  2. Palisade cell - Wikipedia

    en.wikipedia.org/wiki/Palisade_cell

    Palisade cells contain a high concentration of chloroplasts, particularly in the upper portion of the cell, making them the primary site of photosynthesis in the leaves of plants that contain them. Their vacuole also aids in this function: it is large and central, pushing the chloroplasts to the edge of the cell, maximising the absorption of ...

  3. Knockout moss - Wikipedia

    en.wikipedia.org/wiki/Knockout_moss

    A knockout moss is a kind of genetically modified moss. One or more of the moss's specific genes are deleted or inactivated ("knocked out"), for example by gene targeting or other methods. After the deletion of a gene, the knockout moss has lost the trait encoded by this gene. Thus, the function of this gene can be inferred.

  4. Light-harvesting complexes of green plants - Wikipedia

    en.wikipedia.org/wiki/Light-harvesting_complexes...

    The light-harvesting complex (or antenna complex; LH or LHC) is an array of protein and chlorophyll molecules embedded in the thylakoid membrane of plants and cyanobacteria, which transfer light energy to one chlorophyll a molecule at the reaction center of a photosystem. The antenna pigments are predominantly chlorophyll b, xanthophylls, and ...

  5. Photosystem I - Wikipedia

    en.wikipedia.org/wiki/Photosystem_I

    Photosystem I (PSI, or plastocyanin–ferredoxin oxidoreductase) is one of two photosystems in the photosynthetic light reactions of algae, plants, and cyanobacteria. Photosystem I [1] is an integral membrane protein complex that uses light energy to catalyze the transfer of electrons across the thylakoid membrane from plastocyanin to ferredoxin.

  6. Plant physiology - Wikipedia

    en.wikipedia.org/wiki/Plant_physiology

    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 ...

  7. Plant cell - Wikipedia

    en.wikipedia.org/wiki/Plant_cell

    Structure of a plant cell. Plant cells are the cells present in green plants, photosynthetic eukaryotes of the kingdom Plantae.Their distinctive features include primary cell walls containing cellulose, hemicelluloses and pectin, the presence of plastids with the capability to perform photosynthesis and store starch, a large vacuole that regulates turgor pressure, the absence of flagella or ...

    Even though you tend to put more focus on the concentric portion of the lift, you’re typically stronger during the eccentric portion, says Mike Nelson, Ph.D., C.S.C.S., an associate professor at ...

  9. Epigenetics of plant growth and development - Wikipedia

    en.wikipedia.org/wiki/Epigenetics_of_Plant...

    The epigenetics of plant growth and development refers to the heritable changes in gene expression that occur without alterations to the DNA sequence, influencing processes in plants such as seed germination, flowering, and stress responses through mechanisms like DNA methylation, histone modification, and chromatin remodeling.
