Govind Singh 8 years, 2 months ago

Dry matter is what remains after all of the water is evaporated out of a feed: grain and fresh or dried forages. Fresh pasture has high water content and will have a lower percentage of dry matter than an equivalent weight of dryer feed, such as hay or grain. Dry matter is an indicator of the amount of nutrients that are available to the animal in a particular feed.

Transpiration is necessary evil. Explain

Posted by Shubham Mehra 8 years, 2 months ago

CBSE > Class 11 > Biology

1 answers

Susmita Sikdar 8 years, 2 months ago

Transpiration is a very important activity as it facilitates the movement of water and minerals up towards the leaves in plants. At the same time If the water loss is more than the uptake of the water by the roots, it can cause wilting and even death of the plant. It is for this reason that Curtis in 1926 had rendered Transpiration as a necessary evil.

Deeshika Yadav 8 years, 2 months ago

Firstly sap from leaves is actively transported to phloem 2nd a hypertonic solution is created between xylem&phloem so water is transported to phloem through osmosis. Pressure is created in phloem so water moves from higher concentration to lower concentration Then sap is actively transported to sink &water is transported back to xylem through osmosis So this is mass flow hypothesis

Kiran Kotwal 8 years, 2 months ago

The pressure Flow Hypothesis also known as Mass Flow Hypothesis is the best supported theory to explain the movement of sap through the phloem.
