What is the process of combining male and female sex cells called?

Step 1: Analyze the diagram. The diagram illustrates a process where a "Male Sex Cell" and a "Female Sex Cell" undergo a "combining" step. This combined entity then goes through "Growing" to form a "Seed". Step 2: Understand the question. The question asks for the specific biological term for the "process of combining male and female sex cells". Step 3: Evaluate the given options. • A. Pollination: This is the transfer of pollen from the anther to the stigma in flowering plants. It is a step that precedes the combination of sex cells but is not the combination itself. • B. Fertilisation: This is the fusion of male and female gametes (sex cells) to form a zygote. This directly matches the "combining" step shown in the diagram and is the process that leads to the development of a seed. • C. Photosynthesis: This is the process by which plants convert light energy into chemical energy (food). It is unrelated to reproduction. • D. Transferring: This is a general term for moving something from one place to another. While sex cells might be transferred, it is not the specific biological term for their fusion. Step 4: Conclude the correct answer. The process of combining male and female sex cells is called fertilisation. The final answer is B 3 done, 2 left today. You're making progress.
