What are some types of living
things???
objectives
• Classify things into living and nonliving things.
• Compare and contrast between living and
nonliving things(give example ).
• Recognize the needs of living things.
• Identify the meaning of organism.
• Identify the meaning and types of the cell.
• Identify the main parts of the plant cell and its
function.
• Identify the main parts of the animal cell and its
function.
• recognize methods to observe living things.
The importance of animals homes.
• Read the fast fact p. 50
• Where does a seal live?
• What might a frog use as a home?
• Why do animals live where they do?
• What do shelters provide for the living things?
Living and non-living
• Living things: any thing needs food, water, and air.
• Nonliving things: : any thing dose NOT needs food,
water, and air.
• Once living things are the things that were
living after that become nonliving.
• Any living thing is an organism.
• What is the difference between the cat and
plant???(both are living things).
• living things reproduce: it makes more of its
kids.( cat: kittens – plants: seeds ).
• Living things react to changes around them.
( cat run away ).
• Living things need energy to grow and move.
• People and animals get energy from food, but
plants get energy from the sun.
Living and nonliving things
• Living things
• A living thing can
reproduce.
• It uses energy to grow.
Plants use the energy
from the sun to make
food.
• They react to changes
in the environment.
(examples)
Any living thing is an
organism
• Nonliving things
• They can’t reproduce
• Don’t grow or
change
• Don’t react to
changes in the
environment.
From what this wall is made of?
Types of cells
15
• Animal cell
• Plant cell
Nucleus
Cytoplasm
Vacuole
Cell
Membrane
Chloroplast
Cell Wall
cells
• All living things made up of parts( face- hand- leg…), and these parts made up of a small parts called
cells.
• Cells are a tiny building block.
• it is the smallest unit of a living thing.
• Most cells can not been seen without a
microscope.
• Plant cells can be different in shape and size, but
they have the same parts.
• Are some cells more important than other cells?
explain.
• Each cell in an organism has its own job; like in
plant: leaf, roots, and stem.
• All the cells in an organism work with together
to help organism survive.
Parts of plant cells
• Plant cell
1. Cell wall
2. Cell membrane
3. Nucleus
4. Cytoplasm
5. Vacuoles
6. Chloroplasts
Functions of the parts
• Cell wall: it gives the cell its shape.
• Cell membrane: it keeps not needed substances
out of the cell. It protects the parts inside the cell.
• Cytoplasm: keeps cell parts in place.
• Chloroplasts: make food to enable a plant to
get energy it needs to stay a live.
• Nucleus: tells the rest of the cell parts how to
do their jobs, just like the brain in human.
• Vacuole: a storage location in cells
Animal cell
• Animals made up from cells.
• Each cell has its own job:
– Skin cells
protect it from the outside.
– Muscles cells
join together to make muscle
for moving.
Parts of the animal cells
• Animals cells have 4 main parts:
– Cell membrane
– Nucleus
– Cytoplasm
– vacuole
Differences between animal and plant cells
vacuole
Observing living things
• We can see some living thing easily by our eyes.
• Some living things are too small that we need to
use microscope to see them.
• We can use hand lens (magnifier) and binoculars
in observing living things.
