Answer:
The phloem carries important sugars, organic compounds, and minerals around a plant. Sap within the phloem simply travels by diffusion between cells and works its way from leaves down to the roots with help from gravity. The phloem is made from cells called 'sieve-tube members' and 'companion cells'.
The temperature-dew point spread will increase with heating and decreasing with cooling
Answer: the residues are connected differently in starch and cellulose.
Explanation:
Starch is formed from alpha glucose, while cellulose is made of beta glucose. The difference in the linkages lends to differences in 3-D structure and function. Starch can be straight or branched and is used as energy storage for plants because it can form compact structures and is easily broken down.
