What is a gene?
Piece of DNA that codes for a protein
200
What compound is necessary for life to happen?
H2O or water
200
What kingdom has no cell wall?
Animalia

In the huge diversity of cell types, is cell structure related to its function?
Yes, this an important concept in biology.
200
By what process does water naturally move across the cell membrane?
Osmosis
200
What is mitosis?
Cell division for cell growth and repair in eukaryotes
300
How do you recognize an ion?
It has a charge, either negative or positive e.g. Na+, Cl-. It is the active form of an element.
300
What kingdom is entirely autotrophic and has cellulose cell walls?
Plantae
300
What 3 parts do cells have?
plasma membrane, cytoplasm, nucleoid or nucleus containing DNA
300
How does sugar naturally move through the cell membrane?
Facilitated Diffusion; has the help of a protein channel.
300
What is meiosis?
Reduction cell division to make eggs and sperm in sexual reproduction in eukaryotes.
400
What important process in some plants, green bacteria and protists, makes food for the food chain and oxygen to breathe?
Photosynthesis: sunlight + chlorophyll carbon dioxide + water --------> sugar and oxygen
400
What kingdom is heterotrophic and has chitin in its cell walls?
Fungi
400
Which organelle does photosynthesis in plant cells?
Chloroplast
400
What does "isotonic" mean and why is it important to red blood cells?
Keeps the cell from shrinking or exploding so it can carry oxygen efficiently.
400
How is binary fission different from mitosis?
Binary fission-asexual reproduction in bacteria (prokaryotes) Mitosis-asexual reproduction for growth and repair in eukaryotes
500
What process makes energy (in the presence of air) in all organisms?
Cellular Respiration: sugar + oxygen--> carbon dioxide + water + Energy (ATP)
500
Which kingdom is microscopic and eukaryotic?
Protista
500
Which organelle does cellular respiration in almost all cells?
Mitochondrion
500
How is active transport different from passive transport?
Goes from less to more (not more to less). Is a pump that uses energy (ATP)
500
What are the jobs of DNA?
Controls cell metabolism Make proteins Transmits genetic traits from one generation to another.
