What is the other name of Microspore?
When a microspore germinates, it is known as a pollen grain.
What is the common name of Selaginella?
Selaginella stellata, also recognized by its common name, starry spikemoss or starry spike-moss, is a species of spikemoss of the family Selaginellaceae. It is a type of lycopod that grows naturally in Mexico and Central American countries like Guatemala and Belize and can also be found in the state of Hawaii.
Where can you find the plant’s Microspore?
As the anther of a flowering plant develops, four patches of tissue differentiate from the main mass of cells. These patches of tissue contain many diploid microsporocyte cells, each of which undergoes meiosis producing a quartet of microspores.
How do you take care of Selaginella?
Keep the soil moist but never soggy and avoid using cold water. A Selaginella plant becomes totally dormant and the leaves roll into tight little brown balls when there is no moisture. Once the Selaginella is watered, it turns green and starts to grow again. A Selaginella plant needs very little plant food.
What is the difference between microspore and pollen grain?
Microspores are small haploid structures that give rise to the male gametophyte. Pollen grains are haploid cells that form the male reproductive gamete of the plant. Microspores are found in both seedless and seed plants. Pollen grains are found in seed plants only.
What is microspore mother cell?
Pollen mother cells (PMCs), also called microspore mother cells, are derived from the sporogenous tissue found in the anther. They are diploid in nature. The PMCs undergo two meiotic divisions to form four haploid microspores. The microspores undergo further mitotic division to form the pollen grains.
What is Selaginella cone?
Selaginella is a pteridophyte. It is also called spikemoss or club moss. It is the largest and the only living genus of the family Selaginellaceae. It contains more than 800 species distributed all around the world with the highest diversity found in the tropical regions. They are seedless vascular plants.
What is ligule Selaginella?
A small membranous structure that develops on the upper surface of a young leaf base in certain clubmosses, for example Selaginella. It withers as the plant matures.
How does a microspore become pollen?
The cells of sporogenous tissues undergo meiotic division to form microspore tetrad. As the anther mature and dehydrate, the microspore dissociate and develops into pollengrains. The pollen grain represents the male gametophytes.
How does Selaginella look like?
Selaginella Uncinata It is often referred to as Peacock Spikemoss thanks to the bright iridescent, blue-green color of its leaves. The leaves are oblong in shape and appear paper-like and very delicate. They grow in a trailing or creeping direction but also grow up to about 2-3 inches in height.
Is Selaginella an indoor plant?
Selaginella plants like temperatures ranging from 50°-75° F. Because of this, some varieties can work well as houseplants, but they are more commonly found growing outdoors.
Is tetrad a pollen?
Tetrad, a group of four haploid and immature pollen grains in tetrahedral fashion produced by meiotic microsporogenesis.
