Front (Question)

Uptake of water by the root hair cell

Back (Answer)

Osmosis

Front (Question)

Water movement through the root

Back (Answer)

Osmosis Pathways

Front (Question)

Pathway where water moves cell to cell via cell to cell

Back (Answer)

Apoplast

Front (Question)

Pathway where water moves cell to cell via the cytoplasm and through plasmodesmata

Back (Answer)

Symplast

Front (Question)

Pathway where water moves trough vacuole

Back (Answer)

Vacoula

Front (Question)

Water movement up the xylem into the root and stem

Back (Answer)

Transpiration Root pressure Transpiration pull Properties of water

Front (Question)

Explain cohesion

Back (Answer)

tendency of water molecules to attract one another

Front (Question)

Explain adhesion

Back (Answer)

tendency of water molecules to be attracted to molecules of different types

Front (Question)

Water movement through the leaf

Back (Answer)

Osmosis Diffusion

#10

Front (Question)

Define transpiration

Back (Answer)

loss of water vapor from plant leaves by evaporation of water of the surfaces of mesophyll cells followed diffusion of water vapor through the stomata

#11

Front (Question)

Examples of Xerophytes in Namibia

Back (Answer)

Quiver tree Euphorbia Nara plant Baobab tree

#12

Front (Question)

How do Xerophytes reduce waterloss

Back (Answer)

Reduced stomata Sunken stomata Surface has hair to trap water vapor Smaller leaves= smaller surface area Thorns= reduce surface area Thick cuticle reflect light

#13

Front (Question)

Conditions that affects the rate of transpiration

Back (Answer)

Temperature Wind Humidity Light intensity

#14

Front (Question)

How and why does wilting occur

Back (Answer)

Rate of water loss is greater than the absorption of water Soil lacks water Shortage of water

#15

Front (Question)

Define translocation

Back (Answer)

The transport of organic molecules (sucrose+ amino acids) in the phloem from a region of production (leaves) to regions of utilization or demand in respiration or growth (flowers+ roots)

#16

Front (Question)

Translocation of pesticides

Back (Answer)

Sprayed onto the leaves, absorbed through the cuticle/ stomata into the phloem tubes. Plant sucking pest suck poisonous sap from the phloem.

#17

Front (Question)

Companion cells are:

Back (Answer)

Living cells Contain cytoplasm, a nucleus, and mitochondria Metabolically active cells

#18

Front (Question)

Phloem sieve tubes are:

Back (Answer)

Living cells contain cytoplasm and organelles Tubes are connected end to end for easy flow Organelles are at the edge to give more space for movement Have end wall with sieve plates

#19

Front (Question)

Xylem cells are:

Back (Answer)

Dead hollow cells Elongated cells arranged end to end to form tubes for transport No end wall for minimum resistance No organelles to obstruct flow Large lumen allows unrestricted flow Cellulose lining for adhesion

#20

Front (Question)

Function of the epidermis

Back (Answer)

protects the tissue

#21

Front (Question)

Function of the endodermis

Back (Answer)

regulates the passage of water

#22

Front (Question)

Function of the cortex

Back (Answer)

stores starch
