Life cycle of Ectocarpus and Fucus respectively are

D VINOD · Accepted Answer

## CORE INFORMATION
✓ **Answer**: D
## CONCEPT FRAMEWORK
	**Primary Concept**: Plant Life Cycles
	**Related Topics**: Alternation of Generations, Algal Life Cycles, Ploidy
	**Prerequisites**: Basic understanding of haploid and diploid stages, familiarity with plant life cycle terminology
## SOLUTION PATHWAY
**Given Information**:
	The question asks for the life cycle type of two specific algae: Ectocarpus and Fucus.
	The options provide different combinations of Haplontic, Diplontic, and Haplodiplontic life cycles.
**Method & Steps**:
	1. Recall the life cycle of Ectocarpus.
		Reasoning: Ectocarpus exhibits a haplodiplontic life cycle, meaning it has both haploid and diploid multicellular stages.
		Formula/Rule: None
	2. Recall the life cycle of Fucus.
		Working: Fucus exhibits a diplontic life cycle, where only the diploid stage is multicellular and the haploid stage is represented only by gametes.
		Key Point: Fucus is an exception among many algae which are usually haplontic or haplodiplontic.
	3. Combine the information to determine the correct order.
		Result: The correct order is Haplodiplontic for Ectocarpus and Diplontic for Fucus.
		Verification: Option D matches the determined life cycle types.
 ## OPTION ANALYSIS
[A] :x: Incorrect. Ectocarpus is haplodiplontic, but Fucus is not haplontic.
[B] :x: Incorrect. Neither Ectocarpus nor Fucus has a haplontic or diplontic life cycle respectively.
[C] :x: Incorrect. Ectocarpus is not diplontic, and Fucus is not haplodiplontic.
[D] ✓: Correct. Ectocarpus is haplodiplontic and Fucus is diplontic.
 ## LEARNING AIDS
	**Common Mistakes**:
		1. Confusing the terms haplontic, diplontic, and haplodiplontic:  Carefully review the definitions. Haplontic has a dominant haploid phase, diplontic has a dominant diploid phase, and haplodiplontic has both.
		2. Misremembering the life cycles of specific algae: Study examples of different algae with their corresponding life cycle patterns.
	**Quick Tips**:
		1. Use mnemonic devices: Create a memory aid to help remember which algae have which life cycle.
		2. Visualize the life cycles: Draw or imagine the different stages of each life cycle to aid in understanding.
