The root that is formed from the root of the plant is called a parasya root. For example, orchids.

When the main root swells and takes the shape of a tuber, it is called Kandal root. Like- Sandhyamalti, sweet potato etc.

The root that develops from the base of the stem when the primary root is destroyed is called a bunch root. The roots of monocots are clustered roots. For example – Paddy, Wheat, Sugarcane, Bhutra, Kaun, Barley, Durbaghas, Palm, Betel nut, Onion, Garlic etc.

A root formed from an organ other than the embryonic root is called an ablative root. Like Bot, Kaya, Aswattha, Patharkuchi etc.

The permanent root that develops from the embryonic root is called main root. Dicotyledonous plants have main roots. Radishes, carrots, beets, turnips etc. are the main roots converted.

1. Main or Spatial Root: The permanent root that develops from the embryonic root is called main root. Dicotyledonous plants have main roots. Radishes, carrots, beets, turnips etc. are the main roots converted.
2. Absent root: A root formed from an organ other than the embryonic root is called an ablative root. Like Bot, Kaya, Aswattha, Patharkuchi etc.
3. Bunch root: The root that develops from the base of the stem when the primary root is destroyed is called a bunch root. The roots of monocots are clustered roots. For example – Paddy, Wheat, Sugarcane, Bhutra, Kaun, Barley, Durbaghas, Palm, Betel nut, Onion, Garlic etc.
4. Kandal root: When the main root swells and takes the shape of a tuber, it is called Kandal root. Like- Sandhyamalti, sweet potato etc.
5. Parasya root: The root that is formed from the root of the plant is called a parasya root. For example, orchids.
6. Epidermis: Epidermis is formed from the leaves of plants. For example, stone chips.
7. Rhizome: The rhizome is formed from the stem part of the plant. Such as sugarcane, bhutra etc.

Plants that grow on dead plant or animal bodies and take food from them are called Saprophytes. Eg Agaricus, Mucor, Penicillium, Saprolegnia etc.

Plants that grow on other green plants and take food from them are called parasites. For example, golden vine.

A plant that grows under the shelter of other plants but does not absorb food is called paraphyte. For example, orchids

Hard, woody and perennial plants with buds are called trees. Like- Mango, Jam, Jackfruit etc. Dr. Siddique Publications
