---|---|---|---|---|
What are Eukaryotic cells?
This contains DNA that is organized into a double helix. It is also contained in the nucleus
|
What is Interphase?
This phase is where cell spend the majority of the cell cycle.
|
What are chromosomes?
This is a structure in the nucleus of a cell that consists of a long molecule of DNA that is condensed and tightly coiled around associated proteins.
|
What are Carbohydrates?
The molecule is composed of carbon, hydrogen and oxygen (C-H-O)
|
What is Passive Transport?
This is the process which molecules move across a cell membrane but do not require energy from the cells
|
What are organelles?
Specialized structures within a cell that carries out essential functions of life
|
What is Prophase?
In this phase, chromosomes condense and are more visible. The nuclear membrane disappears.
|
What is a gene?
This is specific location on a chromosome consisting a segment of DNA that codes for a particular protein or RNA molecule that has a function in an organism.
|
What are Lipids?
This organic molecule has a structure of carbon, hydrogen and oxygen that often bond t form fatty acids and glycerols.
|
What is Osmosis?
This is diffusion of water through selectively permeable membrane form and area of greater concentration of water to and area of lesser concentration of water
|
What is the Endoplasmic reticulum?
This is a complex, extensive network that transports materials throughout the cell
|
What is a benign tumor?
This type of tumor is a mass of abnormal cell that remain at the original state. The are harmless
|
What is DNA?
This is considers the "code of life" because it contains the instructions for building each protein that an organism needs.
|
What are Proteins?
These organic molecules are composed of chains of amino acids.
|
What is Diffusion?
This is the spreading out of molecules across a cell membrane until they are equally concentrated.
|
What are plant cells?
The cell wall, the central vacuole and chloroplasts are found only this this type of cell
|
What are stem cells?
These are undifferentiated cells. They are unspecialized cells capable of renewing themselves by cell division
|
What are the Nitrogen bases?
Adenine, Thymine, Cytosine and Guanine.
A,T,C and G |
What are Nucleic Acids?
The organic molecules care and transmit genetic information
|
What is Facilitated Transport
This is the process in which some molecules that are not able to pass directly through a cell membrane are able to enter a cell wall with the aid of transport proteins
|
What are Fungal cells?
This type of cell has a cell wall made of chitin and other polymers instead of cellulose. They have several nuclei.They can not make their own food via photosynthesis.
|
What is Telophase?
In this phase of cell division, a nuclear envelop forms around the chromosomes at each poll of the cell. Cytokinesis begins.
|
What is Transcription?
This process in which a portion of the molecule of DNA is copied int a complementary strand of mRNA.
|
What are Enzymes?
These proteins serve as catalysts (they speed up reactions) in living organisms
|
What is homeostasis?
This is the need for an organism to maintain a constant or stable internal conditions.
