What is a transverse section of a 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 you take the transverse section of a leaf?

Using a sharp razor-blade (I like the “Pal” single-edge carbon steel blades) make a single cut holding the blade against the edge of the upper slide, then a second cut with the blade angled in slightly. With practice you can get sections almost as good as paraffin sections.

What are the parts of a cross section of a leaf?

Mesophyll is the inner tissue (parenchyma) of a leaf, containing many chloroplasts. Veins provides support to the leaf and veins consists of xylem and phloem vessels that transport water to leaf and the food to the rest of the plant structures.

What is meant by transverse section?

Transverse Section Definition 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. A transverse section divides the plane across the body of a plant, tissue, organ, or animal.

What is longitudinal and transverse section?

Longitudinal section: a cut that is parallel to the longest dimension of the organ or specimen. Oblique section: a cut that is at any angle between the longitudinal and transverse planes. Cross, or transverse, section: a cut that is perpendicular to the main plane of the organ or specimen.

What is section of a leaf?

Section of a leaf: chlorophyll containing outgrowth of a stem or branch; the site of photosynthesis. Spongy mesophyll: set of cells forming the central layer of a leaf. Guard cell: part of the stoma. Lower epidermis: lower layer of the leaf. Stoma: organ of the leaf that allows the exchange of gases.

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.

Where is the transverse section?

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.
