level of organization in plant and animal

Introduction - The animal kingdom includes eukaryotic multicellular organisms which exhibit heterotrophic nutrition. They are commonly known as animals and differ characteristically from the other major groups of plants, in their capacity to be able to move. ..

Control and Coordination in Animals - Animals are different from plants because of their ability of locomotion. This ability probably developed as they have to search for food, unlike the plants that are autotrophic. Since they move from one place to another,..

Summary - All higher multicellular animals, called eumetazoans, exhibit a tissue and higher levels of organization There are four primary tissues in animals epithelial, muscular, connective and nervous Epithelial tissue (epithelium) is the simplest. It is ava..

Flowers are primarily concerned with sexual reproduction. But, in some plants such as Agave, the flower bud becomes modified into specialised structures called the bulbils . The bulbils are fleshy on account of storage of food in the floral leaves. The bulbils drop from the parent pl..

Growth is defined as an increase in the size and weight of an organism due to synthesis of new protoplas..

Nitrogen Fixing Organisms - Some bacteria are known to fix the atmospheric nitrogen for their own biological activity. This natural phenomena is commercially utilized to increase the nutrient supply to crops. There are two types of nitrogen fixing bacteria. They are a) Symbiotic N 2 fixin..

Definition - Growth is defined as an increase in the size and weight of an organism due to synthesis of new protoplasm. Growth takes place at 2 different levels in an organism..

The space between soil particles on the surface of earth is called pore space. It is of two types - micro and macro pores. Most of the water is held in micro pores. Pores, which are available for plant roots. Surface soil pore spaces are generally filled with air and water. Wate..

The different steps or levels in a food chain form different trophic levels. The illustration below is self-explanatory. This is the ecosystem that can exist on land. Trophic levels Thus a food chain of four levels is built up where green plants fix..

Saprotrophs are decomposers and liberate energy for their own use by breaking down complex organic matter from the dead bodies of other organisms. At the same time this process releases vital chemical elements into the soil which are absorbed by autotrophs. Thus saprotrophs ..
