Question

A unique feature of angiosperm embryogenesis is the formation of a suspensor. Which statement regarding the suspensor is INCORRECT?

Mr. NARESH KUMAR K · Accepted Answer

## CORE INFORMATION
✓ **Answer**: D
## CONCEPT FRAMEWORK
	**Primary Concept**: Angiosperm Embryogenesis and the role of the suspensor.
	**Related Topics**: Plant Reproduction, Seed Development, Embryo Development
	**Prerequisites**: Basic understanding of plant structures and reproduction.
## SOLUTION PATHWAY
**Given Information**:
	The question asks for the INCORRECT statement about the suspensor's role in angiosperm embryogenesis.
**Method & Steps**:
	1. **Analyze each option based on the function of the suspensor:**
		Reasoning: The suspensor plays a vital role in nourishing and positioning the embryo but does *not* form the embryo itself.
	2. **Identify the statement that contradicts the suspensor's function:**
		Working: Option D states that the suspensor undergoes extensive cell divisions to form the embryo proper. This is incorrect.
		Key Point: The embryo proper develops from the zygote through a series of cell divisions, *not* the suspensor.
	3. **Confirm the correct answer:**
		Result: Option D is the incorrect statement.
		Verification: The suspensor supports the developing embryo, but the embryo proper is formed from the zygote.
 ## OPTION ANALYSIS
[A] ✓: It connects the developing embryo to the maternal tissues.  This is a correct statement. The suspensor acts as a bridge between the developing embryo and the maternal tissues, facilitating nutrient transport.
[B] ✓: It provides a conduit for nutrients and growth regulators. This is a correct statement. The suspensor acts as a channel for the transfer of essential nutrients and growth regulators from the maternal tissues to the developing embryo.
[C] ✓: It pushes the embryo into the endosperm. This is a correct statement.  The suspensor helps position the developing embryo within the endosperm, which serves as the food source for the embryo.
[D] :x: It undergoes extensive cell divisions to form the embryo proper. This is the incorrect statement. The suspensor does *not* form the embryo proper. The embryo proper develops from the zygote.
 ## LEARNING AIDS
	**Common Mistakes**:
		1. Confusing the role of the suspensor with the development of the embryo proper: Remember that the suspensor *supports* embryo development, but the embryo itself originates from the zygote.
		2. Overlooking the importance of the suspensor:  The suspensor is crucial for nutrient transfer and positioning the embryo.
	**Quick Tips**:
		1. Remember 'S' in Suspensor for 'Support':  The suspensor primarily *supports* the developing embryo.
		2. Visualize the suspensor as a 'bridge' or 'umbilical cord': This helps in remembering its function of connecting the embryo to the maternal tissues and transferring nutrients.
