Cotyledon
* Most cotyledons emerge from germinate seeds
* Some cotyledons absorb nutrients.
* Some cotyledons contain compounds
  - toxic compounds
* Some cotyledons have butterfly shapes
  - distinctive shapes
  - provide nutrients
* also become yellow, with some reddening of the petioles of young leaves
  - store considerable quantity of neem oil
* appear as bumps on the proembryo and the embryo elongates.
* are bean-shaped, thick, dark green above and light green below
  - kidney-shaped and smooth
  - lanceolate with rounded tips and smooth on both surfaces
* are linear and hairless
  - in shape
  - linear, long and smooth
  - long and waxy, as well as narrow and tapering at each end
  - often different in appearance from subsequent and adult leaves
  - ovate to round
  - primitive leaves inside the seed
  - round to spatulate, glabrous and fleshy
  - round, thick and large with a purple hypocotyl
* are seed leafs
  - small-sized, with long caulicles
  - smooth and green
  - spatulate with three large veins
* are the first leaves of the embryonic plant
  - produced by plants
  - pair of leaves to emerge
  - site of primary infection
* are thick and oval to spatula-shaped
  - spatulate with grooved petioles
* are thick, fleshy, lanceolate, and fairly large
  - long and narrow
  - unifoliate, and are small relative to subsequent leaves
* are without hairs but the first true leaves have hairs and a grayish appearance
* begin to form as bumps on the embryo.
* communicate their demand for sucrose to the seed coat through cell turgor signals.
* connate into a tube enclosing the plumule.
* have a slight notch at the tip
  - parallel margins and rounded tips
* leaves growth stage of normal sugar beet.
* look like Acer rubrum leaves.
* ovate to heart-shaped
  - spatulate and scurfy on the lower surface
* remain within seed coat.
* store food.
* swell to show that the Endosperm is filled with nourishment.

Dense foliage
* protects fruits from sun scald.
* provides habitats
  - shelter

### plant part | foliage:

Frond
* Most fronds arise from stems
  - underground stems
  - contain water
* Most fronds develop buds
  - little buds
  - float on surfaces
* Most fronds grow from stems
  - sporangiums
  - have mass
* Most fronds remain grind rhizomes
* Some fronds absorb nutrients
  - arise from rhizomes
* Some fronds contain buds
  - develop ferns
  - grow feet
* Some fronds have duckweeds
  - roots
  - spores
  - meet underground rhizomes
* Some fronds produce fronds
  - survive for months
* Try using the feathery fronds attached to the bulb as a herb.
* also arise from the rhizome.
* are a type of plant found in the plantae kingdom
  - big leaves such as on a fern
  - commonly monocots due to the parallel structure of the veins in the leaves
  - deciduous in colder climates and evergreen in milder climates
  - kind of the same as tendrils, really
  - large leaves that usually have many divisions
  - leaves on ferns
  - light green and turn gold yellow before going dormant for the winter
  - slightly dimorphic, with the fertile fronds standing more erect than sterile fronds
  - the branch-like pieces that extend from the plant, covered in leaves
  - vine-like structures growing out from the stipe
* are, strictly speaking, elaborate compound leaves, attached to the stem by a petiole.
  - upright then arch with age
* have a characteristic ridge along the egde of the receptacles
  - narrow segments with long spreading crests
* includes leaf shapes
  - sections
* make good insulators, and they have the added advantage of repelling water.
* pinnate to nearly or fully bipinnate.
* produce plantlets which can be removed and planted.
* remain fronds
* resemble shiny dragon scales.
* spring from a central, slowly expanding crown.
* tend to die back.
* turn brown at the ends when humidity is too low
