Worked Solution & Example Answer:The electronmicrograph below shows a portion of a cell - VCE - SSCE Biology - Question 1 - 2012 - Paper 1
Step 1
Name and describe the structure of X.
Answer
Name: Mitochondrion
Description: The mitochondrion is a double-membraned organelle responsible for energy production through cellular respiration. It has a smooth outer membrane and a folded inner membrane known as cristae, which increases the surface area for ATP production.
Step 2
What would you look for to determine whether a cell is from an animal or a plant?
Answer
To determine whether a cell is from an animal or a plant, I would look for the presence of a cell wall, which is characteristic of plant cells. Additionally, I would check for chloroplasts, which are present in plant cells for photosynthesis.
Step 3
Explain the consequence of this for an elderly person.
Answer
As the structures labeled Y become less efficient, an elderly person may experience reduced energy levels and stamina. This decline can lead to difficulties in physical activities and an overall decrease in metabolic functions, impacting their quality of life.
