- Hold the dissected plant material between your index finger and thumb, while keeping the edge of the razor perpendicular to the longitudinal axis of the plant. Slice it into thin sections.
- Using the edge of the blade, shift these sections into a watch glass with the help of a brush.

What does transverse section mean in biology?
trans·verse sec·tion.
a cross section obtained by slicing, actually or through imaging techniques
, the body or any part of the body structure, in a horizontal plane, that is, a plane that intersects the longitudinal axis at a right angle.
What is transverse section of leaf?
The
shape of the leaf or
leaflet (phyllodes are treated as leaves), in cross-section, at or around the lamina mid-point. Note that in dried material, this character may be obscured by the pressing/drying process, particularly amongst taxa with soft (herbaceous) leaves.
How do monocots grow in girth?
Anatomy Of Monocot Stems
They
cannot increase in girth
by adding lateral layers of cells as in conifers and woody dicots. Instead, they have scattered vascular bundles composed of xylem and phloem tissue. Each bundle is surrounded by a ring of cells called a bundle sheath.
What is ts of a stem?
Stem: A
Tranverse section
(T.S.) of the stem of Selaginella is somewhat circular in outline and shows the following structures: (i) Epidermis: It is the outer most covering layer comprising of a single cell in thickness. The cells of the epidermis are without hairs and stomata.
What is ts of monocot stem?
T.S or the transverse section of stem is
the internal tissues of monocot stem
and you can find four regions in these T.S tissues such as epidermis, hypodermis, ground tissues and vascular bundles. On the other part, vascular bundles contain xylem and phloem.
What is the meaning of transverse view?
1 :
acting, lying, or being across
: set crosswise. 2 : made at right angles to the long axis of the body a transverse section.
What is the difference between longitudinal cross transverse and horizontal cuts in anatomy?
What is the difference between longitudinal cross transverse and horizontal cuts?
The sagittal plane or lateral plane
(longitudinal, anteroposterior) is a plane parallel to the sagittal suture. … The transverse plane or axial plane (horizontal) divides the body into cranial and caudal (head and tail) portions.
What is the difference between longitudinal and transverse cuts?
What is the difference between Longitudinal and Transverse Section?
Longitudinal section runs through the anterior posterior axis
, whereas the transverse section goes between lateral ends. Longitudinal sections are usually longer than transverse sections. … Longitudinal section is right-angled to the transverse section.
Is transverse the same as cross section?
Sections through or parallel to either the sagittal or coronal (also called frontal) plane are longitudinal.
A transverse section is perpendicular the anterior-posterior axis
and is also called a cross section .
What is a transverse cross section?
A transverse section is a cross-sectional part that
is achieved by cutting the body or any part of the body structure in real
or with help of imaging techniques in a horizontal plane. That plane crisscrosses the longitudinal axis at a 90-degree angle.
What is the largest area of the leaf?
Each leaf typically has a leaf blade called
the lamina
, which is also the widest part of the leaf. Some leaves are attached to the plant stem by a petiole.
What causes a plat to increase in diameter or girth?
The increase in length of the shoot and the root is referred to as primary growth, and is the result of cell division in the shoot apical meristem. Secondary growth is characterized by an increase in thickness or girth of the plant, and is caused by
cell division in the lateral meristem
.
Why does girth of stem increase?
Explanation: The increase in the girth of a stem or secondary growth takes place
due to the presence of lateral meristem, cork cambium, and vascular cambium
. Apical meristems are found on the apices / growing parts of a plant such as tips of shoots, roots, etc.
What increases the girth of a tree?
Another layer,
the cork cambium
, contributes to the expanding girth of a tree. The cork cambium is a thin layer cells that ultimately produces the bark of the tree. The bark is composed of several types of tissue produced (both toward the inside and the outside of the tree) by the cork cambium layer.
