Question

A scientist discovers a new species with the following characteristics: eukaryotic, multicellular, photosynthetic, lacks vascular tissue, exhibits alternation of generations with a dominant gametophyte.  This organism MOST likely belongs to which plant group?

D VINOD · Accepted Answer

## CORE INFORMATION
✓ **Answer**: B
## CONCEPT FRAMEWORK
 **Primary Concept**: Plant classification based on characteristics
 **Related Topics**: Bryophytes, Pteridophytes, Gymnosperms, Angiosperms, Alternation of generations, Vascular tissue
 **Prerequisites**: Basic understanding of plant groups and their distinguishing features.
## SOLUTION PATHWAY
**Given Information**:
  * Eukaryotic
  * Multicellular
  * Photosynthetic
  * Lacks vascular tissue
  * Dominant gametophyte in alternation of generations
**Method & Steps**:
 1. Identify key characteristics:
  Reasoning: The presence of a dominant gametophyte and the absence of vascular tissue are crucial for determining the plant group.
 2. Compare with plant groups:
  Working: Let's analyze the given options:
   * **Bryophytes (mosses, liverworts, hornworts):** These plants are non-vascular, possess a dominant gametophyte generation, and are multicellular, eukaryotic, and photosynthetic. This matches all the given characteristics.
   * **Pteridophytes (ferns):** These plants are vascular and have a dominant sporophyte generation.
   * **Gymnosperms (conifers):** These plants are vascular and have a dominant sporophyte generation.
   * **Angiosperms (flowering plants):** These plants are vascular and have a dominant sporophyte generation.
 3. Determine the most likely group:
  Result: Based on the given characteristics, the organism most likely belongs to the Bryophyta group.
  Verification: All characteristics match the description of Bryophytes.
 ## OPTION ANALYSIS
A :x: Pteridophytes have vascular tissue and a dominant sporophyte.
B ✓: Bryophytes lack vascular tissue and have a dominant gametophyte, matching all given characteristics.
C :x: Gymnosperms have vascular tissue and a dominant sporophyte.
D :x: Angiosperms have vascular tissue and a dominant sporophyte.
 ## LEARNING AIDS
 **Common Mistakes**:
  1.Confusing dominant gametophyte with dominant sporophyte: Remember that Bryophytes have a dominant gametophyte, while other plant groups have a dominant sporophyte.
  2.Overlooking the significance of vascular tissue: The presence or absence of vascular tissue is a major distinguishing factor between plant groups.
 **Quick Tips**:
  1.Create a table summarizing the key characteristics of different plant groups to aid in quick identification.
  2.Focus on the presence/absence of vascular tissue and the dominant generation (gametophyte or sporophyte) for quick classification.
