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
vacuole
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
First to observe cells
Robert Hooke 1663
None
observed tiny organisms with simple microscope
Anton Van Leeuwenhoek
None
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
