The stages of germination of a pea plant: A. seed coat, B. radicle, C. primary root, D. secondary root, E. cotyledon, F. plumule, G. leaf, H. tap root. The part of the plant that first emerges from the seed is the embryonic root, termed the radicle or primary root. It allows the seedling to become anchored in the ground and start absorbing water.
In addition to growth by cell division, a plant may grow through cell elongation. This occurs when individual cells or groups of cells grow longer. Not all plant cells grow to the same length. When cells on one side of a stem grow longer and faster than cells on the other side, the stem bends to the side of the slower growing cells as a result.
Anatomy of a flower. A flower's anatomy, as defined by the presence of a series of organs (sepals, petals, stamens and carpels) positioned according to a given pattern, facilitate sexual reproduction in flowering plants. The flower arises from the activity of three classes of genes, which regulate floral development: [8]
When growing bulbs indoors, be sure to plant them very close together, says Montgomery. Generally, about six tulip bulbs, three hyacinths, or six daffodils will fit into a 6-inch pot. Use a clean ...
They do not need to attract pollinators and therefore tend not to grow large, showy, or colorful flowers, and do not have nectaries, nor a noticeable scent. Because of this, plants typically have many thousands of tiny flowers which have comparatively large, feathery stigmas; to increase the chance of pollen being received.
Begonia. Available in a wide variety of colors, begonia plants are great for beginner gardeners to grow. These tiny flowers prefer filtered light or partial shade as all-day, direct sunlight can ...
Plant enthusiasts and growers learned significant details about growing certain plants over the years. Chrysanthemums have been cultivated in China for over 3000 years, [13] so growers knew about the plant and how to grow it. Floriculture scientists have simply continued this trend to control the plant's environment to control flowering for the ...
The agricultural cycle is the annual cycle of activities related to the growth and harvest of a crop (plant). These activities include loosening the soil, seeding, special watering, moving plants when they grow bigger, and harvesting, among others. Without these activities, a crop cannot be grown.
