CP Biology (L1)
Scientists: Matching: Match the scientist name to the
following statements.
1) Schwann
D) The scientist who concluded that all animals are
composed of cells
2) Hooke
C) Scientist who observed that cork was
composed of tiny hollow boxes that he
called cells
Schleiden
E) The scientist who concluded that all
plants are composed of cells
Van Leewenhoek
A) The first scientist to describe
living cells as seen through a
primitive microscope
Virchow
B) All cells come from pre-existing cells
Eukaryotic V. Prokaryotic cells
List characteristics of each type of cell:
Eukaryotic Cells
1) has nucleus
2) has organelles
3) all cells but bacteria
Prokaryotic Cells
1) no nucleus
2) no organelles (except ribosomes)
3) bacteria
Organization in multicellular organisms:
List the levels of organization starting with the
individual cell and ending with the whole organism
CELL >
ORGAN >
TISSUE >
ORGAN SYSTEM
> ORGANISM.
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
BE ABLE TO LABEL THE PLANT CELL DIAGRAM
Homeostasis and Transport
Diffusion 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,
PASSIVE
and _________ transport which does require energy
from the cell.
ACTIVE
If a cell is placed in a hypotonic solution,
it ________. Water moves into the cell.
SWELLS
If a cell is placed in a hypertonic solution,
it ________. Water moves out of the cell.
SHRINKS
If a cell is placed in an isotonic _solution,
it stays the________.
SAME
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
Cell Theory
• All living things are composed of one
or more cells.
• All cells come from other cells.
• Cells are the basic unit of life.
