Question 1

a pigment is the most common organic molecule in plant that absorbs light of certain wavelengths. The lights that are not absorbed are reflected.

Answer 1

Chlorophyll

Question 2

Usually it occurs in the grana of the chloroplast.

Photolysis of water happens, thus oxygen release.

ATP and NADPH is produce which are needed in the dark reaction phase.

Answer 2

Light dependent reaction

Question 3

Occurs in the stroma of the chloroplast.

It does not require light

No photolysis

Glucose is produced.

Answer 3

Light independent reaction

Question 4

are lateral outgrowth of the stem usually thin, expanded, needle like and green in color.

Answer 4

Leaves

Question 5

External Anatomy of a Leaf

– the tip of a leaf
– vein coming from the base
– arises from the midrib
– arises from the bigger veins
– found at the bottom of a leaf blade
– stalk which hold the whole leaf
– flat, thin blade of the leaves
– small paired lobes at the base
- small pair lobe on the leaflets

Answer 5

Apex – the tip of a leaf
Midrib – vein coming from the base
Veins – arises from the midrib
Veinlets – arises from the bigger veins
Base – found at the bottom of a leaf blade
Petiole – stalk which hold the whole leaf
Leaf blade – flat, thin blade of the leaves
Stipule – small paired lobes at the base
Stipel - small pair lobe on the leaflets

Question 6

– with one piece of blade or lamina

Answer 6

Simple leaf

Question 7

– the lamina consists of two or more separate parts on a common petiole.

Answer 7

Compound leaf

Question 8

The extension of the petiole to which the leaflets are attached is called

Answer 8

rachis.

Question 9

– are leaves with rachis where the leaflets are attached. Primary rachis is the continuation of the petiole in a ___

Answer 9

Pinnately Compound Leaves

Question 10

– are leaves with one rachis where leaflets arise

Answer 10

Simple pinnate leaves

Question 11

– are pinnately compound leaves in which the primary rachis
Tripinnate/ Thrice pinnate – leaves in which secondary rachis produces branchlets which bears the leaflets.

Answer 11

Bipinnate/Twice pinnate

Question 12

– are leaves in which the leaflets are attached at a common point at the tip of the petiole.

Answer 12

Palmately Compound leaves

Question 13

– compound leaves with only one leaflet
b. – with two leaflets
c. – with three leaflets
d. – with four leaflets

Answer 13

Unifoliate

b. Bifoliate – with two leaflets
c. Trifoliate – with three leaflets
d. Quadrifoliate – with four leaflets

Question 14

A. – when the veins form a network over the blade or lamina

Answer 14

Netted or Reticulate venation

Question 15

– has one main vein or midrib from which the smaller veins branched off.

Answer 15

Pinnately netted venation

Question 16

– several main veins extending from the base of the leaf.

Answer 16

Palmately netted venation

Question 17

– several main veins arising or radiating from the tip of the petiole

Answer 17

Radiately netted venation

Question 18

– Veins run parallel to each other
a. parallel to the midrib
b. parallel at acute angle/radial to the midrib
c. parallel at right angle to the midrib

Answer 18

Parallel venation
