1 ovement = all living things move from place to place

2. Reproduction= organisms making more living things like themselves.
3. Sensitivity = Organisms sense and react to things around them.
4. Growth = living things increase in size.
5. Respiration = Process To release energy for them to use
6. Excretion = Organisms produce waste materials
7. Nutrition = Living things require various substances.
7Ab Organs
ood pipe(gullet) = carries food from your mouth to stomach.
F
Windpipe (trachea) = carries air in and out of your lungs.
Lungs= get oxygen into the blood for respiration and excrete carbon dioxide.
Heart = pumps blood
Diaphragm = helps breathing
Liver = stores some substances, and destroy other substance
Kidneys = Clean the blood and produce urine to excrete wastes.
Large intestine = removes water from unwanted food
Small intestine = breaks up food and absorbs it, to provide nutrition for the body.
Bladder = stores urine
Rectum = stores faeces
, Plant organs
Roots = Absorb water and nutrients from the soil
tem = supports the plant above the ground. It transports water and nutrients from the
S
leaves to other parts of the plant.
eave = Where photosynthesis happens. They capture sunlight and carbon dioxide to
L
produce food (glucose) for the plant.
lowers = Flowers provide nectar to certain birds and insects, which help the transfer of
F
pollen from one flower to the other.
ruits = Fruits develop from flowers and contain seeds. They play a vital role in seed
F
dispersal, as animals often eat fruits and then spread the seeds in different locations.
Seeds = has potential to grow into new plants. It contains an embryo and nutrients.
Photosynthesis = Making food for plants and provide oxygen
1. S
unlight: Leaves capture sunlight through a pigment called chlorophyll.
Chlorophyll gives leaves their green colour.
2. C
arbon Dioxide (CO2): Plants take in carbon dioxide through stomata on the
leaves.
3. Water (H2O): Roots absorb water from the soil and transport it to the leaves.
4. M
aking Glucose: sunlight, chlorophyll in the leaves combines carbon dioxide and
water to create glucose (sugar) and oxygen (O2). This process is represented by
the equation: [6 CO2 + 6 H2O + light energy → C6H12O6(glucose) + 6 O2]
[Carbon dioxide + water + sunlight → glucose + oxygen]*
5. O
xygen: Oxygen is released into the air as a byproduct of photosynthesis, which
is essential for us and other animals.*
6. F
ood for the Plant: The glucose produced during photosynthesis is used by the
plant as an energy source for growth, repair, and reproduction.
, 7. S
tored Energy: Some glucose is stored in roots, stems, and fruits to be used
when needed.*
7Ac Tissue
issue = Each tissue is made up of groups of the same type of cells all doing the same
T
job.
In heart:
Whiter part = fat tissue
- Help to protect the heart
Reddish part = muscle tissue
- To pump blood
lant tissue:
P
Root hair tissue
- Helps the root to take water out of the soil quickly.*
Xylem tissue
- Tissue that carries water in plant. It is found in stem and roots, made of xylem
*cells.
7Ad Cells
Cells = the basic units from which all tissues and all living things are made.
nimal Cells
A
All animal cells have the same basic parts, but cells from different tissues have different
shapes, sizes, and functions to help them do their jobs
Parts of cells
, ytoplasm - Liquid in cells like watery jelly includes respiration which happens in tiny
C
jelly bean-shaped structures called mitochondria.
Parts of plant cells*
Chloroplast - where photosynthesis happen
acuole - storage space filled with cell sap
V
Nucleus - controls the cell*
Cell wall - rigid box that helps support the cell.
hat makes some plant cells green? - Chlorophyll
W
In what part of the cell would you find cellulose? - Cell wall
Part of the cell you can only find in plant cells and not animal cells? - Chloroplast, vacuole, cell
wall*
Ae Organ system
7
Organ system = a group of organs that work together.
Blood vessel = A tube that carries blood around the body
Organ system in human
● Locomotor = that contains all your muscles and bones that allow you to move.
- Muscle, tendon, skeleton.joint
