In dicot embryo hypophysis is

Options

A. Termical cell of suspensor that grows to push the embryo downwards
B. Middle cell of suspensor that grows to push the embryo downwards
C. Last cell of suspensor that forms radicle
D. Part of embryo that gives rise to radicle.

Answer

To answer the question "In dicot embryo, hypophysis is...", we need to understand the structure of a dicot embryo and the role of the hypophysis within it. Here’s a step-by-step solution:

### Step 1: Understand the Structure of a Dicot Embryo
A dicot embryo typically consists of two main parts: the cotyledons (the seed leaves) and the embryonic axis. The embryonic axis includes the hypocotyl and the radicle.

**Hint:** Remember that dicot embryos have two cotyledons, which is a distinguishing feature.

### Step 2: Identify the Suspensor
The suspensor is a structure that connects the embryo to the surrounding tissue of the seed. It provides nutrients to the developing embryo and helps anchor it.

**Hint:** The suspensor is crucial for the embryo's growth and development, as it helps push the embryo into the nutrient-rich endosperm.

### Step 3: Define the Hypophysis
The hypophysis is a specific part of the suspensor. It is the last cell of the suspensor and plays a crucial role in the development of the embryo.

**Hint:** Focus on the position of the hypophysis; it is located at the terminal end of the suspensor.

### Step 4: Role of the Hypophysis
The hypophysis is responsible for forming the radical, which is the part of the embryo that will develop into the root of the plant.

**Hint:** The radical is essential for anchoring the plant and absorbing water and nutrients from the soil.

### Conclusion
In summary, the hypophysis in a dicot embryo is defined as the last cell of the suspensor that forms the radical.

### Final Answer
The hypophysis is the last cell of the suspensor that forms the radical.
