How were you conceived? Each one of us is the result of a single event, the meeting of male and female sex cells. Fertilisation occurs when the DNA in both egg and sperm comes together, but this doesn’t form a single nucleus. The nucleus of each parental cell is clearly visible in this microscopic image.

The planet has an exploded effect that starts from something small and opens out into beautiful colours such as pink, red, purple, blue, yellow and green. It’s got little stars that make it such a special planet. White dwarves live in this enchanted place since the last explosion. My planet is known to be the smaller of a pair of planets, they split in the explosion to create twin planets...

What are stem cells? Inside your body every time cells die, they are replaced. The continuous supply of new cells comes from stem cells. They are still flexible enough to develop into several different kinds of tissue. An embryo is a ball of the most flexible cells, which can be used to make cells for the brain, liver and lots of other organs.

This planets sensory filament is sensational! the planet has only just been discovered and believe me it is something! It looks a bit likea brain because it is round, it is brightly coloured and has a spinal cord. I couldn't believe i was the first person to discover the planet. The planets core was extraordinary, it was bigger than anything I've ever seen. I was amazed, I soon hope to go back and see my planet and hopefully I will discover more every time

A close relative of the hamster the Mongolian gerbil is a popular pet. Cells from gerbils are also useful research tools for studying cancer, ageing and infectious diseases. Within the tiny sacs of gerbil lungs are cells that look like the one pictured. GeLu (Jell-Ooo) cells make collagen and other materials that help cells gel together.

The Gerbil cell reminded me of the Sun in Spain and the red is like the background of the Moroccan flag. This planet is a very useful research tool for studying cancer.

How do sperm get around? Successful sperm owe something to the fluid in which they travel. Semen contains calcium, zinc, phosphate, citrate and various enzymes that get made and released from the prostate gland. This walnut-sized sac – here pictured in cross-section – is located below the bladder and is a key component to the male reproductive system.

Many years ago, there was a very big virus. It was very contagious and started spreading like fire. This went on for 2 months, and then suddenly there was a huge explosion and the virus finally ended. The explosion formed many different colours, such as green, yellow, orange, red, purple, blue etc. It looked like an unusual rainbow. The person who discovered this planet named it after her star sign "Cancer"...

My planet exploded and the hydrogen atoms blew up, the colours are beautiful, green, blue, red, yellow and brown. It glows like an ultra violet light. Rare cows live on it. It has stars that make it special. Gorgeous white dwarves landed on my planet after the explosion.
