Five kindoms
Living
things are classified into five groups called kingdoms. Theorganisms belonging
to the same kingdom share a number ofand are different from other organisms
from different kingdoms.
Plant kingdom: They are multicellular, manufacture their own food, they absorb
dioxide carbon dioxide and expel oxygen. This kingdom is consisting of plants,
within which are mosses, ferns, grasses,shrubs and trees. They can move but not
fixed scroll and living in the soil.
Kingdom Protist: It consists ofprotozoa and algae. They can be
unicellular or multicellular.The algae make their own food and most live in the
water, while the protozoa feed on other beingsalive and some are parasites.
They are unicellular. They live in aquatic environments andwithin other living
beings.
Kingdom Monera: All are unicellular, they can be foundwater,
soil or air, such as bacteria, some. They produce their own food and some not.
Together withFungi play an important role, which is the decomposition.
Kingdom Animal:are multicellular organisms.They
live in all types of environments: land, Water, Air Ground. The animal kingdom divided
into two main groups: vertebrates and invertebrates. They are multicellular. They
feed on other living beings and can move.
Kingdom Mushroom: The kingdom is consisting of
fungi. They feed other living beings. They may be multicellular like mushrooms
or mushrooms. but may also beas unicellular yeasts. Together with bacteria,
fungi recycling of material carried through the decomposition process.
Animal and plant cell
- A thin
membrane surrounding the cell, protects and allows the passage ofCertain
substances, called Plasma Membrane.
-
The cytoplasm is a gelatinous substance which reactions occurchemicals
-
The core containing the information to regulate cell functions and where the
hereditary genetic material. Inside you found chromosomes. Controls the
functions of the cell.
- The
vacuoles contain water and minerals that the body needs to grow.
-Plant
cells also have a cell wall composed ofcellulose, that surrounds and provides
the characteristic consistency the vegetables. These cells also possess
chloroplasts, organelles with asubstance called chlorophyll. Chloroplasts are
responsible for performing photosynthesis.
-Some are
single-celled organisms like paramecium, others are multicellular, like birds
Three vital
functions
Vital functions are processes that all living beings made tostaying alive. Vital functions are three
• Nutrition.
• Interaction.
• Reproduction.

• Nutrition.
• Interaction.
• Reproduction.
NUTRITION
They take nutrients from the environment to transform them intoenergy, to live, grow and develop. There are different processes:
• Plants make their own food (photosynthesis).
• The animals eat other living things.
• The decomposers (fungi and bacteria)
They feed on the remains of living things.

INTERACTION
All living things interact withthe environment, is called stimulus, whichIt produces a reaction. Animals use sense for it and plants, but notThey have them also react.

REPRODUCTION
Living things produce similar bodies to them, the reproductioncanbe sexual or asexual.
Living things produce similar bodies to them, the reproductioncanbe sexual or asexual.
Asexual: Only one body is
required,such as bacteria.
Sexual: two agencies are needed,male and female

Specialised cells
Plant cell
Root hair cell: They absorb water and minerals
Leaf cells: They collect suniight for photosynthesis
Animal cell
Red
blood cells: They carry
oxygen .
White
blood cells: They
protect the body from bacteria, viruses and other foreign invaders.
Nerve
cells: They carry nerve
impulses from our brain to the rest of the body and also from our brain.
