The ovary itself is usually enclosed in a flower, that part of the angiospermous plant that contains the male or female reproductive organs or both. These stomata bring in loads of CO2 and the veins move sugars around very easily. The majority of plants are capable of reproducing on their own, without any assistance from animals or other organisms. 2 What characteristics help gymnosperms adapt to life on land angiosperms? Pores for gas exchange 3. The term "sporangia" literally means "spore in a vessel," as it is a reproductive sac that contains spores . Plants can open and close their stomata to regulate water loss, and many plants also have hairs on their leaves that help to reduce evaporation by trapping a layer of humid air next to the leaf surface.
