What is the outer cell layer of a cnidarian called?
The outer cell layer of a cnidarian is called the epidermis. It is a thin layer that covers the body of the organism and helps with protection and sensory functions.
What is the fate of spongo cell during development in canal system?
During the development of the canal system in sponges, spongo cells, or spongocytes, play a crucial role in synthesizing and secreting spongin, the fibrous protein that forms the sponge's supportive skeleton. As the sponge matures, spongo cells can differentiate or transform into other cell types, contributing to the overall structure and function of the sponge. Ultimately, spongo cells may either remain active in producing spongin or undergo apoptosis as the sponge's architecture stabilizes. Their fate is integral to maintaining the sponge's integrity and adaptation to its aquatic environment.
What is the purpose of the macromeres' granular nature?
The granular nature of macromeres allows them to store nutrients and molecules needed for early embryo development. These granules contain proteins, mRNA, and other factors that can be transported to other cells during cell division and differentiation.
What Difference between D cell and AA cell?
Size is the difference - both supply 1.5 volts
What is cnidoblast?
several capsules occur on the body surface. each is produced by special cell called cnidoblast
What a Cnidarian?
A jelly fish. Cnidarian's have a sting cell called a cnidnocyte which is the defining feature.
What is the major distinction between the cell layers of a sponge and those of a cnidarian?
Cnidaria are diploblastic animals, in other words they have two main cell layers, while more complex animals are triploblasts having three main layers. The two main cell layers of cnidarians form epithelia that are mostly one cell thick.

Do cnidarian have a cell wall?
The body wall of a cnidarian consists of three layers, an outer layer known as the epidermis, a middle layer called the mesoglea, and an inner layer referred to as the gastrodermis.
The inside of a sponge is lined with?
Pore cell
What is the cell in the sponge that digest food?
The osculum
Which is a feature of the sponge's body?
Has 2 cell layers
What is the feature of the sponge's body?
Has 2 Cell Layers
Does the sea sponge live birth or lay eggs?
Sexual reproduction of a sponge Sponges do not give birth or hatch from an egg. A sponge has both sperm and egg cell. The sponge releases sperm cell. The sperm cell lands in another sponge and fertilizes the egg cell in the sponge. The sperm and egg cell produce a larva. A larva is an immature form of an animal that looks different from the adult form. The larva gets taken away by the current and lands on a hard surface and grows into a sponge. Budding of a sponge ( a form of asexual reproduction) off the sides of a sponge a sponge grows. That sponge breaks off and lands on a hard surface and is a sponge.
Which sponge cell arrangement is close to a true tissue?
pinacycotes
How does a cnidoblast cell's structure help it?
These are stinging cells found in cnidarian and coelenterate. Each of them bears a stinging cell organelle called nematocyst which is used in offence, defence and attachment of animal.
