Theophrastus's Enquiry into Plants or Historia Plantarum (Ancient Greek: Περὶ φυτῶν ἱστορία, Peri phyton historia) was, along with his mentor Aristotle's History of Animals, Pliny the Elder's Natural History and Dioscorides's De materia medica, one of the most important books of natural history written in ancient times, and like them it was influential in the Renaissance.
The Sapindaceae are a family of flowering plants in the order Sapindales known as the soapberry family. It contains 138 genera [2] and 1,858 accepted species. Examples include horse chestnut, maples, ackee and lychee. The Sapindaceae occur in temperate to tropical regions, many in laurel forest habitat, throughout the world.
The findings include: [6] All 50 states have social studies standards which include civics and government. 39 states require at least one course in government/civics. [note 1] 21 states require a state-mandated social studies test which is a decrease from 2001 (34 states). 8 states require students to take a state-mandated government/civics test.
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 ...
Heliotropism, a form of tropism, is the diurnal or seasonal motion of plant parts (flowers or leaves) in response to the direction of the Sun. The habit of some plants to move in the direction of the Sun, a form of tropism, was already known by the Ancient Greeks. They named one of those plants after that property Heliotropium, meaning "sun turn".
A sundew with a leaf bent around a fly trapped by mucilage. Mucilage is a thick gluey substance produced by nearly all plants and some microorganisms.These microorganisms include protists which use it for their locomotion, with the direction of their movement always opposite to that of the secretion of mucilage.

The grand taxonomic synthesis An Integrated System of Classification of Flowering Plants (1981) of American Arthur Cronquist (1919–1992) was superseded when, in 1998, the Angiosperm Phylogeny Group published a phylogeny of flowering plants based on the analysis of DNA sequences using the techniques of the new molecular systematics which was ...
Non-vascular plants are plants without a vascular system consisting of xylem and phloem. Instead, they may possess simpler tissues that have specialized functions for the internal transport of water.
