Plant Physiology

The stem is the section of the axis that ascends and bears branches, leaves, flowers, and fruits. It grows from the plumule of a sprouting seed’s embryo. There are nodes and internodes in it. Nodes are the parts of the stem where leaves are born. Internodes, on the other hand, are the areas between two […]

The stigma, along with the style and ovary (often referred to as the stigma-style-ovary system), makes up the pistil, which is a portion of a plant’s gynoecium, or female reproductive organ. The stigma is made up of stigmatic papillae, which have pollen-receptive cells and form the distal section of the style or stylodia. These can

The stem is one of two fundamental structural axes of vascular plants, the other being the root. It keeps leaves, flowers, and fruits alive, transports water and dissolved substances between roots and shoots in the xylem and phloem, stores nutrients, and regenerates new living tissue in the xylem and phloem. A vascular plant’s stem is

Fruits are an important and distinguishing feature of plants (angiosperms). The fruits are the result of reproduction, while the flower is a reproductive unit. Fruits are structures that contain seeds. It grows from a fully matured ovary. They include a lot of vitamins, minerals, and fibre. Humans eat grapes, bananas, papaya, and watermelon, among other

Introduction A flowering plant’s seed is an essential component. They produce a new plant as a result of their actions. They can come in a variety of shapes, colours, and sizes. They come in a variety of shapes and sizes, including spherical, wrinkled, winged, and hairy. They will remain dormant until they acquire enough sunlight,

The female component of a flower is made up of stigma, style, ovary, and ovule, which are all found in a pistil. Pollination and fertilisation were developed or adapted largely for pollination. Sperm is deposited for fertilisation with the ovules in the ovary when the pollen tube (style tissues) grows. The pistil, in general, is

Depending on the number of cotyledons present in the seed, angiosperms are classed as monocots or dicots. The seed is made up of an embryo that is encased in a seed coat that protects it from the elements. A triploid endosperm has been discovered in some seeds. A radicle, an embryo axis, and cotyledons are

Seeds are required for the sexual reproduction of plants. This is exclusively found in angiosperms and gymnosperms, and it is created as a result of sexual reproduction in plants. A seed generated by a plant belonging to the Dicotyledons botanical group is referred to as a Dicotyledonous Seed. Buttercups and butter beans are examples of

Introduction: The existence of nodes and internodes in plant stems, whether above or below ground, distinguishes them (Figure 23.4). Leaves, aerial roots, and flowers link to each other at nodes. An internode is the section of the stem between two nodes. The petiole is the stalk that connects the stem to the leaf base. An

The stigma, along with the style and ovary (often referred to as the stigma-style-ovary system), makes up the pistil, which is a portion of a plant’s gynoecium, or female reproductive organ.
