be found in what type of angiosperm? 6. Vascular bundles in complex arrangement are found in what type of angiosperm? 7. What type of angiosperm has one taproot? Classwork 8. What are the three main things that plants need to survive and grow? 9. Identify the two main sections of a plant body. 10. Describe why the root structure of a plant is important. 11. Where are terminal buds found? 12. Describe the function of terminal buds. 13. Where are axial buds found? 14. Describe what the hormone Auxin in the terminal bud does in a plant. 15. Provide examples of dicots with modified root systems. Homework 16. How are root hairs able to aid in absorption? 17. Describe the location of nodes and internodes. 18. Describe the function of axial buds. 19. Describe why pruning a bush or tree allows it to become bushier or to produce more fruit. 20. Why do turnips have modified root systems? 21. Define stolon and describe its importance. 22. Identify two examples of modified leaves and their significance. 23. Identify three organelles that are unique to plant cells and not found in animal cells. Classwork 24. Where are the reproductive organs of an angiosperm located? 25. Which reproductive organ is referred to as the “male”? 26. Which reproductive organ is referred to as the “female”? 27. Where is pollen found? 28. What is produced during meiosis and mitosis in a seed plant? 29. Identify the name of the structure known as the female gametophyte. 30. How is pollen able to travel from one plant to another? 31. Describe the importance of double fertilization. Homework 32. Identify the function of the sepal. 33. Identify the function of flower petals. 34. Describe the structure of the carpel. 35. What forms the first cell of the next sporophyte generation? 36. Identify the male gametophyte. 37. Where does the female gametophyte generate? Classwork 38. Describe the function of a fruit. 39. List the steps of pod formation. 40. Identify one main difference between monocot and dicot seed germination. 41. Define vegetative propagation. 42. Describe a disadvantage of genetically modified plants. Homework 43. What causes the hardening of the seed coat? 44. Describe an adaptation that plants have that allows them to grow during prime seasons. 45. Describe how a pineapple differs from a peach. 46. What happens to the cotyledons of both monocots and dicots? 47. Give an example of a plant that undergoes asexual fragmentation. 48. What advantage do fragmented offspring have over seeds? Plant Structure & Function Answers 1. Angiosperms 2. Monocots have one cotyledon and dicots have two 3. Monocots have petals in multiples of 3 and dicots have petals in multiples of 4 or 5 4. Moncots and Dicots 5. Dicots 6. Monocot 7. Dicot 8. Water, carbon dioxide, and sunlight 9. Roots and shoots 10. The roots are responsible for anchoring the plant in the soil, absorbing and transporting minerals and water for the plant, and storing food for the plant. 11. At the top of the plant 12. The terminal buds are where the plant grows in height. 13. Axial buds are found on the stem of the plant where the leaves attach to the stem. 14. It inhibits growth in the lateral or axial buds. 15. Carrots, beets, turnips, and potatoes 16. They increase the surface area of the roots allowing for a larger area to absorb water. 17. Nodes are where the leaves, flowers, and other stems attach to the main stem of the plant. The space between nodes is known as internodes. 18. Axial buds are where the plant is able to grow in width. 19. Removing the terminal bud removes the Auxin from the terminal bud, which then stops the inhibition of growth from the axial buds. 20. For the storage of carbohydrates. 21. A stolon is a modified stem that provides a means for asexual reproduction. 22. Spines such as those on a cactus allow for protecting. Tendrils allow a plant to grasp as they grow. 23. Central vacuole, chloroplast, cell wall 24. In the flower 25. Stamen 26. Carpels 27. Pollen is found on the anther of the stamen. 28. Diploid spores are produced during meiosis and haploid gametes are produced during mitosis 29. Embryo Sac 30. Pollen is transported by animals or by the wind. 31. In double fertilization one sperm fertilizes the egg forming the zygote and the other sperm is used in the formation of an endosperm, which is utilized to nourish the embryo. 32. The sepal is where the pollen is produced. 33. The flower petals attract pollinators. 34. The carpel consists of the stigma, the style, and the ovary. It is known as the female reproductive organ of the plant. 35. The zygote. 36. Pollen 37. In the ovule 38. Protect the seeds 39. Pollination, petals drop and ovaries start to grow, ovaries form the pod. 40. The shoots of dicots develop into hooks and the shoots of monocots do not. 41. It is the production of offspring from a single parent; asexual reproduction. 42. They contain little genetic diversity and are therefore easily wiped out by disease. 43. The loss of water from the seed. 44. Seed dormancy allows the plants to stop their maturation at a certain point and start again when conditions are right. One way this can be controlled is through hormones. 45. A pineapple is an example of a multiple fruit made from many united flowers, whereas a peach is a simple fruit made from one flower. 46. They decompose in the soil. 47. Garlic 48. They are better suited for their immediate environment.
