The key difference between microspore and pollen grain is that microspore is the small spore that develops into the male gametophyte in plants while pollen grain is the small grain that contains the male gametophyte. Plant reproduction takes place both sexually and asexually, showing the alternation of generation. There are two generations known as sporophytic […]
Difference Between Epicotyl and Plumule
The key difference between epicotyl and plumuleĀ is that epicotyl is the part of the embryonic axis which lies above the point of attachment of cotyledons while plumule is the tip of the epicotyl which gives rise to the shoot of the new plant. The seed is the ripened ovule which contains the embryo. Here, the […]
Difference Between Endosperm and Perisperm
The key difference between endosperm and perisperm is that endosperm is a nutritive tissue of the seed that is triploid in nature, while perisperm is another nutritive tissue of the seed that is diploid in nature. Seed plants have two major categories as angiosperms and gymnosperms. Angiosperms bear closed seeds while gymnosperms bear naked seeds. […]
Difference Between Guard Cells and Subsidiary Cells
The key difference between guard cells and subsidiary cells in plants is that guard cells are the specialized parenchyma cells that enclose stomata present in the epidermis of leaves, stems, etc. while subsidiary cells are the surrounding supportive cells of guard cells. Stomata are the pores located in plant epidermis that facilitate the gaseous exchange. […]
Difference Between Primary Xylem and Secondary Xylem
The key difference between primary xylem and secondary xylem is that the procambium forms the primary xylem during the primary growth, while the vascular cambium forms the secondary xylem during the secondary growth. Xylem and phloem are the main types of complex tissues in plants. The xylem tissue in higher vascular plants transport water and […]
Difference Between Shoot and Stem
The key difference between shoot and stem is that shoot is an above-ground part of a plant and consists of leaves, buds, flowering stems, flowering buds and the main stem, while stem is the main structural axis of the plant that consists of nodes and internodes. A plant has different parts. Shoot system and root […]
Difference Between Root Hair and Stem Hair
The key difference between root hair and stem hair is that the root hair is a unicellular structure developed as an outgrowth of the epidermis, while the stem hair is a multicellular structure that is not an outgrowth of the epidermis. Root and stem are two main parts of a plant. Stem exists above the […]
Difference Between Insect and Wind Pollination
The key difference between insect and wind pollination is that the plants that use insect pollination produce colourful, attractive and scented flowers, while the plants that use wind pollination produce small, dull and less attractive flowers. Pollination is the process of transferring pollen from anthers to the stigma of a flower. There are two types […]
Difference Between Hilum and Micropyle
The key difference between hilum and micropyle is that helium is an elliptical scar on the seed, which marks the point of attachment to its seed vessel, while micropyle is a small pore from which the pollen tube enters the ovary prior to fertilization. A seed is a fertilized ovule of a seed plant. There […]
Difference Between Staminate and Pistillate
The key difference between staminate and pistillate is that staminate flower is a flower that contains only stamens (male reproductive organs) while pistillate flower is a flower that contains only pistils or carpels (female reproductive organs). The flower is the reproductive structure of flowering plants or angiosperms. A flower has different parts including petals, sepals, […]
