cells Flashcards
how did Robert Hook discover the cell
in a slice of cork he discovered a box like plant cell
Who was Anthony Van Leewenhock
developed and improve on many high microscopes also he was the first to observe and describe single celled organisms
what’s the cell theory
1: all organisms are made of one or more cells
2: The cell is the basic unit of life
3: New cells come from pre-existing cells
are the two types of cells
prokaryotic and eukaryotic
what do red cells do
Fight infection in the body
identify two single celled organisms
amoeba and Ugluina.
identify two structures that are found in plant cells but not found in animal cells
chloroplast in cell wall
what is the function of the nucleus
responsible for making ribosomes
what is made of the mitochondria
Energy
what develops from putting cells together
tissues
what is the purpose of photosynthesis
to create food for the plant
what is the purpose of the cell membrane? How many layers is it?
allow certain materials to pass into the cell it has three layers
what does the word organelle mean
Little organs
describe the contents of the nucleus
chromosomes that contain genetic info
what makes up the cytoplasm
Energy that is in the cell
why do you lysosomes contain enzymes
to digest small particles
what is the purpose of Golgi complex
package and ship out of the cell
with the reactants and products of photosynthesis
reactance: light, water, carbon dioxide products: oxygen, glucose
how do muscles work
nerves and axons
Who discovered the cell
Robert Hook
DNA
makes up jeans
genotype
genetic makeup of an organism
Allele
form of a gene
recessive
represented by lowercase
dominant
represented by an uppercase letter
when a dominant and recessive gene come together what is it called
heterozygous
went to dominate or two recessive genes come together what is it called
homozygous
phenotype
physical trait in organism
what is heredity mean
passing down of traits from parent to child
describe the relationship between genes chromosomes in DNA
Jeans are in DNA which can be located on chromosomes
identifying to Skype to processes that allow DNI to be inherited by the next-generation
meiosis and crossing over
chromosomes
hereditary units of an organism
Genes
part of the DNA containing the genetic code arranged on to chromosomes
alleles
two forms of a gene for each characteristics
