1. Introduction
- Seed dormancy is a state in which seeds do not germinate even under favorable conditions.
- It ensures the survival of seeds by preventing premature germination.
- Dormancy helps seeds to remain viable during unfavorable environmental conditions.
2. Types of Seed Dormancy
1.
1. Introduction
- Seed germination is the process by which a dormant seed develops into a seedling.
- It is essential for the propagation and survival of plant species.
- Dormancy is a condition where a viable seed fails to germinate even under favorable conditions.
2.
1. Introduction
- After fertilization, the ovule develops into a seed, and the ovary transforms into a fruit.
- This process ensures reproduction and dispersal of flowering plants.
2.
1. Introduction to Tissue Culture
- Tissue culture is a technique of growing plant cells, tissues, or organs in a sterile and controlled environment.
- It is a form of asexual reproduction and helps in the rapid multiplication of plants.
- The process is based on the principle of totipotency, which means that a single cell can develop into a whole plant.
- It is widely used in agriculture, horticulture, and genetic research.
2.
1. Introduction to Asexual Reproduction
- Asexual reproduction is a mode of reproduction in which offspring are produced without the involvement of gametes.
- It leads to the formation of genetically identical offspring (clones).
- Vegetative propagation is a common method of asexual reproduction in plants.
- It occurs through natural and artificial methods.

1. Introduction to Biogeochemical Cycles
- Biogeochemical cycles are natural processes that recycle essential elements between the environment and organisms.
- These cycles maintain ecological balance and ensure the continuous supply of nutrients.
- The major cycles include the Carbon Cycle, Nitrogen Cycle, Phosphorus Cycle, and Water Cycle.

1. Introduction to Conservation
- Conservation of biodiversity is essential to protect species, ecosystems, and genetic resources.
- It helps maintain ecological balance and ensures sustainability of natural resources.
- Conservation methods are broadly classified into In-Situ Conservation and Ex-Situ Conservation.
2.
1. Introduction to Biodiversity
- Biodiversity refers to the variety of life forms on Earth, including plants, animals, and microorganisms.
- It is essential for maintaining ecosystem balance and providing ecological services.
- Biodiversity exists at different levels, ranging from genetic variation to entire ecosystems.
2. Levels of Biodiversity
A.
1. Introduction to Environmental Conservation
- Environmental conservation refers to protecting and preserving natural resources to maintain ecological balance.
- It involves sustainable practices, pollution control, and restoring degraded ecosystems.
- Plants play a crucial role in reducing pollution by purifying air, water, and soil.
