anatomy

large empty colourless cells of adaxial epidermis along the viens of grass leaves are

• guard cells

• bundlesheath cell

• buliform cells

• lenticels

phloem in gymnosperm lacks

• albuminous cell and sieve cell

• seive tubes only

• companion cells only

• both sieve tube and companion cells

secondary phloem and xylem in dicot stem is produced by

• apical meristem

• vascular meristem

• phelliogen

• axillary meristem

caspatian strips occurs in

• epidermis

• pericycle

• cortex

• endodermis

plant having little or no secondary growth are

• grasses

• highly durable

• conducts water and mineral efficiently

• comprise dead elements with highly lignified cells

cortex is region found between

• endodermis and pith

• endodermis vascular bundle

• epidermis and stele

• pericycle and endodermis

specialised epidermal cells surrounded guard cells are called

• complementary cells

• subsidiary cells

• bulliform cells

• lenticels
