UNIT 1LIVING THINGS
CHARACTERISTICS OF LIVING THINGS
All living things....
- ... need food to obtain energy. NUTRITION
- ... exchange gases (oxygen and carbon dioxide) with the environment. RESPIRATION
- ... produce waste. EXCRETION
- ... use energy from food to grow. GROWTH
- ...can move. Plants can only move some parts but many animals can jump, walk, run, fly, etc. MOVEMENT
- ...interact with the world around them. Most living things react to light, temperature and sound. INTERACTION
- ...produce offprings, that is, they have babies. REPRODUCTION
the life processes of living things
nutrition
interaction
reproduction
All living things take nutrients from food and change them into energy. They need energy to grow.
All living things interact with their environment. A change in the environment is a stimulus and the reaction is a response.For example, listening to music is a stimuli and dance is a response. Animals use their sense organs to detect stimuli.
This process allow living things to create new living things similar to them. Reproduction is essential for the continuation of the species.They reprduce in different ways: -Mammals are viviparous -Birds, reptiles, amphibians and fish lay eggs so they are oviparous. -Some bacteria divide to make copies of themselves. -Plants can have sexual or asexual reproduction.
Plants are producers, they make their own food (glucose) through a process called photosynthesis. Animals are consumers, they must feed on other living things.. Fungi and bacteria are decomposers, they feed on the remains of dead plants and animals.
cells
All living things are made up of very small units called cells.We need a microscope to see cells because they are very small.Depending on the number of cells there are: -Unicellular organisms: they have got only one cell such as bacteria and yeast. -Multicellular organisms: they are made up of many cells such us trees and butterflies. Because cells are living things they perform the three life processes: nutrition, reproduction and interaction. They take in nutrients and they reproduce by dividing into two again and again.

PARTS OF A CELL
Cells have many parts, called organelles. Some examples of organelles include the nucleus, the cytoplasm, the cell membrane, the vacuole, and the mitochondria. Each organelle has a specific function to help keep the cell alive.

- Plants cell have a rigid wall around the menbrane.This helps support the plant.
- Chloroplast contain a green substance called chrorophyll-

HOW ARE LIVING THINGS ORGANISED?
Cell Tissue Organ System Organism
A group of cells that work together in a coordinated way to perform a task form a tissue.
A set of tissues that work together. It keeps the organism alive.
A group of organs that work together to perform a different function.
It is the smallest unit
When all the systems work together, they form an organism. An organism is a living thing.
CLASSIFICATION of living things
Living things are classified into five groups called kingdoms.
The Protist Kingdom
The Monera Kingdom
The Fungus Kingdom
They are unicellular and can be found on land, in the air, in water and inside other living things. Bacteria belong to this group. Bacteria can be harmful or helpful. Some bacteria can cause illness while other are used to make food such as cheese or yoghurt.
They can be either unicellular such as yeast or multicellular such as mushrooms. Fungi can't make their own food so they take the nutrients they need from remains of dead plants and animals.
Most protist can be found in water. The amoeba is unicellular, which takes in its food by absorbing it. Algae is a protist that can be unicellular or multicellular.
The Plant Kingdom
The Animal Kingdom
All plants are multicellular. They make their own food through a process called photosynthesis. During this process plants release oxygen. Plants can't move around but they can react to stimuli such as light and water. We can classify plants into flowering and non-flowering plants.
They are multicellular and feed on other living things. Animals release carbon dioxide into the air through the process of respiration. They are classified into two groups: vertebrates and invertebrates.
