ROOTS (3pts)--Put the steps for germinating a plant in order: **Careful This question randomizes the numbered answers when on Schoology** a. Once the cotyledon is used up the green leaves begin to make food by photosynthesis. b. The embryo sprouts a root system. c. Water, fire, or some other source breaks the seed coat open. d. The embryo begins to use energy to begin germination. e. After growing roots, the embryo germinates a stem 10. ROOTS--Which type of root system did the beans grow? a. Tap root b. Diffuse root c. Root cap d. Xylem 11. STEMS--Xylem and phloem belong to the tissue system. a. root b. seed c. reproductive d. vascular 12. STEMS--Which tissue in a plant transports water from the roots up to the leaves? a. Xylem b. Phloem c. Veins d. Leaves e. Stomata
13. STEMS--Select the incorrect statement from the following: a. Phloem is made of living cells. b. Xylem carries water and minerals upwards from the roots. c. Phloem transports water and minerals from the roots to the leaves. d. Phloem carries food from the leaves to the rest of the plant. e. Xylem is made up of cells. 14. STEMS--A stick of celery is left in a beaker containing a solution of blue food coloring. After two days, the celery is taken out and it is seen that parts of the celery have turned blue. What is the name given to the blue part of the plant? a. phloem b. xylem c. cotyledon d. stomata e. stalk 15. STEMS--The vascular bundles in plants act like human. a. skeleton b. skin and hair c. heart and lungs d. veins and arteries 16. LEAVES--The leaf's main job is to... a. protect the stem of the plant. b. provide energy to the plant. c. help the plant reproduce by attracting pollinators. d. provide support to the plant in high winds by diffusing the wind. 17. LEAVES--The stomata are similar to what part of a human body? a. the human mouth which allows gases to flow in and out. b. the human heart which pumps fluids throughout the organism. c. d. the human bones because it provides support helping to maintain the upright posture. d. the human blood since it provides nutrients to the rest of the organism 18. LEAVES--In our experiment, we found more stomata on the bottom of the leaf than the top. This represents which of the following characteristics of living things? a. the ability to respond since stomata can move from the top to the bottom of a leaf when they want. b. the ability to reproduce since the location of the stomata helps with plant reproduction. c. the ability to grow and develop since stomata are responsible for photosynthesis. d. the ability to adapt since the location of the stomata provided an advantage allowing plants to survive through warmer climates.
19. LEAVES--In the fall, leaves begin to change color. Which of the following best explains why leaves begin to change color? a. The stomata are starting to shut down which prevents photosynthesis from occurring. b. There's not as much sunlight which means the tree doesn't have as much energy to make chloroplasts. c. The xylem and phloem begin to freeze since it s colder which prevents water and sugar from moving through the plant. d. The plant is using all of its energy to reproduce so there is not enough sugar to maintain the green color. 20. FLOWERS--Which does a flower produce in greater numbers: ovules or pollen grains? Why? a. ovules because it allows a plant to create more seeds. b. ovules because it will allow a plant to accept more pollen grains. c. pollen grains because it will allow for a greater chance at reproducing. d. pollen grains because there are more flowers available for reproduction than there are pollen grains. 21. FLOWERS (2pts)--What are some adaptations of flower petals to help attract pollinators? (select all that apply) a. petals provide an aroma to attract pollinators to help move pollen grains. b. petals are shaped like a cup to hold water so the flower can obtain and use energy. c. petals are made to provide photosynthesis to the reproductive parts of a plant. d. petals are a certain color to attract pollinators to help with reproduction. 22. FLOWERS--How is the stigma of a flower adapted to capture and hold pollen? a. It's sweet smelling which will allow it to capture and hold pollen. b. It's sticky which allows it to capture and hold pollen. c. It's shaped like a hand which will allow it to capture and hold pollen. d. It's green which will allow it to make its own energy for reproduction. 23. FLOWERS--Explain the differences between pollination and fertilization. a. Pollination occurs when pollen sticks to a bird while fertilization only happens in animals. b. Pollination happens when pollen reaches the ovary while fertilization happens when a seed forms. c. Pollination happens when pollen sticks to the stigma while fertilization happens when pollen meets the ovum. d. Pollination happens only in gymnosperm plants while fertilization happens in both gymnosperm and angiosperm plants. 24. FLOWERS--Why are the pollen grains on the anther far enough away from the stigma but also close enough to go in? a. to encourage pollinators to come to the plant. b. to improve the smell of the flowers which will attract more pollinators. c. to increase the flower's chance to reproduce. d. to help prevent the plant from fertilizing itself.
