Class 11 Biology Chapter 14 Respiration in Plants: Important Topics

The method by which cells get chemical energy by the consumption of oxygen and the liberating of carbon dioxide is called respiration. Plants do require oxygen to respire, the process in return gives out carbon dioxide. Unlike humans and animals, plants do not possess any specialized structures for the exchange of gases, however, they do possess stomata (found in leaves) and lenticels (found in stems) actively involved in the gaseous exchange. Leaves, stems, and plant roots respire at a low pace compared to humans and animals.

Cellular Respiration

Cellular respiration is a set of metabolic reactions taking place inside the cells to convert biochemical energy that is obtained from the food into a chemical compound called adenosine triphosphate (ATP).

Respiratory Quotient

The respiratory quotient(RQ) is referred to as the ratio of the volume of carbon dioxide evolved to the volume of oxygen consumed in the process of respiration. It can also be defined as the respiratory ratio, which is dependant on the type of respiratory substrate utilized during respiration.

Read the following passage and answer the questions that follow:
India is one of the megadiverse countries housing around 8·1 per cent of global species diversity, although its land area is only 2·4 per cent of the world’s land area. Many of the species are highly threatened due to human activities like deforestation, mining and habitat fragmentation. Laws like Wildlife (Protection) Act, 1972 were enacted by the Government of India to preserve our biological wealth. Various conservation measures are being implemented to save the threatened species. The following bar graph shows the number of species conserved under different biodiversity conservation methods.

Which other methods shown in the diagram are opposite to the one identified by you in question ? How are these two conservation approaches different?
(c) Write two features of Biodiversity hotspots.
(c) To which category do sacred groves belong and how do they help in bio-conservation?
