Science

QuestionAnswer
Cell division of autosomes Metosis
The process where plants convert light energy into chemical energy Photesyntheis
An anaerobic process that breaks down glucose for energy and creates acid and/or alcohol Fermation
Without oxygen Anerobic omosis
The twisted ladder structure that DNA takes Double helix cytokensis
The final stage of the cell cycle where the cytoplasm divides into two new cells Cytokenesis
Type of membrane where some substances can pass through while others cannot Semi permable
Compounds that contain carbon Organic compound
The green pigment in plants that traps sunlight Chlorophill
Structures in the cell membrane that carry substances in and out of the cell Carrier moecules
The movement of molecules from an area of low concentration to an area of high concentration. Active transport
Diffusion of water across a membrane Omosis
The cell grows to mature size during Interphase
During DNA replication,adenine pairs only with Thymine
A substance composed of two elements chemically combined Compound
The reactants for respiration are C6 H12 O6 and O2
The substance that stores energy in cells is ATP
During DNA replication the orginal DNA and the copy of the DNA are held together by a structure called the Centromere
The movement of molecules from an area of high concentration to an area of low concentration without the use of energy is Diffusion
Most chemcial reactions in cells could not take place without Water
A change or mistake in DNA is a Mutation
An organic compound that provides stores energy for the cells is Lipids
Write the CHEMICAL EQUATION for photosynthesis CO2 + H2O SUN /Chlorophyll--> C6 H12 O6 + O2^
The chromosomes line up down the center of the cell Metaphase
Chromosomes become thick and fat Prophase
Nuclear membrane disappears Prophase
The original DNA splits apart from the DNA copy Anaphase
Spindle fibers begin to form Prophase
Cytoplasm pinches off into two distinct cells Telophase
Compare active and passive transport. The difference between active and passive transport is the active energy is used and in passive transport no engergy is used to make molecules move. Active transport is an area of high concentration to an area of low concentration. Passive transport is an
Why is it important for the nuclear membrane to disappear during mitosis? it is important because if it did not ,one cell would hsve two sets of chromosomes snd the other would hsve o chromosomes.Both cells would die. This happen because when it splits it would be messed up.
