The cell wall is a tough and rigid layer that surrounds some types of cells. It is located outside the cell membrane and its main function is to provide rigidity, strength, protection against mechanical stress and infection. It can also provide the cell with limited plasticity that will prevent the cell from rupturing due to turgor pressure.

The bacterial fission occurs by the following method:
The DNA replicates. The replicated DNA is copied and it moves to the opposite sides of the cell. The length of the parent cell increases. The cell divides from the center with distribution of equal amount of DNA. After this, the cell wall is formed.
In protist fission: In protist fission, the nucleus of the parent cell divides many times. After this cytoplasm separates and forms around the daughter nuclei.
Answer:
The correct answer is -Sponges lack true tissue but have morevariation in cell type than animas in oter phylum.
Explanation:
Sponges are belong under phylum porifera which have diverse form encrusting sheets to volcano shaped mounds.
The tubes that contain in their body are differ in size from millimeter upto one meter.
The poriferans contain canal system and with help of this, they pump water which enters through a specialed pores called ostia that flows through canal called spongocoel and finally the water exits from their body through oscula.
The sponges show complex organization as their body contain single tube with 2 cell layer thick.
Ascon,leucon,sycons are the level of complexity.
