section 3 bio Flashcards
What is a root system?
-Everything underground
-Absorbs water and minerals
what is a Shoot system?
-includes stem, leaves, buds, flowers and fruits
-contains photosynthetic organs that absorb CO2 and release O2
What are the three main types of plant tissue?
-Dermal tissue
-Ground tissue
-Vascular tissue
What is Dermal Tissue?
-found on the outside of herbaceous plants (non-woody)
-produces a cuticle
-involved with matter and gas exchange
What is Ground Tissue?
-layer beneath the epidermis
-responsible for photosynthesis and food & water storage
-makes up most of the body of the plant
What is Vascular Tissue?
-responsible for the transportation of materials
-vascular bundles are visible as the veins on the underside of a
leaf
What is xylem tissue?
-moves water and dissolved minerals
-movement from roots to stem and leaves
-transports water and nutrients for photosynthesis
What is Phloem tissue?
takes sugar down through plant
What are chloroplasts?
Used for structure
What is Photosynthesis?
6H2O + 6CO2 + energy —> C 6 H 12 O 6 + 6O2
What is cellular respiration?
C 6 H 12 O 6 + 6O2 –> 6H2O + 6CO2 + ATP
Cohesion?
the attraction of molecules for other molecules of the same kind
adhesion?
the binding or attraction between dissimilar molecules, atoms, surfaces, or substances
Root Pressure?
the hydrostatic pressure generated in the roots that help in driving the fluids and other ions from the soil in upwards directions into the plant’s vascular tissue – Xylem
Transpiration Pull
the force which aids in drawing the water upward from roots to leaves
