Plants in the rain forest have unique adaptations to help them to thrive in the climatic conditions present there. Temperatures in the rain forest are high all year round. Since tropical rain forests are located around the equator they receive direct sunlight. The leaves of the plants here are waxy to protect them from the direct sunlight.
Rain fall is high here and it can get up to 4000 mm per year. Leaves are equipped with drip tips to allow for the easy run off of water after a down pour.
The barks of most trees are also smooth to further facilitate the movement of water to the ground. The trees in the forest grow fast and compete with each other for sunlight. The trees grow very tall and very fast so they have specialized roots called buttress roots that can support them. These roots spread out to support tall trees.
The dense vegetation of the forest prevents much plants from growing under the canopy of the trees. A small number of plant however can survive in this low light environment. The plant that grow under the canopy have large, dark green leaves to make use of the little light that passes through.
The answer is ‘increase…increase’. Rainforests are huge carbon sinks. They take up carbon diode from the atmosphere for <span>their photosynthesis. This regulates the amount of carbon dioxide, a greenhouse gas, in the air and hence reduces global warming. Loss of rainforests causes an increase in carbon dioxide in the atmosphere and this increases the greenhouse effect that is the center of global warming. </span>
<h2>Answer :</h2><h3>Part 1:</h3>
Yes, embryos have leaves which are known as cotyledons.
Plants with two embryonic leaves are termed dicotyledonous ("dicots") .
Plants with one leave are known as monocotyledon.
<h3>Part 2:</h3>
Six (6) Chromosomes.
As embryo is formed from the combination of egg and sperm. If embryo has 12 chromosomes then sperm will have half means 6 chromosomes.
<h3>Part 3:</h3>
Six (6) Chromosomes.
As embryo is formed from the combination of egg and sperm. If embryo has 12 chromosomes then egg of a bean or corn will have half means 6 chromosomes.
The answer is B) ATP production begins with glucose.
Answer:
Plants are extremely important in the lives of people throughout the world. People depend upon plants to satisfy such basic human needs as food, clothing, shelter, and health care. These needs are growing rapidly because of a growing world population, increasing incomes, and urbanization .
Plants provide food directly, of course, and also feed livestock that is then consumed itself. In addition, plants provide the raw materials for many types of pharmaceuticals, as well as tobacco, coffee, alcohol, and other drugs. The fiber industry depends heavily on the products of cotton, and the lumber products industry relies on wood from a wide variety of trees (wood fuel is used primarily in rural areas). Approximately 2.5 billion people in the world still rely on subsistence farming to satisfy their basic needs, while the rest are tied into increasingly complex production and distribution systems to provide food, fiber, fuel, and other plant-derived commodities .
Medicinal plants have been used in healthcare since time immemorial. Studies have been carried out globally to verify their efficacy and some of the findings have led to the production of plant-based medicines. The global market value of medicinal plant products exceeds $100 billion per annum. This paper discusses the role, contributions and usefulness of medicinal plants in tackling the diseases of public health importance, with particular emphasis on the current strategic approaches to disease prevention. A comparison is drawn between the ‘whole population’ and ‘high-risk’ strategies. The usefulness of the common-factor approach as a method of engaging other health promoters in propagating the ideals of medicinal plants is highlighted.
