A floral diagram is a schematic cross-section through a young flower. [1] It may be also defined as “projection of the flower perpendicular to its axis”. [3] It usually shows the number of floral parts, [Note 2] their sizes, relative positions and fusion. Different organs are represented by distinguishable symbols, which may be uniform for ...
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 ...
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 ABC model of flower development is a scientific model of the process by which flowering plants produce a pattern of gene expression in meristems that leads to the appearance of an organ oriented towards sexual reproduction, a flower. There are three physiological developments that must occur in order for this to take place: firstly, the ...
Plant morphology. Phytomorphology is the study of the physical form and external structure of plants. [1] This is usually considered distinct from plant anatomy, [1] which is the study of the internal structure of plants, especially at the microscopic level. [2] Plant morphology is useful in the visual identification of plants.
Diagram of flower parts. In botany, floral morphology is the study of the diversity of forms and structures presented by the flower, which, by definition, is a branch of limited growth that bears the modified leaves responsible for reproduction and protection of the gametes, called floral pieces. [note 1] Fertile leaves or sporophylls carry ...
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (/ ˌ æ n dʒ i ə ˈ s p ər m iː /), [5] [6] commonly called angiosperms.They include all forbs (flowering plants without a woody stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants.
Petal. Diagram showing the parts of a mature flower. In this example, the perianth is separated into a calyx (sepals) and corolla (petals) Petals are modified leaves that surround the reproductive parts of flowers. They are often brightly coloured or unusually shaped to attract pollinators.
