Shoot system of the plant is an outgrowth originates from the plumule of the seed’s embryo, above the ground. A term shoot is generally interchangeable with the stem, as it constitutes the major part of the shoot system. The morphology and physiology of the shoot system are more complex than the root system of the …
Parenchyma in plants are the types of simple permanent tissue which has some of the ideal properties that distinguish it from the other cells: Cell division: Parenchyma tissue has not the ability to undergo cell division. Vacuole: These comprises a large vacuole. Nature: Structurally and physically, parenchyma is a kind of unspecialized tissue. Modification: Parenchyma …
Difference Between light reaction and dark reaction are mainly due to the following properties: The demand for light: A light reaction demands the source of light energy for the breakdown of water into oxygen, while dark reaction does not need a light source. Site of occurrence: A light reaction resides within the thylakoid membrane, whereas …

Chlorophyll in plants is a pigment molecule that imparts green colour to the leaf and stems by absorbing a red and blue spectrum of light. The term chlorophyll has originated from the Greek terms “Khloros” which means green and “Phyllon” which means leaf. It plays a fundamental role in the process of photosynthesis by allowing …
The difference between root and stem is due to the following properties like: Origination: Roots originate from the radicle by the germination of seed whereas shoots originate from the plumule of developing the embryo. Arrangement of vascular bundles: In roots, the vascular bundles are arranged in the central core while in shoots, arranged in a …
Chloroplast in a plant cell is a membrane-bound cell organelle, contain chlorophyll pigments that are absent in the animal cell. The study of chloroplast was first carried by a scientist named Hugo Von Mohl in the year 1837. After his study, it was found that the chloroplasts were the type of plastids and hence it …
The difference between chlorophyll and chloroplast is due to the following factors: Existence Chlorophyll exists as a primary photosynthetic pigment inside the chloroplast. Chloroplast exists as photosynthetic cell organelles in a plant cell and appears as a membranous structure that resembles mitochondria. Involvement in photosynthesis Chlorophyll mainly absorbs blue and red light energy from the …
The root system in plants is a part which remains subterranean or underground the soil in the vascular plants. It provides strength and rigidity to the growing plant against adverse conditions. Some of the trees like a banyan tree, bonsai tree have their root system over the ground, which refers as “Aerial roots”. Unlike stems, …
Stomata in plants appear as minute pores primarily in the epidermis layer of the leaf surface and also in some of the herbaceous stems. It is originated from the Greek word “Stoma” which means mouth to relate it with the stomatal pore. A stoma is a singular form, whereas more than single stoma termed as …
Transpiration in plants is a process of water loss (in the form of water vapours) into the atmosphere, from the leaf surface and stems. A plant undergoes transpiration primarily to access carbon-dioxide needed for photosynthesis and to cool itself. As the plants are immobile, they manage their water needs by the two fundamental processes like …
