Yes. For example every tree that is cut down you can plant a tree so the tree will grow back.
To protect and organize cells.
Answer:
they are comer than their surroundings.
Sunspots are cooler because their magnetic fields inhibit the replenishing of heat from convective flows (due to the interaction between plasma and magnetic fields). This allows them to cool radiatively. The rest of the solar surface is constantly being replenished by convective cells that reheat it.
The flower structures are identified above:
The functions are as follows.
Petal- large and brightly coloured to attract insects.
Sepal- protects the flower whilst in bud.
Stalk- supports the flower to make it easily seen by insects, and to be able to withstand the wind.
Stamen- male reproductive organ of the flower, made up of the anther and filament.
Anther- contains pollen sacs, in which pollen grains are formed. Pollen contains the male sex cells.
Filament- supports the anther.
Carpel- female reproductive organ if the flower. Made up of the stigma, style and ovary.
Stigma- sticky surface to the ovary, through which pollen tubes grow.
Style- links the stigma to the ovary through which pollen tubes grow.
Ovary- contains ovules which form into seeds when fertilised.
