Sperm differs from egg in having :-

Options

A. Power of motility
B. No stored food
C. More in numbers
D. All of the above

Answer

To answer the question "Sperm differs from egg in having:", we will analyze the characteristics of sperm and egg and compare them step by step.

### Step 1: Identify the characteristics of sperm
- Sperm are male gametes.
- They are haploid in nature, meaning they contain half the number of chromosomes.
- Sperm are flagellated, which means they have a tail that allows them to swim.
- They are produced in large quantities (millions) through a process called spermatogenesis.
- Sperm do not contain stored food; they lack mitochondria.

### Step 2: Identify the characteristics of egg
- Eggs are female gametes.
- They are also haploid in nature.
- Eggs are non-motile; they do not have the ability to move on their own.
- Typically, only one egg is released during each ovulation cycle.
- Eggs contain stored food in the form of yolk, which nourishes the developing embryo.

### Step 3: Compare the characteristics
- **Power of motility**: Sperm are motile due to their flagella, while eggs are non-motile.
- **Stored food**: Sperm lack stored food, while eggs have yolk to nourish the embryo.
- **Number**: Sperm are produced in large numbers (millions), whereas typically only one egg is released during ovulation.

### Step 4: Conclusion
Based on the comparisons:
- Sperm differ from eggs in having:
- Power of motility (sperm can swim, eggs cannot)
- No stored food (sperm lack yolk, eggs have it)
- More in numbers (sperm are produced in millions, eggs are produced one at a time)

Thus, the correct answer is **D) All of the above**.
