Which of the following is a set of characteristics corresponding to monocots ?

Options

A. Tap root system , leaves with reticulate venation , tetramerous floral parts and one cotyledon
B. Tap root system , parallel venation of leaves , pentamerous floral parts and one cotyledon.
C. Fibrous root system , reticulate venation of leaves , trimerous floral parts and two cotyledons
D. Fibrous root system , parallel venation of leaves , trimerous floral parts and one cotyledons

Answer

To determine the set of characteristics corresponding to monocots, we can analyze the key features that define monocotyledons (monocots) as opposed to dicotyledons (dicots). Here’s a step-by-step breakdown of the characteristics of monocots:

### Step 1: Identify the Cotyledon
- Monocots have **one cotyledon**. This is a defining feature of monocot plants.

### Step 2: Examine the Root System
- Monocots typically exhibit a **fibrous root system**. This means that the roots are thin and spread out, forming a network rather than a single dominant root.

### Step 3: Analyze Leaf Venation
- The leaf venation in monocots is generally **parallel venation**. This means that the veins run parallel to each other along the length of the leaf.

### Step 4: Look at Floral Parts
- The floral parts of monocots are usually in multiples of **three** (trimerous). This means that flowers typically have three or six petals, sepals, or other floral structures.

### Step 5: Summarize the Characteristics
- Based on the above points, the characteristics of monocots can be summarized as:
1. One cotyledon
2. Fibrous root system
3. Parallel venation in leaves
4. Floral parts in multiples of three

### Conclusion
The correct set of characteristics corresponding to monocots includes one cotyledon, a fibrous root system, parallel venation, and trimerous floral parts.
