free skip

:)
lol
WORK HARDER, U DOING GREAT ❤❤✨

9

life span of sequoia/redwood

3000-4000

10

parrot and crow life span

140, 15

11

mango life span

200 yrs

12

factors for reproduction

habitat, physiology, genetic makeup

13

simple binary fission eg

ameoba

14

logitudinal binary fission

euglena, verticula

15

transverse binary fission

planaria, paramoecium, bacteria, diatoms

16

exogenous budding

marine: , hydra, obelia (1-zooids)

17

endogenous budding

marine AND freshwater
spongila
has gemule

18

plasmotomy

plasmotomy A type of asexual reproduction in which a multinucleate protozoan cell divides into two or more multinucleate daughter-cells without the occurrence of mitosis.
eg: Plasmodium and Opalina.

19

oblique binary fission

cerateum, gunyaulax

20

veritcula
paramoecium shape

bell animal cell, slipper animal cell

21

Spores: order only

1 zoospore
2 conidia
3 sporangiospore
3 chalmadospore
5 onida
5 gemule

22

ZOOSPORE

Motile
endogenous
flagellated
ALGAE
CHLAYMYDOMONAS: Pyramid shape, antheriorly flagellated
4 or 8 daughter cells

23

CONIDIA SPORES

Non motile
exogenous
conidioPHORES produce this
FUNGI
Penicillium

24

Sterigmata

Flaskshaped in condia spores which contain chain of conidia

25

sporangiosopre

Non motile, endospore
mucor

26

Oinida

Agarcus
thin, small walled

27

chalmadosopres

Rhizopus
non motile, thick wall

28

gemule

endogenous bud
sponges

29

2 types of regeneration

epimorphosis (replacement) and morphallaxis(small part)

30

bud

compact immature shoot protected by immature leaf

31

rhizome

ginger

32

bulb

garlic onion

33

offset

eichhornia (water hyacinth) pistia (water lettuce)

34

suckers

Chrysanthemum, pineapple

35

aerial shoot

sugarcane, optunia

36

bulbis

oxalis, anans, lily, dioscorea, agave

37

leaves veg prop eg

adiantum (walking fern) begonia, kalanchoe

38

roots eg

dahila

39

in bryophylum what arises from leaf notched

adventitious leafs/ leaf buds

40

Veg rep of corm eg

Crocus

41

veg rep of stolon

vallisneria

42

neelakuranji

strobilanthus kunthiana
12 yrs

43

certain bamboo

perineal but monocarpic
50 to 100 yrs
bambusa tulda, melocanna bambusoides

44

life span of doG
laboratory mouse

20 , 4.5

45

max human life span

121
japan, izumi shirechiyo
pneumonia, 121 yrs 237 days

46

Asexual reproduction aka

Agamogenesis agamogeny somatogenic

47

Transfers binary fission in paramecium

Amiotic division in meganucleus, mitotic div in micronucleus
They div to form 2 dissipate daughter cell 1 proter (anterior) opisthe (posterior)

48

What is totipotent in budding reproduction

Archeocytes presents in gemule

49

Live expectancy is based on

AVG life span and population

50

rep in cocoroach

2 testes in 4th to 6th abdominal terga
female has 2 ovaries on either side in 2th to 6th abdominal sgmentts, each contain 8 ovule
formation of 3 layered spermatophore is transfereed to female chamber by male phallomeres

51

Earthworm rep

2 pair of testes in segment 10 and 11
2 pair of seminal vesicles (in seg 11 and 12)
1 pair of ovary in segment 13
male matuures first, so cross fertilization

52

sex pheromones of moths silkworm

Bombyx mori
female produce distinctive alchohol (bombykol) to male

53

PARTHENOGENESIS

if syngamy dosent occur and female dev into a new induvidual without veing fertilized by a male gamete
haplid

54

parthenognesus type

arrhenotoky : MALE: bee, wasp, turky
thelytoy: FEM: lacerta, (sexycola america), typhina brahmina, rotifers, whiptail lizard
Amphitoky: BI: Aphis

55

Bisexual orgs aka and eg

HERMAPHRODITE
earthworm
spones
tapeworm
leech

56

drones of apis is

fertile male

57

monoesterous animals have

1 breeding season in a year
wolf, bear, fox

58

estrous cycle means

breeding period

59

cleidoic egg

normal egg
internal fertilization. external dev
