non-glandular hairs
purely protective
Zhoupi
secondary protection organization
Dicotyledonous plant roots and stems undergo secondary growth to form
composition

mechanical organization
cell wall thickening
type
chlamydia
Primary wall with uneven thickening
Living cells, containing chloroplasts, capable of meristemization
Classification
True (corner) pachycornis
Thickened at the four corners
Plate-like (sheet-like) chlenchyma tissue
Tangential wall thickening, planar thickening
lacunar chlenchyma
Having intercellular spaces and thickening of intercellular spaces
sclerenchyma
Important supporting tissue in plants
With uniformly thickened secondary walls across the board
Protoplasts that have no life after maturity are dead cells
Classified according to form
fiber
Long cells, thickened with cellulose and lignin
Division of occurrence locations in plants
Identification basis
wood fiber
Angiosperm xylem, with lignified secondary walls
xylem outer fibers (bast fiber)
separating fibers
Inlaid crystal fiber
crystal sheath fiber
branched fibers
stone cells
The shape of stone cells varies greatly and is an important basis for identification of traditional Chinese medicines.
septate stone cells
mosaic cells
spar cells
secretory tissue
Classification based on the location of secretory cells expelling secretions
external secretory tissue
Distributed on the surface of the plant body, secretions are excreted from the body
type
glandular hairs
nectaries
internal secretory tissue
Distributed in plants, secretions also accumulate in the body
Differentiated according to different morphological structures and secretions
secretory cells
secretory chamber
Divided according to formation process and structure
lytic secretory cavity
The secretory cells themselves rupture and dissolve, forming a chamber containing secretions in the body Cells around the chamber are often fragmented and incomplete
split secretory cavity
Secretory cells separate from each other and the intercellular spaces gradually expand Secretory cells are not destroyed and completely surround the chamber
secretory tract
Epithelial Cells
According to different storage secretions
Resin Road
oil pipe
mucous duct or mucous duct
milk ducts
Classification based on development and structure
Unknotted milk duct
knotted milk duct
Living cells, found in the cytoplasm
conducting tissue
Tissue that transports water and various nutrients in plants
ferns, gymnosperms, angiosperms
Classified according to transported substances
xylem
catheter
The main water transport tissue of angiosperms
A series of long tubular or cylindrical duct-shaped molecules connected to a tubular structure
Different textures depending on thickening

Threaded conduit
Ladder conduit
Reticulated conduit
perforated conduit
Tracheid
Water-transporting tissues of most ferns and gymnosperms

Phloem
Sieve cells
Transport photosynthesis in ferns and gymnosperms
single living cell
There are no specialized sieve plates, only sieve domains present on the side walls
companion cell
Sieve tube
Phloem of angiosperms and
Each tubular cell is called a sieve tube molecule
Features
