|
What is a tubular transport system within the cell or to the outside?
|
Endoplasmic Reticulum
|
|
|
What is protoplasm found between the nuclear membrane and the cell membrane?
|
Cytoplasm
|
|
|
What is the basic unit of life?
|
The Cell
|
|
|
_______ is the scientific study of all life forms.
|
Biology
|
|
|
What is the power plant inside the cell which produces energy for cellular function?
|
Mitochondrian
|
|
|
What is the packaging plant, which gathers proteins and carbohydrates in membraneous sacs: in gland cells it releases hormones to the rest of the body
|
Golgi Apparatus
|
|
|
The control center for the cell, surrounded by a double nuclear membrane: it contains the chromosome or genetic blue print for the cell
|
Nucleus
|
|
|
The genetic blueprint found in the nucleus; it contains DNA that makes up the genes, which are the genetic code for the cells, organs, and structure of the body.
|
Chromosome
|
|
|
The holding tank for RNA, the essential acid for the chemical activity of the cell and the chromosome information that permits the manufacture of protein.
|
Nucleolus
|
|
|
_______ is the movement of molecules from an area of high concentration to low concentration.
|
Diffusion
|
|
|
_____ is the process through which cells reproduce themselves by division.
|
Mitosis
|
|
|
Just before prophase begins, genetic material in the nucleus is duplicated (doubled). Them the nuclear membrane and nucleus disappear. The chromosomes (genetic material) shorten visible centrioles appear at opposite ends of the cell, and small fibers start to form between them.
|
Stage 1 of Mitosis-- Prophase
|
|
|
During metophase the spindle fibers attach themselves to the center of the chromosomes (centromeres). The chromosomes are now quite think and visible. They begin to line up at the equator of the cell.
|
State 2 of Mitosis- Metophase
|
|
|
During anaphase, the centromeres divide, and the duplicate pairs of chromosomes separate. The separate pairs then move toward the poles of the cell.
|
Stage 3 of Mitosis- Anaphase
|
|
|
When the chromosomes arrive at the poles, telophase begins. The nuclei re-form, the chromosomes gradually become less visible, and the cell separates to form two new cells. The daughter cells are genetically and physically identical to parent cell except for size.
|
Stage 4 of Mitosis- Telophase
|
|
|
_____ is a process in which a parent cell undergoes two special types of cell division that result in the production of four gametes.
|
Meiosis
|
|
|
Reproductive Cells
|
Gametes
|
|
|
Each daughter cell is called a _____ cell, a cell that contains half the number of chromosomes of the origional parent cell
|
Haploid
|
|
|
____ is the term used to describe the passing of traits from parents to children.
|
Heredity
|
|
|
_____ is the study of how traits are passed on.
|
Genetics
|
|
|
The scientists who study heredity.
|
Geneticists
|
|
|
What determines all of our inherited traits?
|
Genes
|
|
|
What ensures that the offspring has genetic material from both parents?
|
Sexual Reproduction
|
|
|
______ is the means of communication of the body and contains the brain, the spinal cord, and specialized neurons
|
The Nervous System
|
|
|
_____ has the job of transporting nutrients to the cells and removing the cells waste.
|
The Circulatory System
|
|
|
_____ is the breakdown of food into simple molecules so it can be absorbed into the cells
|
Digestion
|
|
|
_____ involves the exchange of the outgoing carbon dioxide from the cells with the incoming air.
|
The Respiratory System
|
|
|
_____ Are responsible for voluntary movement.
|
Skeletal Muscles
|
