The path of water from the soil in to the xylem of the root is:
Soil - root hair - endodermis - cortex - pericycle - xylem
Soil - root hair - cortex - endodermis - pericycle - protoxylem - metaxylem
Soil -root hair -cortex - endodermis - pericycle - metaxylem - protoxylem
Soil - cortex - root hair - pericycle - metaxylem - protoxylem
The correct path of water is soil-root hair-cortex-endodermis-pericycle-proto xylem-metaxylem.
The following paragraph is related to absorption of water from the soil. Complete the paragraph by selecting the correct word from those given below. You may use a term only once.
__________can enter plants through entire surface of plant body. However, the bulk of water is absorbed by land plants through the __________. Root hairs are in contact with__________. These provide a large __________ for water absorption. Absorbed water is transported to the__________ and endodermis. Internal to the__________ is a single layer of pericycle. The protoxylem elements of xylem lie in __________to the pericycle. This way a direct__________ is formed for the passage of water from the root hair cells to the __________.
Epiblema of roots is equivalent to
(a) pericycle
(b) endodermis
(c) epidermis
(d) stele
Distinguish between the following.
(a) Exarch and endarch condition of protoxylem
(b) Stele and vascular bundle
(c) Protoxylem and metaxylem
(d) Interfascicular cambium and intrafascicular cambium
(e) Open and closed vascular bundles
(f) Stem hair and root hair
Rewrite the terms in correct order in logical sequence.
Cortical cells, root hair, soil water, endodermis, xylem.
