what are the principal parts of a cell ?

it is the molecular bi-layer of phospholipids with the proteins arranged in random

substance that exhibits the properties and the activities of life also known as living material of the cell

it is the cell content outside the nucleus

the most distinct organelle usually situated at the center of the cell bounded by double membrane

serves as routes for the transport of materials between various parts of the cytoplasm rough(ER) with ribosomes smooth (ER)

aggregates the RNA and proteins synthesis in the cell proteins synthesized from free ribosomes are released as enzymes, protein from attached ribosomes are for the use within the cell

serves as storage modification and packaging of secretory production in vesicles

contains hydrolases,which catalyst the digestion of proteins, nucleic acids, some carbohydrates and fats

powerhouse of the cell

double membrane organelles found only in plant cells site of food production (photosynthesis) commonly called "food factory"

small vesicles containing powerful oxidative enzymes for inter converting organic molecules

composed of microtubules located in the centrosome just outside the nucleus

structures used for locomotion

round organelles enclosed by single membrane

bound sacs that function in storage and transport

rigid covering that protects the cell

structures that are specialized for plant cell or animal cell only

process that takes place in the nucleus of a dividing cell

what's the meaning of (PMAT)

cellular process that results in the number of chromosomes in a gamete production cells

Bios means?

Logos means study of?

branch of science that deals with plants

study of structures of living things in a person's body

cleavage of DNA by restriction(RES)

appropriate vector or vehicle which would propagate the recombinant DNA

recombinant plasmid into a host cell

also known as (join together)

process to screen which cells actually contain the gene of interest

privacy structure of the protein

in this technique, a genegun is used to fire DNA coated pellets on plant tissues

process used to transfer plasmid DNA

follows a similar methodology as "heat shock treatment"

Geological eras that represents different periods in Earth's history

longest and oldest geological era

rapid diversification of life as well as the development of early land plants and the first amphibians

often called age of dinosaurs

Age of mammals

This mechanism of evolution was proposed

a change in the genes of plant or animal

effect of change

flow of alleles

occurs during meiosis

closely related organism that are very similar and capable of producing fertile offspring

evolutionary biologists

collection of evolutionary mechanisms

prevent fertilization and zygote formation

two species live in different areas/habitats

different seasons

patterns of courtship is different

mating is physically impossible

egg and sperm prevent fertilization

allow fertilization but nonviable. hybrid zygote forms .

fertilized egg fail to develop

there is abnormal segregation of chromosomes during meiosis

F1 hybrids are normal F2 contains many weak or sterile individuals

evolutionary process by which populations evolved to become district species

preventing gene flow also known as other plase

also known as same place and initially occupy same habitat

known as beside place . geographic neighbors

author writes the "essay of the principles of population"

father of paleontology

who study the principles of geology?

who study the inheritance of acquired characteristics ?

who write the " The origin of species"?

preserved remnants of once living organisms trapped in rocks, tar pits, frozen in ice or embedded in amber

study of development of the anatomy of an organism in it's initial phases of development

anatomy and development of organisms

structures which are different in appearance but have the similar function.

structures that same appearance but different in function

usually reduced and have no function in many organisms

living organisms shared numerous related biochemical molecules , such as DNA ,ATP, Amino acids and enzymes

genes are located in the chromosomes , which are made of DNA or deoxyribonucleic acid

molecules that are used to build up and repair body parts

study of the geographic distributions of organisms.

who is the father of biology

human or animal in early stage of development

transfer plasmid DNA
