1 PLANT Labs summary questions (30 pts) 1. SEEDS--Without this part of the seed, the embryo has no food to grow before photosynthesis. a. seed coat b. embryo c. leaves d. cotyledon e. tap root 2. SEEDS--Which part of the plant germinates into the roots, stems, and leaves? a. cotyledon b. embryo c. seed coat d. food supply **Careful This question randomizes the lettered answers when on Schoology** 3. SEEDS (4pts)--Match the letter with the correct term for the seed: 1. A A. Seed Coat 2. B 3. C 4. D B. Leaves C. Cotyledon D. Xylem E. Embryo F. Root Hairs 4. SEEDS--Which step made it possible to dissect the seed easily? a. Soaking the seed in water to soften the seed coat. b. Using the tweezers to pull the embryo away from the cotyledon. c. Using the scalpel to cut through the tough outer covering of the seed. d. By cutting the seed in half. 5. SEEDS--Seeds are specialized depending on the type of plant because... a. It looks cooler. b. The seeds have adapted to be able to survive in the environment where the plant grows. c. Plants cannot have the same seeds because humans would be confused for planting and growing of our food. d. Seeds produce the plants. e. Seeds are not specialized to grow in different environments. 6. ROOTS--What is NOT a root function in plants? a. to absorb water b. to store food c. to anchor plants d. to produce food

2 7. ROOTS--What root system is represented by the rice plant? a. Tap root b. Cotyledon c. Diffuse root d. Vascular root 8. ROOTS--What part of the root is the protection for the rapid growth of the root? a. Diffuse root b. Tap root c. Root cap d. Xylem e. Phloem 9. 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

3 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.

4 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.
