Most of the minerals enter into the cytoplasm of epidermal cells of root by (A)_____ while some ions move (B)____ into the epidermal cells.

Answer

To solve the question, we need to identify the methods by which minerals enter the epidermal cells of the root. The question has two parts:

(A) Most of the minerals enter into the cytoplasm of epidermal cells of the root by (A) _____ while some ions move (B) _____ into the epidermal cells.

### Step-by-Step Solution:

1. **Understanding Mineral Absorption**:
- Minerals in the soil exist as charged particles (cations and anions) and cannot passively diffuse across the cell membrane due to their charge.
- The concentration of minerals in the soil is generally lower than that inside the epidermal cells, which means that minerals must be moved against a concentration gradient.

2. **Identifying Method A**:
- Since minerals need to be moved against their concentration gradient, this process requires energy. The primary method for this is **active transport**.
- Therefore, for part (A), the answer is **active absorption**.

3. **Identifying Method B**:
- Some ions can move into the epidermal cells without the need for energy, which occurs when they move along their concentration gradient. This process is known as **passive transport** or **facilitated diffusion**.
- Thus, for part (B), the answer is **passive absorption**.

### Final Answers:
(A) active absorption
(B) passive absorption
