The cactus is a plant that flowers, and the blooms generate fruit that bears seeds; it is the seeds that end up leading to new cactus plants. Bats provide the pollination for some species of cactus, and the flowers bloom in the spring each year. It is also possible to grow a cactus from broken fragments of an existing cactus, but the new plant is genetically identical.
The fact that cactuses need to attract bats (or bees or birds, in some cases) to provide pollination led them to develop several floral traits that attract pollinating species. Once pollination has taken place, the fruits that cactuses produce show considerable variety. Some are very dry, while others are quite fleshy, and they all have a lot of seeds. Birds disperse the seeds found in fruits that taste sweet and show a lot of color; the birds consume the fruit, and the seeds pass through the birds' digestive systems, ending up on the ground in the bird droppings. Some cactus fruit falls on the ground, where members of other species consume the fruit. Ants even disperse seeds for some species. Fruits that are drier and have spines end up sticking to mammal fur or travel with the wind in order to disperse the seeds inside.Learn More
Moss reproduces both sexually and asexually. For sexual reproduction, plants produce a male and female structure, often on different plants, and the sperm swims toward the eggs to accomplish fertilization. In the case of asexual reproduction, any time part of the stem or even just a leaf breaks off, the bits regenerate to create a new moss plant.Full Answer >
The nopal cactus, or prickly pear cactus, comprises a variety of species of Opuntia that are native to and grow extensively throughout Mexico, as well as the southwestern desert regions of the United States. The cactus is a common part of Mexican cuisine and is also taken medicinally.Full Answer >
Sedum seeds are used to grow a perennial that has thick leaves and clustering blooms. Sedums are available in hundreds of species ranging from small ground-cover plants to taller ornamental bushes. Available sedum colors include pink, red, white and yellow, and they bloom from the spring through the fall.Full Answer >
Bigger seeds do not necessarily grow faster than smaller seeds. In many cases, the opposite is true. The germination time of a seed depends on what plant it's from, how long it's been dormant and the conditions under which it's planted.Full Answer >
