To identify: The structure shown in micrograph A.
Concept introduction: Vascular plants consist of two specialized tissues called as xylem and phloem that act as a conducting tube in plants for the transportation of water and sugar molecules throughout the plant. Xylem is a vascular tissue involved in the transportation of water and minerals from the root to the leaves of plants. It also provides mechanical support and storage to the plants. Xylem consists of two types of conducting cells namely tracheids and vessel elements. Both cells are together called as tracheary element.

- Look at As shown. Part (A) shows the lower half of a fusiform initial (actually most fusiform initials would be much taller than this), and part (B) shows the same cell after it has divided and one of the daughter cells is developing into a xylem cell. Did the fusiform initial divide with a periclinal wall or an anticlinal wall as it went from part a to part b? Part (D) shows that the same fusiform initial has now produced a second cell that is developing into a phloem cell. Was that phloem cell produced by a periclinal or an anticlinal division of the fusiform initial? Part (F) shows the fusiform initial dividing and forming a second fusiform initial. Is this division occurring by a periclinal wall or an anticlinal wall?arrow_forward2. a) As 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? b) 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. c) 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 glucose present in each juice. Use numbered steps in your answer.arrow_forwardSince you're done with your study of plant tissues, you may now answer the questions about them below. 1. How do meristems accomplish the production of new, mitotically healthy cells? 2. What is indeterminate growth in plants? 3. What is de-differentiation in plant cells?arrow_forward
- 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…arrow_forwardIdentify the pointed cell and its function. How is it different from other plant cell types? How can you describe the cell walls?

- Show the sequence of secondary growth by drawing the row of cells from the boxed area below and labeling the vascular cambium cell (V), 5 xylem cells from oldest (X1) to youngest (X5), and 3 phloem cells (P1 to P3). Show what happens after growth continues by drawing and labeling a row with twice as many xylem and phloem cells. How does the vascular cambium’s location change? A pear has a hard texture but juicy.
