Some plants can store water in their root structures, trunk structures, stems, and leaves. Water storage in swollen parts of the plant is known as succulence. A swollen trunk or root at the ground level of a plant is called a caudex and plants with swollen bases are called caudiciforms.
Factors of the physical or abiotic environment include temperature, water, light, carbon dioxide, and nutrients in the soil. [62] Biotic factors that affect plant growth include crowding, grazing, beneficial symbiotic bacteria and fungi, and attacks by insects or plant diseases. [63] Frost and dehydration can damage or kill plants.
This allows the mollusks to survive solely by photosynthesis for several months at a time. [18] [19] Some of the genes from the plant cell nucleus have even been transferred to the slugs, so that the chloroplasts can be supplied with proteins that they need to survive. [20] An even closer form of symbiosis may explain the origin of chloroplasts.
Etiolation / iː t i ə ˈ l eɪ ʃ ən / is a process in flowering plants grown in partial or complete absence of light. [1] It is characterized by long, weak stems; smaller leaves due to longer internodes; and a pale yellow color . The development of seedlings in the dark is known as "skotomorphogenesis" and leads to etiolated seedlings.
These include the amount of light available, the amount of leaf area a plant has to capture light (shading by other plants is a major limitation of photosynthesis), the rate at which carbon dioxide can be supplied to the chloroplasts to support photosynthesis, the availability of water, and the availability of suitable temperatures for carrying ...
Tiny hair-like structures called trichomes on the surface of leaves also can inhibit water loss by creating a high humidity environment at the surface of leaves. These are some examples of the adaptations of plants for the conservation of water that may be found on many xerophytes. Light supply
A germination rate experiment. Plant physiology is a subdiscipline of botany concerned with the functioning, or physiology, of plants. [1]Plant physiologists study fundamental processes of plants, such as photosynthesis, respiration, plant nutrition, plant hormone functions, tropisms, nastic movements, photoperiodism, photomorphogenesis, circadian rhythms, environmental stress physiology, seed ...
Plants can only use a fraction (approximately 1%) of this energy for photosynthesis. [11] The process of photosynthesis splits a water molecule (H 2 O), releasing oxygen (O 2 ) into the atmosphere, and reducing carbon dioxide (CO 2 ) to release the hydrogen atoms that fuel the metabolic process of primary production .
