Elaborate the evolutionary change in the pattern of heart among the vertebrates? |
| Answer» The heart of fish has two chambers. This means there is no separate circulation for oxygenated and deoxygenated blood. There is separation of two chambers in the atrium of amphibians. This has further evolved for partial separation of ventricle as well in reptiles. Finally in birds there is complete separation of oxygenated and deoxygenated blood circulation due to advent of four chambers in the heart. Mammal heart is the most developed having the most efficient double circulatory system with four chambers and separation of two blood streams. | |

Plant kingdom |
|
Answer» Features of Plant Kingdom:\tPlants are autotrophic, except for some carnivorous plants. They trap photo energy from sunlight and convert it to chemical energy through photosynthesis. Because of these plants are the main channel for supplying energy in the food chain on earth.\tReproduction in plants can be by any of the following modes: Vegetative or Asexual, and Sexual Reproduction.\tThe plant cell is unique because of the presence of cell wall and large vacuoles. Green parts of plant contain chlorophyll, which helps them in trapping the photo energy.\tSizes of plants can vary from microscopic to a very large tree. Plants are mainly divided into Algae, Bryophytes, Pteridophytes, Gymnosperms and Angiosperms.\t\tLower plants, like algae and bryophytes, have thalloid structure, while higher plants, like gymnosperms and angiosperms, have clearly defined roots and stems.\tIn higher plants root gives a means to anchor in the soil and helps the plant in taking minerals and water from the soil. Green leaves on the stem help them in photosynthesis.\tMost of the plant grow as a result of photosynthesis. After photosynthesis, extra food is utilized to facilitate growth.\tUsually in higher plants growth is unlimited and some taller trees can live a life of more than 1000 years.\tBeing the main carbon fixation agents, plants are very important for the whole ecology.\tThe whole food basket for humans is being filled by the plant kingdom. Even animal products, like milk and poultry, are indirect results of plants carbon fixation.\tPlants supply raw materials for a majority of economic activities. Wood for furniture and building materials come from plants. The whole paper industry is dependent on plant kingdom. Think of a life if there was no paper and you may understand the larger impact on human civilization.\tAngiosperms have special organs, called flower, to bear sexual parts. Flowers are helpful tool in facilitating variations and further evolution of the plant kingdom. Join telegram group *biology notes for neet* U can see notes with pictures |

Leptotene |
| Answer» The leptotene stage, also known as the leptonema, is the first of five substages of prophase I in meiosis. The term leptonema derives from Greek words meaning "thin threads".
