Simple fleshy Fruit

A

A fleshy fruit that derived from a single ovary

18
Q

Carpel

A

One of the leaflike, seed bearing structures that constitute the innermost whorl of a flower

19
Q

Drupe

A

20
Q

BErries

A

21
Q

Pomes

22
Q

Follicle

A

A dry fruit that is derived from a single carpel and opens on one side only to release its seed

23
Q

Legume

A

The long seed pod of a leguminous plant

24
Q

Siliques

A

the long, narrow seed pod of many plants of the cabbage family, splitting open when mature

25
Capsules
In botany, a capsule is a dehiscent fruit which, at maturity, split apart (dehisce) to release the seeds within.
26
Achene
achene, dry, one-seeded fruit lacking special seams that split to release the seed.
27
Nuts
A nut is a fruit consisting of a hard or tough nutshell protecting a kernel which is usually edible
28
Caryopsis
a dry one-seeded fruit in which the ovary wall is united with the seed coat, typical of grasses and cereals
29
Samaras
A samara is a winged achene, a type of fruit in which a flattened wing of fibrous, papery tissue develops from the ovary wall (Ohrenkneifer)
30
Schizocarp
a dry fruit that, when mature, splits up into mericarps.
31
Aggregate Fruit
consist of several separate carpels of one apocarpous gynoecium (e.g., raspberries where each unit is a single carpel)
32
Multiple fruits
Multi-fruits, also called collective fruits, are fruiting bodies formed from a cluster of flowers, the inflorescence Pineapple
33
Cotyledons
cotyledon, seed leaf within the embryo of a seed. Cotyledons help supply the nutrition a plant embryo needs to germinate and become established
34
Plumule
The bud of a young plant; the portion of the plant embryo giving rise to the first true leaves, especially above the cotyledons
35
Picotyl
epicotyl is important for the beginning stages of a plant's life. It is the region of a seedling stem above the stalks of the seed leaves of an embryo
36
Hypocotyl
the part of the stem of an embryo plant beneath the stalks of the seed leaves or cotyledons and directly above the root
37
Radicle
the part of a plant embryo that develops into the primary root
38
Coleoptile
a sheath protecting a young shoot tip in a grass or cereal
39
Coleorhiza
a sheath protecting the root of a germinating grass or cereal grain
40
Seed germination
Seed germination is defined as the sum of events that begin with hydration of the seed and culminate in emergence of the embryonic axis (Keimung)
41
Seed dormancy
Seed dormancy is an evolutionary adaptation that prevents seeds from germinating during unsuitable ecological conditions
42
Seed longevity
Seeds of many plant species are extremely tolerant to harsh environmental conditions provided they are in a state of desiccation. In this dry state, their metabolic activity is drastically reduced to a very low level (quiescence) while retaining their ability to germinate for considerable periods
