What is spore formation?

Education Journalist | Study Abroad Lead

Spore formation is a type of asexual reproduction that takes place in spores. Spores are unicellular bodies that are formed due to sexual or asexual reproduction in eukaryotic organisms including bacteria, algae, fungi, and plants.

Sporogenesis is the process through which spores are formed.
Spores are reproductive cells that form a new organism. They are mostly found in sacs that are called sporangia.
The hundreds of spores are collected in the sac by plants until it bursts.
These spores are then released into the air where they germinate to form a new plant.
Fungi such as Rhizopus, Penicillium, and Mushroom reproduce by spore formation.

Spore Formation

Examples of Spore Formation

Spores are formed in fungi on sporangium. Minute haploid spores are produced that grow into new organisms. E.g. – Penicillium.
Bacteria form another type of spore known as endospores. E.g. – Bacillus
Plants solely reproduce asexually through spore formation. They follow an alternation of the generation life cycles where haploid spores are produced by diploid sporophytes that ultimately produce haploid gametophytes. E.g. – liverworts

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?
