The coordination in plants is done by the chemical substances called phytohormones. The nervous system and endocrine system together bring coordination in animals. Plants do not have specific glands to secrete hormones, instead, hormones are found in the cells of root and shoot.

effect on plant growth. In plant development: The emergence of the seedling. Light affects both the orientation of the seedling and its form. When a seed germinates below the soil surface, the plumule may emerge bent over, thus protecting its delicate tip, only to straighten out when exposed to light (the curvature is retained if the shoot….

Figure 7.12. 1: ATP Synthase: ATP synthase is a complex, molecular machine that uses a proton (H+) gradient to form ATP from ADP and inorganic phosphate (Pi). Chemiosmosis is used to generate 90 percent of the ATP made during aerobic glucose catabolism. The production of ATP using the process of chemiosmosis in mitochondria is called oxidative.

Chloroplasts visible in the cells of Bryum capillare, a type of moss. A chloroplast ( / ˈklɔːrəˌplæst, - plɑːst /) [1] [2] is a type of membrane-bound organelle known as a plastid that conducts photosynthesis mostly in plant and algal cells. The photosynthetic pigment chlorophyll captures the energy from sunlight, converts it, and.

Moreover, the winds move in the vertical direction in this region. Also the convergence zone of the trade winds near the coastal areas is extremely weak. As a result, cyclones are not formed. Therefore, tropical cyclones occurrarely in Brazil. Concept: Climate of Brazil.

A common type of short circuit occurs when the positive and negative terminals of a battery are connected with a low-resistance conductor, like a wire. With a low resistance in the connection, a high current will flow, causing the delivery of a large amount of energy in a short period of time.

Ans: During the storage of grains both biotic and abiotic factors cause losses to the grain. Biotic factors such as insects, rodents, mites, fungi, bacteria, etc. and various abiotic factors such as moisture, temperature, lack of sunlight, etc. are responsible for losses of grains.
