In a dicot stem undergoing secondary growth, which tissue is primarily responsible for the increase in girth?
Cork Cambium
Vascular Cambium
Apical Meristem
Intercalary Meristem
Which of the following BEST explains the physiological significance of the quiescent center in the root apical meristem?
Promotes rapid cell differentiation to form specialized root tissues
Acts as a reserve of stem cells, protecting the meristem from damage and ensuring continuous growth
Synthesizes hormones that inhibit root elongation and promote branching
Regulates the uptake of water and nutrients from the soil
What is the primary function of the root cap?
Absorbing water
Anchoring the plant
Storing food
Protecting the root apical meristem
Which part of the stem is responsible for the primary growth of a plant?
Apical meristem
Lateral meristem
Intercalary meristem
Cork cambium
The region of the root where cell division takes place is the:
Elongation zone
Maturation zone
Meristematic zone
Root cap
Which feature distinguishes the sporophyte of Anthoceros from those of other bryophytes?
Complete dependence on the gametophyte
Presence of a foot, seta, and capsule
Presence of a basal meristem and indeterminate growth
Lack of stomata
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.
