Grade 10 Biology: Lesson 6-9 ( SA:V, specialization and organization, Gas exchange, Water transport)

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.

Woody plants

________ contain Lens- Shaped openings called Lenticels that allow for gas exchange in their stem /trunk.

Carbon dioxide

________ is taken in at night and stored as a different chemical until it is used for Photosynthesis later in the day.

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.

Animals

________ have the ability to sense and then respond to their environment by thinking and acting.

Active transport

________ moves the Auxin into the cells of the shaded side of the plant.

Photosynthesis

________ requires Carbon Dioxide which is taken into a Leaf through the Stomata.

Phototropism

________ allows the plant to maximize the amount of light that is absorbed by the leaves which in turn maximizes the amount of Photosynthesis within the leaves.

Turgor Pressure

________ is caused by the movement of water into the Central Vacuole of a plant cell.

gas exchange

Leaves are the main area for ________ in a plant.

crucial function

The Leaves of all plants perform a(n) ________ for the Plant: PHOTOSYNTHESIS.

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.

Spongy

________ and Palisade Tissues are surrounded by a thin layer of water.

Auxin

After ________ is produced in the tip of the plant it travels to the shaded side of the stem.

Charles Darwin

In 1880 ________ and his son Francis performed experiment to prove that plants will grow toward a light source.

Xylem Vessels

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

Water

________ also has the ability to attract to other molecules.

Phloem

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

Negative Gravitropism

________ occurs in the Stems of plants in which the stem will grow upwards against gravity.

Positive Gravitropism

________ occurs in the Roots of plants which the roots will grow downwards with gravity.

Phloem cells

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

sap

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

Epidermal tissue

________ covers the root.

Tissue Cells

Chloroplasts in the ________ undergo Photosynthesis, converting the Carbon Dioxide into Glucose and Oxygen.

Xylem cells

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

Gravitropism

________ is a plant growth response to Gravity (an environmental stimulus)

Vacuole swells

The ________ and pushes against the Cell Wall causing the plant cell to become swollen and more rigid.

Transpiration

________ can account for the loss of 99 % of the water absorbed by the roots of the plant.

Photosynthesis

________ occurs in the Chloroplasts of the Cells found in Leave's of plants.

Gas exchange

________ in plants: something in the air.

Turgor Pressure

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

Carbon Dioxide

________ diffuses into a leaf through Stomata.

Gas Exchange

________ is Tied to Water Loss.

Photosynthesis

________ produces Oxygen that is released out of the Leaf through the Stomata along with Water Vapour.

Carbon Dioxide

________ circulates in the spaces between the Spongy and Palisade tissues cells.

Carbon Dioxide

________ diffuses into the Spongy and Palisade Tissue Cells down a concentration gradient.

The Leaves of all plants perform a crucial function for the Plant

PHOTOSYNTHESIS

Auxins

Plant Growth Chemicals

Plant tip Partially covered by chemical soaked Agar

Plant Grew Away from the Side with the Chemical Soaked Agar

Plant tip Completely covered by Non-chemical soaked Agar

Plant Did Not Grow At All
