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
  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.

 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.
