### cell | gamete | ovum | egg:

Raw egg
* are a common source of salmonella
  - used in homemade versions of mayonnaise and hollandaise sauce
* can be a source of salmonella
  - dangerous for the young children and elderly
  - carry dangerous amounts of salmonella
* can contain bacteria that, if consumed, can cause salmonella infection
  - harmful bacteria that if consumed can cause salmonella infection
* can contain salmonella and other bacteria
  - result in a problem when used in homemade ice cream and salads

Spawn
* includes cell membranes
  - chromosomes
  - corpi
  - cytoskeletons
  - lobes
  - nuclei
  - plasma membranes
  - sections
  - vacuoles
  - yolks
* is an egg
  - eggs

Squid egg
* Some squid eggs are free-floating, others are attached to seaweed or to the ocean floor.
* develop faster in warmer temperatures, resulting in higher hatch rates.

Unfertilized egg
* are hemizygous and develop into haploid males
  - identifiable under the microscope by their elongated shape
  - laid in much spacious drone cells where they develop into drones
* become drones, while fertilized eggs become either workers or queens
  - male, and thus remain haploid
* develop into monoploid offsprings that develops into males
  - winged male fire ants
* go through cleavage divisions, sometimes to blastula.
* produce male larvae.

Unhatched egg
* are an easy target for humans and small mammals along nesting sites.
* can break, and nestlings can die, and rot or attract pests.
* have a dark area within the shell while hatched eggs are transparent.

### cell | gamete:

Sperm
* All sperm require some form of liquid to swim to the eggs
  - sperms have a head and a tail called a flagellum
* Any sperm can fuse with any egg.
* Every sperm has a soul.
* Many sperm continue up to the ovary and can fertilize the egg
  - surround the egg in the Fallopian tube
* Most sperm have a group of five mitochondrial clumps in the midpiece.
* Some sperm is part of anglerfish
  - argentines
  - belugas
  - bluefishes
  - carps
  - cods
  - coelacanths
  - coneys
  - congers
  - flounder
  - frogfishs
  - gars
  - gobies
  - goldfishes
  - guppies
  - hammerheads

  - plaices
  - rays
  - remoras
  - semen
  - sharks
  - smallmouths
  - snooks
  - stingrays
  - stonefishs
  - triggerfish
* are formed in the testis, a part of male reproductive system
  - produced by primary sex organ i.e., called testes
* are produced in seminiferous tubules present in male reproductive organ testis
  - the testis situated inside the scrotum
  - single celled male gametes with a head, midpiece, and a tail
  - the male gametes
* arise from transformation of choanocytes.
* contribute only nuclear DNA when the egg is fertilized.
* feed on nutrients in the semen fluid.
* have flagella.
* includes acrosomes
  - corpi
  - lobes
* move to ovum and fuse with it to form a zygote.
* originate in the testes and leave the male body through the penis.
* produced in males are deposited into vagina through the process called copulation.
* swim with their tails.
* tastes like sea water mixed with egg white.

### cell | gamete | sperm:

Human sperm
* are much smaller than a human egg.
* comes in three varieties, mixed.
* have a single flagellum.
* is made in the testicles of a man.
+ Sperm, In humans: Biological reproduction :: Human sexuality
  * Human sperm is made in the testicles of a man. Human sperm contains 23 chromosomes. A human needs 46 chromosomes, so a sperm cell is called a 'haploid' as it only has half. The other half is contained within the ovum or egg of a female. During sex, semen is shot out of the man's penis during ejaculation.

Male sperm
* are generally faster swimmers than female sperm.
* is stored within the female for use throughout the entire breeding season.
