MULTICELLULAR ORGANISMS The complex multicellular animals and plants perform many different activities in order to exist. More energy is invested in all organisms for their accumulation and distribution of food‚ release of waste matters‚ movement‚ reproduction‚ and coordination of these activities. The different organisms have specialized tissues‚ organs and organ systems that work together for the good of the organisms. Thus the well-being of the whole organism depends on the integration

Both Plants and fungi affect the carbon cycle though they do it in different ways- both of them interfere with it while they are attempting to get food/energy to survive on. Each have adapted so they can live in an environment where they can source enough food to survive. They get these things from different sources so grow in very different conditions in order to survive. Plants live in places with lots of sunlight as well as a place where they can source water whereas fungi can live almost anywhere

Unit One: Animal Structures and Functions‚ Answers to Review Questions Respiratory System 1. Indicate the importance of gas exchange in all living organisms. Respiration is gas exchange (Oxygen and Carbon Dioxide) with the external environment. All living things respire. Gas exchange is important so that cellular respiration can take place and energy can be made for the cells. 2. Distinguish among the terms cellular respiration‚ external respiration and internal respiration

In plants‚ the phragmoplast extends and forms the cell wall. * In plants‚ mitosis occurs only in the meristem tissues. They are located at the tips of roots‚ shoots‚ and in the stem‚ between the xylem and phloem. Why mitosis? 1. Growth. The number of cells within an organism increases by mitosis and this is the basis of growth in multicellular organisms. 2. Cell Replacement. Cells are constantly sloughed off‚ dying and being replaced by new ones

“Modern bananas do not require pollination or fertilization of female ovaries for fruit production” (Burghardt par.4). In grocery stores‚ a cluster of bananas is a “hand” and a single banana on the hand is a finger. The strings in a banana are called Phloem Bundles. They put nutrients in the banana. The banana peel can be eaten but is not very tasty. “The banana split was invented in 1904 by 23-year-old David Evans Strickler‚ an employee at the Tassel Pharmacy soda fountain in Latrobe‚ Pennsylvania”

There are many ways in which substances can move across the cell membrane and in which then helps in the function of the body (cells‚ tissues and organs) overall. There are 3 processes that a substance can move across the membrane‚ theses are diffusion (simple and facilitated)‚ osmosis and active transport. Both diffusion and osmosis are passive processes‚ which mean they do not need energy to occur‚ whereas active transport does require energy. All three processes are involved in many functions
