Read the following statement
All ctenophores have solid tentacles which possess lasso cell without exception State true or false

Answer

To determine whether the statement "All ctenophores have solid tentacles which possess lasso cells without exception" is true or false, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Ctenophores**: Ctenophores, commonly known as comb jellies, are a group of marine invertebrates belonging to the phylum Ctenophora. They are characterized by their gelatinous bodies and are known for their unique method of locomotion using cilia.

2. **Examine Tentacle Structure**: The statement mentions that all ctenophores have "solid tentacles." It is important to note that ctenophores do have tentacles, but they are not solid in the traditional sense. Instead, they are typically composed of a gelatinous substance and can vary in structure.

3. **Identify Lasso Cells**: The statement also refers to "lasso cells." Ctenophores possess specialized cells called "colloblasts," which are adhesive cells used for capturing prey. The term "lasso cells" might be a misinterpretation, as the more commonly used term is "colloblasts."

4. **Assess the Statement**: The assertion that all ctenophores possess solid tentacles and lasso cells is not entirely accurate. While they do have tentacles and specialized cells for capturing prey, the description of the tentacles as "solid" and the use of "lasso cells" is misleading.

5. **Conclusion**: Based on the analysis, the statement is **false**. Not all ctenophores have solid tentacles, and the terminology used for their specialized cells is not correct.

### Final Answer:
**False**
