There are 27 families of flowering plants whose earliest ancestors diverged from what became the two most prominent groups of flowering plants, the eudicots and monocots. [1] [a] They are quite diverse, with woody and non-woody plants, evergreen and deciduous shrubs and trees, and plants that grow in soil, in water and on other plants.
[a] They developed more than 350 million years ago, long before flowering plants, according to the fossil record. The name comes from the Greek for "naked seed"; the egg cells are not protected by ovaries, as in flowering plants. [4] Gymnosperms are divided into 12 families of trees, shrubs and woody vines. [5]
The plants of a layer, especially with regard to their way of life and correspondingly similar root distribution interact closely and compete strongly for space, light, water and nutrients. The stratification of a plant community is the result of long selection and adaptation processes. Through the formation of different layers a given habitat ...
Olericulture is the science of vegetable growing, dealing with the culture of non-woody plants for food. Olericulture is the production of plants for use of the edible parts. Vegetable crops can be classified into nine major categories: Potherbs and greens – spinach and collards; Salad crops – lettuce, celery
Chloroplasts (green discs) and accumulated starch granules in cells of Bryum capillare. Botanically, mosses are non-vascular plants in the land plant division Bryophyta. They are usually small (a few centimeters tall) herbaceous (non-woody) plants that absorb water and nutrients mainly through their leaves and harvest carbon dioxide and sunlight to create food by photosynthesis.
As long as a non-native plant is not invasive, some can also help pollinators by providing nectar and pollen throughout the season, often filling in the gaps for the native plants. Pollinators ...
Another sense of the term herb can refer to a much larger range of plants, [10] with culinary, therapeutic or other uses. [6] For example, some of the most commonly described herbs such as sage, rosemary and lavender would be excluded from the botanical definition of an herb as they do not die down each year, and they possess woody stems. [8]
A xerophyte (from Greek ξηρός xeros 'dry' + φυτόν phuton 'plant') is a species of plant that has adaptations to survive in an environment with little liquid water. Examples of xerophytes include cacti, pineapple and some gymnosperm plants. The morphology and physiology of xerophytes are adapted to conserve water during dry periods.
