Endospermic, perispermic, polycotyledonous, and winged seeds having member of plantae also show

Options

A. Sulfur shower
B. Largest ovule
C. Double fertilization
D. Placentation

Answer

To solve the question regarding the characteristics of endospermic, perispermic, polycotyledonous, and winged seeds in members of the Plantae kingdom, we need to analyze each term and relate them to the options provided. Here’s a step-by-step breakdown:

### Step-by-Step Solution:

1. **Understand Endospermic Seeds**:
- Endospermic seeds are those that contain endosperm, which serves as a food reserve for the developing embryo.
- Example: Seeds of plants like wheat and maize.

**Hint**: Think about the role of endosperm in seed development.

2. **Understand Perispermic Seeds**:
- Perispermic seeds have remnants of the nucellus in the embryo sac, which also contributes to the nutrition of the developing embryo.
- Example: Black pepper (Piper nigrum).

**Hint**: Consider how the nucellus contributes to seed structure.

3. **Understand Polycotyledonous Seeds**:
- Polycotyledonous seeds contain more than one cotyledon.
- Example: Plants like peanuts and certain legumes.

**Hint**: Recall what cotyledons are and their role in seedling development.

4. **Understand Winged Seeds**:
- Winged seeds have a flattened, wing-like structure that aids in wind dispersal.
- Example: Seeds of the maple tree.

**Hint**: Think about how seed dispersal mechanisms work in plants.

5. **Analyze the Options**:
- **Sulphur Shower**: Associated with gymnosperms, not angiosperms.
- **Largest Ovule**: Typically found in gymnosperms like Cycas.
- **Double Fertilization**: A unique feature of angiosperms where one sperm fertilizes the egg (forming the zygote) and another sperm fuses with two polar nuclei to form the endosperm.
- **Placentation**: Refers to the arrangement of ovules within the ovary, not a defining feature of angiosperms.

6. **Identify the Correct Answer**:
- Among the options, **double fertilization** is the characteristic feature that aligns with the characteristics of endospermic, perispermic, polycotyledonous, and winged seeds, as all these features are found in angiosperms.

### Final Answer:
The characteristic feature that members of Plantae with endospermic, perispermic, polycotyledonous, and winged seeds also show is **double fertilization**.
