-
Embryo
-
Cotyledons
-
Endosperm
-
Plumule
Cardamoms or Cardamons are ripe and dried fruits of
-
Elettaria cardamomum
-
Cinnamomum zeylenicum
-
Eugenia caryophyllata
-
Zingiber officinale
Cardamoms are ripe and dried fruits of Elettaria cardamomum, commonly called green or true cardamoms. They are called the 'queen of spices' because of the aroma and taste.
In angiosperms, triple fusion produces
-
Polar nucleus
-
Secondary nucleus
-
Primary endospermic nucleus
-
Zygotic nucleus
Double fertilization process is observed in angiosperms in which syngamy takes place in the beginning. After syngamy the pollen tubes releases two male gametes, one fuses with the nucleus of egg cell and the other with the central cell and forms primary endosperm nucleus (PEN). The process is called as triple fusion as endosperm is triploid in nature.
Endosperm of flowering plants develops from
-
Haploid nucleus
-
Diploid nucleus
-
Triploid nucleus
-
Tetraploid nucleus
-
Polyploid nucleus
Nucellus in fertilized ovuled is known as ______________.
-
Perisperm
-
Endothecium
-
Perithecium
-
Epistase
Seeds contain embryo.
-
True
-
False
A fruit is a
-
Ripened ovary
-
Ripened ovule
-
Seed plus its integuments
-
Fused carpel
Fruit is a seed-bearing structure in flowering plants formed from the ovary after flowering. Fruits are the means by which angiosperms disseminate seeds. A fruit results from maturation of one or more flowers, and the gynoecium of the flower forms all or part of the fruit. The outer, often edible layer, is the pericarp, formed from the ovary and surrounding the seeds, although in some species other tissues contribute to or from the edible portion. The pericarp may be described in three layers from outer to inner, the epicarp, mesocarp and endocarp.
The ovary of a flower grows into a fruit.
-
True
-
False
- Fruit is a ripened ovary of the plant which also bears certain accessory structures in it. It is a part of the plant that develops from the fertilized ovary. Ovules in the ovary develop into seed. The ovary is the part of the female reproductive structure of the flower, the pistil. Ovary bears ovules inside it.
Plumed seeds occur in
-
Naravelia
-
Taraxacum
-
Calotropis
-
Colutea
Plumed seeds occur in Calotropis. The seeds are compressed, broadly ovoid, with a tufted micropylar coma of long silky hair. The crown of the hair on the seeds favouring anemochory give the plumed appearance.
Upon fertilization while ovule develops into seed. Which structure develop from a carpel?
-
Testa
-
Tegmen
-
Pericarp
-
Perisperm
Upon fertilization while ovule develops into seed. Pericarp develops from carpel. The pericarp is typically made up of three distinct layers, the epicarp, which is the outermost layer, the mesocarp, which is the middle layer and the endocarp, which is the inner layer surrounding the ovary or the seeds. In a citrus fruit, the epicarp and mesocarp make up the peel.
Therefore, the correct answer is option C.
