Question
Chapter 36, Problem 3CQ
Summary Introduction
To explain: The reason why most tall plants are woody and not herbaceous.
Introduction: Plant stems may be woody or herbaceous. Wood refers to the secondary growth of stems. Bark refers to the outermost layer of stems and is divided into the inner bark and outer bark. Bark is usually thinner as compared to the rings of woody tissue.

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.
STEP 4: Examine a living or preserved…

- T/F Question Parenchyma is soft, internal plant tissue. Xylem and phloem are plant structural tissue. Periderm tissue is a type of plant epidermis in young stems and roots. Plant shoots include stems, leaves, and flowers. Monocot stems have their vascular bundles arranged in a ring pattern in the ground tissue. Eudicots have their leaf veins arranged in a parallel pattern. Photosynthesis in leaves takes place in the mesophyll layer Eudicots possess a large taproot. The limiting factor for plants is phosphorus. Root hairs help to decrease the absorbtive surface area of a plant. Xylem conducts plant sugars and organic molecules. Plant tissues grow from meristem cells that continually divide during the growing season. Primary plant growth involves thickening of the stems and roots. Plants can undergo asexual reproduction without cross-pollination. The fertilization process in plants is a double fertilization process. Over 1/3 of the U.S. food supply comes from the cross-pollination…arrow_forwardThe presence of the vascular tissue allows a plant to grow much larger than its gametophyte counterpart and non-vascular plants.
