Multicarpellary

The gynaeceum of a flower that has more than one carpel is known as multicarpellary. On the other hand, the gynaeceum of a flower that has a solitary carpel is known as a monocarpellary. The entirety of the word is multi-carpellary syncarpous, which means that the ovary has many carpels fused as one solitary carpel.  […]

General Charateristics of Bryophytes

Bryophytes are a group of small, simple, green land-dwelling plants, of which a few are aquatic. Bryology is called the scientific study of bryophytes. People who have a strong interest in examining, reporting, categorising, or studying bryophytes are called Bryologists.  Bryophytes are also called first land plants. And they have characteristics common to algae and

Morphology of Flowering Plants

Introduction Morphology is the discipline of science that studies the structure, features and form of organisms. The number and form of petals, the number of stamens, the size of the petals, and the number and position of styles and ovaries are all factors involved in the morphology of flowering plants. Some of these characteristics, such

Moriculture

Introduction Cultivation of mulberry plants is known as moriculture. There are about 20 species of mulberry, out of which four are most common- Morus alba, M. indica, M. serrata and M. latifolia. Mulberry can be propagated either via seeds, root- grafts or stem cuttings; the last one is the most common. Cuttings, of about 22-23

Monocotyledons

Monocotyledons, also known as monocots, are grass and grass-like flowering plants (angiosperms) with only one embryonic leaf, or cotyledon, in their seeds (Lilianae sensu Chase & Reveal). They are one of the major groups into which flowering plants have traditionally been classified; the rest of the flowering plants with two cotyledons are classified as dicots.

Monocotyledonous seeds

The number of seed leaves on a plant determines whether it is monocotyledonous. A monocot has one seed leaf whereas a dicot has two. It is critical to distinguish between these two types of plants because their root systems and growth patterns differ. The root system of monocotyledonous plants is more confined and does not

Monocots

Introduction The monocots are one of two major types of flowering plants known as angiosperms, the other being the eudicotyledons (eudicots). There are over 60,000 monocot species, including the most commercially significant plant family, Poaceae (real grasses), and the biggest plant family, Orchidaceae (orchids). Further monocot families include the Liliaceae (lilies), Arecaceae (palms), and Iridaceae

Monocot Seeds

Introduction  Do you know why, despite being flowers, the sunflower and the orchid do not belong to the same group of flowering plants? Some plants generate real seeds (Angiosperms), whereas others do not (Gymnosperms). These two blooming plants are distinguished by the number of cotyledons. In terms of root, stem, and leaf structure, dicot and

Monocot and Dicot Leaf

John Ray in the year 1682 published the classification of flowering plants or angiosperms into two major groups. Later a botanist named Antoine Laurent de Jussieu in 1789, replaced the earlier classifications by a new one. According to which classification of flowering plants were divided into eight major groups, and the largest number of species belonged to

FUNCTIONS OF STEMS

INTRODUCTION The stem of a plant is a long structural component that contains leaves and flowers. A plant’s stem provides support and facilitates in the transportation of resources to all parts of the plant. It also preserves and promotes a plant’s development and growth.  Stems might be a few millimetres long or hundreds of metres
