Unit 2: Multicellular Life
Key Area 1: Cells, Tissues & Organs
Traffic light the following statements using red/ yellow/ green
I know that multicellular organisms are made up of specialised cells.
I know that specialised cells have adaptations suited to their function.
I can give examples of specialised cells and how they are adapted to suit
their function.
I know that tissues are made up from multiple cells of the same type.
I can give examples of tissues in the human body.
I know that organs are structures made up of a variety of tissues in order to
perform a specific function.
I can give examples of organs and the tissues that make them up.
Key Area 2: Stem Cells & Meristems
Traffic light the following statements using red/ yellow/ green
I can state that stem cells differentiate into specialised cells in animals.
I can compare the properties of embryonic stem cells with adult stem cells.
I can give examples of how stem cells could be used to treat diseases.
I can discuss ethical issues associated with stem cell use.
I can state what plant meristems are.
I can state how meristems contribute to plant growth.
Key Area 3: Control & Communication
Traffic light the following statements using red/ yellow/ green
I can state the structure and function of the Central Nervous System (CNS).
I can label the cerebrum, cerebellum and medulla and state their function.
I can describe the role of a sensory, relay and motor neurone in a reflex arc.
I can describe the reflex arc response.
I can state the role of endocrine glands, receptors and hormones.
I can explain why not all cells will be affected by the release of a hormone.
I can describe the role of hormones in regulating blood glucose
concentration
I can describe the role of the pancreas and liver in regulating blood glucose
concentration
Key Area 4: Reproduction
Traffic light the following statements using red/ yellow/ green
I can state the names of the gametes in plants.
I can state the names of the gametes in animals.
I can state where gametes are produced in plants.
I can state where gametes are produced in animals.
I can describe fertilisation in plants.
I can describe fertilisation in animals.
I can describe the difference between the terms diploid and haploid.
I can describe fertilisation in terms of haploid gametes fusing to produce a
diploid zygote.
Key Area 5: Variation & Inheritance
Traffic light the following statements using red/ yellow/ green
I can describe continuous variation and give examples.
I can describe discrete variation and give examples.
I know that examples of discrete variation are usually only controlled by one
gene.
I know that examples of continuous variation are normally controlled by
more than one gene (polygenic inheritance).
I know that offspring receive one set of chromosomes from each parent.
I understand that information held in genes on our chromosomes determines
our features.
I can use a family tree to determine an individual’s characteristics.
I know that phenotype describes an organisms characteristics, while
genotype describes the alleles it carries.
I know that heterozygous means two different alleles and homozygous
means two of the same allele.
I understand the term true-breeding.
I can carry out a monohybrid cross to determine the likely characteristics of
offspring.
I can use a test cross to determine an individual’s genotype.

movement and describe their role in water movement.

I can identify the structure and function of phloem vessels.
Animal Transport Systems
I can state that nutrients, oxygen and carbon dioxide are
transported in the blood.
I can state that red blood cells contain haemoglobin and describe
how they are specialised to carry oxygen.
