Plant Structure and Growth
Roots anchor, the plant, ingest minerals and water, direct water and supplements, and store food. These are two kinds of root frameworks.
Plant Life Cycle
Plants are part of the PLANT KINGDOM, which is one of the five kingdoms of life. Plants are divided into smaller classes based on common characteristics. Certain characteristics are shared by all plants. They are made up of a large number of cells. They also make their own food through a chemical process called photosynthesis, which involves the use of water, carbon dioxide, and solar energy. They pump life-giving oxygen into the air as a by-product.
Life Cycle of Plants
All the organisms that belong to the Kingdom Plantae are known as plants. They are multicellular and eukaryotic and can synthesize their food by photosynthesis, known as autotrophic organisms. They are classified based on certain characteristics, such as the plants bear flowers; some have only naked seeds and do not contain flowers. Some plants neither have seeds nor flowers, such as ferns and mosses.
Plant Morphology and Anatomy
The study of life and organisms is biology. The cell is recognized as the basic unit of life by biology. From ancient Greek, biology is recognized. Modern biology deals with the recent developments in Science.
Explain the growth of hypha.
The thallus of fleshy fungus contains long filamentous cells called as hyphae. This is responsible for vegetative growth of fungus. In favorable environmental conditions these hyphae undergo repeated branching which is known as mycelium.
Hyphae are produced by germination of vegetative spores produced by fungus. Hyphae contains cell wall, cytoplasm, nuclei, ribosomes and other cell organelles which are required for fungal growth, nutrient absorption and transportation.
Extension of Cell walls and internal components from the tips causes growth of hyphae. It is associated with internal organelle called spitzenkorper. This is responsible for formation of new cell wall and membrane structures. Golgi bodies produce apical vesicles containing enzymes required for cell wall lysis. Hyphae grow continuously at their tips by releasing enzymes which facilitate extension of tip. GTP activates glucan synthetase by forming the characteristic structure known as spitzenkorper and release them along hyphae apex.
As these spitzenkorper move hyphae get extended at its tip via the release of the vesicle contents, which form the cell wall, and the vesicle membranes, which create a new cell membrane.
