2 fibers of cytoskeleton

site of cellular respiration in which fuel molecules are broken down into carbon dioxide and water with release of energy (ATP).

the physical boundary that regulates the flow of materials into and out of the cell.

sticky out layer that provides protection

does not require energy

tiny channels through adjacentcell walls that connect cytoplasm of neighboring cells for communication

Examples of eukaryotes

component of plant cell important for structure and cell movement

English Father of Microscopy, first to see dead cells

ground substance and the biggest part of the where organelles and cellular inclusions are found

said that cells came from pre-existing cells.

model that portrayed the proteins form distinct layers (sandwich)

another type of plastid containing pigment that provides yellow, orange, and red colors

enables the formation of spindle fibers during cell division

Greek word meaning “true”

are smaller and simpler. lacks nucleus and other membrane-bound cells

cell eating

materials diffuse from a region of higher concentration to a region of lower concentration through a special passageways in the membrane

Greek word meaning “before”

generally larger and have more complex structures

circular DNA containing material of bacteria

the organelle occuring in photosynthetic activity. contain the enzyme necessary for photosynthesis plus the green pigment chlorophyll

first person to see live cells in 1665

brings material out of the cell. as a secretory vessicle aproaches the plasma membrane, it fuses with it and releases its contents to the exterior

3 types of osmosis:

Prokaryotic Cell parts:

unique parts of animal cells:

collects and processes materials that are to be exported from the cell. the cell’s collecting and packaging center.

sites where proteins are made

cell’s control center. DNA is housed in the _____.

Label the parts

The levels of biological organization

discovered all plants are composed cells. He was a botanist.

the 2 that proposed the widely accepted model of the plasma membrane

extensive network of parallel membranes that extends throughout the cell’s interior. manufacturing center of the cell

discovered all animals are also made up of cells. He was a German zoologist.

the coating material of plant cell surrounding the plasma membrane. for support and protection of plant cell. composed largely of cellulose

when a cell is placed in a solution with a solute concentration that is higher than that within the cell

Greek word meaning “nucleus”

2 types of bulk transport

bring material into the cell

contains around 40 kinds of enzymes that help digest food, disease-causing bacteria engulfed by white blood cells, worn-out and broken parts of the cell

when a cell is placed in a solution with a solute concentration equal to that inside the cell

confers rigidity and shape to the cell

2 types of endocytosis:

3 types of passive transport

when a cell is placed in a solution with a solute concentration lower than that within the cell

passage of materials across biological membranes

responsible for cytoplasmic streaming or movement of cytoplasm

Parts of eukaryotic cell

site of lipid synthesis

site of protein synthesis. has ribosomes attached to it.

unique parts of plant cell:

contains a variety of materials: water, dissolved salts, ions, pigments, and waste product. the storage part of the cell

Cell membrane is a ____ ______ describing protiens are globular identities, floating in and on it.

model that portrayed proteins are embedded within the bilayer (fluid-mosaic)

movement of water through a selectively permeable membran from a solution with a lower concentration to a solution with a higher concentration. special kind of diffusion

In ____, ___________ and son _________ discovered that the two lenses was the secret for better visualization and magnification of objects.

movement from more concentrated area to less concentrated area. is responsible for movement of materials throughout the cytoplasm and into and out of the cells. movement of substances along a concentrated gradient

Most plant and animal cells ranging from __ um to __ um

hair-like appendage that functions in adhesion

cell drinking

facilitates movement of bacteria

involved in the addition of cellulose to the cell wall

3 tenets of cell theory

Cellular transport mechanisms:

movement is from a lower concentrated area to a higher concentrated area. movement of substances against a concentration gradient.
