Chapter 35, Problem 2A
Summary Introduction
Introduction:
Meristematic cells are the plant stem cells that divide continuously. These cells do not differentiate into other cells. There are three types of meristematic tissue present in the plant that are apical, lateral and intercalary meristematic tissues.

- Which of the following statements is NOT true of the stems of vascular plants? a. Stems are composed of repeating segments, including nodes and internodes. b. Primary growth only occurs at the shoot apical meristem. c. Vascular tissues may be arranged on the outside of the stem or scattered throughout the stem. d. Stems can contain stomata.arrow_forwardAn experiment is conducted to determine the effect of classical music on the growth rate of marigolds (flowers). Two groups of plants are grown from seed in identical soil types, exposed to identical light conditions, and given the same nutrients. Group A is in a quiet atmosphere. The plants in group B provided with the same atmosphere, except that classical music is played for twelve hours daily in this area. The scientist measures the plants in both groups each day and records the data. In experimental design, Group A is known as.* experimental group control group non-experimental group O quasi-experimental grouparrow_forwardRoot hairs form in the zone of a. cell division. b. elongation. c. maturation. d.

- Fifteen years ago, your parents hung a swing from the lower branch of a large tree growing in your yard. When you go and sit in it today, you realize it is exactly the same height off the ground as it was when you first sat in it 15 years ago. The reason the swing is not higher off the ground as the tree has grown is that a. the tree trunk lacks secondary growth. b. the tree trunk is part of the primary growth system of the plant, but elongation is no longer occurring in that part of the tree. c. trees lack apical meristems and so do not get taller. d. you are hallucinating, because it is impossible for the swing not to have been raised off the ground as the tree grew.arrow_forwardTerrestrial plants have stomata on the surface of their leaves. Stomata are surrounded by two guard cells that change shape in response to environmental factors and open or close the stoma. Which of the following best explains how the structure of the leaf is used in processes that occur in plants? A. Water enters the plant through the surface of the leaf for transpiration B. Gases for photosynthesis are exchanged through the surface of the leaf. C. Energy for cellular reproduction is absorbed through the surface of the leaf. D. Carbon dioxide enters the plant through the surface of the leaf for cellular reproduction.arrow_forwardA mutant plant has roots that grow in all directions.

What is indeterminate growth in plants? 3. What is de-differentiation in plant cells?arrow_forwardThese plant cells are are distinctive for having thickened corners of the cells when examined as a cross-section: Select one: a. Collenchyma b. Sclerenchyma c. Parenchyma d. Fibers e. Scleridsarrow_forwardPut the following 3 fictional plants in order from earliest to most recent according to their characteristics: A. The Terpad Plant: This plant reproduces using spores and has proper leaves and vascular tissue. B. The Feltris Plant: The Feltris plant lives in moist environments since it doesn't have any vascular tissue to maintain hydration throughout the plant. This plant has no roots either but has small root-like structures called rhizoids which help anchor them to the ground. Water is also required in order for fertilization. C. The Lancelot Plant: This plant can grow in either moist or dry environments, has true roots, stems and leaves and reproduces via seeds which develop within an ovary.arrow_forward
- The root cap needs to be continually supplied with new cells by the root apical meristem (RAM) because: Select one: a. the root cap needs to recruit new cells from the RAM to develop lateral root hairs. b. the population of root cap cells needs to be replenished from the RAM as older root cap cells differentiate into epidermal, cortex, and vascular tissues. c. root cap cells are damaged or become separated as elongation in the tissue produced by the RAM forces it through the soil. d. the root cap must add cells to cover the additional surface area created by the growing root tip. truck driver is transporting a load of unripened bananas in an air-tight vehicle and decides to stop and eat an apple after checking on his cargo. He opens the back of his truck and, while walking around the unripened bananas, he decides the apple is overripe and drops it. When the bananas are finally delivered days later, he is surprised to find that all of his bananas have ripened. Why has this occurred?…arrow_forwardWhich of the following adaptations allows plants to pause their life cycle until environmental conditions are optimal? a. Stomata b. Phloem and xylem c. Seeds d.
