Primary Cells and Tissues Flashcards
Ground tissue important for photosynthesis, food storage, and wound healing
Parenchyma
Photosynthetic ground tissue
Chlorenchyma
Tissues that aren’t dermal or vascular, three types
Ground tissue
Ground tissue that helps plants float
Aerenchyma
Interior of the leaf, made up of ground tissue
Mesophyll
Ground tissue, living at maturity, provides support for rapidly growing parts of the plant
Collenchyma
Collenchyma
Ground tissue, living at maturity, provides support for rapidly growing parts of the plant
Ground tissue that’s dead at maturity, thick and rigid cell wall, main structural support of plants
Sclerenchyma
Long and slender sub-type of ground tissue that supports vascular tissues
Fibers
Fibers
Long and slender sub-type of ground tissue that supports vascular tissues
Short, fat, variably shaped sub-type of ground tissue, occurring in small groups
Sclerids
Sclerids
Short, fat, variably shaped sub-type of ground tissue, occurring in small groups
Plant tissue that protects and absorbs nutrients/water
Dermal tissue
Fatty substance that protects epidermis
Cutin
Wax on top of cuticle, found on plants in very dry environments
Epicuticular wax
Dermal tissue, generally 1 cell thick, generally no chloroplasts
Epidermal tissue
Epidermal Cells
Dermal tissue, generally 1 cell thick, generally no chloroplasts
A pore found in the epidermis for gas exchange
Stomate/Stomata(p.)
Specialized parenchyma cells that regulate stomate opening and closing
Guard cells
Stoma is this two parts of the stomate
Guard cell and pore
Source of the K+ and H20 that open and close stomate
Subsidiary cell
Signals guard-cell receptors to close
Abscisic Acid (ABA)
Small, specialized epidermal outgrowths
Trichomes
Trichome “house” for mites that eat fungal spores
Domatia
Tissue type that functions in long-distance transport
Vascular tissue
Vascular tissue that transports water and nutrients up from roots
Xylem
Sub-type of xylem, longer and thinner and evolved earlier
Tracheids
Tracheids
Sub-type of xylem, longer and thinner and evolved earlier
Sub-type of xylem, fatter and barrel-shapes with large perforation plates
Vessel elements
Vessel elements
Sub-type of xylem, fatter and barrel-shapes with large perforation plates
A break in the chain of xylem
Cavitation
First xylem to develop, stretchier
Protoxylem
Second xylem to develop, wider vessels, more rigid
Metaxylem
Xylem from vascular cambium, forms wood
Secondary xylem
Meristematic tissue responsible for growth of secondary vascular tissues
Vascular cambium
Vascular tissue that conducts sugars and other products downward from leaves
Phloem
Phloem subtype that transports sugars, have very few organelles
Sieve elements
Phloem subtype that supports main phloem cells by providing for most of their metabolic needs
Companion cells
Initial phloem to develop in areas of rapid growth
Protophloem
Second phloem to develop
Metaphloem
Phloem that develops from vascular cambium; makes bark
Secondary phloem
Vascular tissue that includes both xylem and phloem as well as supporting and protective tissues
Vascular bundle
