Cells
What are the three main types of cells? (Think domains of life)
What is an organelle?
What is a cellular organ or "tiny organ"?
What is the main component of the cell membrane?
What is the phospholipid bilayer?
What is the body's control center that controls homeostasis?
What is the brain?
What is the monomer of DNA?
What is a nucleotide?
Why aren't viruses considered to be alive.
What is:
They are not made of one or more cells.
They cannot reproduce without a host cell.
They cannot maintain homeostasis.
They cannot grow and develop.
What organelle contains DNA?
What is the nucleus?
What is Osmosis?
What is the movement of water over a membrane towards salt?
What is stimulus?
What is a change in the organism's external or internal environment that results in a reaction?
What is DNA? How is it organized in the cell?
What is DNA (Deoxyribonucleic Acid) is the universal genetic code shared by all living things?
What is the double helix of the DNA is tightly coiled into chromosomes?
What are the eukaryotic levels of organization? List them largest to smallest.
What are organism, organ system, organ, tissue, cell, organelle.
What organelles do plants have that animals don't have?
What is the chloroplast and the cell wall? Central vacuole is also an acceptable response.
What is the fluid mosaic model of the cell membrane?
What is fluidity means that the membrane is flexible and can move and mosaic means that it is composed of many different pieces?
What is a positive feedback loop?
What is a reaction that amplifies a change and results in the continuation of a process?
What is an enzyme? How do they work?
What is an enzyme is a protein that catalyses chemical reactions?
Cell theory states three essential qualities of a cell. What are they?
What are all living things are made of cells, cells are the basic unit of life, and all new cells arise from existing cells?
What is the difference between the rough and smooth ER?
What is the rough ER is studded with ribosomes and functions in protein synthesis whereas the smooth ER has no ribosomes and functions in lipid synthesis?
What is the difference between passive and active transport?
What is passive transport moves down a gradient and does not require energy and active transport moves up a gradient and does require energy?
What is a negative feedback loop?
What is a reaction that counteracts an change and results in the end of a process?
What kinds of functions do proteins preform in the cell (3 functions)?
What is act as enzymes, allow for movement, and act as structural support?
What are the tenets of life? List all seven.
Are made of one or more cells
Can maintain homeostasis (Stable state of body conditions)
Use matter and energy
Has a genetic code (DNA/RNA)
Can respond to the environment
Can reproduce (Sexually or Asexually)
Can grow and develop
Which organelles make up the endomembrane system?
What are the nucleus, Rough and Smooth ER, Golgi Apparatus, and vesicles?
How does the surface area to volume ratio of a cell affect cell transport?
What is a set of processes that allow organisms to maintain stable body states, despite internal and external conditions or challenges?
What are the three types of RNA and their functions?
mRNA - Acts as a messenger.
tRNA - Allows the message from the mRNA molecule to be translated allowing for the production of polypeptide chains (proteins).
rRNA - Makes up the two ribosomal subunits.
