Lesson Title: Organs, Tissues and Cells: what is the difference?
B2.2 animal and plant organs :lesson 2
Learning Outcomes
(linking to Bloom’s Taxonomy)
Objective WALT:to understand that multicellular organisms
develop systems for exchanging materials; during
development cells differentiate t o perform different
functions.
Outcome WILF:
1. ALL Describe organisation in large organisms giving
examples in plant and animals
2. MOST Explain what cell differentiation is giving examples of
differentiated plant and animals cells
3. SOME Explain why large organisms need different systems
to survive.
ENGAGE
spot the difference- Pupils
could write down initial ideas
individually, then share
objectives and then ask them
to reflect/improve on their
initial thoughts and write a
summary piece of the
discussion.

WALT: To understand that multicellular organisms develop systems for
exchanging materials; during development cells differentiate to perform different
functions.
WILF :
ALL/ GRADE C Describe organisation in large organisms giving examples in plant
and animals
MOST/ GRADE B Explain what cell differentiation is giving examples of
differentiated plant and animals cells
SOME GRADE A Explain why large organisms need different systems to survive.
A* students can elaborate on the details within their answer.
Spot the structural differences
between humans and amoeba?
Why do they occur?
Spot the difference
A model answer. What grade would you give it?
The most significant difference between the two
organisms is size. The amoeba is single celled. Amoeba
can therefore exchange materials such as food, oxygen,
and waste with the outside easily as all the cell
membrane is in contact with the outside. Humans are
multicellular and therefore in humans cells have
differentiated to become specialised to carry out a
particular function. Cells of the same type are organised
into tissues, different tissues then combine to form organs
and organs work together to form organ systems.
To reach a higher grade we need more examples.
Organ system eg the
digestive system
Organ- eg stomach
1
In the stomach
1. muscular tissue, to
churn the contents
2. glandular tissue, to
produce digestive
juices
3. epithelial tissue, to
cover the outside and
the inside of the
stomach.
A tissue is a group of cells with similar
structure and function. Examples of tissues
include:
■ muscular tissue, which can contract to
bring about movement
■ glandular tissue, which can produce
substances such as enzymes and hormones
■ epithelial tissue, which covers some
parts of the body.

What is the question?
1. Cell, tissue, organ, system.- list how are multicelluar organisms organised,
smallest to largest.
2. Differentiation. What term describes when cells become specialised for a
particular function?
3. Mesophyll, epidermal, xylem. Name 3 tissues in a plant.
4. Glandular tissue. What tissue releases enzymes in the stomach?
5. Churns contents of the stomach. What is the function of muscular tissue?
