Vocabulary Terminology for Chapter 7 in Friendly Biology
Question or Term | Answer or Definition |
---|---|
Cytology | Study of cells |
Dutch Scientist who discovered cells in the 1600s | Antonie Van Leeuwenhoek |
What did Antonie think cells looked like | jail cells |
organelles | All the components or "little organs"that make up a cell are called |
cell membrane | membrane or skin that covers a cell |
phospholipid bilayer | what the cell membrane consists of |
The Lipid layer is | hydrophobic |
The Phosphate groups are | hydrophilic |
cell membrane function | the ability to allow certain substances to pass through but not all, also known as semi-permeable |
cell wall | Extra layer of protection around a plant's cell |
Made of cellulose, which are long strings of glucose molecules | cell wall |
Cell wall function | strength and support or skeletal framework for the plant cell |
softwoods are | Trees that have thin cell walls and grow quickly |
hardwoods are | Trees that have thick cell walls and grow slowly |
cell organelle that functions like the brain is | the nucleus |
Some nuclei have a membrane known as | nuclear membrane or nuclear envelope |
Eukaryotes | organisms that do have a nuclear membrane or envelope (Eu=do) |
Prokaryotes | organisms that have no nuclear membrane or envelope (Pro=No) |
prokaryotic organism example | bacteria |
Chromosomes (colored bodies) | The structures within the nucleus of a cell which hold the instructions for the cell |
Chromo | colored |
-somes | bodies |
The number of & information on each chromosome is | specific for each living thing |
Chromosomes consist of smaller subunits or "recipes" known as | genes |
Genes code an organism's | features, traits, or characteristics |
Mitochondrion function | the cell's power plant |
What fuels the Mitochondrion | glucose |
C6H12O6 | chemical formula for glucose |
Mitochondrion are shaped like | beans |
Cristae | Inner membrane of the mitochondrion |
Respiration | the process whereby glucose is converted into energy in the form of ATP in the mitochondrion |
ATP is the abbreviation for | adenosine triphosphate |
In the presence of oxygen, one glucose molecule will yield | 38 ATPs |
With no oxygen present, one glucose molecule can only yield | 2 ATPs |
aerobic respiration | respiration in the presence of oxygen |
anaerobic respiration | respiration not in the presence of oxygen |
The two main uses for ATPs are to allow for | movement and heat production |
