Question

The characteristics of poaceae are
A) Pedicellate, bracteates, bisexual, tetramerous, actinomorphic, complete and superior ovary
B) Pedicellate, bracteates, bisexual, pentamerous, zygomorphic, complete and superior ovary
C) Sessile, bracteates, bracteolate, incomple uni-or bisexual, perianth modified into lodicules, stamens three, syncarpous, superior ovary and feathery stigma
D) Bracteate, bracteolate, bisexual, pentamarous, actinomorphic, complete and superior ovary
E) Bacteate, unisexual, actinomorphic, stamens five, inferior ovary

Answer 1

Hint: The leaves are mostly sessile. Typically the flower is bisexual but unisexual can also be observed. Its stigma is adaptation of anemophilous plants in which flowers are pollinated by wind.

Complete answer:
First we should know about the family poaceae to answer this question. The family poaceae is generally referred to as the family of grass. It is one of the major families of angiosperm. It is made up of 620 separate genera and 6,000 species. The delegates are cosmopolitan in distribution. All three ecological forms of plants are described as hydrophytes, xerophytes and mesophytes. It is portrayed in India by 850 species.
Now, let us find the solution from the options-
Flowers are typically bisexual or rarely unisexual, inconspicuous, sessile, incomplete, bracteate, hypogynous, and zygomorphic.
Perianth is missing or is defined by 2 (sometimes 3) scales called lodicules. They are fleshy or hyaline lodicules.
Androecium contains 1 to 6 free stamens, usually 3. Their filaments are fragile. Although their anthers are versatile.
They have a globe-shaped stigma that is long and thin which form a feathery stigma they can easily catch pollen from the wind.
Gynoecium contains a superior ovary, unilocular with a single ovule, style is either absent or short.

Thus, the correct answer is option (C) Sessile, bracteates, bracteolate, incomple uni-or bisexual, perianth modified into lodicules, stamens three, syncarpous, superior ovary and feathery stigma.

Note: Humans are largely economically dependent on these groups. They are considered the most important plant family for humans. Poaceae including staple food grains, cereal crops, lawn, animal grasses, and forage grasses, bumboo (widely used for construction) contribute to human development.
