19.   Which of the following statements is correct in regard to apical and floral meristems? 
Butoxors [25]
The correct statement is D. APICAL MERISTEMS ARE SOMETIMES CHANGED INTO FLORAL MERISTEMS.

Apical Meristems are found in the tips of the roots and in the buds of the shoots. They supply cells for the plants to grow in length.

Apical Meristems are found in herbaceous plants, woody plants, grasses, and flowering plants.

In flowering plants, shoot apical meristem develops into an inflorescence meristem which produces the floral meristem. The floral meristem is responsible for the production of the sepals, petals, stamens, and carpels of the flower.

using similarities in body symmetry and other anatomical features to assign an organism to a clade involves 1. cladistics based
Jlenok [28]

The process of classifying an organism into a clade by comparing similarities in body symmetry and other morphological traits comprises - 1. body plan-based cladistics cladistics based on body plan, morphology-based phylogeny.

<h3>What is cladistics based on body plan ?</h3>

A method of biological taxonomy that organizes taxa in a branching hierarchy so that all members of a given taxon share the same ancestors and defines taxa uniquely by shared traits not present in ancestral groupings.

  • Cladistics is a method of biological classification in which groups of species (or "clades") are assigned based on theories of most recent shared ancestry.
  • The evolutionary link between recent ancestors and descendants, or the course of evolution, is shown via cladistics. An aid to representing it is a cladogram. Since clades serve as the foundation for phylogenetic trees, cladistics is a component of the phylogeny.
<h3>What is molecular-based phylogeny ?</h3>

Molecule structure is used in molecular phylogeny to shed light on an organism's evolutionary connections.

  • A so-called phylogenetic tree represents the findings of a molecular phylogenetic research. DNA, RNA, and proteins are components of all living things.
  • Molecular phylogenetics creates a phylogenetic tree by drawing conclusions about the evolutionary links that derive from molecular evolution.

<h3>What is Morphology-based phylogeny ?</h3>

Using anatomical features, morphological phylogenetics infers evolutionary trees. Node: A branching point when an ancestral lineage splits into two (or more) daughter lineages in an evolutionary tree.

The ability to discuss the phylogeny of fossil taxa and how they relate to modern taxa is the unquestionable benefit of morphological data. However, their strategy prevents us from addressing the situation of extinct taxa for which there is no way to gather DNA data (i.e., almost all of them).
