Adhesion of stamen

Answer 13

Free stamen- polyandrous
1 bundle: monoadelophous, China Rose
2 bundle: diadepholus, pea
More: polyandrous, Citrus

Answer 14

Female
Free calpel, lotus, rose- Apocarpous
Fused carpel- mustard, tomato- synchronous

Question 15

Ovary

Answer 15

Basal, swollen
Chamber of ovaries- Loculi
1 C- unilocular
2- bi
3-tri
Ovules are borne in these chambers

Question 16

Placentra

Answer 16

Marginal
Axile
Parietal
Free central
Basal

Question 17

Marginal

Answer 17

ridge along vertical suture of ovary
Ovules are borne in 2 alternate rows
Pea

Question 18

Axile

Answer 18

Axile position, ovules are located in multilocular ovary

China Rose, tomata, lemon

Question 19

Parietal

Answer 19

One chamber ovary becomes 2 chamber due to false septum
Ovule develop on innerwall on peripheral
MUSTARD, ARGEMONE

Question 20

Free central

Answer 20

Ovules are borne on central axis, septa absent in ovary

PRIMROSE, DIANTHUS

Question 21

Basal

Answer 21

The placenta develops at base, single ovule in placenta

SUNFLOWER, MARIGOLD

Question 22

Parthenocarpic fruit

Answer 22

Fruits without fertilisation

Banana

Question 23

Part of fruit

Answer 23

Fruit wall: pericarp develops from walls of ovary
Dry or fleshy
If fleshy:
Epicarp outer
Mesocrap middle
Endocarp innermost

Seeds develop from ovules:
Grapes,banana
In apple, pear fruit formation with other part

Question 24

Simple fruit
Aggregate fruit
Multiple fruit

Answer 24

Syncarpous ovary,
Dry fruit, succulent
Polycarpellary, Apocarpous: Strawberry, RaSbErry
Entire inflorescence, JACKFRUIT, mulberry, pineapple, Ficus

Question 25

Dry fruit

Answer 25

Dehiscent: Legume or pod: PEA, Silqua or silicula: BRASSICACEAE, capsule: DATURA Burst automatically and discharge seed Indehiscent: Cypsela(sunflower), Caryopsis(wheat, maize, rice), Scheme(mirabillis) nut(litchi) Do not burst automatically, liberation of seed, decomposition, destruction of pericarp

Question 26

Succulent/ fleshy fruit

Answer 26

``` Drupe: mango, coconut BERRY: Tomato, guava, grapes Peepo: Cucumber POME: Apple, Pear Hesperidium: orange, Citrus Balausta: Pomegranate ```

Question 27

Drupe

Answer 27

One seed fruit, diff into epicarp, meso, endo(hard, stony) Mango: epi is skin Meso is juicy p, edible Coconut: Coco's nuctifera: meso is fibrous, so fibrous drupe Walnu( Jutland regia)

Question 28

Parthenocarpic fruit

Answer 28

Fruit without fertilisation | Banana

Question 29

Seed | Dicot seed

Answer 29

Seed coat + embryo Embryo: embryo axis + 1( wheat maize) or 2cotyledons ( gram, pea) ,, + Endosperm

Question 30

Seed coat

Answer 30

Develops from interguments of ovules 2 layer: outer testa, inner tegmen Hilum is scar in seed coat where seed is attached to fruit Above hilum is micropyle small pore

Question 31

Embryo

Answer 31

Most important part of seed 2 cotyledons, fleshy, food materials End of axis are radical, plumule

Question 32

Endosperm

Answer 32

Double fertilisation Storage eg castor But in bean, gram, pea not present,

Question 33

Monocotyledons seed

Answer 33

In seed of cereal such as maize, seed coat is membranous Endosperm, embryo are below it. Orchids are no endosperm Protenatious structure: Aleutone layer Embryo is small, at groove at endosperm end. Large, shield shaped cotyledons: scutellum, short axis plume, radicle Plumele sheath: Coleptile, Radicle: coleorrhiza

Question 34

Perispermic seed

Answer 34

``` Stays in seed, perisperm Piper nigrum (black pepper) ```

Question 35

Brassicasea

Answer 35

Inflorescence corumb, corymbose- raceme Flower tetramerous Cruciform corolla Tetradynamous condition, sometime didynamous Bicarpellary, syncarpous, superior ovaries, unilocular but binocular due to replum, partiesl platform, stigma Bivins Fruit is siiqua, silicula

Question 36
