Monocot vs Dicot LEAVES

monocot: narrower leaves w/ parallel veins

dicot: broader leaves with veins in net-like pattern

LEAVES:

Simple

Pinnately Compound

Palmately Compound

Simple: single petiole, midrib, and blade 

Pinnately Compound: leaflets attach opposite each other along the length of the rachis

Palmately Compound: leaflets attach at common center point near tip of petiole[image]

Stomata

microscopic pores that allow gas exchange to occur into and out of the leaf

[image]

Mesophyll cells

(THINK meso-middle phyll-filling)

Trichomes

epidermal hairs

Stem

Epidermis

outermost tissue

Cortex and Pith

(Dicot)

 makes up the bulk of the stem, provides support, stores synthesized carbohydrates

Veins

a vascular bundle that forms part of the conducting and supporting tissue of a leaf

STEMS:

Monocot vs Dicot

(vascular bundles)

monocots: v.b randomly scattered

dicots: v.b concentrically arranged toward the outer perimeter of the stem seperating the cortex from the pith 

[image]

Secondary Xylem

The actual wood; porous; transports water and dissolved minerals throughout the plant body

Vascular Cambium

thin layer of tissue with cells that divide and produce more xylem and phloem

Secondary phloem

carries the plant sap filled with dissolved organic molecules synthesized by the plant 

[image]

Cork Cambium

(cork and bark)

cork cambium: tissue that produces cork cells on its outer surface and phelloderm on its inner

cork: cells on the outer surface of woody stems and roots (produced by c.c)

[image]

Apical meristems

(THINK: apex= tip/very end)

both the tip of the shoot and the root

[image]

Root

anchor a plant into the soil and provide a means of  absorbing soil, nutrients, and water

Monocot VS Dicot Roots

monocot: vascular cylinder is much larger; large/open xylem cells

dicot: vascular cylinder is smaller and located in the center; xylem tissue forms recognizable cross pattern

[image]

Vascular Cylinder

composed of xylem and phloem tissues; transports body fluids or sap

[image]

Vascular Bundles

(THINK: bundle = carry)

The veins; made of xylem and phloem tissues; CARRIES a plants body fluids or sap

[image]

Xylem

vascular tissue that conducts water and minerals

Phloem

vascular tissue that conducts organic materials synthesized by the plant 

Guard Cells

(THINK: guards the stoma)

specialized cells in the epidermis that regulates the opening and closing of the stoma
