Groups of cells with a common structure and function are called tissues. Tissues work together to perform specific tasks within an organism, contributing to the overall function of organs and systems. There are several types of tissues in animals, including epithelial, connective, muscle, and nervous tissue, each serving distinct roles. In plants, tissues are categorized into types such as vascular, ground, and dermal tissues.
Cells grouped together according to size, shape, and function are called tissues. Tissues are organized collections of similar cells that work together to perform specific functions in an organism. There are four primary types of tissues in animals: epithelial, connective, muscle, and nervous tissue, each with distinct roles in the body. In plants, tissues are categorized into meristematic and permanent tissues, among others.
In complex plants and animals, tissues are organized into distinct types that perform specific functions. In plants, there are three primary tissue systems: dermal, vascular, and ground tissue, each contributing to protection, transport, and photosynthesis, respectively. In animals, tissues are categorized into four main types: epithelial, connective, muscle, and nervous tissue, which work together to form organs and systems essential for survival and homeostasis. This organization allows for specialization and efficient functioning within the organism.
a grouping of tissues into a distinct structure, as a heart or kidney in animals or a leaf or stamen in plants, that performs a specialized task.
Yes. Somewhat simpler than us, but not primitive.
Xylem and phloem are two cardiovascular tissues in plants. The two tissues aid in helping the plant to absorb water and move it through their structure.Xylem and phloem are twocardiovascular tissues in plants

Yes, eukaryotic organisms can have tissues, particularly multicellular ones like plants and animals. Tissues are groups of similar cells that perform a specific function, and they are organized into organs and systems. In animals, for example, there are four main types of tissues: epithelial, connective, muscle, and nervous tissue. Plants also have specialized tissues, such as xylem and phloem, that facilitate various functions.
The phylum Porifera (sponges) is the only animal phylum that lacks true tissues and symmetry. Sponges are simple multicellular organisms with specialized cells, but they do not have tissues that are organized into distinct structures like other animals. Additionally, sponges exhibit asymmetry rather than bilateral or radial symmetry found in other phyla.
A major tissue is a group of cells that work together to perform a specific function in the body. The four primary types of major tissues in animals are epithelial, connective, muscle, and nervous tissues. Each type has distinct characteristics and roles; for example, epithelial tissue covers and protects surfaces, connective tissue supports and binds other tissues, muscle tissue facilitates movement, and nervous tissue transmits signals. In plants, the major tissues include dermal, vascular, and ground tissues, each serving vital functions in growth and nutrient transport.
There are quite a few animals that contain tissues but lack complex organs. One of these animals is the jellyfish.
No, sponges do not have true tissues like other animals. They are classified as Porifera and are considered the simplest animals, lacking specialized tissues and organs. Sponges have a porous body structure with specialized cells but no distinct tissue layers.
