What is the vocabulary term for egg and sperm cells?
Gametes are an organism’s reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome.
What produce both sperm and eggs are called?
Animals in which both sperm and eggs are produced by the same individual (hermaphroditism) are termed monoecious. In dioecious species, the sexes are separate.
What is the oocyte?
: an egg before maturation : a female gametocyte.
What gamete means?
gamete, sex, or reproductive, cell containing only one set of dissimilar chromosomes, or half the genetic material necessary to form a complete organism (i.e., haploid). …
What does the term Gametogenesis mean?
gametogenesis, in embryology, the process by which gametes, or germ cells, are produced in an organism. The formation of egg cells, or ova, is technically called oogenesis, and the formation of sperm cells, or spermatozoa, is called spermatogenesis.
What is theca cell?
Theca cells are the endocrine cells associated with ovarian follicles that play an essential role in fertility by producing the androgen substrate required for ovarian estrogen biosynthesis. Theca cells differentiate from the interfollicular stroma in response to proteins secreted from growing follicles.
What is Oocytogenesis?
(ō′ə-jĕn′ĭ-sĭs) The formation, development, and maturation of an ovum.

What does the term Gametophyte mean?
alternation of generations
gametophyte, in plants and certain algae, the sexual phase (or an individual representing the phase) in the alternation of generations—a phenomenon in which two distinct phases occur in the life history of the organism, each phase producing the other. The nonsexual phase is the sporophyte.
What are Homogametes or Isogametes?
Homogametes are also known as isogametes. Homogametes are similar in morphological appearance and male and female gametes can’t be distinguished. For example, in Rhizopus. Heterogametes are the gametes that are morphologically dissimilar and thus, male and female gametes can be distinguished.
What is the sperm cell?
sperm, also called spermatozoon, plural spermatozoa, male reproductive cell, produced by most animals. The sperm unites with (fertilizes) an ovum (egg) of the female to produce a new offspring. Mature sperm have two distinguishable parts, a head and a tail.
How does sperm meet egg?
When Sperm Meets Egg. Touching this layer also makes the sperm release its protein-destroying enzymes, which it stores in a vesicle called the acrosome near the front of its head. These enzymes pave the way for the sperm to penetrate the egg membrane and release its genetic material inside.
Which is bigger egg or sperm?
Egg cells are considerably larger than sperm cells because they carry the cytoplasm and organelles necessary for cell division and growth to begin, while sperm cells are basically a cell nucleus and a tail.
How do sperm and egg cells differ?
HOW ARE EGGS AND SPERM DIFFERENT. Eggs are produced by the ovaries and sperms are produced by testis. The size of the egg cell is larger than the sperm cell. The sperm contains a tail for locomotion whereas egg (ovum) is stable structure.
Where do sperm and egg cells meet?
The setting. Egg and sperm travel in opposite directions to meet in (most often) the fallopian tubes. During ovulation, ovaries release an egg into one of the fallopian tubes, and the egg proceeds down the tube toward the uterus, which is being prepared for possible implantation.
