ANATOMY OF FLOWERING PLANTS

In land plants, the guard cells differ from other epidermal cells in having:-

• mitochondria

• endoplasmic reticulum

• chloroplasts

• cytoskeleton

Endodermis cells are rich in

• (a) cellulose

• (b) starch grains

• (b) starch grains

• (c) fibers

In a monocot leaf

• (a) bulliform cells are absent from the epidermis

• (b) veins from a network

• (c) mesophyll is well-differentiated into palisade and spongy parenchyma

• (d) mesophyll is not differentiated into palisade and spongy parenchyma

Closed vascular bundles lack

• (a) pith

• (b) xylem

• (c) cambium

• (d) xylem vessels

Casparian strips occur in

• a) Cortex

• b) Endodermis

• c) Epidermis

• d) Pericycle

Vascular bundles in dicot stem are

• Conjoint, collateral

• Conjoint, collateral and closed

• collateral and closed

Bulliform or motor cells are present in

• Lower Epidermis of dicot leaves

• Upper Epidermis of dicot leaves

expected in a plant possessing 9 branches and

39 leaves?

• 9
