You need to identify a plant, but it is winter and the leaves have fallen to the ground and mixed with leaves from other plants. The parts of flowers, fruits, and seed leaves of germinating seeds are not available either. Your best clue to identify the plants as a monocot or a eudicot is to:.A. cut the stem and if the vascular bundles are scattered in the stem, it is a monocot. B. determine if there are parallel xylem tubes in the stem to identify it as a monocot. C. inspect the stem for woody bark, as only eudicots have woody tissue. D. cut the stem and if the vascular bundles are in a distinct ring, it is a monocot. E. determine if the roots lack phloem and xylem to identify it as a monocot.

A.

Explanation: To identify if the stem is monocot or eudicot, when the stem is cut and the vascular bundles are scattered then it is monocot stem but if the vascular bundles are in a definite shape in which it forms one or two broken rings then it is a eudicot stem.

Answer is A. cut the stem and if the vascular bundles are scattered in the stem, it is a monocot.

question#1

ans:

cell is the basic unit of organization of all living things. cells are often called the building block of life and it is the smallest unit of life. the study of cell is called cell biology. cell consists of cytoplasm enclosed within membrane, which contain bio-molecules such as proteins and nucleic acid.

two third of cell is water, which means that two-third of your whole body is water. the rest is the mixture of molecules, mainly proteins, lipids and carbohydrates.

question#2

ans:

organ:

an organ is a group of tissues specialized to form a functional unit. an example is the heart in animals.

organ system:

an organ system is a group of several organs whose functions are synchronized to release an effective action in a living organism. an example is digestive system.

question#3

different systems perform different function at tissue level. for example, the respiratory system facilitates breathing. in the alveoli tissue of the lungs, the exchange of oxygen and carbon dioxide molecules between the air and the bloodstream occurs by passive transport, so that oxygen is taken in and carbon dioxide and water are removed. different systems of the body carry out different functions. for example, your digestive system is responsible for taking in and processing food, while your respiratory system working with your circulatory system is responsible for taking up oxygen and getting rid of carbon dioxide.

question#4

question#5

our body works because of the interactions that happen between organs and organ systems.  

for example:  

the heart to regulate blood flow throughout the body. the blood carries oxygen and nutrients to the cells and carries carbon dioxide and waste away from the cells. body systems work together in maintaining a constant internal environment. when this balance is disrupted, the body systems may not function properly, and human health can suffer.   you start to feel bad.
