Chloroplasts in leaf cells of the moss Mnium stellare. Plant anatomy or phytotomy is the general term for the study of the internal structure of plants.Originally, it included plant morphology, the description of the physical form and external structure of plants, but since the mid-20th century, plant anatomy has been considered a separate field referring only to internal plant structure.
The pineapple is an example of a CAM plant.. Crassulacean acid metabolism, also known as CAM photosynthesis, is a carbon fixation pathway that evolved in some plants as an adaptation to arid conditions [1] that allows a plant to photosynthesize during the day, but only exchange gases at night.
Mimicry is an adaptation by a species, called the mimic, making it resemble something else, called the model, with the effect of deceiving another species, the dupe. The three are not always all distinct, as mimicry can for example be within a species. [3] The adaptation is to the evolutionary advantage of the mimic.
Heliophytes or sunstroke plants are adapted to a habitat with a very intensive insolation by their structure and metabolism. Examples are mullein, ling, thyme and soft velcro, white clover, and most roses. They are common in open terrain, rocks, meadows, as well as at the mountain pastures and grasslands and other long sunny exposures. [1] [2]
A xerophyte (from Greek ξηρός xeros 'dry' + φυτόν phuton 'plant') is a species of plant that has adaptations to survive in an environment with little liquid water. Examples of xerophytes include cacti, pineapple and some gymnosperm plants. The morphology and physiology of xerophytes are adapted to conserve water during dry periods.
Three of the most common and important structural adaptations of ant plants are extrafloral nectaries, domatia, and (least commonly) Beltian bodies. Plant domatia are formed nesting sites provided by the plant in the form of hollow stems, petioles, thorns, or curled leaves. [17]
However, it is not clear what "relatively small" should mean, for example polyploidy in plants is a reasonably common large genetic change. [22] The origin of eukaryotic endosymbiosis is a more dramatic example. [23] All adaptations help organisms survive in their ecological niches. The adaptive traits may be structural, behavioural or ...
The plants behind drought tolerance are complex and involve many pathways which allows plants to respond to specific sets of conditions at any given time. Some of these interactions include stomatal conductance , carotenoid degradation and anthocyanin accumulation, the intervention of osmoprotectants (such as sucrose , glycine , and proline ...
