Web3. Tissue Level: The cells form poorly defined tissues, e.g. Cnidarians (=coelenterates), ctenophores. 4. Organ-System Level: The cells are organised into tissues, tissues into organs and organs into organ systems. Except sponges and coelenterates, all the animals of the kingdom animalia have organ-system level of organisation. WebN ervous tissue develops from the embryonic ectoderm, the layer covering the embryo that becomes the epidermis. The nervous tissue is composed of two cell types: neurons and glia. The main function of nervous tissue is the processing of information coming from the external and internal environments, and then triggers a response.

WebAnatomy of a tree. A: The outer bark is the tree's protection from the outside world. Continually renewed from within, it helps keep out moisture in the rain, and prevents the tree from losing moisture when the air is dry. It insulates against cold and heat and wards off insect enemies. B: The inner bark , or “phloem”, is pipeline through ... WebAns. 1. Muscular tissue, 2. Nervous tissue, combination of both the tissues are responsible for movement in our body. 2. What does a neuron look like? Ans. A neuron consists of a cell body with a nucleus and cytoplasm, from which long thin hair like parts arise. Each neuron has a single long part called the axon, and many small, short branched ... Webmolecules and junctions. A tissue may contain several different cell types. For example, muscle tissue in animals may consist not only of specialised muscle cells, but also of connective tissue cells, blood vessel cells, nerve and other cells. Tissues allow the different functions of an organism to be apportioned to specialised cell assemblages. tj\u0027s big boy
