Q

a fruit from several carpels with inner pulp juice sacs or vesicles enclosed in leathery rind.

A

Hesperidium

Fleshy fruits

10
Q

the pericarp is thick and the rind is hard.

A

Pepo

Fleshy fruits

11
Q

one-seeded fruit with the pericarp distinctly divided into thin skin-like exocarp, thick fleshy mesocarp and hard, stony endocarp.

A

Drupe

Fleshy fruits

12
Q

fleshy part of the fruit develops from the receptacle of the flower. It is usually characterized by a papery pericarp.

A

Pome

Fleshy fruits

13
Q

Dry fruits classification

A

dehiscent or indehiscent.

14
Q

fruit splits open along definite seams at maturity and may contain several seeds

A

Dehiscent fruits

15
Q

has one carpel and splits along two seams.

A

Dehiscent fruits

Legume/ pod

16
Q

has one carpel and splits along one seam.

A

Dehiscent fruits

Follicle

17
Q

fruit of two or more united carpels and splits in a variety of ways.

A

Dehiscent fruits

Capsule

18
Q

fruit of two fused carpels that separate, leaving a persistent wall between them.

A

Dehiscent fruits

Silique

19
Q

do not open along definite seams or points when mature. These usually contain only one or two seeds. Some types of indehiscent fruits are:

A

Indehiscent fruits

20
Q

one seed can be separated from the ovary wall except at point of attachment to the inside of the pericarp.

A

Achene

21
Q

one seeded the coat of which is completely fused to the inner surface of the pericarp.

A

Caryopsis/ Grain

22
Q

an achene-like fruit with wing-like outgrowth.

A

Samara

23
Q

one seeded fruit similar to achene but with a very hard and thick pericarp.

A

Nut

24
Q

Some fruits may develop from floral parts other than the ovary. These parts are often fused to the ovary and are so well developed that they constitute the major part of the fruit.

A

true

25
Q

the arrangement of ovules on the placenta

A

placentation

26
Q

placentation

A
  1. Axile
  2. Parietal
  3. Free-central
  4. Marginal
  5. Basal
27
Q

ovules are attached to a central axis in compartmentalized ovary.

A
  1. Axile
28
Q

ovules are found along the walls of a uniloculate ovary. (Ex: Papaya)

A
  1. Parietal
29
Q

ovules are attached to a central axis of a uniloculate ovary

A
  1. Free-central
30
Q

There is only one elongated placenta on one side of the ovary, as ovules are attached at the fusion line of the carpel’s margins

A
  1. Marginal
31
Q

The placenta is at the base (bottom) of the ovary

A
  1. Basal
32
Q

one sperm fertilizes egg to make zygote; other fertilizes polar bodies to make 3N endosperm (used for food)

A

double fertilization
