SPECIFY THE FUNCTIONS OF EACH
(STEM_BIO11/12-IA-C-4)
Cell types

Review
Rearrange the following words according to their
complexity.
ORGANS
CELLS
TISSUES
ORGAN-SYSTEMS
ORGANISM

How did the prokaryotes
evolved into multi-cellular
organisms?

These cells are long and
can contract quickly.
They contain lots of
mitochondria to produce
energy required for
movement.
MUSCLE CELLS
01
Smooth
Muscle Cell
Skeletal Muscle Cells

Cardiac Muscle Cells
Smooth Muscle Cells

Have bands of protein and are arranged in
fibers to help them run along the length of
the muscles.

Very thin and
thread-like with lots
of nerve endings
(dendrites) at either
end.
NERVE CELL
02
NEURON

Transmit electrical impulses around
the body, and very connected to
other nerve cells sending messages
to the brain, so the body responds in
a particular way.
NERVE CELL - FUNCTION
02

Made in the testes
and can be found
in semen that is
long and thin and
have tail.
SPERM CELL
03

Can swim with the
help of the tail
that helps it to
find egg cells to
fertilize it.
SPERM CELL
03

Made in the ovaries of a
female that is the largest,
roundest human cell,
surrounded by a protective
layer of cells that provides
nutrients.
EGG CELL
04

Found lining certain tubes
in the body, including the
trachea and bronchi, which
lead to the lungs that have
cilia (tiny hair like
structures) on the surface
to sweep particles away.
CILIATED EPITHELIAL CELL
05

Protect the
lungs from
microorganisms
and dust by
moving them up
the airway.
CILIATED EPITHELIAL CELL
05

Made in the
bone marrow
biconcave
large surface
area and easily
travels in BV.
RED BLOOD CELLS
06

Travel inside the
blood vessels
carrying oxygen
to all cells so it
can be used for
respiration.
RED BLOOD CELLS
06

Help fight
pathogens
which cause
diseases.
WHITE BLOOD CELLS
07

Located at the
top of any leaf.
Packed full of
chloroplasts
PALISADE CELL
08

Its chloroplasts,
which are full of
a pigment called
chlorophyll is
responsible for
photosynthesis.
PALISADE CELL
08

Found inside plants
which is very long
and join end to end
and have only very
few subcellular
structures.
PHLOEM
09

Transport food
(mainly dissolved
sugars) around the
plant from the
green parts.
PHLOEM
09

composed of
conjoined dead
cells.
Carry water and
mineral from the
roots to stem and
leaves.
XYLEM
10

Attached to
plant roots
which is long
and thin with a
large surface
area.
ROOT HAIR CELLS
10

Long and thin and
have a large
surface area to
help with the
absorption of
water and
minerals.
ROOT HAIR CELLS
10

Unicellular vs. Multicellular
CELL
SPECIALIZATION
Specialized cells perform
specialized functions in
multicellular organisms

ACTIVITY 2

video then answer
the guide questions.

answer the following questions.
1. What are stem cells?
2. What is the special capability of stem
cells?
3. What are the 3 types of stem cells?
4. How will stem cell technology improve
our lives?

cells is found in females and is
needed for reproduction?
A. egg cell

hemoglobin to help them carry
oxygen.
B. They have long connections that transmit
messages quickly.
C. They have a large amount of cytoplasm.
D. None of these.
