-the fruit falls to the ground, and organisms eat it and the seeds inside, distributing it to a new location, where it will grow into a new angiosperm (sporophyte)
Here is the life cycle of a gymnosperm;
-haploid pollen grain from the male cone attaches to the pollen tube for fertilization in the female cone (gametophyte)
-mature fruit developed from ovary to protect seeds and promote seed dispersal
-seed germinates and produces the sporophyte generation of tree

Boy is it hot over here, perfect temperature for this Eucalyptus you see to the right.
The Eucalyptus tree is an angiosperm. That means it is a seed-producing plant that is enclosed within an ovary (usually a fruit). They life cycle of an Angiosperm is as follows,
-pollen is released from the stamen of the flower(gametophyte)
-pollen attatches to the stigma
-the flower loses ist stamens and a fruit forms

Characteristics of Gymnosperms
Characteristics of Angiosperms
- They do not have an outer covering or shell around their seeds
- They do not produce flowers
- They do not produce fruits
- They are pollinated by the wind
- Their seeds develop on the surface of the reproductive structures of the plants rather than being contained in a specialized ocary
- Seeds are often found on the surfaces of cones and short stalks
Characteristics of Angiosperms
- They have flowers, which serve as reproductive organs
- Small pollen grains which are much smaller than the gametophytes. so fertilization occurs quicker
- Have stamens in flowers which produce pollen grains and carry male genetic information
- Have carpel that encloses developing seeds that may turn into fruit
- Production of endosperm, a material that forms after fertilization and serves as a highly nutritional food source for the developing seed and seedling
Eucalyptus trees are well suited to their environment. Most are evergreens, which means that they have a wonderful capability for rationing water throughout the year, which in the hot country of Australia is very important. They are single-stemmed which allows them to grow very tall and a dense crown of leaves. They can grow to be short of tall, depending on the species.
