Term
What type of cellular reproduction does bacteria undergo?
Definition
Binary fission
Term
This is the sum of all chemical relations that occur in an organism. In a cell reaction takes place in a series of steps called metabolic pathways progressing from a stand point of high energy to low energy.
Definition
Metabolism
Term
Hydrophobic Tails
Definition
Water fearing called NON-POLAR
Term
Has a Nucleus. More complex, contain organelles surrounded by membranes, most living organisms.
Definition
Eukaryotic Cell
Term
A recessive trait will be expressed if?
Definition
Both alleles are recessive.

Definition
Calvin Cycle
Term
Intracellular digestion takes place.
Definition
Liposome

Cellular Membrane
Definition
This is the most important part to the cell (cell protection). Made up of a phospholipid bilayer and proteins.
Term
Sexual Reproduction
Definition
The process that determines how reproductive cells divide in a sexually reproducing organism is called Meiosis I &II
Term
These are particular types of proteins nearly all cellular function is catalyzed by some type of enzyme.
Definition
Enzymes
Term
No nucleus defined nucleus organelles, few internal structures, do not have structures surrounded by membranes, 1 celled organism, BACTERIA
Definition
Prokaryotic Cell
Term
At which phase of meiosis does crossing over occur?
Definition
Prophase I
Term
Which of the following biologic macromolecules are most important to the cellular membrane?
Definition
Phospholipids
Term
Long chains of polymers of sugar. Their purpose is storage, structural and energy
Definition
Carbohydrates
Term
What is the primary cause of water molecules moving into or out of the cell?
Definition
Water molecule pressure gradient along the cell membrane.
Term
Cellular Reproduction
Definition
Cells produce in 3 different processes and fall into 2 categories sexual and asexual (splits daughters)
Term
Photosynthesis
Definition
light reactions solar energy to chemical energy.
Term
How could water be boiled at room tempature?
Definition
Lower the pressure
Term
Why is DNA important for metabolic activities of the cell?
Definition
Controls syntheisi of enzymes.
Term
Chromosomes
Definition
Binds to the plasma membrane where it replicates, cell grow, pinches in 2 and produces 2 identical cells.
Term
In which organelle does transcription begin?
Definition
mRNA
Term
What is the important characteristic of water?
Definition
Polarity of the hydrogen-oxygen bonds.
Term
Cell
Definition
2 types of cell and they are referred as solids. All living things are made up of cells and they are the smallest working units of all living things.
Term
Cytoplasma
Definition
A watery suspension called cytosol inside the cell that the organelles are suspended.
Term
The idea of evolution Science process is?
Definition
Hypotheses - a statement
Term
What is the probability that a recessive trait would be expressed in offspring if 2 parents who are both heterozygous for the desired trait were crossed?
Definition
25%
Term
Contains DNA of the cell in organized masses called chromosomes which contain all the material for the regeneration of the cell as well as instruction for the function of the cell.
Definition
Nucleus
Term
Fatty acids phospholipides and steriods
Definition
Lipids
Term
Hydrophilic Heads
Definition
Water liking called POLAR
Term
Goli Apparatus
Definition
Inside the cell packaging processing and shipping organelle transports materials from the ER throughout the cell.
Term
What process is responsibile for actively transporting small particles across the cell membrane?
Definition
Pinocytosis
Term
What is Biology?
Definition
Study of life
Term
If the dominant allele is present?
Definition
The phenotype expressed will be dominant.
Term
Steroids
Definition
last of the lipids, component of membrane, precursors to significant hormones
Term
Which structure is the primary control center for the cellular activities?
Definition
Nucleus
Term
What cellular organelle is the site of the catabolic pathway leading to cellular energy production?
Definition
Mitochondrion
Term
These are membrane enclosed structures that have various function depending on the cell type. Plants have a central area that functions in storage, waste, disposal, protection and hydrolysis.
Definition
Vacuoles
Term
Membranous organelle found attached to the nuclear membrane and consist of 2 continuous parts--rough and smooth.
Definition
Endoplasmic Reticulum (ER)
Term
This is found in eukaryotic cells and are the site of respiration
Definition
Mitochondria
Term
A diploid germ cell containing 72 chromosomes under goes meiosis. How many chromosomes will be in each gamete?
Definition
36
Term
These are found in plants and are the site of photosynthesis.
Definition
Chlorplasts
Term
Dominant Allele
Definition
The letter is capitalized
Term
Most significant contributor to cellular function. They are polymers of 20 molecules called amino acids. They are the largest of the biological molecules.
Definition
Proteins
Term
What is a benefit of water's ability to make hydrogen bonds?
Definition
High specific heat.
Term
What is the primary purpose of the flagella on the surface of the cells?
Definition
Movement of the cell.
Term
These are components of the molecule of inheritance - DNA & RNA used in the transfer and as a messenger in most species of the genetic code.
Definition
Necleir Acids
Term
Mitosis
Definition
Cell division occurs in 5 stages: prophase, metaphase, anaphase, telophase, cytokiness
Term
Cellular Respiration energy
