Botany Slides

Quick Answer: Botany slides are prepared microscope slides of plant material, typically stained sections of roots, stems and leaves and whole mounts of algae, spores or pollen. Students view them under a compound microscope to learn plant tissues and to identify the major plant groups.

What Plant Slides Usually Cover

A plant slide set is organised around what a syllabus asks students to recognise. Transverse sections, marked T.S., cut across a stem or root and show the arrangement of vascular bundles: scattered in a monocot stem such as maize, in a ring in a dicot stem such as sunflower. Longitudinal sections, L.S., run along an organ, for example through a root tip to show the zones of cell division and elongation. Whole mounts, W.M., place a small organism or structure, such as Spirogyra or a fern prothallus, on the slide intact.

Stains make the tissues readable. Double staining with safranin and fast green is common in botanical preparations, colouring lignified xylem red and softer cellulose tissues green, so students can pick out xylem, phloem, cortex and pith without guessing. Epidermal peels show stomata and guard cells, and pollen slides show the patterned walls used in plant identification.

The listing gives neither the number of slides nor their titles, and sets vary widely, so it is worth matching the list to the course. Prepared microscope slides act as a reference that students compare with their own temporary mounts of onion epidermis or hand-cut stem sections.

Specifications

Applications

• Identifying xylem, phloem, cortex and pith in stem and root sections
• Comparing monocot and dicot anatomy in stems, roots and leaves
• Studying algae, fungi, mosses and ferns as whole mounts for classification
• Practical examinations where students identify a slide and draw labelled diagrams

Care & Handling

• Return botany slides to a slotted box after use and store the box flat, label side up.
• Remove immersion oil straight after use with lens tissue and a suitable lens cleaner, so it does not soften the mountant.
• Keep slides away from direct sunlight, which slowly fades stains such as fast green.

Why Choose LabEquip

Schools and colleges usually order plant slides to cover the tissues and plant groups in their syllabus and replace broken ones each year. LabEquip offers them within its prepared slides range, and a slide box keeps a set in order; send your syllabus list through the contact page.

Frequently Asked Questions

What do T.S., L.S. and W.M. mean on a slide label?

T.S. is a transverse section cut across the organ, L.S. is a longitudinal section cut along it, and W.M. is a whole mount, where a small organism or part is mounted intact without cutting.

How can students tell a monocot stem from a dicot stem on a slide?

In a monocot stem the vascular bundles are scattered through the ground tissue. In a dicot stem they form a ring, with cortex outside and pith in the centre, and cambium may be visible between xylem and phloem.

Why are xylem cells stained red?

Safranin binds strongly to lignin, the stiffening material in xylem walls, and colours it red. A counterstain such as fast green colours the thinner cellulose walls of phloem and cortex, so the two tissues are easy to tell apart.

Are prepared slides better than temporary mounts?

They do different jobs. Prepared slides are thin, evenly stained and permanent, so every student sees a clear reference. Temporary mounts teach the skills of sectioning, staining and mounting. Most practical courses use both.

Which magnification is needed for plant tissues?

Low power, about 40x or 100x total, shows the layout of tissues in a stem or root section. High power, about 400x, is used for single cells, stomata or pollen detail.

How should prepared slides be cleaned?

Wipe the cover glass gently with lens tissue, lightly moistened if needed. Avoid strong solvents, which can dissolve the mounting medium, and never press hard on the cover glass.
