Developmental Biology – Sea Urchin Fertilization
Quick Q&A for NEET | CSIR NET | MSc Entrance Prep
🎥 Full video coming next week on Ride Education!
Q1. How does sea urchin sperm reach the egg?
Answer:Sea urchin eggs release a chemoattractant called resact from their jelly coat, which guides the sperm toward the egg.
Q2. What is the role of bindin in the acrosome reaction?
Answer:Bindin is a protein on the sperm’s acrosomal process. It binds specifically to receptors on the egg’s vitelline membrane, ensuring species-specific recognition and fusion.
Q3. How do sea urchins prevent polyspermy?
Answer:They use two blocks:
Fast block: A quick change in membrane potential creates an electrical barrier.
Slow block: A cortical reaction leads to formation of a fertilization membrane that physically prevents additional sperm entry.
✨ Stay tuned and follow Ridh Education for detailed explanation in our upcoming video!

Determinate vs. Indeterminate Development** – Here are two important types of embryonic development!
What is Determinate Development?
Also known as **mosaic development**, this is a type of development where the fate of embryonic cells is **pre-determined** from a very early stage.
If you remove any of the early blastomeres (cells), the embryo **cannot** develop into a complete organism.
🧠 **Key Features:**
- Each blastomere has a **fixed developmental fate**.
- Removal of a blastomere at an early stage results in **incomplete development** of the organism.
🔬 **Example:**
**Arthropods** (like insects) and **Mollusks** (like snails) show determinate cleavage.
### 🔷 **What is Indeterminate Development?**
Also known as **regulative development**, this is a type of development where the fate of early embryonic cells is **not fixed**.
Even if an early blastomere is removed, it can still develop into a **complete organism**.
🧠 **Key Features:**
- The fate of blastomeres is **flexible**.
- A single blastomere can give rise to a **fully functional embryo**.
🔬 **Example:**
Mostly seen in **deuterostomes** like **echinoderms** (e.g., starfish) and **chordates** (e.g., humans).
---
🧪 **Fun Fact:**
Indeterminate development is the reason why **identical twins** can form from a single fertilized egg!
