The key difference between sieve cells and sieve tubes is that the sieve cells are less specialized sieve elements that lack sieve plates and present in seedless vascular plants and gymnosperms while the sieve tubes are highly specialized sieve elements that have sieve plates and present in angiosperms. Vascular plants possess vascular bundles comprised mainly […]
Difference Between Lycopene and Beta Carotene
The key difference between lycopene and beta carotene is that the lycopene is a carotenoid that has no pro-vitamin A activity while the beta carotene is a carotenoid that is the main precursor for vitamin A. Carotenoids are a group of pigments that provide characteristic colours to fruits and vegetables, and therefore, visible in yellow, […]
Difference Between Chlorophyll and Carotenoids
The key difference between chlorophyll and carotenoids is that the chlorophyll is a family of green colour pigments primarily used for photosynthesis in photosynthetic organisms while the carotenoids are a group of yellow to red colour pigments including carotenes and xanthophylls that are accessory pigments. The pigment is a colourful chemical compound that reflects a […]
Difference Between Light Reaction and Calvin Cycle
The key difference between light reaction and Calvin cycle is the dependence of light in each type of reaction in photosynthesis. Light reaction in photosynthesis is light-dependent whereas the Calvin cycle (or dark reaction in photosynthesis) is light-independent. Photosynthesis is an autotrophic mode of nutrition occurring in plants and other photosynthetic organisms such as algae […]
Difference Between Stomata and Guard Cells
The key difference between stomata and guard cells is that the stomata are pores that locate on the epidermis of leaves, stems, etc., while the guard cells are the cells that surround and regulate the opening and closing of stomata. Respiration and photosynthesis are two vital processes in plants. In both processes, gas exchange is […]
Difference Between Cycads and Palms
The key difference between cycads and palms is that the cycads are gymnosperms that are non-flowering plants while the palms are angiosperms or the flowering palms. Cycads and palms look similar due to their nicely arranged fan-like leaves. However, when analyzing keenly, we can identify a distinct difference between cycads and palms. Cycads are more […]
Difference Between Cycas and Pinus
The key difference between cycas and pinus is that the Cycas is a genus that belongs to the gymnosperm group cycads while Pinus is a genus that belongs to the gymnosperm group conifers. Plants are multicellular, photosynthetic eukaryotes. Kingdom Plantae has two major higher plant groups called Gymnosperms and Angiosperms. Angiosperms are flowering plants, which […]
Difference Between Apical Intercalary and Lateral Meristem
The key difference between apical intercalary and lateral meristem is that the apical meristem situates at the tips of the roots and the shoots while the intercalary meristem situates at the internodes and lateral meristem locates at the lateral side of the stem and the roots. Meristematic tissue in a plant includes the young cells […]
Difference Between Coleoptile and Coleorhiza
The key difference between coleoptile and coleorhiza is that the coleoptile is a protective sheath of the young shoot tip of monocot plants while the coleorhizae is a protective sheath of the radicle and the root of monocot plants. Coleoptile and coleorhizae are two structures of monocot plants. In plant anatomy, the coleoptile and the […]
Difference Between Land Plants and Water Plants
The key difference between land plants and water plants is that the lands plants have a more extensive root system while many of the water plants do not have a root system. Plants are autotrophic living organisms that have the ability to photosynthesize. Photosynthesis takes place in both land plants and water plants, but the […]
