Bud, Small lateral or terminal protuberance on the stem of a vascular plant that may develop into a flower, leaf, or shoot. Buds arise from meristem tissue.

Morphogens are signaling molecules that emanate from a restricted region of a tissue and spread away from their source to form a concentration gradient. As the fate of each cell in the field depends on the concentration of the morphogen signal, the gradient prefigures the pattern of development.

Ecology is the branch of biology which deals with the study of relationships among different organisms as well as to their physical environment. Thus, it includes all the life forms and their surroundings ( biotic and abiotic components). Organism is considered as the functional unit of ecology.

In the yeast, the bud originates from a small protuberance on the parent body, while in hydra the bud arises due to the repeated mitotic division.

Meristems are regions of unspecialised cells in plants that are capable of cell division. Meristems make unspecialised cells that have the potential to become any type of specialised cell. They are only found is certain parts of the plant such as the tip of roots and shoots and in between the xylem and phloem.

Buds are the small part of the vine that rest between the vine's stem and the petiole (leaf stem). Inside the buds contain usually three primordial shoots. These buds appear in the summer of previous growth cycle green and covered in scales.

Interestingly, a flower bud is actually a modified leaf. Some flower buds may be fruit buds as the flower will result in a fruit. Mixed buds contain both the immature leaf structure and flower parts. Leaf buds are often more plump and pointed than flower buds.

Botanically speaking, a fruit is a seed-bearing structure that develops from the ovary of a flowering plant, whereas vegetables are all other plant parts, such as roots, leaves and stems.

In invertebrate biology, an appendage (or outgrowth) is an external body part, or natural prolongation, that protrudes from an organism's body (in vertebrate biology, an example would be a vertebrate's limbs). An appendage is any of the homologous body parts that may extend from a body segment.

Taste buds are sensory organs that are found on your tongue and allow you to experience tastes that are sweet, salty, sour, and bitter. ... Those tiny hairs send messages to the brain about how something tastes, so you know if it's sweet, sour, bitter, or salty.

Biology is the natural science that studies life and living organisms, with the other life sciences its sub-disciplines. Some life sciences focus on a specific type of organism. For example, zoology is the study of animals, while botany is the study of plants.

Ecology, or ecological science, is the branch of biology that studies the relationship of plants and animals to their physical and biological environment. The physical environment includes light and heat or solar radiation, moisture, wind, oxygen, carbon dioxide, nutrients in soil, water and atmosphere.

if you see pods developing with white hairs poking out of them then that's the sign that the plant is a female. if you see round oval balls at the nodes. then that's the sign that the plant is a male. in the flowering stage the differences become much clearer as the white hairs will develop into flowers.

A cotyledon is part of the embryo within the seed of a plant. Often when the seed germinates, or begins to grow, the cotyledon may become the first leaves of the seedling. Botanists use the number of cotyledons present in the seed of a plant as a means of classification.

Reproduction in Bryophyllum occurs asexually through vegetative propagation by leaves. The leaf of Bryophyllum is broad and has notches at its margins. Buds arise from the notches. These buds are called epiphyllous buds.
