Human Biology ATAR Year 11 - Unit 1
Exam Questions and Answers
CELLS AND TISSUES - Correct Answers -
What is the human body comprised of? - Correct Answers -Cells, tissues and organs
within complex systems which work together to maintain life.
*What is a cell organelle? - Correct Answers -A small structure in a cell that is
surrounded by a membrane and has a specific function.
What is the function of cell organelles? - Correct Answers -They maintain life processes
and require:
- input of materials
- removal of wastes
to support the efficient functioning of the cell
How is the muscular system organised? - Correct Answers -- To maintain posture and
produce movement
- *muscle fibre contraction can be explained using the sliding filament theory
How is movement done in the body? - Correct Answers -Movement results from the
actions of paired muscles with others acting as stabilisers.
What does the skeletal framweork of the body consist of? - Correct Answers -- Bone
and cartilage which function to provide the body support, protection and movement
- This is assisted by the structure and function at the cell and tissue levels.
How are joints of skeletons categorised? - Correct Answers -- Structure
- Range of movements permitted
What is the function of the cell membrane? - Correct Answers -It seperates the interior
of the cell from its outside environment.
It allows for movement of meterials into and out of the cell.
*by osmosis, simple diffusion, facilitated diffusion, active transport and vesicular
transport (endocytosis/exocytosis)
