What is a shoot apical meristem? What is the apical surface of epithelial tissue? What are the two locations of the apical meristem? What is the function of the apical bud? What is an apical bud in plants? What is the difference between apical meristems and lateral buds?
1. 1. Reviewing the literature on apical dominance in the light of the "PESIGS" rules formulated in the preceding paper (Jacobs, 1959) made clear that earlier researchers had never demonstrated exact substitution of synthetic auxin for the native auxin of the apex. 2. 2. Our clone of ...
Apical dominance is the phenomenon in which dominance is exercised by the apical portions of the shoot over other parts of the plant. Apical dominance leads to the growth of the main shoot and inhibits the growth of other shoots. The plant hormone auxin plays a significant role in maintaining...
leaf is evident in all land plants; prominent in vascular plants but to a lesser extent in bryophytes, observed mainly in the midrib region referred to as ‘costa’. Besides this attribute of dorsiventrality, leaves become determinate, planar, and laminar structures. Considering all these views,...
A large part of total biomass is stored as compounds that form the structure of plants: cellulose and lignin in the cell walls, lipids in the membranes, and proteins within the cell (Fig. 1e). Another part of total biomass is stored in the form of nonstructural carbohydrates (NSCs; ...
The development of PH largely depends on altered morphometric characteristics of the shoot apical meristem (SAM) (Fig. 1). In higher plants, SAM consists of the central zone (CZ), the organizing center (OC), and the rib zone (RZ) located below the CZ. The RZ is responsible for the elo...
The evolution of plants to efficiently transport water and assimilates over long distances is a major evolutionary success that facilitated their growth and colonization of land. Vascular tissues, namely xylem and phloem, are characterized by high specia
Melatonin is a hormone that controls how we feel when we are awake. Plants also have hormones and these chemicals are called plant hormones. These are different than the hormones found in animals. Plant hormones fall into five main classes: Auxins are produced in terminal buds and suppress the...
Plants are multicellular organisms that require cell division in the form of mitosis in order to grow and to replace old cells. The goal of mitosis is to produce two daughter cells that are genetically identical to their single parent cell....
What is the primary role of auxin in plants? Auxin promotes cell elongation, root growth, and regulates phototropism and gravitropism. 6 How does auxin contribute to apical dominance? Auxin suppresses lateral bud growth, maintaining the dominance of the main stem. 6 What effect does auxin have ...
