Evolution Due to environmental factors, It may not look it, but, needles are leaves, they collect solar radiation to produce glucose through the process of photosynthesis, however, needles are, some would say, evolutionary superior to leaves. Needles themselves hold in more water due to their dense wax coating, they are very difficult for insects and other organisms to eat, one because of their structure, and two because of their acidity, they can catch sunlight all year long due to their winter resilience( they don't fall, during the winter), and they have less surface area for wind to catch, which leaves them better protected from wind than most deciduous trees, however the surface area can also pose a larger problem for less surface area means less sunlight interception, therefore more are needed to compete against regular leaves. But.. I Digress... Plant needles are 'PROBABLY' initially the result of evolution of narrow leaves due to climate or environmental factors.
Sry its so long got carried away! Hope this helps xD
Answer:
The cell membrane is permeable to small solutes to let them easily diffuse in and out of the cells.
Answer:
option c
Explanation:
Vascular plants transport water and nutrients using the vascular bundles, xylem and phloem. Xylem transports the former and phloem the latter
<span>The answer is: molecule; carbohydrate. A six-carbon sugar is an example of a molecule that can join with other molecules to form a carbohydrate such as starch or cellulose. The basic unit of carbohydrate is monosaccharide. A six carbon sugar would be an example of a monosaccharide. And it can join with other simple sugars (monosaccharides) to form polysaccharides, such as starch or cellulose.</span>
