Question

What is the difference between Palea and Lemma?

Answer 1

In the onset period the flower is ready for pollination. Pollination is the moving of pollen grains from the male flower to the female flower. Flowers which are diurnal anthesis are mostly brightly colored which helps in attracting insects such as- moths and butterflies. Anthesis is the phenomenon of opening of flowers for a specific period of time.

Complete answer:
Pollination is the act of moving pollen grains from the male flower to the female flower. There are different types of pollination like-self-pollination and cross pollination and these categories are the main ones, others maybe sub-categories. So, let us gather more about pollination in flowering plants.
Difference between palea and lemma is-

Palea	Lemma
palea is the flower’s receptacle.	lemma is specialized bracts or bracteate.
Example- Rice, in rice the palea is in bended form and facing towards the lemma.	Example- Grass. Bracts of grasses.
Also, the internal chaff or husk is palea.	Lemma is part of spikelet. Also bears a long bristle known as awn.
When pollen from the male part of the plant falls directly to the female part of the same flower results in fertilization.	Dehiscence of anthers means- falling of anthers to stigma so that pollination can take place.

Anthers are the male organ in a flower and they need to be transported in order for pollination to occur. Such pollination is termed as self-pollination. Opening of floral bud- opening of flower or floral bud is anthesis.

Note:
Anthesis, as we discussed, is the period of expansion of flowers. The flower expands and remains open during day time or night time. Depending on the viability of organs. The diurnal flowers attract daytime insects to suck nectar and pollination to take place while the nocturnal flowers are opened during night time so that insects like moth species come to feed nectar.
