4 differences between sperm and ovum

Sperm are extremely small - hundreds of millions of them swim around in a teaspoon of ejaculate, and even then form less than 1% of the total. A human ovum can just be seen, as a speck, with the unaided eye.

Sperm move on their own, ova don't.

Women release one ovum per menstrual period, except in unusual cases (fraternal twins or multiples). Men release hundreds of millions of sperm per ejaculation, and can repeat that several times per week.

Sperm cells are manufactured continuously throughout a man's life, starting at puberty. Women are born with all the ova they'll ever have

Oviparous animals undergo external fertilisation, while viviparous animals undergo internal fertilisation.The zygoteundergoes rapid division after fertilisation and moves down the oviduct. During this period, many protective layers form as a hard shell around the developing embryo.The chick hatches from the egg after three weeks.There are three distinct stages in the life cycle of a frog - egg, tadpole and adult.In the first stage, the egg fuses with a sperm to form a zygote. The zygote further divides to form an early tadpole, which matures into a late tadpole.During metamorphosis, the larvatransforms into an adult frog.Our bodies undergo certain changes as we develop from childhood to adolescence stage.

sperm is the male reproductive gamete 

where ovum is the female reproductive gamete

okay!!!!!

  • -8

SPERMS:-

1)It is the male reproductive gamete.

2)It does not stores food.

3)It is smaller in size.

4)millions of sperms are released at a time.

 

OVA:-
1)it is the female reproductive gamete.

2)It stores food.

3)It is bigger in size.

4)Only one ova is released in a month.

sperm is produced in testis whereas ovum is produced in ovary.

sperm production starts at puberty ,and production of ova starts at embryo.

SPERMS
  • ​Has a tail for locomotion
  • Male gamete cell 
  • Can carry two types of chromosomes "X" & "Y"
  • Can be released more than twice a week
  • Can survive in the womb for 3 - 5 days
  • A male can produce sperms from the onset of puberty till death
  • microscopic in nature a million  can be found in a teaspoon of ejaculate 

OVA
  • Oval in shape dose not move on its own 
  • Female gamete cell
  • Can carry only one type of chromosomes "X"
  • Released only once in a single month 
  • Can survive in the fallopian tube for 12 - 24 hrs
  • Females are born with all the ova they will ever produce
  •  Biggest of all cells in the human body can be seen with the naked  eye

Ovum

Sperm

Definition

Ovum is the gamete that is produced in the ovary of a female.

Sperm is the gamete that is produced in the testis of a male.

Anatomy

Ovum has a nucleus that is surrounded by cytoplasm, which is guarded by the zona pellucid and the follicular cells.

A sperm cell consists of a head, a mid-piece and a tail. The head contains the nucleus with densely coiled chromatin fibers, surrounded anteriorly by an acrosome, which contains enzymes used for penetrating the female egg. The mid-piece has a central filamentous core with many mitochondria spiraled around it, used for ATP production for the journey through the female cervix, uterus and uterine tubes. The tail or "flagellum" executes the lashing movements that propel the spermatocyte.

Produced in

Ovum is produced in the ovary of a female human being.

Sperm is produced in the testicles of a male human being.

Size

Larger compared to sperm cells. Approximately 0.15 to 0.2mm in size.

It is very small in size compared to ovum. It is also considered as the smallest cell in the body.

Appearance

The ovum is one of the largest human cells in the body. It is round in shape and has the largest volume in relation to the surface. The cell consists of a large amount of cytoplasm in which the nucleus dissolves until just before conception.

The sperm has an oval head on the top and has a rigid middle with a slimly tail in the back to allow it to swim. It is straight in shape.

Shape

Round, oval or a circle.

Straight.

Produce in numbers

Only a single ovum is produced during once menstruation cycle.

Millions of cells are released during a single ejaculation.

Temperature

Requires warm body temperature for sustenance.

Requires approximately two degrees lesser than the body temperature for sustenance.

Time of formation

Ova are usually formed in a female before birth.

Sperm cells form during puberty.

Life-span

Ovum has a short life span. If an egg cell is not fertilized 12 to 24 hours after its release from the ovary, it will dissolve.

Sperm cells have a longer life span. Once ejaculated in the female womb they can survive for 3-5 days.

Production till

Ovum form before birth and are active only till menopause.

Sperm cells start being produced from the body from puberty till death.

Storability

Cannot be stored.

Can be frozen and stored.

Metabolism

Active.

Less active.

Mobility

Ovum contains cytoplasm, which allows them to be active internally. After the nucleus is released from the follicular cell, it becomes less mobile.

Sperm are active and externally mobile. They use their tails to swim against the stream of fluid in the oviduct to the fallopian tube.

Sperm cell is the male reproductive cell and is derived from the Greek word sperma mean seed sperm cell cannot be divided and have a limited life span but after fusion with egg cells during fertilization a new organisms begin developing start as a totipotent zygote

Sperm is locomotive while ovum is not locomotive . Sperms are produced in millions but ovums are only produced once in 28-30 days. Sperms are produced by testis in males, and ovums are produced by ovaries in males. Ovums contain only X chromosomes while sperms have both X and Y chromosomes.

BASIS FOR COMPARISON HUMAN SPERM HUMAN OVUM
Meaning The male gamete which is long, motile, flagellated cell and is differentiated into head, neck, middle piece and tail is known as sperm. The female gamete, where the cells are rounded spheres and non-motile, though not differentiated into different regions are known as 
Ovum.
Size Very small. Large in size.
Movement Can move. Not able to move.
Mitochondria In the middle piece, mitochondria form a spiral and are compactly arranged. Mitochondria are scattered in the cytoplasm.
Cytoplasm Present in the small amount. Present in large amount.
Nucleus It is condensed with no nucleoplasm. Ovum contains nucleoplasm, called as the germinal vesicle.
The nucleus contains X or Y chromosome. The nucleus contains only X chromosome.
Centrioles Present. Absent.
Produced in Sperms are produced in the testes. Ovum is produced in ovaries.
Number of sperms formed Four sperms are formed from one spermatogonium. Only one ovum is formed from one oogonium.
Differentiated into Sperms are separated into head, neck, middle piece and tail. Ovum is not externally separated into regions.
Surrounded by Surrounded by plasma membrane only. Ovum is surrounded by the egg envelopes.

Internal fertilization External fertilization
Fertilization occurs inside the female's body Fertilization occurs outside the female's body
Sperms are ejaculated in the form of fluid in female's body which then combines with egg. The male releases sperm cells onto the eggs which are laid external to the female's body.
Mostly occurs in terrestrial animals and humans Mostly occurs in amphibians and aquatic animals.
The number of sperms and eggs produced is comparatively less The number of sperms and eggs produced is more in comparison to internal fertilization.
Example: Human beings, Birds
Example: Fishes, Frogs
