Dicotyledon plantlet Young castor oil plant showing its prominent two embryonic leaves (), which differ from the adult leaves. The dicotyledons, also known as dicots (or, more rarely, dicotyls), [2] are one of the two groups into which all the flowering plants (angiosperms) were formerly divided.
In evolutionary biology, mimicry in plants is where a plant evolves to resemble another organism physically or chemically. Mimicry in plants has been studied far less than mimicry in animals . It may provide protection against herbivory , or may deceptively encourage mutualists, like pollinators , to provide a service without offering a reward ...
[1] [2] Examples of distylous plants are the primrose and many other Primula species, [1] [2] buckwheat, flax and other Linum species, some Lythrum species, [3] and many species of Cryptantha. [4] Heterostylous plants having three flower morphs are termed "tristylous". Each morph has two types of stamens.
Plants with more than one significant human use may be listed in multiple categories. Plants are considered domesticated when their life cycle , behavior , or appearance has been significantly altered as a result of being under artificial selection by humans for multiple generations (see the main article on domestication for more information).
Botany is a natural science concerned with the study of plants.The main branches of botany (also referred to as "plant science") are commonly divided into three groups: core topics, concerned with the study of the fundamental natural phenomena and processes of plant life, the classification and description of plant diversity; applied topics which study the ways in which plants may be used for ...
Distyly is a breeding system in plants that is characterized by two separate flower morphs, where individual plants produce flowers that have either long styles and short stamens (L-morph flowers) or short styles and long stamens (S-morph flowers). [1]
About 10–15% of flowering plants are predominantly self-fertilizing. [9] Self-pollination is an example of autogamy that occurs in flowering plants. Self-pollination occurs when the sperm in the pollen from the stamen of a plant goes to the carpels of that same plant and fertilizes the egg cell
This is a list of plant hybrids created intentionally or by chance and exploited commercially in agriculture or horticulture. The hybridization event mechanism is documented where known, along with the authorities who described it.
