MERISTEMS
Has the ability to
1. Enlarge and stretch
2. Differentiate into other cells
MERISTEMS
Increase the length and girth of the plant
MERISTEMS
Building blocks of specialized plant structures.
(buds of leaves and flowers, tips of roots and shoots)
MERISTEMS
Mature cells
PERMANENT TISSUES
Non-dividing cells
PERMANENT TISSUES
Arise from meristems
PERMANENT TISSUES
Main functions include the conduction of water, minerals, and nutrition.
Provides support, protection, and helps in photosynthesis.
PERMANENT TISSUES
MERISTEM BASED ON ORIGIN
- P__________ M.
- P______.
- S_________ M.
- Primordial M.
- Primary.
- Secondary M.
Earliest meristematic tissue
Embryonic origin
1.PRIMORDIAL MERISTEM
Three kinds of primary meristems.
P__________ - develops into epidermis
P___________ - develops into primary xylem and phloem
G_______meristem - develops into the cortex and the pith.
Three kinds of primary meristems.
Protoderm
Procambium
Ground meristem
It is also called a lateral meristem.
There are two types of lateral meristem.
- V_______ C__________- produces secondary xylem and secondary phloem.
- C____ C_______- produces the periderm which replaces the epidermis.
There are two types of lateral meristem.
- vascular cambium
- cork cambium
MERISTEM BASE ON LOCATION
- A_____ M.
- I_________ M.
- L_______ M.
- Apical M.
- Intercalary M.
- Lateral M.
Located in the tips of shoots and roots
- APICAL MERISTEM
Increase height of the plants.
- APICAL MERISTEM
Located in the leaves and internodes
- INTERCALARY MERISTEM
Increase the length of the internode
- INTERCALARY MERISTEM
Located in the stems and roots on the lateral side.
- LATERAL MERISTEM
Increases the thickness of the plant
- LATERAL MERISTEM
Vascular and cork cambium
- LATERAL MERISTEM
MERISTEM BASE ON FUNCTION
- P_______
- P____________
- G_______ M___________
- Protoderm
- Procambium
- Ground Meristem
is the outer Meristematic Tissue that protects from injuries.
PROTODERM
is the inner Meristematic Tissue that helps in the transportation of nutrients and water.
PROCAMBIUM
helps in the development of ground tissue, endodermis, pericycle and cortex.
GROUND MERISTEM
PERMANENT TISSUE
- D______
- G______
- V_______
- Dermal
- Ground
- Vascular
DERMAL TISSUE
1. E______
2. P__________
- Epidermis
- Periderm
A single layer of closely packed parenchymatous cells.
EPIDERMIS
Contains…
1. Stomata
2. Cuticle
EPIDERMIS
regulate water intake and help in gaseous exchange.
STOMATA
Reduces water loss through the epidermis.
CUTICLE
Multilayered and consists of nonliving cells that cover the outside of stems and roots to protect the plant.
PERIDERM
Replaces epidermis in plants that undergo secondary growth
PERIDERM
Living cells
Oval or round shape
Thin walled
Parenchyma
Small nucleus
Have vacuole
Found in all parts of the plant
Parenchyma
Involved in photosynthesis, secretion, food storage, and other activities of plant life
Parenchyma
Living cells
Elongated/ long cells
Thick- walled cells
Flexible
collenchyma
Found mostly in the cortex of stems and leaves
collenchyma
Primary supporting tissues of herbaceous plants
collenchyma
Dead cells
Thick- walled
Various shapes
Rigid and non stretchable
sclerenchyma
Provide mechanical support and rigidity to the plan
sclerenchyma
Found in non growing parts (bark or mature stems)
sclerenchyma
2 vascular tissue
1. x_______
2. P_____
xylem
phloem
Hollow vessel
Non living cells
XYLEM
Transports water and minerals from roots to leaves.
XYLEM
one way vessel
XYLEM
2 parts of xylem
- t_______
- v______ element
tracheid
vessel element
vascular tissue:
Complex tissue
With many parts
PHLOEM
It is a group of undifferentiated cells that form into plants specialized structure.
Meristematic tissue
It is a tissue that fills in the soft parts of the plant.
Ground Tissue
Found in mature plants
Permanent Tissue
It is a tissue that transports water and nutrients all throughout the plants body.
vascular Tissue
Protective covering of plants.
Dermal Tissue
