Grade 10 Biology: Lesson 8

Transpiration

Transpiration

________ helps move the water up the xylem by evaporating water out of the leaves.

Sap transport

________ in Phloem Vessels allows for nutrients to reach the various tissues in the plant.

Transports Sugars

________ produced by Photosynthesis from the Leaves to the rest of the plant.

Cohesion

________ and Adhesion help to drag the water molecules up the Xylem Vessels of the plant, however, the roots also help to push the water up the plant.

Transports Water

________ and dissolved minerals from the soil to the leaves.

Photosynthesis

After ________ has occurred in the leaves the sugars must be transported to the rest of the plant to be used as energy.

surface area

Root hairs help to increase the ________ of the roots.

Sugars

As the ________ enter the Phloem Vessels the solution becomes Hypertonic and draws in water by osmosis.

Xylem

If there is a bubble in the ________ or the water freezes the Cohesion can be disrupted and only the water molecules above the break will continue upwards.

Sugars and Dissolved Minerals

Plants need a way to transport materials such as Water, ________ throughout there various tissues.

Water

________ also has the ability to attract to other molecules.

Xylem Vessels

Water transport in ________ allows for Photosynthesis and Turgor Pressure in plants.

Phloem

________ transports the sugars (and other materials) throughout the plant.

Phloem cells

________ are alive at maturity and also act as pipes within the plant.

Epidermal tissue

________ covers the root.

Turgor Pressure

________ within the roots helps to force the Xylem sap into and up the Xylem Vessels.

Xylem cells

________ are dead at maturity and act like pipes within the plant.

Vessel Elements

The sap travels up through the Tracheid's and ________ of the Xylem Vessels towards the leaves As the Xylem sap enters the Leaves the Xylem Vessels branch into veins and deliver the water and minerals to the cells of the leaves.

Xylem Vessels

The cells are linked to each other forming continuous tubes called ________.

Lesson 8

water transport in plants

The Phloem cells are linked to each other forming continuous tubes called Phloem Vessels (Note

Cells are separated from each other by Sieve Plates)

what do plants contain so they can transport materials like water, sugars and minerals?

specialized vascular tissues called xylem and phloem

what does the xylem do?

transports water and dissolved minerals from soil to help leaves

Xylem cells are ______ at maturity and act like pipes in the plant

Xylem cells are dead at maturity and act like pipes within the plant

what's it called when xylem cells are linked together?

form continuous tubes called xylem vessels

tracheid's and vessel elements are the two groups of?

xylem vessels

the porous nature of phloem cells allows what?

allows exchange of materials between Phloem cells and neighbouring tissue cells

what are phloem vessels?

they are phloem cells linked forming continuous tubes

what are the phloem vessels separated by?

sieve plates

what are the two groups of phloem vessels?

sieve tubes and companion cells

where do water and minerals enter a plant from?

from the Roots

the xylem and phloem are found at?

the core of the root

At its tip, the ___________ cells are permeable to water and water enters the root here by osmosis

At its tip, the epidermal cells are permeable to water and water enters the root here by osmosis

______ _____ help to increase the surface area of the roots

Root hairs help to increase the surface area of the roots

Although water diffuses easily across the cell membrane, ________ do not

Although water diffuses easily across the cell membrane, minerals do not

what are the minerals and water that enter the xylem called?

xylem sap

to move minerals across the cell membrane what must be used?

facilitated diffusion

Water continues to ________ into the root tissue until it reaches the xylem

Water continues to diffuse into the root tissue until it reaches the xylem

water is a ?

polar molecule

what is cohesion?

where negatively charged oxygen attracts positively charged hydrogens of another water molecule

what does cohesion do in a plant

helps drag water up xylem vessels

what is adhesion?

waters ability to attract other molecules

what does adhesion allow water molecules to do?

climb up walls of xylem vessels

_________ allows water molecules to transport through the Xylem like a chain where each water molecule is a separate link in the chain

Cohesion allows water molecules to transport through the Xylem like a chain where each water molecule is a separate link in the chain

transpiration drags water up roots as?

water evaporates out of the leaves

in bigger plants where root pressure, cohesion and adhesion don't work, what does?

transpiration

As ____________ are Actively Transported into the root it makes the root ___________ and thus brings in more water by osmosis adding more root pressure helping the Xylem Sap to move upwards

As Minerals are Actively Transported into the root it makes the root Hypertonic and thus brings in more water by osmosis adding more root pressure helping the Xylem Sap to move upwards

what does the phloem transport?

sugars and other materials through the plant

sugars entering phloem vessels creates a solution called?

called Phloem Sap and the Sap will move throughout the Phloem Vessels down a concentration gradient to the rest of the Plant tissues
