Common misconceptions
Xylem and phloem tissue are often confused. Xylem carries water and
mineral salts, while Phloem transports sugars and amino acids.
In a vascular bundle in a stem, Phloem is on the outside and Xylem is on
the inside.
Examiner's tips
1. You need to be able to give examples of tissues, organs and organ
systems in both plants and animals. A leaf is an organ made up of a
number of tissues, e.g. upper epidermis, palisade, mesophyll.
2. If you draw a diagram to support an exam answer, make sure you
refer to its in your written answer. Annotation is more likely to help
you gain extra mark.
Example of annotation
