Lesson 3 Flashcards
Chemical reaction in plants
Photosynthesis
Requirements in photosynthesis
Sunlight, Water, Carbon Dioxide, Oxygen, Photosynthetic machinery of plant (chloroplast)
Important reactions
Light dependent and dark (light independent)
When plants are subjected to high light intensity, closing the stomata of plants
Photorespiration
Categories of plants
C3, C4, CAM
Basic Physiological Process in plants
Evapotranspiration, Photosynthesis, Transpiration, Mineral uptake, Response to environmental stimuli, Metabolic activities, Translocation
Phenotype / Yield formula
P= Genotype + Environment + (G×E)
Plant system formula
PS = R + S (TRANSITION REGION IS IN BETWEEN THEM)
Why roots grow towardd the center of the earth
Gravitophrism
Why shoot grows against the center of earth
Phototrophism
3 functions if roots
Anchorage, Nutrient and minerals water uptake, For propagation
2 Distinguishing factors of stem
NODE AND INTERNODE
2 functions of stem
Provide structure and support, Passage of materials
_____ passes through xylem
Water
______ passes throguh phloem
Food and nutrients
Responsible for shoot and root growth
Oot and shoot apical meristem
Allows faster rate of cell division
Meristem
Photosynthesis location flow chart
Leaves»_space; Mesophyll»_space; Chloroplast»_space; Chlorophyll
Provides shiny rough appearance of leaves
Cuticle
1st cover of layer in lants
Upper epidermis
Entry point of oxygen and co2
Stomata
Type of mesophyll with Highest volume of chloroplast
Palisade mesophyll
Lower epidermis
Contains most number of stomata
