Which of the following is/are true? I. A measure of how much water is present in comparison with the solute molecules in the same volume of solution known as diffusion gradient II. The region found above the region of cell division can be seen in different young roots because of the presence of numerous root hairs that increase absorption. III. The meristematic region is has cells that elongate several times their original length and push the root tip through the soil. IV. The meristematic region is the growing apex of the root

Which of the following statements are true for root endodermis?I. Endodermal cells constitute the innermost layer of root cortex and surrond the vascular cylinder (xylem and phloem). II. Endodermal wall is covered with waxy layer of casparian strip which blocks apoplastic transfer of minerals.III. Due to presence of casparian strip, water and minerals can only eneter the vascular cylinder if they will be able to cross the plasma membrane of an endodermal cell.
Discuss which pathway permits the passage of most solutes and water inside the roots? Which pathway allows the entry of most of the water and some of the solutes inside the root tissue? Explain how the Casparian strip creates a barrier for substance moving through this pathway and how it is circumvented.

Researchers studying plant growth designed an experiment to test the effect of caffeine on the growth of onion roots. They hypothesized that caffeine-a stimulant-would increase the rate of root growth. They immersed the bottom of a group of onion bulbs in a solution of 1 mM caffeine and that of the other group of onion bulbs in distilled water. Then they measured the root length of both treated or experimental and untreated or control groups of onion bulbs. This was repeated for a total of five trials. The results from their experiments are illus- trated in the table below.

Determine the collective true-false status of the statements using the choices below. I. After soil water crosses a root’s epidermis, it seeps into parenchyma that forms the root’s region of cortex until it reaches the vascular cylinder.; II. In a typical eudicot root, the vascular cylinder divides ground tissue into regions of pith and cortex.; III. By contrast, the vascular cylinder in a typical monocot root contains very little pith or none at all.; IV. Water and substances dissolved in it must pass through the endodermis of a root’s vascular cylinder before entering the xylem for distribution to the rest of the plant. Only two (2) statements are true. None of the statements is true. Only one (1) statement is true. Only three (3) statements are true. All statements are true.
When farmers apply too much fertilizer to the ground, the solute concentration is higher in the soil than it is in the roots. Explain how this would affect plants. And place these structures in the order that water passes through them during transpiration: endodermis, root cortex, root hair, spongy mesophyll, stomata, and xylem. -Thank you!
Determine the collective true-false status of the statements using the choices below. I. In most eudicot leaves, large veins branch into a network of minor veins.; II. A leaf’s lower surface usually has fewer stomata than the upper surface.; III. A leaf’s upper surface typically receives the most direct sunlight may have a thicker cuticle than the lower surface.; IV. Epidermal cells secrete a translucent, waxy cuticle that slows water loss. None of the statements is true. All statements are true. Only three (3) statements are true. Only one (1) statement is true. Only two (2) statements are true.
