Phanerogams

Spermatophytes (also known as phanerogam or phaenogam ) are any plant that produces seeds, hence the alternative name seed plant. They are descended from the Greek words spérmatos (seed) and phytón (plant), which means seed-bearing plants’. Spermatophytes are a subset of embryophytes, which are also known as land plants. As opposed to cryptogamae (from the […]

Pericarp

An ovary of a flowering plant that has become fleshy or dry and has ripened, enclosing the seed or seeds As a result, fruits such as apricots, bananas, and grapes, as well as bean pods, corn grains, tomatoes, cucumbers, and (in their shells) acorns and almonds, are all considered to be fruits under the legal

Pepo

Cucurbita pepo is a cultivated plant of the genus Cucurbita that is grown for its fruit. The plant produces a variety of winter squash and pumpkin varieties, but the most widely cultivated varieties are those of the Cucurbita pepo subsp. pepo, also known as summer squash. Since the beginning of time, humans have been domesticating

Pentalocular

Angiosperms (flowering plants) have locules, which are chambers that are usually found within the ovary (gynoecium or carpel) that contain the flowers and fruits. Fruits can be classified as unilocular , bilocular, trilocular , or penta-locular depending on the number of locules present in the ovary. An individual gynoecium may have an equal or less

Pentacarpellary

A pentacarpellary, syncarpous, with a superior ovary G (5) which indicates that the gynoecium (represented by the letter G) is composed of five carpels (pentacarpellary-represented by the number 5), the carpels are united (syncarpous-represented by the brackets), and the gynoecium is hypogynous. When the carpels are separated from one another, this is referred to as

Parts of the root

Vegetative parts like root, stem, leaves and other parts like flowers and their tiny buds are vital parts of plants, although these structures are very varied, tailored to different plant species’ demands and environments. These organs are equally crucial to the plants as much as plants are necessary for the survival of human beings. Let

PARTS OF PLANTS

The morphology and other properties of plants are used to classify them. Roots, stems, leaves, fruit, and flowers are used to classify plants. As a result, it’s critical to properly understand the structure and functions of each part. Each part of the plant has a specific purpose that is useful to the plant’s growth. Roots

Parts of Flowers

In flowering plants, the organ of reproduction is the flower. A typical flower has four different parts sepals, petals, stamens and carpel. Plants carry out sexual reproduction with the help of flowers. The fruit which develops after fertilisation bear seeds that germinate and start the next generation. The plants of the next generation always show

Parts of a seed

A flowering plant’s seed is an essential component of the plant’s life cycle. They result in the growth of a new plant. They can be found in a variety of shapes, colours, and sizes. They can be round, wrinkled, winged, or hairy depending on the species. They are in a dormant state until such time

Parts of a fruit

Fruit is a seed-bearing structure found in flowering plants, which are also known as angiosperms, and is responsible for the production of seeds. Flowering in a plant causes the formation of an ovary in the seed, which is then used to produce an egg. It is through the fruit that angiosperms disseminate their seeds. The
