THE INGREDIENTS FOR LIFE

1) Liquid water 2) Chemical building blocks like carbon, oxygen, hydrogen and nitrogen3) An energy sourceIn one corner of the Solar System, life abounds.
From the frozen lakes in Antarctica to the boiling ocean-floor springs of the Pacific, planet Earth is teeming with life. But these diverse locations all share some common ground. They all contain the essential ingredients needed to create life.1) Liquid waterBiologists studying primitive organisms all agree on one thing. Liquid water is absolutely essential for life to evolve and survive. The search for life on other worlds is a search for places where water can exist in liquid form. But why is water so precious? For life to evolve, simple chemicals must combine to form more complex ones. Many chemicals dissolve in water allowing them to mix together and react Liquid water is the right temperature for chemical reactions to happen Many chemicals have parts which are attracted to water and parts which are repelled by it. These forces also help reactions happen 2) Chemical building blocksCarbon is important because of its ability to form long chain-like molecules. Carbon chains form the backbone of organic molecules. Hydrogen and oxygen can both bond with carbon in lots of different ways. These two elements make up water molecules. So if water is present, hydrogen and oxygen will already be there. Like hydrogen and oxygen, nitrogen can also combine with carbon in lots of different ways. Large molecules made from carbon, hydrogen, oxygen and nitrogen also tend to be very stable. Sulphur, phosphorus, sodium, potassium, magnesium, calcium, manganese, iron, cobalt, copper and zinc are all needed for life as we know it on Earth.3) An energy source
All chemical reactions need an energy source to drive them.
On Earth, most primitive animals and plants get their energy by absorbing ultra-violet light from the Sun. This is called 'photosynthesis'. Humans and other animals get their energy by eating plants, or other animals. So all animals ultimately rely on energy from the Sun to live.Stage 2: combining these ingredients to make lifeLife finds a wayUntil recently, it was thought that life couldn't exist anywhere that was shaded from the Sun's light. However, scientists have recently discovered organisms living deep beneath the ocean. These organisms absorb energy directly from chemicals in the water around them.

Flower specialization and pollination

Each flower has a specific design which best encourages the transfer of its pollen. Cleistogamous flowers are self pollinated, after which, they may or may not open. Many Viola and some Salvia species are known to have these types of flowers.
Entomophilous flowers attract and use insects, bats, birds or other animals to transfer pollen from one flower to the next. Flowers commonly have glands called nectaries on their various parts that attract these animals. Some flowers have patterns, called nectar guides, that show pollinators where to look for nectar. Flowers also attract pollinators by scent and color. Still other flowers use mimicry to attract pollinators. Some species of orchids, for example, produce flowers resembling female bees in color, shape, and scent. Flowers are also specialized in shape and have an arrangement of the stamens that ensures that pollen grains are transferred to the bodies of the pollinator when it lands in search of its attractant (such as nectar, pollen, or a mate). In pursuing this attractant from many flowers of the same species, the pollinator transfers pollen to the stigmas—arranged with equally pointed precision—of all of the flowers it visits. Anemophilous flowers use the wind to move pollen from one flower to the next, examples include the grasses, Birch trees, Ragweed and Maples. They have no need to attract pollinators and therefore tend not to be "showy" flowers. Male and female reproductive organs are generally found in separate flowers, the male flowers having a number of long filaments terminating in exposed stamens, and the female flowers having long, feather-like stigmas. Whereas the pollen of entomophilous flowers tends to be large-grained, sticky, and rich in protein (another "reward" for pollinators), anemophilous flower pollen is usually small-grained, very light, and of little nutritional value to insects.
