Anatomy of Root

Q.

Root hairs are present in the outermost layer of root called.

1. dermis

2. epidermis

3. cortex

4. xylem

Q. Assertion: Pinus seeds germinate and establish in the presence of mycorrhizae.
Reason: Fungal filaments form network around the young roots/penetrate the root and increase the amount of water absorption in these plants.

1. Both A and R are correct and R is the correct explanation of A.
2. Both A and R are correct but R is not the correct explanation of A.
3. Only A is correct.
4. Both A and R are incorrect.

Q.

Is root hair a cell?

Q. The correct sequence of path of water from the soil into the xylem of the root is:

1. Soil-epiblema-endodermis-cortex-pericycle-xylem
2. Soil-epiblema-cortex-endodermis-pericycle-protoxylem-metaxylem
3. Soil-epiblema-cortex-endodermis-pericycle-metaxylem-protoxylem
4. Soil-cortex-epiblema-pericycle-metaxylem-protoxylem

Q. Casparian strips are present in the ___________of root and have depositions of______

1. endodermis, chitin
2. endodermis, suberin
3. pericycle, suberin
4. epiblema, suberin

Q.

The path of water from the soil in to the xylem of the root is:

1. Soil - root hair - endodermis - cortex - pericycle - xylem

2. Soil - root hair - cortex - endodermis - pericycle - protoxylem - metaxylem

3. Soil -root hair -cortex - endodermis - pericycle - metaxylem - protoxylem

4. Soil - cortex - root hair - pericycle - metaxylem - protoxylem

Q.

Root hairs occur in the zone of:

1. Cell division

2. Cell elongation

3. Cell maturation

4. Root cap

Q. The correct sequence of path of water from the soil into the xylem of the root is:

1. Soil-epiblema-endodermis-cortex-pericycle-xylem
2. Soil-epiblema-cortex-endodermis-pericycle-protoxylem-metaxylem
3. Soil-epiblema-cortex-endodermis-pericycle-metaxylem-protoxylem
4. Soil-cortex-epiblema-pericycle-metaxylem-protoxylem

Q.

Absorption of water along with mineral solutes mostly take place through maturation region of the root tip.

1. True

2. False
