Question

In the life cycle of a moss, the sporophyte is:

K SURESH KUMAR · Accepted Answer

## CORE INFORMATION
✓ **Answer**: [B]
## CONCEPT FRAMEWORK
	**Primary Concept**: Moss Life Cycle
	**Related Topics**: Plant Reproduction, Gametophyte vs. Sporophyte
	**Prerequisites**: Understanding of plant biology and life cycles.
## SOLUTION PATHWAY
**Given Information**:
		1. The sporophyte is one of the two main phases in the moss life cycle.
		2. The sporophyte develops from the fertilized egg (zygote).
**Method & Steps**:
	1. Identify the relationship between the sporophyte and gametophyte.
		Reasoning: The sporophyte is dependent on the gametophyte for nutrition, as it remains attached and relies on it for sustenance.
		Formula/Rule: The sporophyte is not independent in this phase of the life cycle.
	2. Determine the role of the sporophyte in the life cycle.
		Working: The sporophyte produces spores through meiosis, which will grow into new gametophytes.
		Key Point: The sporophyte is typically not the dominant phase in mosses; that role is held by the gametophyte.
	3. Confirm the nutritional dependency of the sporophyte.
		Result: The sporophyte is indeed dependent on the gametophyte for nutrition.
		Verification: This relationship is a defining feature of moss biology.
## OPTION ANALYSIS
[A] :x: Incorrect; while the sporophyte can perform some photosynthesis, it is primarily dependent on the gametophyte.
[B] ✓: Correct; the sporophyte is indeed dependent on the gametophyte for nutrition.
[C] :x: Incorrect; the gametophyte is the dominant phase in the moss life cycle, not the sporophyte.
[D] :x: Incorrect; the sporophyte is responsible for producing spores, not gametes.
## LEARNING AIDS
	**Common Mistakes**:
		1. Confusing the roles of gametophyte and sporophyte: Remember, in mosses, the gametophyte is dominant and the sporophyte is dependent.
		2. Misunderstanding the definition of gametes vs. spores: Gametes are produced by the gametophyte, while spores are produced by the sporophyte.
	**Quick Tips**:
		1. Memorize that 'gametophyte = green, independent, dominant'; 'sporophyte = dependent, spore-producing'.
		2. Visualize the life cycle of moss to reinforce the relationship and roles of each phase.
