Male and Female reproduction Flashcards
1
Q
Functions
Female reproduction
A
- Egg production
- Receive and store sperm
2
Q
Components
Female reproduction
A
- Ovary: female reproductive glands
- Ovarioles: Basic unit of egg production
- Lateral oviducts: Receive mature oocytes (eggs) from ovarioles
- Common oviduct: Intersection of lateral oviducts
- Gonopore: Connects common oviduct to genital chamber
- Vagina (genital chamber): Receives male genitalia during copulation
- Vulva (ovipore): External opening of the vagina
3
Q
Egg production
A
- Occurs in the ovarioles which contains eggs in progressive stages of maturation
- Number of ovarioles varies depending on the taxon, its size, and lifestyle
4
Q
Spermatheca
A
Receives and stores sperm
5
Q
Spermathecal gland
A
Provides nourishment for stored spermatozoa
6
Q
Fertilization
female reproduction
A
- Female controls liberation of sperm – synchronous with egg movement in oviduct
- Sperm enters egg through the micropyle (openings in the eggshell)
7
Q
Accessory gland functions
Female reproduction
A
- Secrete material to glue or cement eggs to the substrate
- Secrete protective coating on the eggs (egg capsule, ootheca, etc.)
- Secrete silken stalk in lacewing
- Act as poison gland in many Hymenoptera
8
Q
Functions
Male reproduction
A
- Production and storage of spermatozoa
- Transport of spermatozoa to the reproductive tract of the female
9
Q
Components
Male reproduction
A
- Testes: male reproductive gland
- Sperm tubes: Basic unit of sperm production
- Vas deferens: Expands to form seminal vesicles, join to form ejaculatory duct
- Seminal vesicles: Sperm storage organ
- Ejaculatory ducts: Transport sperm to gonopore
- Gonopore: Transports sperm to aedeagus
- Aedeagus: male copulatory organ
10
Q
Sperm production
A
Produced in the sperm tubes in progressive stages of maturation
11
Q
Accessory glands functions
Male reproduction
A
- Seminal fluid: Nourish and serve as carrier/activator of spermatozoa
- Female behaviour: egg prod. & oviposition, decrease receptivity to other males
- Mating plug: Prevents loss of sperm and further mating
- Spermatophore: A special structure enclosing sperm in some insects
