The key difference between tropic and nastic movement is that tropic movement is a directional response while nastic movement is a non-directional response. Plants respond to different types of stimuli, such as light, water, gravity, touch, and chemicals. Some plant parts also show movements as a response to a stimulus. Some responses depend on the […]
Difference Between Source and Sink in Plants
The key difference between source and sink in plants is that source in plants is the site of food production using biological processes while sink in plants is the site of food storage for later use. Source and sink in plants are two important terminologies used in phloem translocation. Phloem translocation is the process of […]
Difference Between Holly and Mistletoe
The key difference between Holly and Mistletoe is that Holly is a genus of flowering plants while Mistletoe is a common name used to refer to most semi-parasitic plants that belong to the order Santalales. Both holly and mistletoe are two types of plants. Holly plants could be evergreen trees, shrubs or climbers. In contrast, […]
Difference Between Pteridophytes and Phanerogams
The key difference between pteridophytes and phanerogams is that pteridophytes are seedless and flowerless vascular plants while phanerogams are seed and flower-bearing vascular plants. Kingdom Plantae has two sub-kingdoms as cryptogamae and Phanerogamae. Cryptogamae includes plants that reproduce through spores. Thus, those plants are seedless and flowerless plants. Furthermore, the sub-kingdom has three main groups […]
Difference Between Insectivorous and Symbiotic Plants
The key difference between insectivorous and symbiotic plants is that the insectivorous plants feed on insects through trapping and digesting them while symbiotic plants maintain a close relationship with another plant species which is mutually beneficial for both or either one of them. Plants possess different modes of nutrition. Furthermore, the type of nutrition varies […]
Difference Between Protostele and Siphonostele
The key difference between protostele and siphonostele is that protostele is the most primitive type of stele that consists of a solid core of xylem without a central pith while siphonostele is a modification of protostele that consists of a cylindrical vascular system surrounding a central pith. The stele is the central portion of a […]
Difference Between Sieve Tubes and Companion Cells
The key difference between sieve tubes and companion cells is that the sieve tubes are the phloem sieve elements that conduct food in angiosperms whereas, companion cells are the associated cells of sieve tubes. Moreover, sieve tubes have pores in the transverse walls while companion cells do not have pores. Phloem is one of the […]
Difference Between Collenchyma and Chlorenchyma
The key difference between collenchyma and chlorenchyma is that collenchyma is a type of ground tissue that provides mechanical and structural support to a plant while chlorenchyma is a modified parenchyma tissue that contains chloroplasts and is photosynthetic. There are three types of ground tissue as parenchyma, collenchyma, and sclerenchyma. They are neither dermal nor […]
Difference Between Protoxylem and Metaxylem
The key difference between protoxylem and metaxylem is that protoxylem is the first formed primary xylem which has smaller cells, especially narrow vessels and tracheids while metaxylem is the later formed primary xylem which has larger cells, especially wider vessels, and tracheids. Xylem is one of the two types of vascular tissues in plants. Xylem […]
Difference Between C4 and CAM Plants
The key difference between C4 and CAM plants is that in C4 plants, carbon fixation takes place in both mesophyll and bundle sheath cells while in CAM plants, carbon fixation takes place only in mesophyll cells. Most of the plants follow the Calvin cycle, which is the C3 photosynthesis pathway. These plants grow in regions […]
