Frequently asked questions

What is Cell biology?

Cell biology covers Cell structure, Cell division, and Transport in cells in GCSE AQA Higher Combined Science Biology. 23 lessons in 3 subtopics.

How many chromosomes do humans have?

Human body cells have 46 chromosomes arranged in 23 pairs. The Chromosomes, DNA and Genes notes cover this in full.

What is osmosis?

Osmosis is the diffusion of water through a partially permeable membrane from a dilute solution to a concentrated solution. The Understanding Osmosis notes cover this in full.

What are specialised cells?

Specialised cells are cells that have developed specific structures and functions to carry out particular roles in multicellular organisms. The Specialised Cells in Animals notes cover this in full.

How do you calculate magnification?

Magnification is calculated with magnification = image size ÷ real size. The Magnification Calculations notes cover this in full.

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 diffusion?

Diffusion is the net movement of particles from high to low concentration. The What is diffusion and what affects its rate? notes cover this in full.

What is a gene?

A gene is a specific section of a DNA molecule that codes for a particular characteristic. The Chromosomes, DNA and Genes notes cover this in full.

What is the function of the cytoplasm?

The cytoplasm is a jelly-like substance where chemical reactions take place and in which organelles are suspended. The Comparing Animal and Plant Cell Structures notes cover this in full.
