Cells// The smallest structural and functional unit of an organism, typically microscopic and consisting of cytoplasm and a nucleus enclosed in a membrane. Microscopic organisms typically consist of a single cell.
What are the differences between plant and a animal cells?// Animal cells do not have a cell wall or chloroplasts but plant cells do. Animal cells are round and irregular in shape while plant cells have fixed, rectangular shapes.
Cell Wall's Function// Cell wall is a tough, rigid layer that surrounds some types of cells. Cell wall is a characteristic feature to cells of plants, bacteria, fungi, algae and some archaea. It is located outside the cell membrane. The major function of the cell wall is to provide rigidity, tensile strength, structural support, protection against mechanical stress and infection. It also aids in diffusion of gases in and out of the cell.
Chloroplasts function// The food producers of the cell. The organelles are only found in plant cells and some protists such as algae. Animal cells do not have chloroplasts. Chloroplasts work to convert light energy of the Sun into sugars that can be used by cells.
Muscle// A tissue composed of fibers capable of contracting to effect bodily movement.
Nerve// Any of the cordlike bundles of fibers made up of neurons through which sensory stimuli and motor impulses pass between the brain or other parts of the central nervous system and the eyes, glands, muscles, and other parts of the body. Nerves form a network.
Bone// The dense, semirigid, porous, calcified connective tissue forming the major portion of the skeleton of most vertebrates. It consists of a dense organic matrix and an inorganic, mineral component.f pathways for conducting information throughout the body.
The relationship between tissues that make up individual organs and the functions the organ performs//
Cells make tissues
Tissues make organs
Organs make the organ system
Organ system makes organism
Organism makes population
Population makes community.
Digestive system// The digestive system consists of the mouth, esophagus, stomach, pancreas, gallbladder, liver, small intestine, large intestine, colon and rectum. The main function of the digestive system is to break down food into smaller molecules that the body can absorb. The digestive system is responsible for many duties in order to achieve the essential function of digestion.
Circulatory system// The circulatory system is made up of the heart, blood and blood vessels known as arteries, capillaries and veins. The heart pumps blood throughout your body through the blood vessels. Blood delivers oxygen and nutrients to cells and carries away carbon dioxide and other waste materials.
Respiratory system// Respiratory system consists of the organs that help to breathe. Respiration also known as breathing is the process which delivers oxygen from the external atmosphere to the body and removes the carbon dioxide from body and expels out. The main parts of the respiratory system and their functions are as follows
- The nostrils
My observations about it is that it is very small and hairy and I am amazed at how much it helps you when eating! It is very small compared to other organisms and survives by feeding and acclimating to conditions others cant.
