Write down differences between dicots and monocots.

Answer

### Step-by-Step Text Solution

1. **Definition of Cotyledons**:
- Monocots have one cotyledon (seed leaf), while dicots have two cotyledons. Cotyledons are the first leaves that appear from a germinating seed and serve as a food reserve for the developing plant.

2. **Venation Patterns**:
- Monocots exhibit parallel venation in their leaves, meaning the veins run parallel to each other. In contrast, dicots show reticulate (or net-like) venation, where the veins form a branching pattern.

3. **Vascular Bundles Arrangement**:
- In monocots, the vascular bundles (which contain xylem and phloem) are scattered throughout the stem. In dicots, these vascular bundles are arranged in a circular pattern or in rings.

4. **Root System**:
- Monocots typically have a fibrous root system, where many thin roots spread out from the base of the stem. Dicots usually have a more developed tap root system, where one main root grows deeper into the soil.

5. **Floral Parts**:
- The floral parts of monocots are usually in multiples of three (such as 3 or 6 petals), while dicots typically have floral parts in multiples of four or five (such as 4 or 5 petals).

### Summary of Differences

- **Venation**: Monocots (parallel), Dicots (reticulate)
- **Vascular Bundles**: Monocots (scattered), Dicots (circular)
- **Root System**: Monocots (fibrous), Dicots (tap root)
- **Floral Parts**: Monocots (multiples of 3), Dicots (multiples of 4 or 5)
