what are the differences between male and female gametes?
1201
gamete. 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.

Which statement is true about gametes? They are reproductive cells. fertilization.

For chromosome pairs 1-22, the autosomes, there is no difference between males and females. The Y chromosome carries a male-determining gene, SRY, which causes testes to develop. ... The X chromosome contains over 1000 genes, compared to 78 genes on the Y chromosome.

Gamete refers to a haploid sex cell that is a sperm in males and egg (oocyte) in females. Zygote is the diploid cell that results from the fertilization between an egg and a sperm. In mammals, the sperm (male gamete) fertilizes the egg (ovum, the female gamete) and the fertilized egg is called a zygote.

Terms in this set (2) Spermatogenesis takes place in the testes of males, oogenesis takes place in the ovary of the females. Spermatogenesis produces small, motile spermatozoa whereas in oogenesis the ovum is spherical, not motile and is much larger with more food reserves and cytoplasm.

Spermatogenesis and oogenesis are the processes of formation of male and female gametes. Spermatogenesis leads to the formation of sperms, whereas, oogenesis helps in the formation of ova. The fertilization of sperm and ova leads to the formation of a zygote which further develops into a embryo.

is that chromosome is (biology|cytology) a structure in the cell nucleus that contains dna, histone protein, and other structural proteins while gamete is (cytology) a reproductive cell (male (sperm) or female (egg)) that has only half the usual number of chromosomes.

Gametes are formed through a process of cell division called meiosis. This two-step division process produces four haploid daughter cells. Haploid cells contain only one set of chromosomes. When the haploid male and female gametes unite in a process called fertilization, they form what is called a zygote.

The male gametes of angiosperms consist of two sperm cells within a pollen grain or a pollen tube. They are derived from a single generative cell, which is formed as the smaller cell by unequal cell division in the microspore after meiosis.
1286039
Germ cells differentiate to produce male and female gametes, sperm and unfertilized eggs (oocytes or ova), and undergo meiosis to produce a haploid set of chromosomes. Haploid gametes then unite to form a diploid zygote that develops into a new individual.

In spermatogenesis, sperms release out from the testis whereas, in oogenesis, oocytes release from the ovary which develops later. Spermatogenesis results into four motile male gametes (sperms) from a Spermatogonium and oogenesis results into a single non-motile female gamete (ovum) from an Oogonium.

Spermatogenesis takes place in the testes of males, oogenesis takes place in the ovary of the females. Spermatogenesis produces small, motile spermatozoa whereas in oogenesis the ovum is spherical, not motile and is much larger with more food reserves and cytoplasm. ... It takes 70 days for sperm to be produced in males.

Gametes contain half the chromosomes contained in normal diploid cells of the body, which are also known as somatic cells. Haploid gametes are produced during meiosis, which is a type of cell division that reduces the number of chromosomes in a parent diploid cell by half.

Difference Between Spermatogenesis and Oogenesis. Spermatogenesis and oogenesis are the processes of formation of male and female gametes. Spermatogenesis leads to the formation of sperms, whereas, oogenesis helps in the formation of ova.

Unlike the body's other cells, the cells in the egg and sperm — called gametes or sex cells — possess only one chromosome. ... All of the gametes in the mother's eggs possess X chromosomes. The father's sperm contains about half X and half Y chromosomes. The sperm are the variable factor in determining the sex of the baby.

Sperm is the male reproductive cell, or gamete, in anisogamous forms of sexual reproduction (forms in which there is a larger, "female" reproductive cell and a smaller, "male" one). ... The human sperm cell is haploid, so that its 23 chromosomes can join the 23 chromosomes of the female egg to form a diploid cell.

The main difference between male and female gametophyte is that the microspore or pollen grain produces the male gametophyte while the megaspore produces the female gametophyte. Male and female gametophytes are the two gametophytic stages of heterosporous plants.
