B. A - dinoflagellates , B - saprotrophs, C - cell wall , D-calcium.
C. A - dinoflagellates , B - heterotrophs , C - cell membrane , D - phosphorous
D. A - golden algae, B- photosynthetic , C - cell wall, D - silica

Answer

To solve the question step by step, we will fill in the blanks based on the information provided in the video transcript.

### Step 1: Identify what chrysophytes are known as
- The first blank (A) asks what chrysophytes are also known as. According to the transcript, chrysophytes are referred to as **golden algae**.

### Step 2: Determine the nutritional mode of most members of this group
- The second blank (B) inquires about the nature of most members of this group. The transcript indicates that most members of chrysophytes are **photosynthetic autotrophs**. Thus, we can fill in this blank with **autotrophs** or **photosynthetic**.

### Step 3: Understand the structure of diatoms
- The third blank (C) asks about the arrangement of diatoms. The transcript mentions that diatoms have a soap-box-like arrangement of their **cell wall**. Therefore, we will fill in this blank with **cell wall**.

### Step 4: Identify the material deposited in diatoms
- The fourth blank (D) asks about what is deposited in the diatoms. The transcript states that there is a deposition of **silica** in the cell wall of diatoms. Hence, we fill this blank with **silica**.

### Final Answers:
- A: golden alga
- B: photosynthetic (or autotroph)
- C: cell wall
- D: silica

### Summary of the Answer:
The chrysophytes are also known as **golden alga**. Most of the members of this group are **photosynthetic**. The diatoms have a soap-box-like arrangement of **cell wall** in which there is deposition of **silica**.
