Living Environment Terms Flashcards
ATP
a source of energy that can be used and can be storage for energy
Ribosomes
the place for protein synthesis is taken place on
Nucleus
Storage of genetic information
Vaccine
A weakened version of the virus (NOT A LITTLE OF THE VIRUS)
Guard Cells
Cells that help a plant maintain homeostasis they do this by controlling water loss by opening and closing pores
cell
the basic unit of structure and function
that makes up all organisms
homeostasis
the ability of an organism to maintain a
stable internal environment even when
the external environment changes
cell respiration
the process in which nutrients are
broken apart, releasing the chemical
energy stored in them
organelle
a structure within the cell that carries
out a specific function
tissues
a group of specialized cells that
perform a specific function
organ
a body structure made of different
kinds of tissues combined to perform a
specific function
organ system
several organs that work together to
perform a major function in the body
cytoplasm
the jellylike substance that is between
the cell membrane and the nucleus and
that contains specialized structures
mitochondria
generate energy for cells
Autotrophs
organisms that make their own food
Prokaryotic
Cells with no nucellus or really any parts in them
Eukaryotes
Cells with Nucleuses and Cell-Bound organisms
Cell Membrane
A security system for cells to ensure right materials are entering it
Cell Wells
To protect cells of bad materials
Heterotrouphs
Organisms that depend on other organisms to make their food
Chloroplasts
Only in plants catch sunlight to turn into photosynthesis
Ecological Succession
Process over time of organisms in a ecological community
Biomagnification
Concentration of toxins spreading from organisms
Circulatory System
Delivers nutrients and oxygen to all cell in the body
Digestive System
breaks down food and absorbs them for energy and nutrients
Endocrine System
Controls over hormones; helps with metabolism and responds to stress and mood
Excretory System
Removing wastes; by pissing (not pooping that goes with the digestive)
Integumentary System
Protects the body from outside conditions; the skin is a example as it keeps you warm and regulates water loss
Lymphatic System
To filter lymph in order to help keep the body away from viruses
Immune System
to protect from illnesses
Muscular System
to provide muscles to the body can actually function
Nervous System
Controls actions and what we do
Reproductive System
Allows for people to reproduce and make babies
Respiratory System
Helps us breathe; To take in oxygen and release it
Skeletal System
To provide bones so your body is stable
Cold Blooded
Switches between cold and hot
Warm Blooded
regulates the temperature
Negative Feedback
A condition cause something else to go on in order to equally balance the body out
Positive Feedback
Intensifies the variable instead of responding
Complement System
To help the actions of the immune system
Mast Cell
type of cell that has a bunch of substance, upon spotting and pathogen is releases these substances to weaken the pathogen
Macrophage
Cells that consume pathogens
Cytotoxic T Cell
is a white blood cell that can destroy cells that have been infected, they do this by sending signals so the cells can preform apoptosis.
Apoptosis
An action where a cell self destructs this can be due to a error with genetic coding or if a Cytotoxic T Cell sends signals to make it preform the action
Helper T Cells
Help send signals to Cytotoxic T Cells
B Cells
Makes and Uses antibodies against the pathogens
Antigens
Things that are foreign to the body
Antibiotics
Substances that can destroy Bacteria
Antibodies
Proteins that are in a Y shape that recognizes foreign substances and neutralize them
Memory B Cells
Cells that activate B Cells to fight that there are infected cells in the body
Memory T Cells
Cells that activate T Cells to fight that there are infected cells in the body
Dependant Variable
Whats being collected (ex: pulse rate)
Independent Variable
Variable that isn’t being changed by other factors (ex: someones age)
Passive Transport or Diffusion
Is the movement of molecules from a high concentration to areas of low concentration
Active Transport
Move a molecule from Low to High Concentration (Uses Energy [ATP])
Enzymes
Proteins that increase chemical reaction rate
Differentation
is the process that transforms developing cells into specialized cells
Specialized Cells
Cells that have different jobs and purposes
Nucleotide
A double stranded helix that contains genetic code for a person
Niche
a species’ role in its environment
Biosphere
all of earth’s ecosystem
Biodiversity
A measurement of how big a environment is
What color does water turn into when mixed with IKI
Orange/Yellowish
What color does starch turn into when mixed with IKI
Black
