NEET Questions / Botany / Anatomy of Flowering Plants / Meristems
A unique feature of the quiescent center in root apical meristem is its:
High mitotic activity and contributes to root cap formation
Low mitotic activity and acts as a reserve
High metabolic activity and synthesizes growth hormones
Absence of cell division and undergoes programmed cell death
Which combination of meristems is responsible for producing secondary vascular tissues?
Apical meristem and intercalary meristem
Lateral meristem and apical meristem
Vascular cambium and cork cambium
Intercalary meristem and cork cambium
The pericycle in roots contributes to the formation of which of the following structures, EXCLUDING:
Lateral roots
Vascular cambium
Cork cambium
Root cap
Which statement accurately describes the difference between the fascicular and interfascicular cambium?
Fascicular cambium produces secondary xylem, while interfascicular cambium produces secondary phloem.
Fascicular cambium is present in monocots, while interfascicular cambium is present in dicots.
Fascicular cambium arises within vascular bundles, while interfascicular cambium arises in the medullary rays.
Fascicular cambium is a primary meristem, while interfascicular cambium is a secondary meristem.
In plants exhibiting unusual secondary growth, like in Bougainvillea, the additional cambia arise from:
Residual procambium cells
Cells of the pith
Cells of the cortex or pericycle
Differentiated xylem parenchyma
The concept of 'Dedifferentiation' in relation to meristem formation is best exemplified by:
Activity of the root apical meristem
Formation of interfascicular cambium from parenchyma cells
Development of phellogen from the epidermis
Differentiation of xylem vessels from procambium
Which tissue is responsible for the primary growth of plants, increasing their length and girth?
Apical meristem
Lateral meristem
Intercalary meristem
Ground tissue
Intercalary meristems are found in which part of the plant?
Base of leaves and internodes
Root tips
Shoot tips
Vascular cambium
Which meristem is responsible for increasing the diameter of stems and roots?
Lateral meristem
Apical meristem
Intercalary meristem
Ground meristem
What type of cells are found in meristematic tissue?
Actively dividing cells
Dead cells
Differentiated cells
Storage cells
