Dispersal of seed by water and explosion activity - Free Printable

To solve the problem, we need to analyze the features of each seed and determine the mode of dispersal (Water or Explosion). Let's go through each seed step by step:

1. Lotus

- Features: Lotus seeds are small, hard, and enclosed in a pod that floats on water. They are adapted to survive in aquatic environments.
- Mode of Dispersal: Water
- Explanation: Lotus seeds are dispersed by water because they are contained within pods that float on water surfaces. This allows them to be carried by currents to new locations where they can germinate.

2. Coconut

- Features: Coconut seeds are large, surrounded by a thick, fibrous husk that makes them buoyant. The statement "This seed floats" confirms its ability to float on water.
- Mode of Dispersal: Water
- Explanation: Coconuts are well-known for their ability to float on water. This adaptation allows them to be carried by ocean currents to distant shores, where they can germinate and grow into new coconut trees.

3. Bean

- Features: Bean seeds are enclosed in a pod that splits open when mature. The force of the pod splitting helps disperse the seeds.
- Mode of Dispersal: Explosion
- Explanation: Bean pods undergo a process called dehiscence, where the pod dries out and splits open with enough force to eject the seeds. This is a form of mechanical dispersal known as explosion.

4. Poppy Seed

- Features: Poppy seeds are small and lightweight, often attached to a structure that can catch wind or be carried by animals.
- Mode of Dispersal: Wind (Note: Although not explicitly mentioned in the options, wind is a common mode of dispersal for poppy seeds)
- Explanation: Poppies have a unique dispersal mechanism where the seeds are released from a capsule and can be carried by wind. However, since the options provided are limited to "Water" and "Explosion," we should consider the closest match. In this case, the seeds do not fit the "Explosion" category, so we might infer it doesn't fit either option perfectly, but typically, wind would be the correct answer if available.

Final Answer:

\[
\begin{array}{|c|c|c|}
\hline
\text{Name of the seed} & \text{Features} & \text{Types of seed dispersal} \\
\hline
\text{Lotus} & \text{Small, hard, enclosed in a floating pod} & \text{Water} \\
\hline
\text{Coconut} & \text{Large, buoyant, floats on water} & \text{Water} \\
\hline
\text{Bean} & \text{Enclosed in a pod that splits open} & \text{Explosion} \\
\hline
\text{Poppy seed} & \text{Small, lightweight, released from a capsule} & \text{(Not fitting exactly, but closest to none of the given options)} \\
\hline
\end{array}
\]

Since the question only provides "Water" and "Explosion" as options, and considering the typical dispersal mechanisms, the best answers based on the given options are:

\[
\boxed{
\begin{array}{|c|c|c|}
\hline
\text{Name of the seed} & \text{Features} & \text{Types of seed dispersal} \\
\hline
\text{Lotus} & \text{Small, hard, enclosed in a floating pod} & \text{Water} \\
\hline
\text{Coconut} & \text{Large, buoyant, floats on water} & \text{Water} \\
\hline
\text{Bean} & \text{Enclosed in a pod that splits open} & \text{Explosion} \\
\hline
\text{Poppy seed} & \text{Small, lightweight, released from a capsule} & \text{None (but closest to none of the given options)} \\
\hline
\end{array}
}
