A. Organized Body Made of One or More Cells - Kirby C.

Gymnosperms have many organisms, like phloem is a living tissue that carries nutrients and its in vascular plants. Xylem is just like phloem but it supports the tissue and protect and cambium
And gymnosperms have true roots,stems,and leaves. They also have stiff, woody stems and cones.
Conifers are best known of the gymnosperms many conifers have special leaves called needles.

B. Obtain and Use Energy - Kirby C.

Gymnosperms get thier energy from carbon dioxide and it release oxygen for the people so they get fresh air. Then they the use water from the soil so they get minerals then thier main source for energy is the sun.

C. Reproduce-Daniel W.

Sporophyte plants produce both male Male and female cones, then within the cones male and female gametophyte structures. Mature female cones consist of a spiral of wood made scales on a small stem. At the base of each scale is an ovule which contains megaspores. Microspores are produced in male cones, which then cells transform into small grains of pollen. Then in spring pollen gametophytes. The male gametophytes produce male reproductive cells (sperm cells) and the female gametophytes produce female reproductive cells (eggs). Wind blows the sperm cells to the eggs creating new seeds. This process is released from the male cones and carried to the ovule, Once a seed develops in the ovule they are released from the cone and grow into a sporophyte plant. called pollination.

D. Grow and Develop - Nick Z.

Germinated seed then it change's into a seedling which get's grass then becomes a mature tree which gets a trunk branches and bark and gets stronger as a adult.
The more sun, the bigger it will get, but it will have to rain sometimes.It cannot survive without water cause it will dry up and die.

E. Respond to Stimuli-Daniel W.

Gymnosperms respond in many ways. Ginkos (an example of a gymnosperms) shed their leaves in the fall, unlike cycads and conifers. In some cases gymnosperms grow towards and away from stimuli. Gymnosperms also grow and respond to touch, light, and gravity.



(Picture beside: A Ginko tree losing it's leaves in fall do to change in climate.)

F. Exchange Gases with the Environment - Nick Z.

They exchange gasses with the enviroment through respiration and photosynthesis. Respiration is when raw materials enter the plant through microscopic openings called stomata. The raw materials are turned into food and the food provides energy for the plant. Waste gasses in the form of water vapor exit the plant through the stomata.
