Question | Answer |
Order organs, tissues, cells, organelles, and organ systems from simplest to most complex | Organelles, cells, tissues, organs, organ systems |
What organism is considered an exception to the cell theory? | Virus |
What is a characteristic viruses have that living things have too? | They contain genetic material |
What does the cell theory state? | Living organisms are made of cells, the most basic structure of life, and come from preexisting cells |
What organelle of a cell can easily be seen with a microscope? | Nucleus |
Which part of the cell contains the cell's genetic material | Nucleus |
Which part of the cell controls the movement of materials into and out of the cell | Cell Membrane |
Which organelle is necessary for photosyntesis | Chloroplast |
Which organelle is only in plant cells | Cytoplasm |
Which structure is made of cellulose | Cell Wall |
Some human body cell groups such as blood and skin cells represent different | Tissues in which similar cells function together |
After switching from high to low power on a compound light microscope the field of view will appear | Larger and brighter |
After switching from low to high power what are some changes that would be evident in the field of view | It would be smaller, and darker |
What does chloroplast do? | Aid in photosyntesis |
What shape is an animal cell | Circle |
What shape is a plant cell | Square |
Why is methylene blue sometimes used in wet mounts | To stain the specimen and make it easier to see |
Why don't we drop the cover slip down on the wet mount | To avoid trapping air bubbles under the cover slip |
What parts of a compound light microscope are used for magnification | Eyepiece, and objective |
Describe organelles in a cell | They have to work together and their activities must be coordinated |
What do ribosomes do? | Make proteins |
The cytoplasm is to the cell as ... is to the ocean | Water |
The nucleus is the cell as the... is to the human | Brain |
The cell membrane is to the cell as the ... is to the Earth | Atmosphere |
What are some ways the image in the field of view is different from the actual specimen | Enlarged, upside down and backwards |
What can damage the lens of a microscope | Using the coarse adjustment on high power |
What is a cell? | A collection of organic matter that is enclosed and separated from its surroundings |
What is an organism? | Something that can live and survive on its own |
What is reproduction? | The process of making new organisms |
What is sexual reproduction? | Cells from two different parents unite to create the first cell of the new organism |
What is asexual reproduction? | The new organism has only one parent, the part of the parent may split off and form a new one, it may divide in half |
What is homeostasis? | How an organism maintains a constant internal environment by "internal feedback mechanisms" |
What is the main use of carbohydrates? | Main source of energy |
What are the building blocks of carbohydrates? | Simple sugars- Glucose |
What are the elements and ratio in carbohydrates? | Carbon (1) : Hydrogen (2) : Oxygen (1) |
What is the main use of lipids? | Energy storage, protection, and insulation |
What is the building block of lipids? | Fatty acids |
What is the main use of nucleic acids? | Store genetic information |
What are the building blocks of nucleic acids? | Nucleotides |
What is the main use of proteins? | To do most of the work in our cells |
What are the building blocks of proteins? | Amino acids |
What is a catalyst? | A substance that speeds up the rate of a chemical reaction |
How do catalysts work? | They lower the activation energy needed in a reaction |
What is an enzyme? | Proteins that act as biological catalysts by lowering the activation energy |
What is a substrate? | The chemical an enzyme is working on to break down or build |
What is the common name for the enzyme substrate complex? | Lock and key model |
What can denature an enzyme? | Temperature or pH that is out of the optimum range |
What is the active site and what is its job? | The active site is where the enzyme meets the substrate |
What is the product? | The substrate after the enzyme lets go of it |
What is chlorophyll? | A pigment (coloured pigment) that captures light energy from he sun and turns it into energy the plant can use, sugar |
What is the xylem? | Tubelike structures that carry water from the roots throughout the plant ("roots to shoots") |
What are stomates? | Little pores/holes/openings on leaves that can open and close |
What is transpiration? | The process by which water passes through a plant from roots to the leaf and then out through the stomates |
What is the phloem? | Tubelike structure that carries food (sugar) from the leaves throughout the plant ("shoots to roots") |
What is the collection of female reproductive organs called? | The pistil |
Describe reproduction in the female reproductive organs once it has been fertilized | The pollen lands on the stigma, which is supported by the style. Embryos are made when the sperm and the egg cell merge. The egg cell is inside the ovule which is inside the ovary. Seeds protect the mature ovule, or the embryo. |
What is the collection of male reproductive organs called? | The stamen |
What is the male sex cell called? | Sperm |
What does the pollen grain contain and how is it produced? | The anthers at the tips of the filaments produce the pollen grain which contains sperm |
Describe the process of fertilization | The pollen grain lands on the stigma, it then creates a pollen tube which goes down the length of the pistil. The sperm cell travels down the pollen tube into the ovule and penetrates the membrane of the egg cell and a single fertilized cell is formed. |
What are the three domains of life? | Eukaryota, Bacteria, Archaea |
What is an organelle? | A small structure inside a cell, a little organ |
What's inside a prokaryotic cell? | Plasma membrane, Cytoplasm, Plasmids, cell wall, capsule, flagella |
What is a plasma membrane? | It separated the inside of the cell from the environment |
What is the cytoplasm? | Jelly like substance inside the cell that fills up the membranes and contains the organelles |
What are plasmids? | A circle of DNA |
What is flagella? | A long whip like extension that helps the cell move |
What's inside of all eukaryotic cells? | Plasma membrane, cytoplasm, nucleus,nucleolus, chromosomes, mitochondria, ribosomes, rough E.R., smooth E.R., Golgi complex, Vacuoles, |
What is the nucleus? | Large, round membrane bound structure inside the cytoplasm that contains the nucleolus, genetic material, and is the control center of the cell |
What does the nucleolus do? | Create ribosomes |
What are chromosomes? | Long thread like structures that contain genes |
What are mitochondria? | They produce energy during cellular respiration, the power house of the cell |
What are ribosomes? | They link amino acids to make proteins and are inside the rough E.R. or just floating around in the cytoplasm |
What is the endoplasmic reticulum? | A system of channels within the cytoplasm that transport materials. The smooth E.R. does not contain ribosomes, and the rough E.R. does contain ribosomes |
What is the golgi complex? | A stack of channels and vacuoles that prepare and secrete proteins for export |
What are vacuoles? | Sac-like structures in the cytoplasm that store food, water, and waste. Plant cells have one large central vacuole and animal cells have multiple |
What are inside only animal cells? | Lysosomes, and centrioles |
What are lysosomes? | Membrane bound sacs that contain digestive enzymes to help get rid of old cell parts |
What are centrioles? | A set of organelles made of micro tubules that help the cell divide during replication |
What are inside only plant cells? | Chloroplasts, and cell wall |
What are chloroplasts? | They contain chlorophyll and are located in the cytoplasm. They aid in photosynthesis |
What is the cell wall? | It protects and shapes the structure and is made up of cellulose? |
