NASA Kids is an excellent site for "kids" of all ages and provides an abundance of information, images, and interesting things to do on astronomy and the space sciences. In this lesson, students learn about sources of high-energy radiation and calculate student exposure to ionizing radiation over the past year. All living things, large or small, plant or animal, are made up of cells. Most living things are made up of one cell and they are called unicellular organisms. Many other living things are made up of a large number of cells that form a larger plant or animal.

As such, they are different from unicellular single celled organisms that only consist of a single cell. Like unicellular organisms, there are a wide range of plant and animal multicellular organisms in existence. Compared to unicellular organisms, multicellular are also more complex given that they are made up of different types of specialized cells that carry out different functions. A majority of animal species, plants on land and fungi are multicellular organisms. These range from fungi human beings. Colonial organisms are made up of a group of identical cells such as the staphylococci bacteria which can survive on their own as single cells.

Plants are stationary thus their supportive tissue is made up of dead cells. Animals move, hence they possess living cells to provide energy for.

Animals are multicellular heterotrophs whose cells lack cell walls. At some point during their lives, all animals are capable of movement, although not all animals have muscles they use for this. In the most commonly encountered animals, the mobile stage is the adult, although some animals such as corals and sponges have sessile or nonmobile adult phases and mobile juvenile forms. Both animal and plant evolutionary history show the development of multicellularity and the move from water to land as well as a secondary adaptation back to water, for example dolphins, whales, duckweed, and elodea. Animals developed external or internal skeletons to provide support, skin to prevent or lessen water loss, muscles that allowed them to move in search of food, brains and nervous systems for integration of stimuli, and internal digestive systems. Organs in animals are composed of a number of different tissue types. For example, the stomach shown in Figure 1, has epithelial tissue making linings and secreting gastric juices, connective tissues.

Why Animal And Plant Tissues Are Different?


Plants are made up of meristematic and permanent tissues and are supported by shoot and root organ systems. Plants are multicellular eukaryotes with tissue systems made of various cell types that carry out specific functions. Plant tissue systems fall into one of two general types: meristematic tissue and permanent or non-meristematic tissue. Cells of the meristematic tissue are found in meristems, which are plant regions of continuous cell division and growth. Meristematic tissue cells are either undifferentiated or incompletely differentiated; they continue to divide and contribute to the growth of the plant. In contrast, permanent tissue consists of plant cells that are no longer actively dividing. Meristematic tissues consist of three types, based on their location in the plant.

Viva Voce. A group of cells having common origin, similar structure and performing a definite function is called a tissue. Tissues are found in plants and animals. Plants and animals are made up of many different kinds of tissues. For example, groups of bone cells form bone tissues and muscle cells form muscle tissue. Different types of tissues have distinctive architecture best suited for what they do. We will see that plant tissues are different from animal tissues in many ways.

Why are plant and animals made up of different type of tissue ?

Multicellular organisms are organised into increasingly complex parts. In order, from least complex to most complex:. Animal cells and plant cells can form tissues , such as muscle tissue in animals. A living tissue is made from a group of cells with a similar structure and function, which all work together to do a particular job. Here are some examples of tissues:.
