Cellular respiration is a process that takes place inside the cells where energy is released by the breakdown of glucose molecules. The process can be conveniently divided into two categories based on the usage of oxygen, namely aerobic and anaerobic respiration.

Aerobic Respiration Anaerobic Respiration
Oxygen is present when this form of respiration takes place. Oxygen is absent when this form of respiration takes place.
Gases are exchanged in this form of respiration. Gases are not exchanged in this form of respiration.
It can be found in the cytoplasm and the mitochondria. It can be found only in the cytoplasm.
Glucose breaks down into carbon dioxide and water. Glucose breaks down into ethyl alcohol, carbon dioxide and energy.
All higher organisms such as mammals have this type of respiration. Lower organisms such as bacteria and yeast use this type. In other organisms, it occurs during heavy activities.

That is the thing that transfer from one generation to the next generation from parents to the baby

Yogita Ingle 3 years, 9 months ago

Genetics is a branch of biology which explains the transmission of body characteristics both, similarities and differences, from parents to the offspring. The groundwork on which heredity stands is known as inheritance. It is defined as the procedure by which characteristics are handed down from one generation to the other. Gregor Johann Mendel is known as the “Father of Modern Genetics” for his discoveries on the basic principles of heredity.

For sexual reproduction to take place

Yogita Ingle 4 years, 9 months ago

The significance of meiosis is given below:-
(i) Formation of gametes – Meiosis forms gametes that are essential for sexual reproduction.
(ii) Genetic information – It switches on the genetic information for the development of gametes or gametophytes and switches off the sporophytic information.
(iii) Maintenance of chromosome number – Meiosis maintains the fixed number of chromosomes in sexually reproducing organisms by halving the same. It is essential since the chromosome number becomes double after fertilisation.
(iv) Assortment of chromosomes – In meiosis paternal and maternal chromosomes assort independently. It causes reshuffling of chromosomes and the traits controlled by them. The variations help the breeders in improving the races of useful plants and animals.
(v) Crossing over – It introduces new combination of traits or variations.
(vi) Mutations – Chromosomal and genomic mutations can take place by irregularities of meiotic divisions. Some of these mutations are useful to the organism and are perpetuated by natural selection.
