Which of the following statements is/are false?
a. A cell is a group of tissues having a common origin and generally performing a common function. b. Within angiosperms, the monocots and dicots are seen to be anatomically different. c. During the formation of the primary plant body, specific regions of the apical meristem produce dermal tissues, ground tissues and vascular tissues.
Which of the following meristems appear(s) early in life of a plant and contribute(s) to the formation of the primary plant body?
a. Apical meristem b. Intercalary meristem c. Lateral meristem
Which of the following is not a property of monocotyledonous stem?
The increase in girth of a plant is called its secondary growth. Which of the following tissues is/are not involved in secondary growth?
a. Pericycle b. Vascular cambium c. Cork cambium
Which of the following statements is/are false?
a. The peripheral region of the secondary xylem is lighter in colour and is known as the heartwood. b. The spring wood is lighter in colour and has a lower density whereas the autumn wood is darker and has a higher density. c. Sapwood is involved in the conduction of water and minerals from root to leaf.
Which of the following statements is/are false?
a. The growth of the roots and stems in length with the help of apical meristem is called the primary growth. b. In the young stem, the meristematic layer is present in patches as a single layer outside the xylem. c. In dicot stems, the cells of cambium present between primary xylem and primary phloem is the intrafascicular cambium.
Which of the following properties is/are associated with a dicotyledonous root?
a. Many of the epidermal cells protrude in the form of unicellular root hairs. b. The cortex consists of several layers of thin-walled parenchyma cells with intercellular spaces. c. There are usually more than six xylem bundles in a dicotyledonous root.
Complex tissues work together as a unit and are made of more than one type of cells. Which of the following constitute the complex tissues in plants?
a. Xylem b. Sclerenchyma c. Phloem d. Collenchyma
The parenchymatous cells which lie between the xylem and the phloem are called
Stomata is composed of two bean-shaped cells known as guard cells. Which of the following is not a property of the guard cells?
Which of the following cells are living, thin-walled and have their cell walls made up of cellulose?
Match the following:
| a. Lateral meristem | 1. It is the meristem which occurs between mature tissues. |
| b. Apical meristem | 2. It is the meristem which occurs at the tips of roots and shoots, and produces primary tissues. |
| c. Intercalary meristem | 3. It is the meristem in which secondary growth occurs, resulting in increase in stem girth. |
The function of which of the following entities is to store food material and other substances like resins, latex and mucilage?
Of the three tissue systems, the vascular tissue system consists of which of the following entities?
a. Stomata b. Epidermal appendages c. Xylem d. Phloem
Match the following:
| a. Closed vascular bundle | 1. In this, the xylem and phloem are situated at the same radius of vascular bundles. |
| b. Radial vascular bundle | 2. In this, the vascular bundles have no cambium present in them and they do not form secondary tissues. |
| c. Cojoint vascular bundle | 3. In this, the xylem and phloem within a vascular bundle are arranged in an alternate manner on different radii. |
