Specialisation of cells in animals leads to the formation of

• Tissues and organs

• Stem cells and organs

• Stem cells and tissues

Which row has the correct information about stem cells?

• Found in Embryos, Specialised Cells, Cannot self-renew

• Found in Tissues, specialised cells, can self-renew

• Found in Embryos, Unspecialised cells, can self renew

• Found in tissues, unspecialised cells, cannot self-renew

Stem cells are

• Specialised cells which can divide to produce new stem cells

• Specialised cells which are unable to divide to produce new stem cells

• Non-specialised cells which can divide to produce new stem cells

• Non-specialised cells which are unable to divide to produce new stem cells.

Which of the following shows terms listed in order of increasing level of organisation in a multicellular organism?

• Organ → Tissue → System

• Organ → System → Tissue

• Tissue → System → Organ

• Tissue → Organ → System

Which of the following does NOT involve mitosis?

• Synthesis of protiens

• Growth of Tissue

• Maintenance of the diploid chromosome compliment

The Diagram shows a cell at four different stages of mitosis. The correct order for mitosis is...

• 1,3,2,4

• 2,3,4,1

• 3,2,1,4

• 4,1,2,3

The Diagram shows the percentage of cells dividing in four areas of a root cap. Which graph represents the number of cells dividing in this root?

• A

• B

• C

• D

The diagram represents a cell in an early stage of mitosis. State the number of chromosomes present in this cell.

The diagram shows a cell in the early stages of mitosis. State how many chromosomes will be present in each of the two cells produced by the process.

Cell specialisation can lead to the formation of tissues. Give an example of a specialised cell and describe how it is specialised to carry out its function.
