Anatomy In Flower Flashcards
Different organ of plant are similar in their internal structure
True or false( ncert pg no 84
Different organ in plants show difference in their internal structure
A tissue is group of cells always a common funtion
True or false
A tissue is group of cells usually a common funtion (pg84)
Most common type of tissue found in all plants
Parenchyma
Monocot and dicot thave seen to be anatomically different
True or false
True
Axillary meristem form branch or flower because of
Floridein starch
Both apical and intercalary meristem contribute to formation of primary plant body
(True or false)
True
Lateral meristem are
Cyndrical meristem
Lateral meristem is responsible for
Secondary tissue
Specific region of apical meristem produce
Dermal , fundamental ,vascular or conducting tissue
Parenchyma has. Thick cell wall
T/F
False has thin cell wall made up of cellulose and intercellular space is present or may not be present
Collenchyma cell assimilates
Food when they contain chloroplast
Mechanical strength to young plant and petiole of stem and mechanical strength to organ provided by
Collenchyma and sclerenchyma resp
Sclerenchyma divided on the basis of
Form , origin , development structure
Gynosperm lack vessel or Tracheld
vessel
Trached have inner layer of cell wall made up
Cellulose
Presence of vessel are characteristics of
Angiosperm
Radaol conduction of water takes place by
Parenchymatous cell
A- a mature sieve tube is control by nucleus of companion cell
Region- it possesses peripheral cytoplasm and largevacuole but lack nucles
Both are correct and correct explanation
A- the companion cell help in mantaing the pressure gradient of sevie tube element
R- they are connected by pith field present between their longitudinal walls
Both are correct and correct explanation
Bast fibre
Phleom fibre
Narrow sive tube
Protoxylem
On which basis tissue system is divided
On the basis of their structure and location
Epidermal cell made up of elongated and loosely packed arrangewhich form continuous layer
No compactly pack has parenchyma cell and it has no intercellular space
Trichome are secretory or absorper
Secretory
Conjiont open and conjiont clesd in divide on the basis of
Cambium persent and absent and if cambium present it form secdary tissue and not then not form
In dicot root pericycle has
Thicked wall parenchymatous cell and pericycle undergoes dedefferentiation and form cambium and lateral root
Endodermis acts as
Check point which decide type and quantity
Water enter from root hair to cortex by
Aqua porin
Dicot pith small and conspicuous and monocot root pith inconspicuous and we’ll developed
Wrong as monocot conspicuous and dicot inconspicuous
Monot root do not undergoes
Secondary growth
Some tissue inthe inner side of endodermis such as pericycle pith vascular bundle constitue stele
Wrong all tissue not some tissue
In dicot stem the cell are arrange in single layer between endodermis and pericycle constitue cortex
Wrong arrange in multiple layer
In dicot stem and monocot stem hypodermis consist of sclerenchyma and collenchyma respectively
Wrong monocot has sclerenchyma and dicot has collenchyma (which has rounded parenchyma cells)
Medullary rays consist of which type of cell and funtion
Radial parenchymatous cell and funtion is origin of interfascicular and cambium and store food
ring like structure are characteristics of
Dicot stem
scattered vascular bundearin
Monocot stem and phloem parenchyma are absent
Adaxial means upper surface and abaxial means lower surface of the leaf has conspicuous cuticle
Right but in dicot leaf
Isobilsteral leafs means
It is in monocot and same number of stomata in upper adaxial and lower abaxial surface
Veins vary in thickness in the parallel venition of dicot leaf
Wrong reticullate vennation
In grass which cells certain modified
Adaxial epidermal cell modify into large,empty , colourless ,cells called buliform cells
The parallel venition in monocot leaf reflected in near similar sizes of vascular bundles expect in main veins means midrib
True
