Lesson notes

Learning Objectives

Indicator: B9.1.2.1.2

By the end of the lesson, learners can:

Identify the four specialised cells of dicotyledonous plants (epidermal, guard, cambium, and xylem cells) by their names and distinctive shapes when shown charts, videos, or diagrams.
State at least one primary function for each of the four specialised cells studied (epidermal, guard, cambium, and xylem).
Match each specialised cell to the tissue or part of the plant where it is found (e.g., xylem in roots and stems, guard cells in the leaf epidermis).
Explain in their own words how at least two of these specialised cells work together to keep a dicotyledonous plant alive (e.g., xylem and epidermal cells in water transport and protection).
Use at least one digital source (video, website, or e-book) to find and record an additional fact about plant specialised cells, building on skills from the previous lesson on specialised cell formation.

Curriculum details

Strand: Diversity of Matter (Strand 1)
Sub-strand: Living Cells (1.2)
Content standard: B9.1.2.1 - Demonstrate knowledge of specialist cells of dicotyledonous plants and humans, their formation and functions for the existence of the plants and humans
Indicator: B9.1.2.1.2 - Examine the functions of specialised cells in dicotyledonous plants such as epidermal, guard cells, cambium, xylem in relation to the existence of the plants
Suggested placement: Term 1, Week 4 (Week 4 of the year)
Our suggestion, laid out in curriculum order across three terms of twelve weeks. NaCCA does not fix the week, so follow your school's scheme of learning.

Exemplars (from the NaCCA curriculum)

1. Observe specialised dicotyledonous plant cells such as epidermal, guard cells, cambium, xylem from videos and charts and identify them by their names and shapes.
2. Search from books and the internet for information on the functions of the specialised cells of dicotyledonous plants and how they relate to the existence of the plants.
