Cells are the basic units of life that make up all living things. They carry out three basic life processes: nutrition, reproduction, and sensitivity. Cells contain organelles that carry out different functions - the membrane controls what enters and exits, the nucleus controls the cell, and the cytoplasm contains organelles and carries out their functions. Cells are organized into levels with cells forming tissues, tissues forming organs, and organs forming systems. There are different types of tissues including blood, muscle, bone, nervous, fat, and epithelial tissues that have specific functions like movement, support, information transport, storage, and protection.

4. Cells are the BASIC UNITS OF LIFE.
All living things are made up of CELLS.

5. THE THREE BASIC LIFE PROCESS
NUTRITION REPRODUCTION SENSITIVITY

6. NUTRITION. Cells obtain nutrients and energy from food.
REPRODUCTION. Cells divide and produce new cells that are
identical to themselves.
SENSITIVITY. Cells react to what they perceive around them.

8. Organelles
MEMBRANE: Control what enters and leaves
the cell. It‘s the covering around the cell.
NUCLEUS: It controls the cell.
CYTOPLASM: It’s the liquid inside the cell. It
contains the organelles, which carry out
different functions of the cell.

9. Organelles

11. Cells in multicellular living things are organised in levels – LEVELS OF
ORGANIZATION.

12. Cells are
specialised: they
have specific
functions.
Cells form tissues.
Tissues are groups
of cells with the
same function.
Tissues form organs.
Organs are groups
of various tissues
which act together.
Organs form systems.
Systems are made up of
several organs

15. BLOOD TISSUE – (it’s made
up of blood cells). It carries
SUBSTANCES throughout the
body.
MUSCLE TISSUE – (it’s
made up of muscle cells). It
is responsible for
MOVEMENT.
BONE TISSUE – (it’s made up
of bone cells). It forms bones
and supports the body.
NERVOUS TISSUE – (it’s
made up of NEURONS). It
carries INFORMATION to the
BRAIN.
FAT TISSUE – (it’s made up of
FAT cells). It is specialized in
STORING FAT.
EPITHELIAL TISSUE – (it’s
made up of epithelial cells). It
forms the skin and provides
protection to the body.

16. DERMAL TISSUE covers the leaves and
provides protection.
GROUND TISSUE provides support, stores
nutrients and performs photosynthesis.
VASCULAR TISSUE is found in the xylem
and phloem vessels. It transports
substances.
