Why is a sponge hard when dry and soft when wet?
A dry sponge is hard because the water has evaporated, leaving the sponge's cellular structure collapsed and less flexible. When water is added, the cells absorb water and expand, allowing the sponge to become soft and flexible.
What protein makes up a sponge?
The flexible protein fibers that make up a sponge are called spongin. The hard, tiny spikes found in sponges are called spicules, and they are made of silica or calcium carbonate.
Why is sponge cake a solid?
Sponge cake is considered a solid because it has a defined shape and volume, and it does not flow like a liquid. It maintains its structure when baked due to the protein network formed by the eggs and flour, giving it a solid consistency.
What is the sharp structure called in a sponges body?
The sharp structure found in a sponge's body is called spicules. These spicules provide structural support and protection for the sponge.
What happens to a sponge when it is cut in half?
When a sponge is cut in half, each half is capable of regenerating into a new sponge. The cells within the sponge are flexible and can reorganize to form a new structure if provided with appropriate conditions. This regenerative ability allows sponges to quickly recover from physical damage.
What is a flexible network for the internal support of a sponge?
Spongin A+
Is sponge flexible?
Yes it is flexible.
Why is a sponge hard when dry and soft when wet?
A dry sponge is hard because the water has evaporated, leaving the sponge's cellular structure collapsed and less flexible. When water is added, the cells absorb water and expand, allowing the sponge to become soft and flexible.
What two substances gives the sponge support?
spongins and spicules give the sponge support:)
What is the network sponge bob is on?
YTV
What materials make up a sponge?
A sponge is typically made up of small, porous holes called "ostia" which are surrounded by a network of cells known as "choanocytes." These cells help to filter and move water through the sponge's body, enabling it to feed and respire. Sponges also contain a protein called "spongin" which gives them their flexible and soft texture.
The collar cells draw water through the sponge's many pores and into the internal cavity of the sponge by beating their?
flagella
What structures provide support to the sponge?
What supports a sponge it its agility to love god with all its tentacles, rays, and hole on the bottom of itself.
What are the 2 functions of spicules?
The spicule in a sponge is its skeleton. It provides strength in the sponge.
Sponges can reproduce asexually by?
budding or fragmentation. Budding involves the growth of a new sponge from the parent sponge, while fragmentation occurs when a piece of the sponge breaks off and grows into a new sponge.
What is the function of the spongin ans spicules?
Spongin provides structural support in certain marine sponges by forming a flexible, protein-based skeleton. Spicules are tiny, needle-like structures made of calcium carbonate or silica that also provide structural support and protection in sponges, as well as help deter predators.
What type of sponge material supports a sponges body structure?
A network of spongin or spicules.
