NY Regents Adapations for Transport in Plants

Simple multicellular plants , bryophytes ( such as ​ (a)   ) lack​ (b)   .

They also lack "true" roots, stems and leaves.

Therefore bryophytes/mosses accomplish intercellular transport by ​ (c)   .

• mosses
• vascular tissue
• diffusion

Higher plants, tracheophytes ( such as grasses, shrubs and trees) posses vascular tissue in their roots, stems and leaves.

Vascular tissue allows for intercellular transport.

Intracellular means ​ (a)   a cell, while intercellular means ​ (b)   cells.

Hint: ​ (c)   81 runs through Tennessee, Virginia, Pennsylvania and New York state.

• within
• between
• Interstate

Structure specialized for anchorage, nutrient storage, absorption of water and soluble salts, and for the conduction of materials to the stem are:

• Roots

• Root hairs

• Osmosis

This is elongated epidermal cells with increase the surface area of the root for the absorption of water and minerals.

• Roots

• Root hairs

• Osmosis

The diffusion of water into the cells of the roots of plants.

• Roots

• Root hairs

• Osmosis

​ (a)   is specialized transport (vascular) tissue extending from the ​ (b)  

The principal function of the xylem tissue is the conduction of water and minerals ​ (c)   in the plant.

• Xylem
• roots to the leaves
• upward

The mechanism by which water is transported through the xylem is best explained by t​ (a)   .

It involves the ​ (b)   (evaporation) of water through the ​ (c)   (pores in the leaves).

This exerts a ​ (d)   in the column of water in the xylem.

Because of the ​ (e)   properties of water, the water is drawn up from the roots.

• ranspiration pull
• transpiration
• stomates
• pulling force
• cohesion and adhesion

"Cohesion" refers to the tendency of water molecules to stick to each other, while "adhesion" describes the attraction of water molecules to other substances,

Which is correct in how water is pulled up through the xylem?

• Cohesion=water pulls water up

  Adhesion= water is attracted to the walls of the plant cell

• Adhesion=water pulls water up

  Cohesion= water is attracted to the walls of the plant cell

Xylem is the tissue that conducts water and minerals UP in the plant.

Phloem conducts organic food materials, such as sugar that is produced in the leaves due to photosynthesis.

Easy way to remember:

Xylem: dial them ​ (a)   on the phone

Phloem: ​ (b)   down
