What else can I help you with?
How can you contrast a pollen grain and a seed?
Pollen grain after meiosis in the microspore mother cell and has haploid set of chromosomes. A seed develops from ovule after fertilization, in which the number of chromosomes get doubled. Pollen grain is unicellular, microscopic structure, a seed is multicellular macroscopic structure.
Is a pollen grain spore?
No, a pollen grain is not a spore. A pollen grain is a male gametophyte produced by seed plants for the purpose of reproduction, while a spore is a reproductive cell that can develop into a new organism without the need for fusion with another cell.
What kind of spore becomes a pollen grain in seed plants?
The microspore after resulting from meiosis in the microspore mother cell become pollen grain. It takes place inside the anther lobe in the sporogenous tissue and the entire process is called microsporogenesis.
What is the structure that develops into a pollen grain?
First pollen falls from a male cone onto a female cone. In time a sperm cell and an egg cell join together in an ovule on the female cone
What is difference between ungerminated pollen grain and germinated pollen grain?
Ungerminated pollen grain is inactive and has not started the process of fertilization, while germinated pollen grain has started growing a pollen tube towards the ovule for fertilization. Germinated pollen grain is actively involved in the fertilization process, while ungerminated pollen grain is not.
What structure developes into pollen grain?
Microspore
A mature microspore that contains a microgametophyte?
pollen grain
What do micro spores develop into?
Each microspore can develop into a male gametophyte,or pollen grain

What is the name given to the structure in the flower in which the sperm cell is formed?
The structure in the flower where sperm cells are formed is called the anther. It is part of the male reproductive organs of the flower and is responsible for producing pollen grains containing the sperm cells.
What is difference between ungerminated pollen grain and germinated pollen grain?
Ungerminated pollen grain is inactive and has not started the process of fertilization, while germinated pollen grain has started growing a pollen tube towards the ovule for fertilization. Germinated pollen grain is actively involved in the fertilization process, while ungerminated pollen grain is not.
Do Dicot have pollen grain?
yes Dicot have pollen grain and in Dicots pollen grain possess 3 germ pores
What makes seeds when combined with a flower's eggs?
This tiny grain is called pollen grain.
The male sex cell in a plant?
The male sex cell in a plant is called a pollen grain. It is produced in the anther of a flower and is responsible for fertilizing the female sex cell, located in the ovule, during the process of pollination.
