Question

Path of water movement from soil to xylem is
(a) metaxylem – protoxylem – cortex – soil – root
hair
(b) cortex – root hair – endodermis – pericycle –
protoxylem – metaxylem
(c) soil – root hair – cortex – endodermis –
pericycle – protoxylem – metaxylem
(d) pericycle – soil – root hair – cortex –
endodermis – protoxylem – metaxylem

Answer 1

The pathway of water from soil to xylem is:

(c) soil – root hair – cortex – endodermis – pericycle – protoxylem – metaxylem

• The water from the soil goes to the root hair.

• It then goes to the cortex which is the outermost part of the stem.

• It then gets transported to the endodermis that regulates the water that gets into the plant.

• From here it goes to pericycle that is just inside the endodermis.

• After that, it goes to protoxylem which is the first formed xylem.

• At last, it goes to metaxylem which is involved majorly in the conduction of water.

Answer 2

soil – root hair – cortex – endodermis - pericycle – protoxylem – metaxylem

Explanation:

• The path of water through the root of the plants are a bit complex.

• Firstly the water is absorbed from the soil through the root hair cells.

• These root hair cells are the cells of epidermis with less thick cell wall.

• These cells then pass the water to the cortical cells.

• The water through cortical cells move via two processes - through the cells and through the intercellular spaces.

• The water then reaches the endodermis.

• Endodermis is a lignin walled cells which are water tight.

• There are passage cells in between the endodermis which are parenchymatous cells that lead the water enter inside the endodermis.

• Inside the endodermis there is a layer of thin parenchyma cells called pericycle.

• Then comes the older xylem called the protoxylem.

• Then comes the big cavity metaxylem which actually transfers the water and salts to leaves.
