Largest number of chloroplast is found in :
palisade tissue
spongy tissue
transfusion tissue
bundle sheath cells
A.
palisade tissue
Dorsiventral leaf of dicot plant consits of epidermis, mesophyll and vascular bundles. Mesophyll is further divided into palisade tissue and spongy tissue.
Palisade tissue is a upper layer that consists of closely arranged cells containing numerous chloroplasts. Spongy tissue consists of losely arranged cells. Most of the photosynthesis takes place in palisade tissue.
Cook cambium and vascular cambium are :
parts of secondary xylem and phloem
parts of pericycle
lateral meristems
apical meristems
Which type of meristems allow the fallen stems of cereals/ grasses to become erect?
Apical meristem
Lateral meristem
Intercalary meristem
Secondary meristem
Quiescent centre is found in root apex and acts as
permanent source of active initiates
reservoir of resistant cells
reservoir of passive cells to form new root apex if root apex is damaged/ killed
all of the above
Phytotron is :
a controlled condition chamber for tissue
leaf culture process
special culture of plants
root culture process
Growth rings are formed due to activity of :
extrastelar cambium
intrastelar cambium
interstelar cambium
both 'b' and 'c'
An open collateral bundle is one in which :
xylem and phloem are seprated by cambium;
xylem and phloem lie side by side
cambium occurs on the out side of bundle
cambium does not occur in the bundle
