Embibe Experts Solutions for Chapter: Transport in Plants, Exercise 1: AP EAPCET - 3 Sep 2021 Afternoon

Find correct statements from the following
$\mathrm{A})$ Protein transporters are responsible for maximum rates of transport under saturated state
$\mathrm{B})$ Translocation of substances in bulk flow requires hydrostatic pressure gradient
$\mathrm{C})$ Root pressure plays the greatest contribution for upward movement of water in tall plants
$\mathrm{D})$ Transport proteins of endodermal cells are control points for active transport of ions in two directions

The correct answer is

The salting of pickles is an example for

Assertion ($\mathrm{A}$): Pea seeds swell more on imbibition than wheat seeds.

Reason ($\mathrm{R}$): Proteins have a high imbibing capacity.

Water potential of pure water at standard temperature is ________

The magnitude of increment in water potential in a turgid cell is called ________

Assertion (A): In the apoplast pathway, water movement is ultimately symplastic in the endodermis

Reason (R): Root endodermal cells are suberized

Arrange the given events that occur in phloem for removal of water from phloem to xylem:
$\mathrm{I})$ Incoming sugars are actively transported out and removed as complex carbohydrates.
$\mathrm{II})$ Increase of water potential.
$\mathrm{III})$ Increase of hydrostatic pressure in sieve tubes.
$\mathrm{IV})$ Transport of water into sieve tubes by osmosis.
