Definition

1. Noun:
   • Zygote: In biology, a hợp tử is the cell formed by the union of two gametes (e.g., a sperm and an egg). It is the initial stage of a new organism's development, containing a complete set of chromosomes.

Usage Examples

• Noun:
  • Sau khi thụ tinh, trứng và tinh trùng kết hợp tạo thành một hợp tử. (After fertilization, the egg and sperm combine to form a zygote.)
  • Hợp tử sẽ phân chia nhiều lần để phát triển thành phôi. (The zygote will divide many times to develop into an embryo.)

Advanced Usage

• Hợp tử lưỡng bội (diploid zygote): A zygote containing two complete sets of chromosomes, one from each parent.
  • Hợp tử lưỡng bội của người có 46 nhiễm sắc thể. (A human diploid zygote has 46 chromosomes.)

Variants and Related Words

• Phôi (embryo): The developmental stage following the zygote.
• Bào tử (spore): A reproductive cell in plants, fungi, and some algae, which is not formed by the fusion of gametes and is therefore distinct from a zygote.
• Hợp bào (syncytium): A multinucleated cell, which is a different biological structure from a single-celled zygote.

Synonyms

• Trứng đã thụ tinh (fertilized egg): This phrase is often used interchangeably with hợp tử in general contexts, though hợp tử is the precise scientific term.

Related Phrases / Compound Terms

• Sự hình thành hợp tử (zygote formation): The process leading to the creation of a zygote.
• Giai đoạn hợp tử (zygote stage): The very early period of development.
