BISC 101 - Plant Exam With Questions And Veried Answers
Already Graded A
autotrophs ("self feeders") - Correct Answer>>>use light energy to drive the
synthesis of organic molecules from CO2 and water
primary growth by the apical meristem (lengthens roots) - Correct Answer>>>cell
division, cell elongation, cell differentiation (vascular, ground and dermal cells, and
development of extensive root hair system and lateral roots)
root cap - Correct Answer>>>protects delicate apical meristem, secretes
polysaccharide slime (mucigel), detect gravity and determine direction of growth
root hairs - Correct Answer>>>increase SA of root for absorption of water and
minerals
parenchyma cells - Correct Answer>>>thin flexible primary walls, large central
vacuoles; metabolic/storage functions; primary site for photosynthesis
collenchyma cells - Correct Answer>>>thicker primary cell walls, in strands that
support parts of plant shoots (e.g "strings" of celery)
Photosynthesis - Correct Answer>>>harnesses sunlight to make carbohydrate (sugar)
Chloroplasts - Correct Answer>>>the site of photosynthesis in plants
endergonic reaction - Correct Answer>>>requires energy to react
Photosynthesis as a REDOX process - Correct Answer>>>- plants take in CO2 and
H2O, and with the aid of sunlight (energy) synthesis carbohydrate (glucose) and
release O2
- carbon is reduced
- oxygen is oxidized
- endergonic
, Cell wall - Correct Answer>>>- provides mechanical strength
- consists of rods or fibres of cellulose in a matrix of other polysaccharides and
proteins
Plasmodesmata - Correct Answer>>>connects cells through cell walls
central vacuole - Correct Answer>>>storage, waste breakdown
chloroplasts - Correct Answer>>>- site of photosynthesis
- have double membrane
- have fluid filled stroma
- has hundreds of membrane-bound thylakoids (= 3rd membrane system)
