Animals which see well during night have abundant

Options

A. Rods
B. Cones
C. Scotopic cells
D. Night vision cells

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about animals that have good night vision and what type of cells are abundant in their eyes.

2. **Identifying the Types of Photoreceptor Cells**: There are two main types of photoreceptor cells in the eyes: rods and cones.

3. **Eliminating Incorrect Options**:
- **Cones**: These cells are primarily responsible for color vision and function best in bright light conditions. Therefore, they are not abundant in animals that see well at night.
- **Scotopic Cells**: This term is not commonly used in biological terminology regarding photoreceptors, so it can be eliminated.
- **Night Vision Cells**: This is a vague term and not a recognized category in the context of photoreceptors, so it can also be eliminated.

4. **Focusing on Rods**:
- **Rods**: These cells are highly sensitive to light and allow for vision in low-light conditions (scotopic vision). They contain a pigment called rhodopsin, which is crucial for night vision.

5. **Conclusion**: Since rods are the cells that enable night vision, the correct answer to the question is that animals which see well during the night have an abundance of **rods**.

**Final Answer**: The correct option is **Rods**.
