single-celled organisms such as protozoa Exhibits protoplasmic grade tissue. 2. All similar functions are confined within the boundaries of a cell.

What is the protoplasmic grade of tissue?

A. The protoplasmic grade of the tissue.

All life functions are confined within the boundaries of a single cell. Within the cell, the protoplasm is differentiated into organelles capable of performing specialized functions. (eg, protists)

Which of the following is an example of a tissue-organ level?

The organ level of tissue is where two or more tissues work together to achieve a specific function. E.g, bladder Consists of an inner layer of epithelial tissue, composed of various connective tissues combined with (smooth) muscle.

What is cellular organization grade?

tissue at the cellular level.Cellulite is functionally differentiated cell aggregates. The division of labor is clear, so some cells are concerned with reproduction and others with nutrition. …sponges are at this tissue level.

What does the organizational hierarchy of an organization mean?

In the organizational hierarchy of the organization, Cells begin to function in a unified manner to accomplish tasksCnidaria are generally considered to be at this tissue level and make them more advanced than Porifera.

What level of organization does a sponge have?

sponge has cellular tissuemeaning their cells are specialized so that different cells perform different functions, but similar cells are not organized into tissues, the body is a loose aggregation of different kinds of cells.

What is the body structure level in the sponge?

sponge has cellular organization. They do not possess any structure that could be considered an organ. For example, sponges have no stomach or kidneys. Instead, various types of sponge cells are responsible for bodily functions, the day-to-day activities that sustain life.

What is the tissue class of the animal?

Living organisms consist of four levels of organization: cells, tissues, organs and organ systems.

What does organizational hierarchy mean?

organization level level of cell arrangement… organization at the cellular level: it is a loose aggregate of cells in which cells are functionally distinct from each other. Tissue level of tissue: In this case, different cells that perform similar functions are arranged into tissues.

What are the 5 levels of organization?

Summary: The main organizational levels of the body, from simplest to most complex, are: Atoms, molecules, organelles, cells, tissues, organs, organ systems and human organisms.

What is an example of an organism?

The definition of an organism is an organism, such as a plant, animal, or unicellular life form, or something that has interdependent parts and is compared to living things.An example of an organism is dog, human or bacteria.

What is the chemical level of the tissue?

The chemical level of the tissue is easiest level. It includes the building blocks that make life possible – atoms. Atoms join together in various combinations to form molecules that perform some of the basic functions of life. … atoms combine through chemical reactions to form compounds and molecules.

What tissue connects body parts?

connective tissue Supports other tissues and holds them together (bone, blood and lymphatic tissue). Epithelial tissue provides the covering (skin, lining of various passages in the body).

What do you mean by protoplasm?

Protoplast (/prəʊtə(ʊ)ˌplaz(ə)m/, plural protoplasm) is the living part of the cell surrounded by the plasma membrane. In some definitions it is a general term for cytoplasm (eg, Mohl, 1846), but for others it also includes nucleoplasm (eg, Strasburger, 1882).

Which phylum has the organ level?

The organ level of body tissue is found in Platyhelminthes .

Are sponges multicellular?

sponge is one of them Simplest multicellular animal Traditionally regarded as the oldest extant animal clade.

What is the difference between organizational hierarchy and symmetry?

The hierarchy of a tissue refers to the level at which cells are arranged. … tissue at the organ system level (eg: nematodes, annelids, arthropods, mollusks, echinoderms, and chordates). Symmetry is a characteristic by which animals are distinguished.

What are the three types of body symmetry?

Animals can be classified by three body symmetries: Radial symmetry, bilateral symmetry and asymmetry.

Give an example what is the exact difference between organizational hierarchy and symmetry?

Organizational Hierarchy Tell Us organicism essay Which is determined on the basis of higher cellular, tissue, organ and compositional levels. Symmetry is the division of organicism.

What is a real Coelom?

animals with true coelom Coelomates or Coelomates. A true coelom is one that appears as a cavity in the embryonic mesoderm. It is found in • annelids, arthropods, mollusks (schizocaea), echinoderms and chordates (intestinal cavity).

What are the tissues in animals?

Living organisms are made up of cells organized into tissues that combine themselves to form Organs and Systems…these different types of cells are not only scattered randomly, but similar cells that perform the same function are arranged in groups.

Which symmetry is most common in animals?

Most animals are bilateral symmetry Divide their bodies into left and right sides with a line of symmetry, with a « head » and « tail » in addition to the top and bottom. Only sponges (Porifera phylum) have an asymmetrical body structure.

What’s in the sponge?

inside the sponge, tiny hair-like structures called flagella An electrical current is generated to filter bacteria in the sponge cells and trap food in them. Their strong bone structure helps sponges withstand the large amounts of water that flows through them every day.

What do all sponges have in common?

Sponges are similar to other animals in that multicellular, heterotrophic, lacking cell walls and producing sperm cells. Unlike other animals, they lack true tissues and organs. Some of them are radially symmetrical, but most are asymmetrical.

What are the three layers in a sponge?

The body wall consists of three layers: outer layer of flat epidermal cells. an intermediate layer consisting of a gel-like substance and migrating amoeba cells within the layer.An inner layer composed of flagellate cells and collar cells (also called chondrocytes)
