Frequently asked questions
What is Topic 2: Cells and control?
Cell division, growth, stem cells, the brain, nerves and the eye. 13 lessons in 2 subtopics.
What is mitosis?
Mitosis is the cell division process that creates two cells genetically identical to each other and to the original parent cell. The Mitosis and Cell Division Process notes cover this in full.
What is a stem cell?
A stem cell is an undifferentiated cell, one that hasn't specialised yet. The What are stem cells and where are they found? notes cover this in full.
What are the stages of the cell cycle?
The cell cycle has three main stages. The The Cell Cycle and Preparation for Division notes cover this in full.
What is a synapse?
A synapse is the microscopic gap between two neurones where nerve impulses are transmitted using chemical messengers called neurotransmitters. The Reflex Actions and the Reflex Arc notes cover this in full.
What is a stimulus?
A stimulus is a change in the environment that triggers a response. The How the Nervous System Works notes cover this in full.
What is long-sightedness?
Long-sightedness (hyperopia) is a vision defect where near objects appear blurry because light rays would focus behind the retina, while distant objects can be seen more clearly. The Vision Problems and Corrections notes cover this in full.
What is the difference between rods and cones?
Rods and cones are the two receptor cells in the retina. The Structure of the Eye notes cover this in full.
What is the difference between mitosis and meiosis?
Mitosis creates identical cells for growth and repair, while meiosis creates genetically different gametes, or sex cells, for reproduction. The Mitosis and Cell Division Process notes cover this in full.
