- PLANT BODY
- Formed when 2 monosaccharides
react e.g A Glucose + A Glucose =
Maltose
- Sucrose
Maltose
Lactose
- Using water we can 'undo' the
glycosidic bond and separate the
sugar into 2 monosaccharides
(hydrolisis)
- Reducing sugars
- Sucrose = glucose & fructose (
1,4 glycosidic bond)
- Using water we can 'undo' the
glycosidic bond and separate the
sugar into 2 monosaccharides
(hydrolisis)
- The C1 OH & C4 HO react to
form H20 and a C-0-C bond
(glycosidic bond)
- Called 'condensation reaction'
- Called 'condensation reaction'
- Sucrose
Maltose

- DICOTS
- vascular bundles
arranged in stars
- palmate or pinnate
- presence of wood(secondary growth)
- taproot root

- vascular bundles
arranged in rings
- parallel
- parts of 3 or
multiples of 3
- no presence of wood

- RESPONSES TO EXTERNAL
STIMULI
- Nastic response
- plant movement in response
to a stimulus,however,it is
not associated with the
direction of the stimulus
- flower petals open during the
day and close at night to
conserve heat

- PLANT CELLS
- Sclerenchyma Cells
- very thick secondary wall
with lignin
- they die after full
development of cell and
provide support for mature plants
- very thick secondary wall
with lignin
- Parenchyma Cells
- Spherical with
flattened cell walls and
and tightly packed
cells
- leaves and cells have
chloroplasts, and has
large cenral vacuoles
- Spherical with
flattened cell walls and
and tightly packed
cells
- Collenchyma Cells
- long strings thta
are pulled from
celery stock
- elongated, long strands
or cylinders that
provide support for
surrounding cells
- thick cell walls, and as the plant grows,
the thinner cell wallsexpand making
them flexible
- long strings thta
are pulled from
celery stock
- Sclerenchyma Cells

- Meristematic
- embryonic tissues that
can develop into
specialized plant cells
