Phloem
Phloem (Product Code: SCL483/0161) is a prepared slide of phloem, the vascular tissue that moves sugars and other food materials from the leaves to the parts of a plant that use or store them, used to teach translocation. Secondary school and college students use it to identify sieve tubes and their companion cells, on clear borosilicate glass stored in a white plastic box. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as practical biology lab equipment for schools.

What Is the Phloem Slide Used For?
In flowering plants phloem consists of sieve tube elements, companion cells, phloem parenchyma and phloem fibres. The sieve tube elements are joined end to end through perforated sieve plates and lose their nucleus as they mature, relying on the narrow, densely filled companion cells beside them. On this slide students practise telling the thin-walled conducting cells from the thicker-walled fibres, and learn why phloem, unlike xylem, must stay alive to work.
Among high school biology lab equipment, the phloem slide is best used with a xylem slide or a stem section, so a class can locate both tissues within a vascular bundle. Ask learners to mark the direction of sugar movement from a leaf (source) to a root or fruit (sink) on their drawings. Wipe off fingerprints with lens tissue before viewing, because smudges blur the fine sieve-plate detail.

Recommended companions for a phloem and translocation lesson:
- Xylem — the water-conducting partner tissue in every vascular bundle.
- Ts Of Dicot Stem — shows phloem in position within the stem’s vascular bundles.
- Prepared Microscope Slide Set – Transport In Plants — broadens the lesson to the whole transport topic.
- Immersion Oil, 25ml — for oil-immersion objectives when finer cell detail is needed.
- Compound Microscope — the standard instrument for examining the slide.

Frequently Asked Questions
What are the components of phloem seen on the Phloem slide?
Phloem consists of sieve tube elements, companion cells, phloem parenchyma and phloem fibres. On the Phloem slide students mainly look for the wide sieve tubes, the small dense companion cells beside them and the thicker-walled fibres.
How can students recognise sieve tubes on the Phloem slide?
Look for wide, thin-walled cells arranged in rows, with small, dense companion cells alongside and, where the cut passes through one, a perforated sieve plate across the end wall. These are the key features students label on the Phloem slide.
Does phloem carry food only downwards?
No. Food moves from where it is made or stored (source) to where it is needed (sink), so the direction can be upwards or downwards. The Phloem slide shows the cells through which this translocation takes place.
Is an oil-immersion objective needed for the Phloem slide?
Not for general identification. A standard high-power objective shows the main cell types on the Phloem slide; oil immersion only helps if you want to study fine sieve-plate detail, and immersion oil is then applied to the slide.
Who supplies the Phloem slide?
The Phloem slide is supplied by Jain Scientific Equipments Private Limited, trading as ScienceLab from Ambala, Haryana, India. The CIN and GSTIN needed for vendor registration are given in the Supplier section, and other documents can be requested with your quotation.
Is bulk supply of the Phloem slide possible?
Yes. We quote the Phloem slide in bulk for schools, colleges and distributors across India and international markets. Mention the product code SCL483/0161, your quantity and whether the xylem slide should be included in the same quotation.
