Which of the following is made of cells? a rock a snowflake a raindrop a leaf 16. Match the words with the definition. Organism A living thing. Organelle any of a number of organized or specialized structures within a living cell. Cell Membrane The thin, soft outside surface of an animal cell. Cytoplasm The clear, thick gel inside a cell and the organelles that float in it. Mitochondria Rod-shaped organelles that make energy for the cell. Chloroplasts The organelles in a plant cell that make food. 17. Fill in the blanks with your vocabulary words. The smallest part of a living thing that can carry out the activities needed for life is a cell. Inside each cell are organelles that carry out their own jobs to keep the cell alive. The cell's activities are controlled by the nucleus, or the brain of the cell. Mitochondria are the power plant of the cell. Vacuolesare the storage center of the cell. All of these organelles float in cytoplasm and are surrounded by the cell membrane. A plant cell has an extra layer surrounding it, the cell wall, which gives the cell structure and support. Sort the following characteristics tomatch with the correct protist. Amoeba Moves with Pseudopodia Eats with Pseudopodia Asexual - Binary Fission Euglena Moves with Flagellum Has Eyespot Asexual - Mitosis Eats Protists and does Photosynthesis Paramecium Most Commonly Observed Moves with Cilia Eats with Oral Groove Sexual and Asexual Volvox Lives and Moves in Colony Eats plants and Does Photosynthesis Sexual and Asexual within Colony
