Parenchyma Cells
Cells commonly present in the primary cell wall with a greater ability to divide for regeneration and wound healing

Chlorenchyma Cells
Parenchyma cells containing many chloroplasts. Mainly function for photosynthesis.
Collenchyma Cells
Thicker cells with a living cytoplasm that remain alive for a long time that occur beneath the epidermis that has a mechanical function
Sclerenchyma sclereids
A reduced form of sclerenchyma with highly thickened lignified walls that cause the grittiness in pears and the hardness of nut shells and drupes
Fibres
A form of sclerenchyma cells found in association with different tissues in roots, stems, leaves, and fruits used for textile goods, ropes, string, canvas and more
Monocot Traits
One seed leaf
Parallel veination
Flower parts in 3
Fibrous roots
Stem vascular bundles are scattered
Pollen monosulcate (single pore)
<10% woody
Dicot Traits
Two seed leaves
Netted veination
Flower parts in 4&5
Primary taproot
Stem vascular bundles in a ring

What do monocot cross sections look like compared to dicot?
Monocots look like a circle with a bunch of faces with xylem eyes, phloem skin, and bundle sheath red outline
Dicots look like a perfect circle zentangle with vascular bundles surrounding a pith. The vascular bundles have larger xylem circles and smaller phloem circles

How does a monocot root look different from a dicot root cross section?
Monocot has a huge centre while dicot have a smaller centre with a cross-shaped collection of xylems in the middle
Mature cladophyll
Cactus flattened stem
Buds
Modified broccolie shoot with a stalk, florets, and head
Bulbs
Onions with fleshy scale leaves, a basal plate, and adventitious roots
