Glencoe Life Science Ch4 Review Cell Reproduction
Question | Answer |
---|---|
a type of reproduction - fission, budding and regeneration - in which a new organism is produced from one parent and has DNA identical to the parent organism. | asexual reproduction |
Structure in a cell's nucleus that contains genetic material. | chromosome |
Cells whose chromosomes occur in pairs. | diploid |
Deoxyribonucleic Acid: The genetic material of all organisms; made up of two twisted strands of sugar-phosphate molecules and nitrogen base. | DNA |
haploid sex cell formed in the female reproductive organs. | egg |
in sexual reproduction the joining of a sperm and egg. | fertilization |
The section of DNA on a chromosome that contains instructions for making specific proteins. | gene |
Cell that has one of each type of chromosome. | haploid |
reproductive process that produces four haploid sex cells from one diploid cell and insures offspring will have the same number of chromosomes as the parent organisms. | meiosis |
Cell process in which the nucleus divides to form two nuclei identical to each other and identical to the orginal nucleus in a series of steps (prophase, metaphase, anaphase and telephase.) | mitosis |
Any permanent change in a gene or chromosome of a cell; may be benficial, harmful, or have little effect on an organism. | mutation |
Ribonucleic Acid; which carries codes for making proteins from the nucleus to the ribosomes. | RNA |
A type of reproduction in which two cells usually an egg and a sperm join to form a zygote which will develope into a new organism with a unique identity. | sexual reproduction |
Haploid sex cells formed in the male reproductive organs. | sperm |
New diploid cell formed when a sperm fertilizes an egg; will divide by mitosis and develop into a new organism. | zygote |
