6. Which among the following is incorrect about the adventitious root system?

Adventitious roots when buried in soil grows into new roots

These roots provide additional anchoring to a plant

These are the roots that grow from parts that are other than the radicle

Adventitious roots are present in Turnip

7. Which among the following is an incorrect statement about root?

The root is covered at the end by a thimble like structure called root cap

Meristematic tissue helps in the growth of plants

Mersistematic cells when mature forms the so called growing cells

Root hairs increase the surface area which helps in increasing the levels of water absorption

8. Which among the following is incorrect about the root?

Radicle grows to form a primary root inside the soil

From the primary roots grows the secondary roots from lateral surfaces

Most of the monocotyledons adopt tap root system

Adventitious roots are present in Banyan tree

9. Which among the following is incorrect about modifications of roots with respect to food storage?

Most of the times, tap roots become swollen to store food

Radish adopts napiform to store food

Napiform is found in turnip and the root is spherical in the top and tapers in the bottom

If the root is swollen in the middle and those that tapers on both the sides are called fusiform roots

10. Which among the following is incorrect about modifications in adventitious roots for food storage?

Tuberous roots are found in plants like sweet potato

Slender roots with swollen apex are found in Dahlia

Fasciculated roots are those that have tubercles at the stem base

11. Which among the following is not correct about modifications of roots to facilitate respiration?

In some plants that grow in marshy areas, roots are modified to facilitate respiration

Pneumatophores are specialized breathing roots that help in respiration of plant that grows in marshy areas

Breathing roots are present in mango

Exchange of gases occur through lenticels in pneumatophores

12. Which among the following is incorrect about modification in roots for mechanical support?

Prop roots are those that originate from aerial branches

Prop roots are also called hanging roots

Those roots that originate from stem base that grow obliquely and penetrate into the soil are called stilt roots

Stilt roots are present in beetle

Floating roots are present in cuscuta

14. Which among the following is incorrect about the importance of the root system?

Root system helps in absorption of water and minerals from soil

In plants like mangroves, breathing roots called pneumatophores are present

Pneumatophores grow vertically upwards and exchange gases through lenticels

Plants that grow tall derive their additional mechanical support by sending pillar like woody roots called stilt roots

15. Which among the following is incorrect about roots in banyan tree?

Banyan roots have adventitious roots called prop roots that provide them with additional support

Prop roots are also called as climbing roots

Prop roots on meeting the soil form secondary and tertiary roots

Initially these start as tiny outgrowth on the branches and become woody and large

16. Which among the following is incorrect about climbing roots?

These roots originate from nodes or internodes

They help plant climb on the surface
