Which part of the root is primarily responsible for water absorption?

    Select the correct statement

    Identify true and false statements and select the correct option from the codes given below

I.    As suction pressure increases, water absorption also increases which in turn increases the absorption of ions

II.    Absorption of ions is affected by transpiration pull

III.    Large amount of charged particles are absorbed along with absorption of water

IV.    Pressure flow hypothesis depends entirely on the existence of mechanism for loading sugars into phloem at the source region and unloading it at the sink

V.    Contents in the sieve tube move undirectionally

    Choose the correct statement regarding casparian strips

I.    It surrounds pericycle

II.    It is made up of legnosuberin

III.    It limits the pathway available to water solutes, forcing them to enter the symplast

Which one of the following is not a part of symplast?

Which one is not the job of zone of cell differentiation in roots?

    Read the following statement and choose the correct one from the codes given below

I.    The apoplastic movement of water takes place exclusively through intercellular spaces and cell wall without crossing any membrane

II.    Symplastic movement occurs from cell to cell through plasmodesmata, ., adjacent cells are connected through plasmodesmata

III.    Permeability of a membrane depends on its composition and chemical nature of the solute

IV.    Solutes present in a cell increases the free energy of the water or water potential

The term apoplast signifies

    Which part of root absorbs both water and minerals?

The Casparian strip in the endodermis is primarily made of:
