What does it mean when a plant adapts?
It grows on the rainforest floor or under water.
It changes itself to fit in better with its environment.
It grows giant leaves and has very bright flowers.

Why do plants adapt to their environments?
in order to give the surrounding animals and people enough food to survive
in order to get the water and sunlight they need to survive in a harsh environment
in order to block sunlight from the floors of the ocean and the rainforest
in order to grow very tall and to become as bright and colorful as they can
How do underwater plants adapt to their surroundings?
They have flexible leaves and stems.
They have an air space in their stems.
They have floating seeds.
They have very bright colors.
Why do some plants in the rainforest have bright flowers and grow close to the ground?
to repel any extra rainfall
to get as much sunlight on their leaves as possible
to keep animals and people away from them

How do fossils form

a dead organism becomes buried in sediment
All of the above
Which of the following is most likely to become preserved as a fossil?
a leaf
a worm
jelly fish
clam shell
Explain why there are no fossils of many early forms of life
Early forms of life where too soft to form fossils
Early forms of life were very, very small so finding fossilised remains is very difficult.
Most dead organisms do not form fossils they decay
All of the above
When a fossil forms, which of the following events happens last?
Water flows into the cast and minerals in the water replace the animals bones.
Sediment covers the dead animals bones.
The bones decay.
The layers of sediment compacts the animals bones.

The bones are made up of minerals.
The bones are those of the dinosaur itself.
The bones were formed from mud that hardened.
