- monk,& part of the first punnett squares
- mendle's occupation
- metaphase
- chromatids line up in the middle
- carrier
- an individual who has a gene for a particular trait but does not exhibit the trait himself
- spore
- cell surrounded by a protective covering
- aerobic cellular respertation
- sugar+oxygen --> carbon dioxide+water+energy
- anaerobic respertation
- sugar-->carbon dioxide+energy+ alcohol or lactid acid
- hybrid
- an organism in which both of its factors fro a particular trait are different
- diploid
- a cell or organisim that has 2 of each kind of its chromosome
- turgar pressure
- water pressure inside a plants cell's central vacuole; causes the stiffness of the plant
- interphase
- phase when genes are duplicated before cell division
- gamete
- a cell that contains one of each type of chromosome found in a organism; a egg or a sperm
- mitosis
- division of genetic material
- aerobic cellular respertation
- The process by which cells use oxygen to obtain usable energy from an energy sourse.
- 46
- the normal chromosome number for humans
- tissue
- a group of similar cells tha together perform a specific function
- mitosis & cytokinesis
- the two stages of cell division
- organ
- two or more tissues that work together to perform a specific function
- meisosis
- process which must be involved in sexual reproduction
- genetics
- the study of heredity
- division of labor
- each cell or tissue performs a specialized function
- anaphase
- chromatids split to opposite sides
- x chromosome
- where genes for sex-linked characteristics are usally carried; sex chromosomes found in human females and males
- chlorophyll
- the green pigment that aids in capturing light energy necessary for photosynthesis
- purebread
- organism that is the offspring of parents having the same genetic make-up
- anaerobic cellular respertation
- the process by which cells obtain energy from an energy sourse without using oxygen
- recessive
- the characterisic that is masked when a dominant gene is present
- photosynthesis
- the process that forms simple sugars from carbon dioxide and water, using light energy in the presence of chlorophyll
- y chromosome
- sex chromosoem found in human males but not females
- prophase
- nuclear membrane disapears
- incomplete dominance
- the condition in which different genes are neither dominant nor recessive for a single characteristic
- inherited disorder
- an abnormal traits passed through genes
- cytokinesis
- division of the cell's cytoplasm
- dominant
- the characteristic that is expressed when a recessive gene is present
- haploid
- having one of each type of chromosome
- mitocondrion
- where most cellular respertation occures
- sex-linked trait
- a characteristic that has a gene on the x chromsome but no corresponding gene on the y chromosome
- photosynthesis
- carbon dioxide+water+light energy-->sugar+oxygen
- zygote
- new cell that forms by a union of two gametes
- telophase
- nuclear membrane forms to make new nucleus
