While walking in the woods, you encounter an unfamiliar flowering plant. Which of the following plant features would help you determine plant is a
- a. size of the plant
- b. number of seed leaves
- c. shape of its root system
- d. number of petals in its flowers
- e. arrangement of vascular bundles In Its stem
- f. whether or not it produces seed-bearing cones
To examine: Which plant features would help to determine whether that plant is a monocot or a eudicot.
Introduction: Angiosperms are that plants that have flowers and produce seeds that are enclosed within a carpel. The plants can be classified on the basis of structural difference into monocots and eudicots. The name of the embryonic structure of seed leaves is called cotyledons. A monocot has one seed leaf, whereas a eudicot has two seed leaves.
Answer to Problem 1SQ
Correct answer:
Option b. is given as “number of seed leaves”.
Option c. is given as “shape of the root system”.
Option d. is given as “number of petals in its flowers”.
Option e. is given as “arrangement of vascular bundles in its stem”.
Therefore, options b., option c., option d., and option e. are correct.
Explanation of Solution
Reasons for the correct statement:
Monocot has one cotyledon, fibrous root, flowers multiple of three, and vascular bundles are arranged complexly.
Eudicot has two cotyledons, taproot system, flowers usually multiple of four or five, and vascular bundles are arranged in a ring.
Hence, option b., option c., option d., and option e. are correct.
Reasons for the incorrect statement:
Option a. is given as “size of the plant”, but both monocot and eudicot have different sizes of plants. Hence, this cannot be used to differentiate between them.
So, option a. is incorrect.
Option f. is given as “whether or not it produces seed-bearing cones”, but seed-bearing cone is not a feature of monocot or eudicot.
So, option b. is incorrect.
Hence, options a. and f. are incorrect.

- READ THE FOLLOWING INSTRUCTIONS: Bryophytes in which the gametophytes are "leafy" in appearance and the sporophytes grow conspicuously from the tips of the gametophyte plants. STEP 1: Examine the mass of moss plants and then select one or two individual gametophyte plants and note the leaf-like (not true leaves because they lack conducting tissue) structures which are arranged around a central, vertical "stem-like" stalk and root-like rhizoids which anchor the plant and absorb water and nutrients. STEP: The sex organs are in the tips of the plants and must be seen with the microscope. Study a slide of a vertical section through head of a mate plant and note the many antheridia. STEP 3: Examine a slide through a vertical section of a female plant. Note the many upright archegonia each on a tall stalk and each with a swollen base or venter containing an egg and an elongate neck. Note the filamentous paraphyses between the archegonia.

Stems can contain stomata.arrow_forwardAs part of an experiment you are required to observe the external features of a fern. State what microscope would you use and give reasons why? You have been provided with a plant showing the rooting system and the stem with several leaves. Give SIX features that you will look for to determine whether this is a monocotyledonous plant or a dicotyledonous plant. Present your answer in a clear, logical manner. In an experiment students were given the following materials and apparatus: - juices from three local fruits; 4% glucose solution; Benedict's solution; test tubes, beakers, syringes and boiling water bath. Describe CLEARLY the procedure that can be used to estimate the amount of glucos present in each juice. Use numbered steps in your answer.arrow_forward

Back at the lab, you observe the characteristic structure of the plant and make some notes. Then, you carefully dissect the stems and leaves and look at the tissue under the microscope. Finally, you are able to determine the type of plant it is. Use the notes below to identify the class to which this plant belongs. Notes on physical characteristics of the specimen: the plant has no leaves or roots, but has hair-like rhizomes which anchors it in the soil the stems are highly branched sporangia are present at the ends of each stem dissection of the stem shows the presence of vascular tissue in the form of a xylem and phloemarrow_forward
