Organelles of plant and animal cells:Which organelles are found in plant cells but not
animal cells?
1) CELL WALL
2) CHLOROPLAST
3) Also – Large centrally located vacuole
Which organelle is found in animal cells?
CENTRIOLES
TERMS TO KNOW: CELLULAR ORGANELLES
1) cellular framework found within the cytoplasm composed of microtubules and microfilaments.
CYTOSKELETON
2) responsible for ATP production.
MITOCHONDRION
3) the flexible boundary between the cell and its environment; allows materials such as water and nutrients to enter the cell, and allow wastes to leave.
CELL MEMBRANE
4) the rigid structure located outside the plasma membrane of plants that provide support and protection for the cell.
CELL WALL
5) is the structure that contains DNA.
NUCLEUS
6) the organelle that makes sugar through photosynthesis.
CHLOROPLAST
7. _____________ is the organelle that assembles cell membrane components (It also moves materials through the cell.
Endoplasmic reticulum
8. ______________ are chlorophyll-containing organelles found in cells of green plants. They are the location of photosynthesis reactions that produce sugars.
Chloroplasts
9) is the structure that stores substances such as wastes, carbohydrates, salts, protein, and water.
VACUOLE
10) is the process by which water molecules diffuse across a cell membrane from an area of high to low concentration.
OSMOSIS
Homeostasis and TransportDiffusion occurs until ______________is reached.
EQUILIBRIUM
The concentration is the ________ throughout.
SAME
There are two ways materials enter the cell:
________ transport which requires no energy from the cell,
PASSIVEand _________ transport which does require energy
from the cell.
ACTIVE
If a cell is placed in a hypertonichypertonic solution,
it ________. Water moves out of the cell.
SHRINKS
MORE TERMS TO KNOW:
1) the pressure that water molecules exert against the cell wall.
TURGOR
2) occurs when cell cytoplasm shrinks away from cell walls and turgor pressure is lost.
PLASMOLYSIS
3) occurs when a cell bursts.
CYTOLYSIS
4) bind to the molecule it transports.
CARRIER PROTEINS
5) the process in which materials are ingested into the cell.
ENDOCYTOSIS
6) the reverse of endocytosis.
EXOCYTOSIS
7) the transport of larger particles, or ingestion of whole cells (“cell-eating”).
PHAGOCYTOSIS
8) the transport of solutes in fluids (“cell- drinking”)
PINOCYTOSIS
