Difference Between Chloroplast and Chromoplast Chromoplast What is Chromoplasts and its function? The chromoplast is a plastid located in the cytoplasm of a plant cell. It is responsible for producing and storing pigment molecules that are used in photosynthesis, such as chlorophylls and carotenoids. This blog post will go over how these pigments are produced…
Structure and Function of Xylem and Phloem The xylem and phloem are two of the four types of plant tissue, both central to the process of photosynthesis. The other two types are called “parenchyma” or “collenchyma.” Xylem is a type of vascular plant tissue that transports water and minerals from the roots to parts of…
What is Apomixis, and What is its Importance? What is Apomixis? Apomixis (asexual seed formation) occurs when a plant develops the ability to avoid the most basic aspects of sexual reproduction: meiosis and fertilization. The resulting seed germinates a plant that grows as a maternal clone without the need for male fertilization. Apomixis is a…
Difference Between Epicotyl and Hypocotyl Epicotyl An epicotyl is the first part of a seedling, from which emerge the cotyledons and plumule. This organ is responsible for converting the nutrients and water absorbed by the seed into energy, which will be used to support the growth of the seedling. Epicotyl Functions An epicotyl functions primarily…
Difference Between Taproot and Fibrous Root Plant Root Systems Root systems are a vital part of the sustenance of a plant. Plants need roots to absorb water and to help anchor them in the ground. Root systems also provide a place for the roots to live and to store food. Fibrous roots and taproot are…
Adventitious Roots What are Adventitious Roots? Adventitious roots are roots that sprout from a stem or the trunk of a tree. Adventitious roots are often formed when a plant has been injured. The injury is caused by the plant being exposed to freezing temperatures, excessive winds, or insects. Adventitious roots can also form when a…
Transpiration Pull Theory What is Transpiration Pull Theory? Transpiration pull theory states that the movement of water vapor from the soil to plant leaves is by a process which will be known as “transpiration pull”. Transpiration pull theory is also known as the “soil-plant-atmosphere continuum model“. The Transpiration Pull Theory is one of many theories…
Parallel Venation Plants Parallel venation is found in plants with leaves divided into a network of veins that are parallel on both surfaces. This structure is thought to increase the surface area of the leaf which in turn assists in gas exchange. Venation is the branching pattern of the veins of leaves. All plants have…
What is Reticulate Venation? Reticulate venation is a pattern of branching veins that are visible on the surface of leaves. Reticulate venation can be seen when looking at the leaf’s underside, or sometimes even in cross-section. The patterns vary depending on which type they are and what species it belongs to. Reticulate venation often…
Tracheophytes Tracheophytes are vascular plants with lignified and non-lignified tissues that include angiosperms, clubmosses, ferns, horsetails, and gymnosperms. Compared to non-vascular plants, these plants have vascular tissues that allow them to grow to large sizes. Nutrients and water in the form of organic solutes are distributed throughout the plant body by the xylem, and the…
