The Vascular System Of The Flowering Plants

Functions Like Which Human System?

Vascular system

Every Cell In The Flowering Plant Body Is Near To, And Can Exchange Chemicals With The -

Roots

Absorb minerals, mineral salts, and water from soils

Xylem tissue

Must deliver water to leaves

Xylem tissue

Which Tissue Enables The Flowering Plant To Transport The Substances That Its Roots Absorb From The Soil To All Its Cells?

Xylem tissue

In Flowering Plants, Which Vascular Tissue Also Provides Each Plant With Its Primary Source Of Structural Support?

Water

According To Plant Some Physiologists, What Is The Most Common Molecule And The Most Critical Nutrient In The Xylem Sap?

Transpiration

The evaporation of water from plant surfaces

______ Through Stomata -

• Creates The Negative Pressure (“_____ Pull”) That Drives The Ascent Of Xylem Sap

• Regulates Leaf Temperature To Maintain Efficient Metabolism

o Plants Lose Heat By _______ Sweating (Plant Sweating)

o 90% Of The Water Roots Uptake Exits Plants By _______

• Water Accumulation Pressurizes Leaf Cells Which Increases Cell Size And Leaf Surface Area

• Water Is A Substrate For Photosynthesis

• Water Evaporation From The Leaf Surface Maintains Proper Leaf Temperature

Why Must The Xylem Tissue Deliver Water

(HO) Molecules To The Leaves Of The Plant?

Transpiration

Which Process Drives The Ascent Of The Xylem Sap Upwards In The Xylem Tissue?

Tracheid and vessel elements

The Xylem Sap Moves Through The Hollow Interior Of Two Cell Types That Are Like

"Pipes". What Are These Cell Types?

• Tracheid

• Vessel Element

• Sclerenchyma Cell (Fiber)

Which Cell Type(s) In Xylem Tissue Provides Structural Support For Xylem Tissue And Consequently For The Entire Plant?

Carbohydrates

All cells in flowering plants need _____

Phloem tissue (bark)

Delivers phloem sap in many directions ensuring that all cells have sucrose

• primary composition of ____ ____ is carbohydrates/sucrose

Phloem tissue

Which Tissue Enables The Flowering Plant To Transport The Carbohydrates Made In The Leaf Cells By Photosynthesis To All The Cells In Its Body?

Sink tissue with lower levels of sucrose

Phloem Tissue Transports Sucrose From

Source Tissues With High Sucrose

Concentration To -

Photosynthetic leaf

What Is An Example Of A Source Tissue In The Flowering Plant That Provides Sucrose To The Sink Tissues With Low Sucrose

Concentration?

Sucrose

What Is The Most Common Food Molecule In The Phloem Sap?

Sclerenchyma Cell (Fiber)

Which Cell Type In The Phloem Tissue Is Specialized To Provide Structural Support?

Plasmodesmata

What Enables The Cytoplasm Of Adjacent Plant Cells To Exchange Hormones To Permit Cell To Cell Communication And Consequently Coordinate Their Activities?

Intracellular Transport In Large Plant Cells

 Cytoplasmic Streaming (Cyclosis) Distributes Substances Rapidly

Within Large Plant Cells And Requires -

• Actin Filament (Microfilament) And Myosin Motor Protein Interaction

• ATP Molecules That Energize Myosin Motor Proteins
