Fixation
Nitrogen is converted from atmospheric nitrogen (N2) into usable forms, such as NO2-, in a process known as fixation. The majority of nitrogen is fixed by bacteria, most of which are symbiotic with plants. Recently fixed ammonia is then converted to biologically useful forms by specialized bacteria
Answer:
chemical change.
Explanation:
There are two types of changes in matter: physical change and chemical change.
physical change- it is a change in matter that alters only its physical properties or its physical appearance. This type of change is reversible. For example- freezing of water, the water turns into solid ice and it can be reversed by melting the ice.
chemical change- it is a change in matter that alter its chemical and thus its physical properties. Most chemical changes are irreversible. for example- burning of paper, results in black soot and ashes- Thus changing both physical and chemical properties.
Answer:
1) pollen grain (A), stigma (B), pollen tube (C), Ovary (D)
The pollen grain is a male reproductive part while ovary is the female reproductive part.
2) When a pollen grain lands on the stigma of a flower, a pollen tube begins to grow. It grows through the style until it reaches an ovule inside the ovary.
3) The pollen tube is a tube that transports the male gamete cells from the pollen grains to the ovule (female gamete) inside the ovary.
The nucleus of the pollen passes along the pollen tube and fuses with the nucleus of the ovule. This process is called fertilisation.
4) After the fertilisation, female parts of the flower develop into fruit and ovules become seeds.
