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 Melatonin and Serotonin
The key difference between melatonin and serotonin is that melatonin is a hormone that helps us to fall asleep while serotonin is a neurotransmitter that helps us feel awake when we get up the next day. Melatonin is a neurotransmitter-like substance. It is a hormone which increases during the dark. Serotonin is a neurotransmitter that […]
Difference Between Right and Left Atrium
The key difference between right and left atrium is that right atrium receives deoxygenated blood from the body while left atrium receives oxygenated blood from the lung. The human heart has four muscular chambers: two atria and two ventricles. Atria are the two upper chambers of the heart that receive blood. The atrium situated at […]
What is the Difference Between Vasculogenesis and Angiogenesis
The key difference between vasculogenesis and angiogenesis is that vasculogenesis refers to the de novo synthesis of blood vessels during embryonic development, while angiogenesis refers to the synthesis of blood vessels from pre-existing cells during the lifetime. Vasculogenesis and angiogenesis are essential processes in the development and maintenance of life. However, vasculogenesis takes place during […]
Difference Between Autonomic and Paratonic Movements
The key difference between autonomic and paratonic movements is that autonomic movements are the responses to a stimulus generated within the plant due to genes while paratonic movements are the responses of plants to an external stimulus without the involvement of genes. Plants respond to external stimuli; they also respond to the stimuli generated within […]
Difference Between IGF1 and IGF2
The key difference between IGF1 and IGF2 is that IGF1 is a major growth factor in adults, while IGF2 is a major growth factor in the fetus. Insulin-like growth factor 1 (IGF1) and insulin-like growth factor 2 (IGF2) are two peptide hormones that work similar to the insulin hormone. Both hormones can stimulate growth and […]
Difference Between Protandry and Protogyny
The key difference between protandry and protogyny depends on the maturation of the male and female parts. Protandry is the phenomenon in which male parts mature prior to female parts in an organism while protogyny is the phenomenon in which female parts mature prior to male parts. The concepts of protandry and protogyny explain 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 […]
