pore space
The percentage of pore space in soil or rock can vary significantly depending on the composition and porosity of the material. In general, soil may have a pore space ranging from 25% to 60%, while rocks typically have much lower pore space, often less than 10%.
Infiltration is the movement of surface water into rocks or soil through cracks or pore spaces.
Sandy soil typically has larger pore spaces compared to clay soil. This is because clay particles are much smaller and more tightly packed together, reducing the size of the pore spaces between them. This difference in pore space influences factors like water drainage, aeration, and root penetration in the soil.
Pore space is the volume of open space between soil particles where air and water can infiltrate and be stored. It affects soil properties by influencing water infiltration, retention, drainage, and aeration, as well as providing habitat for soil organisms and roots. Soil with more pore space typically has better fertility, structure, and drainage properties compared to compacted soils with limited pore space.
Function of Anal-pore
Waste exits the paramecium through a structure called the anal pore, located at the posterior end of the cell. This pore allows for the expulsion of unwanted materials and maintains the cell's internal environment.
A flatworm has both a mouth pore for ingesting food and an anal pore for excreting waste.
A pore which protozoa use to eat their prey.
Anal Pore
I wish i new...I was looking up the question myself
I studied a flatworm known as the planarian, which possesses a mouth pore for ingesting food and an anal pore for excreting waste. These pores are part of the digestive system of the planarian, allowing it to efficiently process nutrients and eliminate waste.
Undigested food leaves the Paramecium through a structure called the anal pore, which serves as the organism's anus. The anal pore is located at the posterior end of the Paramecium and allows undigested food particles to be expelled from the cell.
The function of the anal canal is to transmit and lubricate stool as it bypasses externally from the rectum.
Eliminates undigested materials. In the paramecium. (More commonly known in larger organisms as the anus or Butthole)
Helps to keep the surface of the earthworm moist.
The anal canal serves to transmit and lubricate stool as it passes externally from the rectum
