Solutions
two chlorophylls found in green plants are - Answer chlorophyll a (chl a) and
chlorophyll b (chl b)
Accessory pigments - Answer carotenoids, phycobilins
- light energy is also absorbed by them
chlorophyll a - Answer can participate directly in light reactions converting solar energy
to chemical energy
chlorophyll b and carotenoids - Answer can absorb light energy and transfer it
to chlorophyll a which initiates the light reaction
- chlorophyll b has slightly diff structure to a so it can absorb light at
different wavelengths
- carotenoids also absorb light at diff wave lengths increasing the spectrum
of wavelengths able to be absorbed and drive photosynthesis
Dermal tissue system has what cells? - Answer Epidermal cells
Vascular Tissue system has what type of cells? - Answer Xylem, phloem
Ground tissue has what types of cells? - Answer Parenchyma, collenchyma,
sclerenchyma
- within this matrix there is a series of vascular bundles
- located between vascular and dermal tissue
,Primary tissue grows via which growth regions? - Answer Meristems
stem - Answer - main stalk of plant
- produces buds and leaves
- forms a connection between roots and leaves
- conducts water and inorganic chemicals to all parts of the plant
Outer epidermis (dermal tissue system) is protected by what? - Answer cuticle
what gives rise to secondary tissue growth? - Answer the cambium
(sandwiched between the xylem and phloem cells)
monocots and eudicots - Answer Monocot
- one cotyledon in seed
- root xylem and phloem in a ring
- vascular bundles scattered in stem/ complex arrangement
- floral parts usually in multiples of three
- fibrous root system
Eudicots
- two cotyledons
- veins usually branched
- vascular bundles arranged in ring
- floral parts usually in multiples of four or five
- taproot usually present
, parenchyma cells - Answer cortex
- storage
- spherical round, thin
- most abundant
- has large vacuole so needs to be flexible for shrinking and growing
- alive and maturity
- stores food/ energy glucose
- photosynthesis
stele - Answer vascular tissue of root and stem
- the central part of the root or stem containing the tissues derived from the
procambium. These include vascular tissue, in some cases ground tissue (pith) and
a pericycle, which, if present, defines the outermost boundary of the stele.
collenchyma cells - Answer cortex
- long skinny cells
- provide support/ strong
- celery string
- support for surrounding tissues
- support to stay straight up
- alive
- irregularly shaped walls (thickness)
sclerenchyma cells - Answer cortex
- dead at maturity
- two types
1. fiber cells= more flexible
