A germ pore is a small pore in the outer wall of a fungal spore through which the germ tube exits upon germination. It can be apical or eccentric in its location, and, on light microscopy , may be visualized as a lighter coloured area on the cell wall.

The meaning of GERM PORE is a pore, pit, or thin area in the outer wall of a spore or pollen grain through which the germ tube or pollen tube makes its exit on germination.

Germ pores are openings in the spore wall for exit of the germination tube. When present, the number (except in some species of Gelasinospora), position, size, and arrangement (for some species of Gelasinospora) are diagnostic of some species. Terminal pores …

Aug 17, 2021 · Exine is the outermost layer of pollen grain which is made up of a highly resistant organic material called sporopollenin. Exine should be hard to withstand high temperature, strong acids and alkali. Germ pores are prominent apertures where sporopollenin is absent which later on protrudes out as pollen tube.

The germ pore helps in the formation of the pollen tube and the release of the male gametes during fertilisation. There are usually three germ pores in dicots (tricolpate) and one in monocots (monocolpate).

germ pore - a pore in the outer wall of a spore or pollen grain through which the germ tube or pollen tube makes its exit on germination

The germ pore plays a paramount function in plant fertilization. It assists in the formation of pollen tubes and delivers male gametes during the process of fertilization. Intine is the inner wall which is thin and continuous and made up of cellulose and pectin.

Germ pore: A germ pore is a little pore in the external mass of a contagious spore through which the germ tube exits upon germination. It tends to be apical or flighty in its area, and, on light microscopy, might be pictured as a lighter hued region on the cell divider.

Some spores have a hole in the cell wall, through which the first strand of germinating mycelium (or germ tube) emerges. If the cell wall is slit, in a similar fashion, from one end to the other, this is called a germ slit. Often, the germ pore is at one end of …
