- Structures of
monocotyledonous and
dicotyledonous plants
- Monocotyledon
- One cotyledons
- Leaf veins = parrallel
- Roots = fibrous adventitious
- Floral organs = X3
- Stem vascular
arrangement = scattered
- Pollen = single furrow/pore
- Pollen =3 furrows/pores
- One cotyledons
- Dicotyledon
- Two cotyledons
- Leaf veins = reticulated
- Roots = lateral branches
- Floral organs
= X 4 or X 5
- Stem vascular
arrangement =
in a ring
- Two cotyledons
- Monocotyledon
- Distribution of tissues in the leaf and
their function
- Upper Epidermis
- Function: secretes cuticle to
create way outer boundary
- Distribution: on top of leaves where
light intensity and heat the greatest
- Function: secretes cuticle to
create way outer boundary
- Palisade Mesophyll
- Function: cells contain
many chloroplasts
- Distribution: upper half of leaf
where light intensity greatest
- Function: cells contain
many chloroplasts
- Vascular Tissue
- Function: Transport of water (xylem) and products
of photosynthesis (phloem)
- Distribution: found in middle of leaf
- Function: Transport of water (xylem) and products
of photosynthesis (phloem)
- Spongy Mesophyll
- Function: gas exchange (loosely packed cells with spaces)
- Distribution: lower half of leaf, near stomatal pores
- Function: gas exchange (loosely packed cells with spaces)
- Upper Epidermis
- Modification of roots, stems and leaves
- Storage roots
