To determine: The advantages of a plant having dead support cells like sclerenchyma.
Introduction: Most of the plant body includes ground tissue system as it is a necessary portion of the plants to supply mineral, nutrients, and water to the organisms. The ground tissue system includes three types of tissues: parenchyma tissue, collenchyma tissue, and sclerenchyma tissue. These tissues perform several varieties of functions in the plant body.

- Thick cell wall material that provides sturdiness to plant parts is called ____________ tissue. Plant stems with vascular tissue dispersed in the ground tissue are called _____________. Pore openings in plant leaves are called ______________. What soil element is necessary for the synthesis of plant proteins? ______________. Plant transpiration takes place in what vascular tissue? ______________. A plant zygote with 3 sets of chromosomes is called a ___________ cell. In asexual plant reproduction, each new plant is called a ____________. A plant hormone responsible for fruit ripening is called ______________. A photoperiodic plant cycle which repeats every 24 hours is called a _________________. Plant response to sunlight is called _________________.arrow_forward(a). When making furniture, one prefers the heartwood or the sapwood ? Explain your reasons (b). Cutting a cross section of a herbaceous dicotyledonous stem and a monocotyledonous stem, you will notice the differences of the arrangement of tissues and vascular bundles. Compare the cross sections by labelled illustrationsarrow_forwardFill in the general characteristics of the three types of plant cells.arrow_forward
- Which plant structure contains the plant embryo, a food supply, and a protective covering? ANSWER CHOICE ARE IN THE PHOTO. thanks.arrow_forwardWhich of the following statements about age gradients within the plant body is FALSE? Select one: a. Age gradients within the plant body include an apical-basal gradient where the youngest cells are near the apices (tips of shoots and roots). b. Age gradients within the plant body reflect the plant cells’ lack of mobility due to their shared walls. c. Phloem is oldest toward the outermost cell layers of the tree trunk and xylem is oldest toward the innermost cell layers of a tree trunk. d. All of the statements are true. e. Age gradients within the plant cells include walls that are youngest immediately adjacent to the plasma membrane and progressively older toward the middle lamella.arrow_forwardIn a comparison of the water potential and turgor pressure of leaf cells before and after wilting, which of the following would you expect to find?arrow_forward
- The presence of the vascular tissue allows a plant to grow much larger than its gametophyte counterpart and non-vascular plants. What are two functions (not structures) of the vascular tissue that allow for this?arrow_forwardWhat type of meristem is shown? what kind of growth do these meristems provide in plants. How is this different from other meristematic tissues?arrow_forwardMatch the following plant cells and tissues with their definition: - v Collenchyma A. grouped in strands and help support young parts of the plant shoot. They have unevenly thickened primary cell walls. - v Sugar-conducting cells of the phloem B. are alive at maturity, but lack organelles. Each sieve-tube element is connected to a companion cell by plasmodesmata. Water-conducting cells of the xyleem v Sclerenchyma C. The two types of water-conducting cells, tracheids and vessel elements, are dead and lignified at maturity. - v Parenchyma D. rigid due to thick secondary walls containing lignin, dead at functional maturity and play a role in support in the plant. E. cells are flexible and provide the most diversity of functions (such as photosynthesis)arrow_forward

ANSWER CHOICES ARE IN THE PHOTO. thanks.arrow_forwardIn a comparison of the water potential and turgor pressure of leaf cells before and after wilting, which of the following would you expect to find? Select one: a. Water potential: wilted = not wilted; Turgor Pressure: wilted < not wilted b. Water potential: wilted > not wilted; Turgor Pressure: wilted < not wilted c. Water potential: wilted < not wilted; Turgor Pressure: wilted > not wilted d. Water potential: wilted < not wilted; Turgor Pressure: wilted < not wilted e.
