SOL Study Book Fifth Grade Living Systems Table of Contents Page 1: Cells Page 2: Plant and animal cells Page 3: Five kingdoms Page 4: Plants Page 5: Animals Page 6: Test questions Cells The basic structure of all organisms is the cell. All living things are made of cells. Cells carry out all life processes. New cells come from existing cells. Using a microscope, many parts of a cell can be seen. Page 1 Plant and Animal Cells Plant and animal cells have distinguishing characteristics: Plant cells tend to be rectangular and have these structures: Nucleus – controls cell activities Cell wall – thick, stiff structure that protects and supports the plant cell Cell membrane – this covering inside the cell wall Vacuole – storage space for food, water, and wastes Chloroplasts – the plant cell’s food factory contains chlorophyll. Cytoplasm – jelly-like substance that surrounds other structures. It is mostly water but contains many important chemicals Animal cells tend to be spherical or irregular and have these structures: Nucleus – controls cell activities Cell membrane – An animal cell’s thin outer covering Vacuole – storage space for food, water and wastes. Animal cells have more vacuoles than plant cells but they are smaller Cytoplasm – jelly-like substance that surrounds other structures. It is mostly water but contains many important chemicals. Page 2 Five Kingdoms Living things can be classified into five kingdoms. Monerans are one-celled organisms with a cell wall, but no nucleus that include bacteria. Protists are one-celled or multi-celled organisms with a nucleus. Examples include paramecium and seaweed. Fungi are many-celled organisms which include yeasts, molds, and mushrooms. Fungi do not make their own food. Plants are many-celled organisms that can be categorized into vascular and nonvascular plants. Plants make their own food. Animals are many-celled organisms which include vertebrates and invertebrates. Animals get their food from other sources. Page 3 Plants Plants can be divided into two groups. Vascular plants have tube-like tissues that move food and water up and down the stem. Because of this tissue, vascular plants tend to be taller. Examples are trees, grasses, and flowers. Vascular plants reproduce either by seeds or spores. Nonvascular plants do not have tubes and tend to be smaller. Mosses and liverworts are examples of nonvascular plants. Most plants are vascular Page 4 Animals The animal kingdom can be divided into two groups. Animals with backbones are called vertebrates and include birds, fish, reptiles, amphibians, and mammals. Animals without backbones are called invertebrates. Sponges, flatworms, anemones, insects, and crustaceans are all invertebrates. Page 5 Test Questions:
