Apical Meristem vs. Lateral Meristem
Apical meristem is involving in the prime growth of the plant that rises the length at the apex whereas lateral meristem is participating in the subsequent development of the plant that grows in diameter. Apical meristem is the meristematic tissue at the top of stem and roots, which is responsible for the primary growth of the plant whereas lateral meristem is the meristematic tissue at the margins of stems and roots, which is responsible for the secondary growth of the plant. The apical meristem rises the length of the plant at the apex of stem and roots, but the lateral meristem increases the diameter of stem and roots. The apical meristem contains procambium, protoderm, and ground meristem, on the other hand, the lateral meristem comprises cork cambium and vascular cambium. The apical meristem gives an increase in the xylem, epidermis, phloem, and ground tissue conversely the lateral meristem gives rise to inner bark, wood, and outer bark. The apical meristem permits the plant to develop into unique structures like leaves and flowers, but the lateral meristem permits the plant to grow into tall by making it stronger. The apical meristem happens in all species of plants on the flip side the lateral meristem is absent in horsetails and mosses.
What is Apical Meristem?
The apical meristem is the growth area in plants present within the root tips and the tops of the new shoots and leaves. Apical meristem is a cluster of the dense pack and undifferentiating cells. It involves in the prime growth of the plant by increasing the length of the plant. Apical is an explanation of progress occurring at the tips of the plant, both top, and bottom. Apical meristem is responsible for making cells and growth to drive the plant into the light and air, where it can photosynthesize and exchange gases. Cells in the apical meristem are not generalizing and keenly divide to produce new cells throughout the plant life, but cells in the center of the plant steadily lose their power of division and become a stable tissue these cells become vacuolated and expanding by absorbing water. The conditions of the soil around the roots are detecting, and signals are creating within the apical meristem which directs the plant towards the water and desired nutrients. The primary central cells in the apical meristem are first differentiating into procambium protoderm, and ground meristem. The plant’s vascular tissue, phloem, and xylem are separating from procambium. The protoderm is dividing into the epidermis. Ground meristem is differentiating into the ground tissue that stores food in the form of starch and provides support to the plant. Its principal function is to activate the growth of new cells in new seedlings at the tips of roots and shoots and developing buds.
What is Lateral Meristem?
The lateral meristem lies alongside the stem and roots involving in the secondary growth. Secondary growth occurs only in dicots. The lateral meristem is present in all woody plants and is responsible for the thickening of the vascular cambium and the cork cambium. The vascular cambium produces both secondary xylem and phloem. The secondary xylem is originating inside the stem tissue and is known as wood, and the secondary phloem is creating in the stem boundary which provides the inner bark. The differential growth of the vascular cambium provides annual rings in the stem. They provide secondary tissues from a circle of vascular cambium in stems and roots. Cork cambium lies closer to the surface, produces the outer bark. It serves as the secondary lateral meristem.
