Of the three morphological types of leaves, how would you classify the pine leaf? Explain. The
tiny plants that form along the edges of leaves of plants such as Kalanchoe are genetically
identical to the parent. Why? What is the significance of having mom stomata on the lower side
of a leaf than on the upper side in dicots? What is/are the advantage(s) of having a palisade layer
on the upper surface of dicot leaves? Discuss the basic structural differences between the leaves
of C_3 and C_4 plants. Determine if each of the following statements is true or false. In the
leaves of dicotyledons, the stomata are arranged in parallel rows. Most of the photosynthesis of
the leaf takes place in the spongy parenchyma. The protective layer of the abscission zone
becomes the leaf scar. Cactus spines form from modified stems.
Solution
4.Pines belong to the order Pinales, family Pinaceae and the genus pinus. Usually they have 4
types of leaves. Siblings will have 4 to 20 whorl of cotyledons, the anger plants develop small
leaves which are long single and arranged spirally on the shoot. Later after 6 months they grow
into scaly leaves vichare arranged like Juvenile leaves they are usually non photosynthetic and
brown in colour the adult leaves or needles or green and are arranged in bundles. Classification
of pines is based on the characters of leaf ,seed and cone. Sub genus strobus and Ducampopinus
both contain one fibro vascular bundles per leaf where as the sub genus Pinus contains two
fibrovascular bundles per leaf.
5. Basically kalanchoe plant is an example of asexual reproduction. In these plants the new ones
developed vegetatively known as bulbils in phylloclade margins whivh eventually drop off and
developed roots in the soil. As a result the newly developed plans are identical to mother plant
genetically.
6. The arrangement of leaves is the reason behind the presence of most tomato on the lower
epidermis in dicotyledons as the leaves are directly exposed to sunlight you to the horizontal
arrangement you are stomata present on the upper epidermis to prevent excess water loss.
7. The layer just below the upper epidermis is called palisade layer chloroplast are present in this
layer so this layer is mainly responsible for carrying out photosynthesis. As the light energy is
received mostly by the upper part of leaf the pslisade tissue is present in upper surface of dicot
leaves.
8. Basic structural differences between C3 and C4 plant leaves:
C3 plants :the leaves do not possess kranz anatomy, chloroplast have only one type, mesophyll
cells carry out photosynthesis, photosynthesis can be performed only when the stomata are open.
C3 plants considered less efficient in photosynthesis. the bundle sheath cells usually do not
contain chloroplast.
C4 plants :the leaves have kranzs anatomy ,chloroplasts are of dimorphic ,their bundle sheaths
contain prominent chloroplasts, mesophyll cells can do initial fixation, they can perform
photosynthesis even when the s.
ANATOMY OF DICOT AND MONOCOT LEAVES.pptxRASHMI M G
A leaf is a principal appendage of the stem of a vascular plant, usually borne laterally aboveground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the shoot system
A leaf is made up of three main parts: the blade (lamina), the petiole (leaf stalk), and the stipules. The blade is the flat, green surface of the leaf, and is made up of veins and veinlets. The petiole is a long, thin stalk that connects the blade to the stem. The stipules are two small leaf-like structures located on either side of the petiole base.

Plant leaves help to sustain life on earth as they generate food for both plant and animal life. The leaf is the site of photosynthesis in plants. Photosynthesis is the process of absorbing energy from sunlight and using it to produce food in the form of sugars. Leaves make it possible for plants to fulfill their role as primary producers in food chains. Not only do leaves make food, but they also generate oxygen during photosynthesis and are major contributors to the cycle of carbon and oxygen in the environment. Leaves are a part of the plant shoot system, which also includes stems and flowers.
1. Plant leaves are very important structures as they help to maintain life on earth by generating food (sugars) via photosynthesis.
2. Leaves can have different shapes and sizes. The basic components of leaves in flowering plants (angiosperms) include the blade, the petiole, and the stipules.
3. There are three main tissues found in leaves: the epidermis, the mesophyll, as well as vascular tissue. Each tissue type is composed of layers of cells.
In addition to performing photosynthesis, some plants have other highly specialized functions. Examples include carnivorous plants that can 'eat' insects.
4. Some animals, like the Indian leafwing butterfly, mimic leaves to camouflage themselves from predators.
Plants are an essential part of the ecosystem. Every life on the earth is directly or indirectly dependent on plants. Among the different parts of a plant, the leaf is the most essential.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

3. NODALANATOMY
Shoots consists of stems bearing
leaves.
The point where the leaf attached to
the stem called Node. ( site of
attachment of leaves to the stem )
The distance between two nodes on
the shoot is called Vegetative
Internodes.
4. LEAF TRACES
Leaves must have access to a source of water and
essential minerals.
This transport of substances takes place in primary
vascular connections between the stem vascular system
and the base of leaves called Leaf traces.
Leaf traces are composed of protoxylem, metaxylem,
protophloem and metaphloem.
6. LEAF GAP
The continuity of the cylinder of primary vascular tissue
is broken immediately above the position of outward
divergence of leaf trace, leaving a discontinuity is called
Leaf Gap.
Since, these leaf gaps doesn’t affect vascular system.
Lateral connectivity between tissues on top and bottom of
the leaf gap is formed, since vascular system connectivity
is breaked due to leaf gaps.
9. PHYLLOTAXY
“Phyllotaxis” or “Phyllotaxy” is the arrangement of
leaves on a stem.
The word phyllotaxy is derived from ancient Greek word.
( Phyllo means leaf and taxis means arrangements )
Phyllotaxy in mature plants is directly related to the
position & size of leaf primordia produced on apical
meristems of varying size and shape.
10. TYPES OF PHYLLOTAXY
Based on the number of leaves and arrangement of leaves
from the nodes, the phyllotaxy has various types.
I. Alternate
II. Opposite
III. Whorled
11. Alternate Phyllotaxy
When only one leaf develops at each node. Eg: Brassica
campestris
Based on the position of leaves at after particular number
of leaves, alternate phyllotaxy is further subdivided into
two.
a) Distichous
b) Tristichous
12. A) Distichous:
When 3rd leaf comes over the first one. Eg; Grasses.
B) Tristichous:
When 4th leaf comes over the first one. Eg; Cypres.
13. Opposite Phyllotaxy
When a pair of leaves are present just opposite to each
other at each node, eg; Calotropis.
There are two types in opposite phyllotaxy.
A. Opposite Deccusate
B. Opposite Superposed
A) Oppposite Decussate:
When two successive pairs of leaves occur at right angle
to each other, eg; Psidium gujava.
15. Whorled Phyllotaxy
When more than two leaves are arranged in the form of
whorl at each node, the phyllotaxy is called Whorled. Eg;
Hydrilla verticillata, Nerium etc.,
