Sex The gametes produced by an organism are determined by its sex: males produce male gametes (spermatozoa, or sperm, in animals; pollen in plants) while females produce female gametes (ova, or egg cells); individual organisms which produce both male and female gametes are termed hermaphroditic.rganisms of many species are specialized into male and female varieties, each known as a sex. Sexual reproduction involves the combining and mixing of genetic traits: specialized cells known as gametes combine to form offspring that inherit traits from each parent.

What Are the Functions of the Cytoplasm in the Egg Cell of Humans? What the Egg Needs. Sexual reproduction is the joining of two cells -- each from a different parent organism -- to create a new cell that can grow into a child organism. The child organism gets part of its DNA from each parent, resulting in a new combination of DNA that will control the development of the child.

Female Reproductive System Like the male reproductive system, a primary function of the female reproductive system is to make gametes, the specialized cells that contribute half of the total genetic material of a new person.he two uterine tubes, one from each ovary, provide pathways for the female gametes (eggs) to get from the ovaries to the uterus. The portion of the reproductive tract called the vagina is between the narrow uterine cervix and the outside of the body.

The Life Cycle of Plants The sperm cells within the pollen tube then vie to fertilize the egg. Once fertilization has occurred, the embryo develops within the female gametophyte, and the ovule becomes the seed, complete with a food source (the gametophyte tissue) and a seed coat (the integument).

- Each month, one of the two ovaries releases a mature egg during a process called ovulation (a sign of fertility). Both ovaries produce two types of hormones: estrogen and progesterone. These two hormones are necessary for female sexual maturation and reproductive processes. Egg (Ovum): Each ovum is created and stored inside the ovaries. Following ovulation, the egg is released by the ovaries and travels into the fallopian tubes. If the egg is to be fertilized by sperm, the fertilization usually must occur in the outer third of these tubes.

Reproductive System Reproduction — the process by which organisms make more organisms like themselves — is one of the things that set living things apart from nonliving matter. But even though the reproductive system is essential to keeping a species alive, unlike other body systems, it's not essential to keeping an individual alive. In the human reproductive process, two kinds of sex cells, or gametes (pronounced: GAH-meetz), are involved. The male gamete, or sperm, and the female gamete, the egg or ovum, meet in the female's reproductive system. The female needs a male to fertilize her egg, even though it is she who carries offspring through pregnancy and childbirth. When the sperm fertilizes, or meets, the egg, this fertilized egg is called the zygote.

ovum (ō`vəm) , in biology, specialized plant or animal sex cell, also called the egg, or egg cell. It is the female sex cell, or female gamete; the male gamete is the sperm spermor spermatozoon, in biology, the male gamete (sex cell), corresponding to the female ovum in organisms that reproduce sexually.he ovum of such an egg is a cell swollen with yolk material. The rest of the egg—e.g., the jelly mass surrounding amphibian eggs, and the shell, membranes, and egg white, or albumen, of bird eggs—is not cellular and is secreted around the ovum as it passes down the oviduct.

Human Reproduction Problem Set At ovulation, a mature egg is released from one of the ovaries into the body cavity. Before it has a chance of getting lost it is captured by one of the paired tubes called Fallopian tubes or oviducts. In the Fallopian tube, the egg is slowly propelled toward the uterus.

OBExam1Ch6 ANS: A. The head of the sperm contains the male chromosomes that will join the chromosomes of the ovum. The middle portion of the sperm supplies energy for the tail's whip-like action. If an X-bearing sperm fertilizes the ovum, the baby will be female. The tail of the sperm helps propel the sperm toward the ovum.

What are Sexually Transmitted Infections (STIs) or Diseases (STDs)? The Female Reproductive System. The female reproductive system provides several functions. The ovaries produce the female egg cells, called the ova or oocytes. The oocytes are then transported to the fallopian tube where fertilization by a sperm may occur. The fertilized egg then moves to the uterus, where the uterine lining has thickened in response to the normal hormones of the reproductive cycle. Once in the uterus the fertilized egg can implant into thickened uterine lining and continue to develop.

Courtship, Copulation, and Egg Creation Swifts and swallows mate in midair. After mating, inside the female, sperm swim up a tube called the oviduct, at the end of which there is an ovum, inside which resides the female sex germ. If the ovum is mature, it's already equipped with yolk, the yellow part of the future egg.

What is the function of an egg cell? The main function of egg cells is to join with male cells (sperm) for the purpose of reproduction. They also provide food for new cells that are made in the process. After a s…perm cell fertilizes an egg cell, it becomes a zygote. The zygote becomes an embryo, and the embryo becomes a fetus if we are discussing mammals.

REPRODUCTION Deep inside the woman, in her ovaries, one egg develops each month. From the man's testes, through his penis, millions of sperm enter the woman's vagina. Here, they begin their travel toward the egg. Only one sperm can enter an egg. When one does, fertilization occurs. Genetic material from the male and from the female combine, to create the first cell of an offspring. The fertilized egg migrates to the uterus where it develops into a fully formed fetus over a period of about 40 weeks. Then, a baby is born.

- Eggs carry the X chromosome whilst sperm cells carry either the X or the Y chromosome. If an egg cell is fertilised by a sperm carrying the X chromosome, the offspring will be female as it will have two X chromosomes in its cells. The offspring will be male if the sperm carries the Y chromosome. It is the sperm that decides the sex of the offspring.

meiosis One gamete comes from the female, and one comes from the male. Female gametes are also called eggs or ova. Female gametes are also called eggs or ova. They are created during the cellular reproduction process known as meiosis. The resulting gamete cell is a haploid cell. When the two haploid cells, the egg and sperm, fuse together during fertilization, the result is a diploid cell called a zygote. The zygote will mature into a new individual. The female gamete matures in the ovary and moves to the Fallopian tube.

Oogenesis: How the Female Reproductive System Produces Eggs The female gamete is called an ovum. The diploid germ cells that have the potential to develop into ova are called oogonia. In humans, all of a female's oogonia that she will make in her lifetime are created when she's still a fetus and hasn't even been born yet.
