7th Microbiology
| Question | Answer |
|---|---|
| Which two organisms contain chloroplasts and eyespots? | volvox and euglena |
| How do a paramecium and an amoeba obtain food to live? | A paramecium collects food into an oral groove, while an amoeba uses pseudopods to surround food. |
| An athlete is running a race. The athlete’s body needs energy. Which organelle(s) in the athlete’s cells supply the energy for cellular functions? | mitochondrion |
| The cells of a plant help the plant maintain its life functions. What part of a plant cell has the function of producing sugar in the presence of sunlight? | chloroplast |
| Which structures are common to both plant and animal cells? | nucleus, cell wall, cell membrane |
| In which organism can cell walls be found? | grass |
| Tina observed a cell under a microscope. She concluded that it was a plant cell instead of an animal cell. Which structure helped her come to this conclusion? | She saw a chloroplast, which animal cells lack. |
| Which of these structures in a plant cell allows a plant to make food? | chloroplast |
| Which function makes a plant cell different from an animal cell? | ability to convert sunlight into energy |
| How does the cell wall of a plant cell compare to the plasma membrane of an animal cell? | The cell wall provides structure and support; the plasma membrane controls the substances that enter and leave the cell. |
| Pseudopods, flagellum and cilia are the structures in which protists like amoebas, paramecium, euglenas and volvox | provide locomotion |
| Which of the following protist moves by cytoplasmic streaming, surrounds food and engulfs it using pseudopods? | amoeba |
| Which of the following protists moves by a flagellum, known for a unique feature-- an eye spot, some contain chlorophyll and are common in fresh water. | euglena |
| Which of the following protist is a colony of ciliates, some containing chlorophyll. | volvox |
| Which of these must be absorbed by animal cells in order to grow? | nutrients |
| Cells perform many different processes that an organism needs to survive and grow. Which is the MAIN function of the process of cellular respiration? | the release of energy |
| The basic units of structure and function for both plants and animals are | cells |
| Which function makes a plant cell different from an animal cell? | ability to convert sunlight into energy |
| Euglenas are capable of heterotrophic behavior. How does a euglena differ from an amoeba in the way it gathers food? | A euglena takes food in through its gullet and deposits it into a food vacuole. |
| All organisms process nutrients. Which sentence BEST describes how plants and animals process nutrients similarly? | Cells break down nutrients into usable forms. |
| Oscar & Andre used a microscope to observe a sample of pond water & drew an ex of each type of organism they saw. they compared their drawings,discovered drawings of a euglena & paramecium alike, their amoeba drawings very different shapes. What are 2 t | eating and moving |
| A student used the dimmest setting on a light microscope to observe a euglena and an amoeba. The student shined a narrow beam of light at the top of the cover slip. She observed that the euglena swam up toward the light but the amoeba did not. She knew th | An amoeba is unable to respond to light. |
| A euglena cell has a structure called an eyespot that detects light. A paramecium does not have an eyespot, and so it cannot detect light. Why doesn’t a paramecium need an eyespot? | A paramecium does not photosynthesize its own food. |
| A euglena has a flagellum and a paramecium has cilia. Both types of organelles help these organisms move through the water. However, a paramecium can also use its cilia to perform another task. What is this task? | obtain food |
| Which protist is a bi-flagellate autotroph? | volvox |
| An amoeba uses a sugar molecule during metabolic activity. It loses energy to the environment as a result. The transformation of energy from the sugar molecule to environmental energy can be described as a transformation between which of these? | chemical energy to thermal energy |
| Which of the following describes asexual reproduction? | binary fission in an amoeba |
| A student draws a picture of an amoeba. What do an amoeba and a human have in common? |
