sucrose synthesis is tightly co‐ordinated with the rates of photosynthetic carbon dioxide fixation and starch synthesis in the chloroplasts. Sucrose is transported from leaves via the phloem‚ to provide the rest of the plant with carbon and energy for growth and storage product synthesis. Sucrose is also unloaded from the phloem in sink organs. It can be hydrolyzed by cell wall inverses and imported into the cells as hexose sugars‚ or taken up intact and metabolized by intracellular inverters or sucrose

Onda‚ Kristal H. TTH 8:30-10:00 am BSAC3 BIOLOGY 1. How plants grow and develop? Just as humans have essential needs for survival‚ all plants require several basic elements to grow and thrive‚ including… Soil minerals (the more nutrient-rich the soil‚ the better the plant will grow) Water Air (carbon dioxide‚ hydrogen and oxygen) Sunlight Proper soil temperature Proper air temperature How much a plant needs of each element initially depends on the plant’s original habitat. For example

Process of Diffusion and its importance in living organisms Diffusion is the movement of molecules or ions down a concentration gradient i.e. from an area of high concentration to an area of low concentration. For a diffusion system to be efficient‚ it should have a large surface area so that high amount of substances can be exchanged at a time. It should also have a thin membrane and a continuous supply of substances‚ as a thin membrane means that the diffusion pathway would be short‚ and the continuous

Lignin-strengthened walls supported the stems as they grew upward and outward‚ in patterns that increased the light-intercepting surface of leaves.

of dollars for destroying all 14 different ash trees (Emerald Ash Borer). The adult stage of the EBA isn’t the worriment‚ however the larva is. The larva of the bug buries in the bark of the trees and eats away at the phloem also known as the inner bark (Emerald Ash Borer). The phloem is similar to a human spine‚ it transports nutrients to support the tree as it grows (Iowa Association of Naturalists). If the larva eats away at this inner bark‚ the tree loses it’s strength and eventually dies. The
