mitosis and meiosis
what is mitosis
cells that occurs when a parent cell divides to produce two identical daughter cells.
Know the different stages of the Life Cycle of a Cell
G1, S, G2, and M
the chemical formula for cell respiration and what cellular respiration is
C6H12O6 + 6O2 → 6CO2 + 6H2O
how to solve a family pedigree chart for inheritance.
Determine whether the trait is dominant or recessive. If the trait is dominant, one of the parents must have the trait
what is a dominant trait
to the relationship between an observed trait and the two inherited versions of a gene related to that trait
What are the stages of Mitosis?
prophase, prometaphase, metaphase, anaphase, and telophase.
Know the functions of organelles of a cell
store genetic information; mitochondria, which produce chemical energy; and ribosomes, which assemble proteins
the chemical formula for photosynthesis and what photosynthesis is
6CO2 + 6H2O → C6H12O6 + 6O2
how do you know the differences between the boys and the girls?
boys are square girls are circles
what is a recessive trait
a trait that is expressed only when genotype is homozygous
What cells of the body use mitosis?
plants, animals, and fungi
whats 3 differences between a plant and animal cell.
animal is smaller, no cell wall, many valvole.
plant cells, larger, cell wall, one valvole.
the meaning of hypertonic, hypotonic and isotonic solutions
Hypotonic has a lower concentration of fluid, sugars and salt than blood. Hypertonic has a higher concentration of fluid, sugars and salt than blood. Isotonic has similar concentration of fluid, sugars and salt to blood
how to use a punnett square
Step 1: Write out the cross T = tall, t = short Tt x Tt.
Step 2: Draw 2 by 2 Punnett square.
Step 3: Write the alleles for parent 1 on.
the left side of the Punnett square.
Step 4: Write the alleles from parent 2.
what are some same facts about recessive and dominant
A dominant allele produces a dominant phenotype in individuals who have one copy of the allele, which can come from just one parent. For a recessive allele to produce a recessive phenotype, the individual must have two copies, one from each parent.
What is Meiosis?
a type of cell division in sexually reproducing organisms that reduces the number of chromosomes in gametes
what does the animal membrane look like compared to a plant membrane
Animal cells simply have a cell membrane, but no cell wall. Plant Cells have a Cell Wall and a Cell Membrane.
the difference between heterozygous and homozygous genes
Being homozygous for a particular gene means you inherited two identical versions. It's the opposite of a heterozygous genotype, where the alleles are different
what kind of out come on a punnett square should you see
determine the expected percentages of different genotypes in the offspring of two parents
What cells use Meiosis?
germ cells
how are plant and animal cells are alike
they are both eukaryotic cells.
the difference between Genotypes and Phenotypes
An individual's genotype is the combination of alleles that they possess for a specific gene
why are punnett squares useful
helps to predict the variations and probabilities that can come from cross breeding.
what are recessive things
Cleft chin, dimples, and freckles
