Mention any two characteristics of pollen grains of plants such as maize and cannabis.

Explanation

**Step-by-Step Text Solution:**

1. **Understanding the Context**: The question asks for characteristics of pollen grains specifically from plants like maize and cannabis, which are known to be pollinated by wind (anemophily).

2. **Characteristic 1 - Large Numbers**: One significant characteristic of pollen grains in maize and cannabis is that they are produced in very large quantities. This adaptation is crucial because it helps to ensure that enough pollen grains reach the female reproductive structures despite the loss of many gametes during the transfer process.

3. **Characteristic 2 - Light and Non-Sticky**: Another important characteristic is that the pollen grains are very light and non-sticky. Being light allows them to be easily carried by air currents, facilitating their movement from one plant to another. The non-sticky nature ensures that they do not adhere to surfaces other than the feathery stigma of the female flowers, which is essential for successful fertilization.
