Pine trees belong to the Pinaceae family of evergreen coniferous trees that have a life cycle lasting between 50-450 years.Pine trees come in a variety of shapes and sizes, and there are over 125 different kinds. The northern hemisphere is where pine trees thrive, while in the southern hemisphere, a variety of pine tree species have been artificially introduced to temperate and subtropical locations.Europe, Africa, Asia, the United States, and Canada are all places where pine trees can be found. Temperate and subtropical regions are ideal for pine tree growth. Pine trees grow 10–260 ft (3–79 m). A pine tree thrives well in sandy or well-drained soil. To live, fully grown pine trees need full sun and little water. Pines are long living trees that can survive for 100–1,000 years, and some pine tree species can live for even longer.Most pine trees generate huge whorls of lower branches that run up a straight trunk from the forest floor. Many pine trees are unimodal, producing only one whorl of branches per year from buds at the new shoot’s tip, but others are multi-nodal, producing two or more whorls per year.Non-flowering plants reproduce with the help of spores or seeds, unlike flowering plants.What are the major groups of pine trees? What is the role of pine nuts? How are they different from deciduous trees? How does pollination work? Read on to know why pine trees produce seeds and what is the process of pollination they follow.Comparing Flowering Plants And ConifersBelow are some important aspects related to the comparison between conifers and flowering plants.Flowering plants: When it comes to the most common types of plants, flowering plants emerge at the top of the list. Most trees and shrubs present on the Earth feature in this category. These plants possess a particular type of vascular structure. Another interesting aspect of flowering plants is the reproductive structure as there are both male and female reproductive organs present in the flower. Moreover, the flower can be unisexual or bisexual. As the ovary houses all the ovules, the ovary covers the viable seeds that later develop into fruits.Conifers: The other category of plants that have a longer lifespan is conifers or Pinophyta. They also last a long time and are evergreen. Woody vegetation makes up the majority of coniferous trees. To reduce water loss, its leaves have a needle-like shape. As a result, conifers are more suited to living in snowy climates. Their xylem, on the other hand, is made up entirely of tracheids, while for the purpose of conduction, the phloem features sieve cells.Conifers are unable to generate flowers in the same way that flowering plants do. Conifers’ unisexual cones serve as reproductive structures. Microsporophylls in male cones create microspores, while megasporophylls produce megaspores in female cones.The major distinction between flowering plants and conifers is that flowering plants are angiosperms, which generate flowers as their reproductive structure, whereas conifers are gymnosperms with cones as their reproductive structure. Furthermore, the ovary of the flowering parent plant encloses seeds, whereas, conifers generate naked seeds.Pine Tree HealthThere are important health benefits of pine trees that have been popular since prehistoric times.Pine and its many extracts are utilized in traditional medicine in a variety of ways. The benefits of pine needle tea are less well-known than those of its other elements, such as bark and pollen. Traditional medicine, on the other hand, makes great use of these.Pine tree compounds are thought to be high in antioxidants, which may help to protect you from disease. Antioxidant and anti-inflammatory substances were discovered in pine bark extract.Pine tree needle tea is thought to have vitamins C and A which are good for eyesight. French maritime pine tree’s bark extract was found to be quite helpful in the treatment of problems such as diabetic retinopathy.Coughing and sore throats may be relieved with pine tree needle tea which is sometimes used for treating respiratory problems, such as inflammation of the respiratory system.Flowers Vs ConesAngiosperms are seed plants that blossom and their seeds grow inside the tissue that is part of the plant’s ovaries, more generally known as the fruit of the species.Conifers are gymnosperms, which means their seeds are not wrapped in fruit and grow naked, commonly on the scales of a cone.Male cones are commonly positioned on branches above females in cone-bearing gymnosperms, which are meant to be pollinated by the wind. Insects, birds, and small mammals are widely used to pollinate fruit-bearing angiosperms.Male Vs Female PinesMentioned below are some of the most important differences between male and female species of pine cones.Male pine cones: Male pine cones are smaller and live for a shorter period of time than female pine cones. Scales, or microsporophylls, surround a central stem in these brown, tube-like clusters on the branches of a pine. Each pollen bag, or microsporangium, is held by a scale, and each pollen sack contains pollen grains, each of which is referred to as a microgametophyte, or microspore.Female pine cones: A female cone is the most common type of pine cone. Unlike male cones, they live for several years and expand their scales more widely. Female cones are frequently found lower on the tree, allowing them to benefit from pollen falling downward. Female pine cones include scales, just like male cones, but the scales on female pine cones are significantly larger and are known as megasporophylls.Pine PollinationMicrospores in the male microsporangium of a pine tree undergo mitosis and transform into male gametophytes, often known as pollen. When the male gametophyte is expelled by the male cone, it possesses two air bladders that will let it float on the air. Male cones are higher in the pine tree than female cones in some conifers, allowing pollen to take advantage of the extra height when released, allowing it to float farther when carried away by the wind or breeze.Male and female pine cones contain a megasporangium structure. A female megaspore in the megasporangium undergoes mitosis and transforms into a female megagametophyte. After that, each megagametophyte develops an archegonium, which contains an egg.Some pine cones remain tightly closed until they reach an extremely high temperature, as would be present in a forest fire.
