Test: Plant Tissue - 1 - Question 6

Bamboo, grass and mint stem elongate by the activity of -

Detailed Solution for Test: Plant Tissue - 1 - Question 6

Bamboo, grass and mint stem elongate by the activity of Intercalary meristems. Intercalary meristem at base of leaves or nodes of grasses is responsible for primary growth. Meristems are classified by their location as apical located at root and shoot tips, lateral in the vascular and cork cambia, and intercalary at internodes, or stem regions between the places at which leaves attach and leaf bases. Intercalary meristem cells possess the ability to divide and produce new cells, as do apical and lateral meristems. They differ, however, in being situated between regions of mature tissue, such as at the base of grass leaves, which are themselves located on mature stem tissue.
Thus, the correct answer is option C.

Test: Plant Tissue - 1 - Question 7

Test: Plant Tissue - 1 - Question 10

Root cap is not found in -

Detailed Solution for Test: Plant Tissue - 1 - Question 10

Many plants growing in aquatic habitats do not possess roots because there is little requirement for absorption of water and mineral salts, e.g., Wolffia, Utricularia, Myriophyllum, Ceratophyllum. In other aquatic plants, roots develop only for balancing (e.g., Lemna, Pistia) and fixation (e.g., Hydrilla). The root cap is a section of tissue at the tip of a plant root. It is also called as calyptra. Root caps contain statocytes which are involved in gravity perception in plants. If the cap is carefully removed the root will grow randomly. The root cap protects the growing tip in plants. It secretes mucilage to ease the movement of the root through soil and may also be involved in communication with the soil microbiota. Since, roots in Pistia are only for balancing, root cap is not required. So, root cap is absent in Pistia

Thus, the correct answer is option B.

Which of the following is a secondary meristem 

Detailed Solution for Test: Plant Tissue - 1 - Question 13

The cork cambium is a lateral meristem and is responsible for secondary growth that replaces the epidermis in roots and stems. It is found in woody and many herbaceous dicots, gymnosperms and some monocots (monocots usually lack secondary growth).

Test: Plant Tissue - 1 - Question 14

In plants, during embryonic condition

Detailed Solution for Test: Plant Tissue - 1 - Question 14

Embryonic tissue in plants refers to the actively growing cells but more than often this term is used to describe the early formation of tissue during its first growth stages. It thus refers to the sporophyte, gametophyte embryos from seedlings as well as meristematic tissues which are always in embryonic state. Under this condition, the growth of this tissues takes place through cell division and the cells of the embryo divide.
Therefore, the correct answer is option C.

Test: Plant Tissue - 1 - Question 15

The secondary meristem originates from

Detailed Solution for Test: Plant Tissue - 1 - Question 15

On the basis of origin and development, meristem is grouped as promeristem, primary and secondary meristem. Promeristem includes undifferentiated, actively dividing apical initials which are derived from embryonic tissues and give rise to primary meristem. Primary meristem is derived from promeristem or embryonic meristem and produce primary permanent tissues of primary plant body. Secondary meristem develops from permanent tissues during secondary growth and gives rise to secondary tissues. Secretory tissues are the permanent primary tissues, which are derived from promeristem.

Thus, the correct answer is option B

Test: Plant Tissue - 1 - Question 16

The growth of plant tissues in artificial media is called​

Detailed Solution for Test: Plant Tissue - 1 - Question 16

Test: Plant Tissue - 1 - Question 17

The function of root cap is

Detailed Solution for Test: Plant Tissue - 1 - Question 17

The root cap protects the growing tip in plants. It secretes mucilage to ease the movement of the root through soil, and may also be involved in communication with the soil microbiota. The purpose of the root cap is to enable downward growth of the root, with the root cap covering the sensitive tissue in the root.

Test: Plant Tissue - 1 - Question 18

In quiescent zone, DNA content is -

Detailed Solution for Test: Plant Tissue - 1 - Question 18

The cells contain lower concentration of RNA, DNA and protein than other cells of root apex.

Quiescent centre is unusual in shoots, but it is universal in roots of higher plants. Though the occurrence of QC was reported in vascular cryptogams (e.g. Equisetum arvense) later investigations have established that the entire root apex of vascular cryptogams is mitotically active. Quiescent centre maintains a strict boundary in closed meristem. As a result the derivatives of QC also maintain a strict boundary in the apical zone.

Test: Plant Tissue - 1 - Question 19

Which among the following is incorrect about Sclerenchyma?

Detailed Solution for Test: Plant Tissue - 1 - Question 19
  • Sclerenchymatous cells are the dead cells responsible for stiffness in plants.

Parenchyma cells are living cells. They are at the constant state of division. They have large central vacuoles, which allow the cells to store and regulate ions, waste products and water. These are majorly distributed as ground tissue. Tissue specialised for food storage is commonly formed of parenchyma cells. 
Collenchyma and sclerenchyma involve in mechanical support. 
Aerenchyma involves in gas exchange.
Thus, option A is correct.

Test: Plant Tissue - 1 - Question 29

Cells of parenchymatous tissues are characterised by :-

Detailed Solution for Test: Plant Tissue - 1 - Question 29

Parenchyma is a simple tissue which is composed of thin-walled polyhedral, isodiametric living cells with sufficient cytoplasm and one or more nuclei. These tissues serve the purpose of storage, photosynthesis gaseous exchange and much more but do not provide mechanical support to the plant and hence, lack cell wall thickening or lignin deposition which is a characteristic feature of mechanical tissues. They have cellulosic cell wall without any thickening or lignin deposition. Parenchymatous cells are characterized by the presence of well-developed intercellular spaces, as in the case of aerenchyma.
Therefore, the correct answer is option D.
