Question

What is staminode?

Answer 1

Androecium is the third whorl And this inner to the Corolla. It's the male system composed of stamens. A press release consists of the anther, connective, filament. Anthers are bilobed. Each lobe contains two microsporangia or pollen sacs. Pollens are produced in pollen sacs. Staminode is the structure associated with anther.

Complete answer:
Staminode: The stamen which doesn't produce pollen grains is thought because of the sterile stamen. These Stamens are nonfunctional. The sterile stamen is either called an abortive statement or staminode.
Stamina may be a rudimentary, sterile, or abortive stamen which suggests it doesn't produce pollen or it resembles a stamen without its anther.
-Part of the flower referred to as the stamen. Staminodes are identical to Stamen but sterile and don't participate in reproduction.
-They are inconspicuous are usually found within the inner whorl of Flowers, but in some Flowers, there farewell that they Protrude from the Corolla.
-Staminal may be a modified statement. The foremost common modification is that the filament is expanded to make a petal sort of a blade which we called staminode.

The three possible functions of stammers are as follows:
-They are attractive so that they help in pollination, they need some nutritional values and structural function.
-Stamina words are of two types: true staminodes and pseudo staminodes
-True staminodes: They Odd modifications of steaming or they're derived from the stamen, while pseudo staminodes are only morphologically like the Stamen.
-Pollen grains will be considered because the male damage that's produced by the most reproductive
-The stamens in Caesalpinioideae Are mostly ten but ten because of the reduction in staminodes. Staminodes are found in Caesalpinioideae and a few other families. Sometimes, the staminodes are modified to provide nectar as in Witch Hazel. An example of stamina formation is wild roses they need only five petals and lots of stamens but after we cultivate a rose plan it's been selected for several apparent petals but staminodes) and some functional stamens.

Note: A Lily flower has sixteen stamens but later they become short and sterile called staminode. This happens because of evolution therefore the formulation of staminode is an evolutionary process. Stamen of a flower may be united or free and is the reproductive structure of male.
Sterile stamens are usually known as staminodes.
