For our bodies and those of most other animals, the surface area-to-volume ratio is maintained by increasing the number of cells and not the size of each cell. What features of even the largest of animal bodies allow the cells access to oxygen, nutrients, and other resources? (choose all that apply; more than one answer may be correct) Specialized structures that have evolved within the organism provide synthetic substitutes to eliminate the need to exchange with the environment. Specialized structures that may be extensively branched or folded enable exchange with the environment. In organisms with body plans that are more complex than hydra or tapeworm, harmless blood-borne microorganisms provide exchange surfaces for nutrient and gas transfer to body cells. Internal body fluids, such as interstitial fluid, link surfaces for nutrient and gas exchange to body cells. Cells in areas of importance in the body are increased in size where nutrient exchange with the environment is vital.

The cell is the basic unit of all living things. Some organisms like Amoeba and bacteria are only one cell. Viruses are sub-cellular. Plants and animals are multicellular. Analyze how this fact is important when considering how different organism feed, respire, and excrete. Give two examples for each characteristic and use a multi- cellular organism and a uni-cellular (one-celled) organism to compare.
Remember that your body is made up of millions of cells! Cells work together and perform various functions depending on their cell type. It is important to understand that cells are a part of an organism's levels of organization. Fill in the following chart and draw a picture that represents each level
While eukaryotic cells are generally larger than prokaryotic cells, metabolic requirements place upper limits on how large eukaryotic cells can become. Which of the following statements does not accurately describe this? As multicellular organisms grow in size, they do not have larger cells; rather, they have a larger number of cells. As a cell increases in size, the surface area grows faster than volume. If a cell is too large, there will not be enough surface area for the exchange or elimination of oxygen, nutrients, and wastes. The surface area to volume ratio must remain as large as possible
How does the scaling of surface area to volume ratio limit the size of cells? body cells cannot be too small because they would not be able to get oxygen across their membranes fast enough to accommodate all of their mitochondria "body cells cannot be to small because they would not have enough surface area to get rid of CO2, urea, and other nitrogenous wastes fast enough body cells cannot be too large because organelles and enzymes deep in the interior would not be able to get enough O2 or nutrients
Tissues, Organs, & Systems Multi-cellular organisms have many cells that work together in specific ways, each group performing certain functions. When each group does its part, the organism gets everything that it needs. A Tissue is a large group of cells that all have the same purpose or function. Each kind of cell has unique characteristics such as shape, size, flexibility, color and texture. Nerve cell combined with other nerve cell to make nerve tissue. Muscle cell combined with other muscle cell to make muscle tissue. Bone cell combine with other bone cell to make bone tissue. An Organ is a group of tissues that work together to do a certain job for the body. Some of the human body’s organs include the stomach, lungs, heart, kidneys, brainand liver. Some of a plant’s organs include roots, stems, fruit and leaves. When several different organs join to meet the organism’s needs, they are working together in an organ system. There are several different organ systems constantly…
Which of these statements is true about multicellular organisms? (a) each section of an organism is made of a special type of cells that perform one specific function (b) the tissues within an organism each contain a variety of cell types, so that the tissue can form any kind of organ (c) cells are equipped with a variety of organelles so that the cells all work independently of one another (d) the systems within an organism work together to support the organism's overall function
Which of the following statements correctly describes gap junctions and plasmodesmata? These linkages connect the cytoskeletons of adjacent cells. They both are present in animal cells. They facilitate the movement of cells over connective tissue. They are large pores linking adjacent cells.
Why is there an upper limit on how large cells can become? Large cells have a small volume relative to their surface area Large cells cannot effectively diffuse enough nutrients and gases across the cell membrane Large cells Cannot form a phospholipid bilayer Large cells cannot separate an internal and external environment Organisms larger than about 1 mm cannot maintain homeostasis
Compare and contrast: Adaptation and acclimatization Conformation vs. Regulation Diffusion, facilitated transport and active transport metabolic rates of large and small animals. convection, conduction, radiation and evaporation
Which of the following statements is NOT TRUE about tissues? A. The extracellular matrix of blood tissue is the plasma B. In adipose tissue, tiny cells are surrounded by very thick extra cellular matrix which is where all the fat is located C. Epithelial cells sometimes have cilia like the ones used in comb jellies and placozoans D. Nervous Tissue has only one cell type, the neuron
Some human body cells are shown in the diagrams below. Cells from skin Blood cells Cells from lining of bladder Cells from lining of trachea These groups of cells represent different- tissues in which similar cells function together organs that help carry out a specific life function systems that are responsible for a specific life function O organelles that carry out different life functions
Following are the charact ristics of organoids, except: Organoids are in vitro 3D clusters of cells deriving exclusively from primary tissue or stem cells Organoids are capable of self-renewal and self-organization. 2D monolayer cultures are much closer to the in vivo situation than the organoids Spatially restricted cell-fate decisions contribute to self-organization in organoids.
