leaf

stem

lower part of capsule

uper part of capsule

Transpiration takes place from:

steam

leaves

all parts of the plants

only arial part of the plant

The size of the stomates in a leaf is controlled by the

xylem cells

phloem cells

guard cels

heterotrophic cells

Why cambium is considerd a lateral meristem?

Because it gives rise to lateral branches

Because it increase the birth of the plant

Because it increase the length of the plant

Because it increase the height and the diameter of the plant

in respiration pyruvic acid is

Formed only when oxygen is available

product of glycolysis

broken doun into carbon fragment

a result of protein breakdown

Opning of stomata is due to:

turgidity of guard cells
