Pathogens are disease-causing viruses, bacteria, fungi or protists which attack plants as well as animals. Plants have physical and chemical defences against pathogens.

Plants are multicellular organisms in the kingdom Plantae that use photosynthesis to make their own food. There are over 300,000 species of plants; common examples of plants include grasses, trees, and shrubs. Plants have an important role in the world’s ecosystems. They produce most of the world’s oxygen, and are important in the food chain, as ma...
Plants are autotrophs; they produce their own food. They do so via photosynthesis, which is the process of making nutrients such as sugars from light energy and carbon dioxide. Photosynthesis occurs in cell organelles called chloroplasts, which contain chlorophyll and carotenoids, molecules that absorb light energy and change it into a usable form....
Charophytes
Charophytes are complex green algae such as stoneworts. They have cells with chloroplasts, cell walls containing cellulose, and store starch, as plants do. They reproduce sexually and some have sperm with flagella (tails that allow them to move), just like some plants do. Some fossil stoneworts are very similar to modern day ones.
Bryophytes
Bryophytes are nonvascular land plants. They do not have vascular tissue, which is tissue that transports water and nutrients. They are found both on land and in water. Common examples of bryophytes are mosses, liverworts, and hornworts. Bryophytes are generally very similar to algae in their lack of a vascular system. They do have parts similar to roots, stems, and leaves, but these are not the true roots, stems, and leaves found in vascular plants. Liverworts were probably the first land pl...
Seedless Vascular Plants
Seedless vascular plants produce embryos that are not protected by seeds. Instead, they reproduce via spores. Members of this group include ferns, horsetails, quillworts, clubmosses, and spikemosses. These plants used to be called pteridophytes, but this turned out to be an inaccurate group because ferns and horsetails are more closely related to seed plants than to quillworts, clubmosses, and spikemosses. Seedless vascular plants flourished during the Devonian period and in Carboniferous for...

Plants can respond to their environment in various ways. The environmental stimuli to which plants respond can be abiotic or biotic. Examples of plant responses include: responses to abiotic stress. responses to herbivory, e.g. chemical defences. response to touch. tropisms.
Mar 27, 2014 · In this review, we discuss the basics of systems biology including the various ‘omics’ approaches and their integration, the modeling aspects and the tools needed for the plant systems research. A particular emphasis is given to the recent analytical advances, updated published examples of plant systems biology studies and the future trends.

Jul 10, 2021 · At the plant and at the canopy level and over longer time scales (days to weeks), growth often refers to biomass accumulation, resulting from the balance between carbohydrate assimilation (photosynthesis) and losses through respiration, exudation, shedding, or herbivory.

May 18, 2024 · Plants\(_2\) are all organisms from Vegetabilia kingdom. Normally, plants\(_2\) are green organisms with a stem and leaves. We can define them also as multi-tissued, terrestrial, and primarily photosynthetic eukaryotes. This definition is taxonomical (based on evolution).
