If a leaf appears toothed, it is a Crenate and Serrate.
Polyp cnidarian form is the characterized by the cylindrical body with which a mouth surrounded by the tentacles at the end of cylinder and opposite where it can attached to the substrate or the colonial tissue
A colony of the single-cell organisms is also known as the colonial organisms. The difference between the multicellular organism and the colonial organism is that the individuals organisms that may form the colony or the biofilm can,
if separated, or survive on their own, while the cells from the multicellular organism (e.g., liver cells) cannot be Colonies usually that do not have the specialized tissues or the organs. Corn is the complex plant that may has many types of the cells that form the tissues and the organs with the different jobs. Each plant is made of the billions of cells

Multi cellular organisms are composed of many cells whereas unicellular organisms are composed of single cell. Multicellularity is indeed a progressive attribute of evolution where cells form tissue which forms organ and then organ system and finally an organism. Both multi cellular and unicellular organisms has advantages and disadvantages of their own. One of the main disadvantage of multi cellular organisms is that due to such a complex composition and functioning they require a large amount of energy for their maintenance and survival. Different organs and system require a huge amount of energy when it comes to comparison with unicellular organisms. A large amount of energy is also wasted in all these life processes. Though multi cellular organisms can survive in a variety of environmental conditions but then also their survival is difficult than any unicellular organism.
Explanation:
Much energy is demanded within a short period in a sprint as opposed to long-distance that mainly demands stamina. During sprints, therefore, the energy demands by the muscles my outpace the supply by energy because oxygen is not reaching fast enough for aerobic cellular respiration. This is why sprinting cannot be sustained for long without accumulation of lactic acid in muscles – due to glycolysis metabolisms being the main source of energy.
IN long substance however, the runner does not sprint the entire marathon but run at sustainable speeds allowing the energy demands by the muscles to be met by the more effective aerobic respiration
