Question
|
Answer
|
|
|
|
organelle
|
tiny cell structures that carry out specific functions within the cell.
|
|
|
|
What are 3 cell theories?
|
1) All things are made of 1 or more cells 2) Cell is the basic unit of organization of living things 3) All cells come from preexisting cells
|
None
|
|
|
What is the basic unit of all living things?
|
cell
|
|
|
|
cell wall
|
a rigid layer of nonliving material that surrounds and protects the cells of plants and some other organisms
|
|
|
|
What is mitosis?
|
regular cell division
|
|
|
|
Where do new living cells come from?
|
from reproduction of existing cells
|
|
|
|
cell membrane
|
the next layer after the cell wall and controls what substances come into and out of a cell
|
|
|
|
What inside cells carries out cell functions?
|
organelles
|
|
|
|
nucleus
|
the center/brain of a cell
|
|
|
|
cytoplasm
|
the region between the cell membrane and the nucleus
|
|
|
|
What part of a plant cell allows the cell to transfer sunlight into energy?
|
chloroplast.
|
|
|
|
Is green, light-trapping pigment in plant chloroplasts which is important in photosynthesis.
|
Chlorophyll
|
|
|
|
mitochondria
|
what converts enenrgy in food molecules to energy the cell can use to carry out its function
|
|
|
|
What are found in only an animal cell?
|
lysomes
|
|
|
|
What shape are animal cells
|
Varied, often rounded...no cell wall...only a membrane.
|
|
|
|
cromatin
|
thin strands of genetic material in the nucleus-directs how grows and divides
|
|
|
|
what is the shape of plant cells?
|
rectangular...rigid cell wall surrounds the cell membrane
|
|
|
|
what type of cell doesnt have a nucleus?
|
prokuriotic cell
|
|
|
|
Maintaining a stable internal environment
|
Homeostasis
|
|
|
|
nuclear membrane
|
a thin membrane with pores that allows certain materials to enter and exit the nucleu
|
|
|
|
Movement of water through a selectively permeable membrane from higher concentration to lower concentration
|
osmosis
|
|
|
|
nucleolus
|
organelle that makes ribosome
|
|
|
|
What are vesicles?
|
vesicles transport and process materials from the endoplasmic materials to the golgi bodies.
|
|
|
|
endoplasmic reticulum
|
passageways taht carry proteins and other materials from one part of the cell to another
|
|
|
|
What does a plant cell have theat a animal cell doesnt?
|
central vacuole,chloroplast,cellwall
|
|
|
|
A group of similar cells that work together to do one job.
|
Tissue
|
|
|
|
ribosome
|
factories attached to endoplasmic recticulum to produce protiens.
|
|
|
|
What is the basic unit of life?
|
Cells
|
|
|
|
A structure such as the heart made up of different types of tissues that work together.
|
Organ
|
|
|
|
golgi body
|
receives proteins and other newly formed materials from the nedoplasmic reticulum package them and distribute them to other parts of the cell
|
|
|
|
What is the cell theory?
|
they come from other living cells the cells make up all living things the functional unit of all living things
|
|
|
|
Process by which plants use light, water and carbon dioxide to produce glucose and Oxygen. CO2 + H2O -> C6H1206 + 02
|
Photosynthesis
|
|

storage area of food, water, waste, and other materials
|
None
|
|
|
lyosome
|
small round structures containing chemicals that break down certain minerals in the cell
|
|
|
|
New cells come from
|
existing cells
|
|
|
|
prokaryote
|
cell with membrane and wall but no nucleus + membrane bound organells. do have ribosomes ( bacteria)
|
|
|
|
eukaryote
|
cell with a highly developed nucleous and organelles (plant and animal cells)
|
|
|
|
cell
|
the basic unit of structure and function in living things
|

|
Cytoskeleton
|
support structure within the cytoplasm, made up of tiny rods and filaments
|
|
|
|
microtubes/microfilaments
|
microtubes: thin hollow protein cylindars microfilaments: thin, solid protein fibers ****microfilaments help support and made the cell
|
None
