The cell is the basic unit of structure and function in living organisms.
Cells come from pre-existing cells
nuclear division that makes exact copies of the bodies cells.
PMAT - (Prophase,Metaphase,Anaphase,Telophase)
cell parts and types of cells
cell parts (organelles)
Cell membrane:regulates what goes in and out of the cell.
Cell Wall:structure of a plant cell.
Nucleus:controls functions of cells and contains genetic material
Cytoplasm:fluid that surround a plants organells
Mitochondrion:converts energy into food for the cell
Chloroplast:Where photosynthesis happens
Plant cells differ from animals in structure and function from:
cells, tissues, organs, organ systems, organisms
Functions of systems
Circulatory:keeps blood,oxygen,and nutrients flowing through the body.
Respiratory:to take in oxygen for the body and spit out carbon dioxide.
Digestive:Turning food into energy for the body.
Nervous:send signals from one cell to another to make the body work.
Excretory:rid the body of wastes.
Skeletal:frame for the body.
Muscular:permits movement of the body.
Integumentary:protects the body from damage.
Endocrine:secretes hormones into the blood stream.
Reproductive:creates an offspring to carry on life of that species.
Immune:protects body form viruses
Internal and External stimuli
response to stimuli:
Presence of light(phototropism,pupil dialotion)
Presence or absence of heat(shivering,sweating/panting,transpiration)
Fear(fight or flight)
Hereditary:passing of genetic instructions from one generation to the next.
Genetic material is given form only one parent.
Offspring are identical (uniform) to the parent and to each other.
Disadvantages-lack of diversity decreases chances of survival of species
Genetic material is donated from two parents
Genetic material from two parents allows for more genetic variation in the offspring
Offspring differ from each parent and from each other.
Advantages-diversity increases chances of survival of species
Dominant vs. Recessive
Genotypes vs. Phenotypes
Homozygous vs. Heterozygous
Cells (Genetic Material)
Inherited traits of organisms are passed from parents to the offspring through genes
Genes code for dominant and recessive traits
Genes determine traits
Genes are composed of DNA
Use dichotomous keys to identify organisms (leaves and/or insects) based on their structures.
Variation within a population or species
External features and physiology (animal examples: appendages, mouth structures, camouflage) (Plant examples: storage of food in a bulb, types of roots, types of leaves, seed dispersal, attraction of pollinators)
