  1. Review for Unit 4 test You can do it!!!!

  2. Without gas exchange, a plant would be unable to • make food • make minerals • absorb sunlight • absorb water from the soil.

  3. Xylem and phloem are NOT • transport subsystems • present in bryophytes • vascular tissues • present in ferns.

  4. Which of the following is NOT a characteristic of all plants? • are eukaryotic • produce seeds • have cell walls • are multicellular

  5. Plants use the energy of sunlight to • exchange gases with the atmosphere • carry out cellular respiration • take in water from the soil • carry out photosynthesis.

  6. Which of the following includes all the others? • Xylem • Phloem • vascular tissue • tracheids

  7. Which term below is LEAST closely related to the others? • Fruit • Ovary • seed • cone

  8. Which of the following includes a plant embryo, a food supply, and a protective covering? • pollen grain • Seed • Spore • gametophyte

  9. Living on land required that plants • evolve photosynthetic pigments • conserve water • exchange gases • have cell walls.

  10. If some of the xylem of a young oak tree was destroyed, it would most likely interfere with the tree’s ability to • conduct sugars to the roots • absorb carbon dioxide from the air • absorb sunlight • conduct water to the leaves.

  11. A monocot is an angiosperm that has • a taproot • one seed leaf • branched veins • two seed leaves.

  12. Ground tissue is found in plant • stems only • roots and stems only • stems and leaves only • roots, stems, and leaves.

  13. Angiosperms produce seeds inside protective structures called • pollen grains • Ovaries • Cones • petals.

  14. Root pressure • causes a plant’s roots to absorb water. • forces the water in xylem downward. • is produced in the cortex of the root. • is produced in the vascular cylinder by active transport.

  15. Which of the following should a student examine under a compound microscope to observe cell division? • epidermis of a leaf • xylem from a tree trunk • tip of a shoot • phloem from the leaf of a plant

  16. The vascular cylinder of a root consists of • xylem only. • phloem only. • xylem and phloem. • xylem, phloem, and ground tissue.

  17. Which of the following is the only tissue that produces new plant cells? • meristematic tissue • ground tissue • phloemd • xylem

  18. Most of the photosynthetic activity in plants takes place in the • mesophyll. • guard cells. • stomata. • xylem.

  19. Water will move higher in a narrow glass tube than in a wide glass tube because of • adhesion only. • pressure. • capillary action. • cohesion only.

  20. The stomata of leaves are usually open in • light if a plant has enough water. • light if a plant has too little water. • darkness if a plant has enough water. • darkness if a plant has too little water.

  21. Vascular tissue in plants consists of • meristem. • parenchyma and collenchyma cells. • xylem and phloem. • epidermal cells.

  22. A seed plant is anchored in the ground by its • stems. • leaves. • roots. • trichomes.

  23. Through which plant cells does water move by capillary action? • phloem cells • mesophyll cells • guard cells • xylem cells

  24. A carrot is a(an) • taproot. • monocot. • fibrous root. • extensive root system.

  25. Minerals from the soil move into roots by • diffusion. • active transport. • transpiration. • root pressure.

  26. One of the main functions of stems is to • carry out photosynthesis. • transport substances between roots and leaves. • store carbohydrates. • store water.

  27. The attraction of water molecules to other molecules is called • adhesion. • capillary action. • cohesion. • transpiration pull.

  28. The sterile leaves of a flower are the • carpel and stamens. • stigma and style. • filaments and anthers. • sepals and petals.

  29. A seed that is dispersed to an area far away from the parent plant might face less • Alternation • germination. • pollination. • competition.

  30. Seeds dispersed by animals typically are contained in • fleshy, nutritious fruits. • buoyant structures. • cones. • lightweight structures.

  31. Corn, sugar beets, cauliflower, and cabbage were all developed by • plant propagation. • pollination. • germination. • selective breeding.

  32. Pollen grains are produced by • male reproductive structures. • ovules. • female reproductive structures. • flowers.

  33. Most people in the world depend on food crops such as • sugar beets, cabbage, and broccoli. • strawberries, chilies, and avocadoes. • wheat, rice, and corn. • apples, grapes, and strawberries.

  34. A ripened ovary that contains seeds is called a(an) • embryo. • fruit. • ovule. • vegetable.

  35. The seed type shown in Figure 24-5 that is generally dispersed by animals is(are)

  36. The early growth stage of a plant embryo is called • fertilization. • germination. • dormancy. • pollination.

  37. Seeds that are dispersed by wind and water typically are • lightweight. • nutritious. • large. • sweet and fleshy.
