Biology OYO

Module 14 - OYO

QuestionAnswer
14.1 A gardener plants a group of flowers that grow beautifully over the course of a year. In order to have the same flowers each year, however, he must replant. Are these most likely woody plants or herbaceous plants? Herbaceous.
14.2 A carrot is the root of a carrot plant. What kind of organ is it? Vegetative organ.
14.3 A section of plant no longer has any mitosis going on. What kind of tissue should be absent in that section? Meristematic tissue.
14.4 Determine the shape, margin, and venation of the marked leaves on page 435. a. deltoid, serrate, pinnate b. lobed, entire, palmate c. cleft, dentate, palmate d. linear, entire, parallel
14.5 A leaf cannot get the carbon dioxide that it needs for photosynthesis. What, most likely, is wrong? The stomata are not opening because guard cells are malfunctioning.
14.6 Why can't the parenchyma be made of two layers of palisade mesophyll? Carbon dioxide wouldn't be able to get into the leaf and oxygen wouldn't be able to get out.
14.7 In the first section of this module, you learned about the four basic tissues in a plant: dermal, ground, meristematic, and vascular. In this ection, you learned about the epidermis, the parenchyma, and the collenchyma.
14.7(continued) Classify each of these tissues within one of the four basic tisue types. Dermal- epidermis. Ground- parenchyma, collenchyma.
14.8 There are a few leaves, such as the floating leaves of a water lily plant, in which the stomata and the spongy mesophyll are on the top side of the leaf while the palisade mesophyll is on the bottom.
14.8(continued) In these leaves, which side will have the darker green color? The bottom.
14.9 If a leaf isn't green, does that mean there is no chlorophyll in it? No.
14.10 If a green leaf has no abscission layer, what color will the leaf be in the winter? Green.
14.11 A 12-foot high plant has a root system that travels to a soil depth of only three feet. Does this plant have a taproot system or a fibrous root system? Fibrous root system.
14.12 Classify each tissue labeled in Figure 14.11 as ground tissue, dermal tissue, meristematic tissue, or vascular tissue. Ground- cortex, endodermis. Dermal- epidermis. Meristematic- pericycle. Vascular- xylem, phloem.
14.13 If a root contains little cortex tissue compared to similar roots, what function can you conclude the root does not perform? Store substances.
14.14 If a stem has no cork, is it woody or herbaceous? Herbaceous.
14.15 If a stem has no limits to its growth, is it woody or herbaceous? Woody.
14.16 A stem has xylem and phloem packed together in fibrovascular bundles scattered throughout the stem. Is it woody or herbaceous? Herbaceous.
14.17 You see a plant that is two feet tall. Can it be a bryophyte? No.
14.18 You study a moss that reproduces by making spores. Is it composed of diploid or haploid cells? Does it make the spores using mitosis or meiosis? If you study the offspring of the reproduction, will its cells be haploid or diploid? Diploid. Meiosis. Haploid.
14.18(continued) What kind of cells will it make in order to reproduce? Will it use mitosis or meiosis to make these cells? Gametes. Mitosis.
14.19 A biologist studies a fern leaf with sorri. Is the fern leaf made of diploid or haploid cells? Diploid.
14.20 A student sees a fern growning on the branch of another tree. The student says that the fern is obviously a parasite. Is the student correct? Why or why not? No. Because it only absorbs the water and nutrients that have collected in the crackes of the tree's outer bark.
14.21 Suppose a conifer self-fertilizes. From a genetic point of view, is this the same as asexual reproduction. Why or why not? No. Because the offspring will not be exactly the same.
14.22 Construct a biological key for the classification of plants. Assume that the specimen you are examining is definitely a part of kingdom Plantae and is in one of the phyla we have discussed.
14.22(continued) For phyla other than Anthophyta, simply stop at the phylum level. If the plant is a part of phylum Anthophyta, classify it down to the class level, using the fundamental distinction between monocots and dicots.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
