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.

- Which of the following cell types forms most of the inside of a plant? a. meristem cells b. collenchyma cells c. sclerenchyma cells d. parenchyma cellsarrow_forwardThick 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_forward
- Which 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_forwardThe 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_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
- What type of meristem is shown? what kind of growth do these meristems provide in plants. How is this different from other meristematic tissues?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. Water potential: wilted > not wilted; Turgor Pressure: wilted > not wiltedarrow_forwardThis is about vegetative organs in Botany course. In what groups and in what conditions are root hairs absent in root systems of plants? Why are root hairs not formed at the region of elongation and after the region of maturation? Briefly explain why growth in plants is said to be indeterminate. Is there a significance of compound leaves relative to strong winds? How about leaf-eating animals? Justify your answer.arrow_forward
- Identify and indicate each plant's specialized function. The following are the available choices. Choices can be repeated and answers can be two or more. Just write the letter with the correct answers. A. Reproduction (plantlets or buds may grow along with blades and petioles' notches, bases, apices, and tips.) B. Aeration (Increase petiole size to increase buoyancy) C. Support (As in the banana plant, the presence of tendrils, hooks, and supporting leaf bases.) D. Protection (Bud scales, motile leaves, spines, stipules, and bracts are all present.) E. Water storage (This is particularly important in desert plants with succulent leaves that store water in their large, thin-walled parenchyma cells. Certain plants, such as onions and lilies, store food in their leaves.) F. Attraction (Some plants have petaloid flower bracts or brightly variegated leaves.) G. Absorption (Insectivorous leaves, particularly unscrutinized leaves on some aquatic plants.) 1. Cadena de amor: 2. Rose: 3.…arrow_forwardPlant Physiology Define or describe and give 2 functions of the plant tissue: Meristemarrow_forwardWhat are the flaws ? Meristematic tissue is the site of mitosis and therefore growth for a plant. Apical meristem is found at the tips of roots and shoots and allows them to produce flowers. Lateral meristem is found along the length of the plant and allows it to increase in width. Intercalary meristem is found in nodes along grasses and allows them to grow from the “base”, which is why grass continues to grow after it is cut. Plants have three organs: leaves, stems, and roots. While the functions of the organs are the same between plants, the structure is different between two large groups of plants: monocots and dicots. Leaves are the site of photosynthesis. In monocots, the vascular tissue is in parallel veins like in grass. In dicots, the veins form a web or net pattern like in a maple leaf. A bulb is a modified leaf that allows the plant to store food. Stems make up the “body” of the plant and support the leaves. In monocots, vascular bundles are found randomly throughout the…arrow_forward
