Plants

0. Introduction.
Look at the diagram about plants. Think of the missing words. Then, in your notebook, write complete sentences using the information available. 


1. Parts of a plant.
Most plants have three parts: the roots, the stem and the leaves. 


2. Classification of plants.


3. Plant nutrition. 

A. Photosynthesis: 
Photosynthesis is the process by which green plants make their own food.


* - Raw sap: savia bruta.
   - Elaborated sap: savia elaborada.
   - Xylem vessels: vasos leñosos o xilema.
   - Phloem vessels: vasos liberianos o floema.
   - Stomas: estomas.

B. Respiration

C. Nutrition and respiration in the day and at night. 


4. Sexual reproduction in plants.

A. Reproduction in flowering plants.

It takes place inside the flower. Flowers are the reproductive organs in most plants and have male and female reproductive organs.

Wind, insects and other agents can accidentally transport pollen from one flower to another.
There are two types of pollination:
- Self-pollination (auto-polinización).
- Cross-pollination (polinización cruzada).

B. Reproduction in non-flowering plants:
Non-flowering plants don´t have flowers or seeds. So, they use spores to reproduce. Ferns reproduce this way.

5. Axesual reproduction in plants.
Many plants that grow flowers and seeds can also reproduce through fragmentation. In fragmentation, a new plant grows from a fragment of the parent plant.

There are different types of fragments in asexual reproduction:
- Stolons (estolón).
- Tubers (tubérculos).
- Bulbs (bulbos).
- Rhizomes (rizomas).
- Cuttings.

Unit 2: The variety of life (5º EP)

1. INTRODUCTION:

Scientists have identified nearly two million of Earth´s species, but they believe there are actually many more. To classify all living things we study their cellular structure and their nutrition. According to this, living things can be classified into five groups called kingdoms. 
Organisms of the same kingdom share similarities and are different from organisms in other kingdoms.

1. THE PLANT KINGDOM
2. THE ANIMAL KINGDOM
3. THE FUNGI KINGDOM
4. THE PROTIST KINGDOM
5. THE MONERA KINGDOM



2. THE 5 KINGDOMS:


1. ANIMAL KINGDOM

- Animals are multicellular.
- They can´t make their own food, so they get the energy they need to survive by feeding on other living things (heterotrophic).
- Their cells have nucleus (eukaryotic).
- Most animals have the ability to move.
- Type of organism: All animals, including you!



2. PLANT KINGDOM

- Plants are multicellular.
- They make their own food (autotrophicthrough a process called photosythesis. During     photosynthesis plants absorb carbon dioxide and release oxygen.
- Their cells have nucleus (eukaryotic).
- They can´t move.
Type of organism: All plants, except for the simplest single-celled algae.




3. FUNGI KINGDOM

- Fungi can be unicellular or multicellular.
- Fungi can´t make their own food, but they obtain the nutrients they need from the remains of dead plants and animals (heterotrophic).
- Their cells have nucleus (eukaryotic).
- Like plants, they can´t move.
- Fugi can be very useful - penicillin is made from moulds, yeast is used in baking and brewing, and we can eat mushrooms.
- Type of organism: Fungi including mushrooms, toadstools and yeasts.



4. PROTIST KINGDOM (Algae and protozoa)

- Protists are usually unicellular, but some are multicellular.
- Their cells have nucleus (eukaryotic).
- Most protists are found in water.
Type of organism: Protists including single celled algae, slime moulds and amoeba.



a. Algae:
- Algae can be unicellular and multicellular.
- They make their own food but have different parts to plants (autotrophic).

b. Protozoa:
- Protozoa are unicellular.
- Feed on other living things (heterotrophic).

5. MONERA KINGDOM

- All organisms in this kingdom are unicellular and are so small.
- They are the simplest organisms on Earth.
- Bacteria belong to this kingdom.
- Some bacteria produce their own food (autotrophic) and other feed on other living things (heterotrophic).
- Their cells have no defined nucleus.
- They can be found everywhere (on land, in the air, in water and inside other things.
- We use some bacteria to make food, such us cheese and yoghurt.

3. FROM INDIVIDUAL TO COMMUNITY.


Organisms in the same area form groups. Those that belong to the same species are called a population. Populations interact with each other and form a community. Populations interact not only with their physical environment.

*An ecosystem includes all the living and non-living things (physical environment) in a specific area and the interaction that occurs between them.

*The biosphere is the global ecosystem which contains all other ecosystems.

3. RELATIONSHIPS BETWEEN LIVING THINGS.

There are different types of relationships between organisms. The relationships between living things can be intraspecific and interspecific.

A. INTRASPECIFIC RELATIONSHIPS

- Reproduction: Living things of the same species interact and breed to produce more members of the same species.
- Protection: Some species of animals live in herds to protect themselves from predator attacks.
- Feeding: Some species hunt in packs in order to catch and kill larger animals for food.
- Competition: Living things of the same species compete for resources in an area (food, water, space, light...)

B. INTERSPECIFIC RELATIONSHIPS

- Predation (+, -): It is a relationship in which one organism kills and eats another. Lions (predators) eat zebras (prey).

- Competition: Living things of the different species compete for resources in an area (food, water, space, light...) .

- Symbiosis: Close relationship between two species that benefits at least one of the species. There are three types:

1. Parasitism (+, -): It is a relationship that benefits one organism (the parasite), and can harm the other organims (the host). Some common parasites are fleas, leeches, ticks and tapeworms.

2. Commensalism (+, 0): It is a relationship that benefits one organism and does not help or harm the other organism. For example: A nest and a tree, a remora fish a a shark,...

3. Mutualism (+, +): It is a relationship where both species benefit. For example, bees and flowers.

The Universe and the Earth


The Universe includes planets, stars, solar systems and galaxies. No one knows exactly how big the Universe is.

Our Solar System is made up of all the celestial bodies that orbit the Sun. It is in the galaxy called the Milky Way.

5.1. LIVING THINGS

UNIT 1: LIVING THINGS

1. INTRODUCTION

Life on Earth first appeared approximately 3.8 billion years ago. The first living things were single cells similar to bacteria. It was only much later, around 570 million years ago, when more complex organisms started to appear. Since then, life forms can be found almost everywhere on Earth, but what about in the rest of the Universe? Do you know if there is life on other planets?




ACTIVITY:
a)    Do you think these things are living or non-living? Complete the table.

-         mould                          - moss                                              - water
-         stone                           - apple tree                                       - spider

Living things
Non-living things





     b)  What differences can you find between the two columns?


     2.     THE CHARACTERISTICS OF LIVING THINGS

     A)    VITAL FUNCTIONS

In spite of their differences, all living things perform three vital functions in order to live and grow: NUTRITION, REPRODUCTION AND INTERACTION.


a)      NUTRITION
Living things need energy in order to carry out their life functions. Energy comes from nutrients (food). Nutrients help them to grow and function properly.

Animals 
Animals do not make their own food. Some eat meat (carnivores), some eat plants (herbivores) and some eat meat and plants (omnivores).

Plants
Plants use sunlight, water, carbon dioxide and minerals to make their own food (photosynthesis).

b)      REPRODUCTION
Living things reproduce. Reproduction means they can make other living things.
Animals
Some animals are born live (viviparous) and others are born from eggs (oviparous).
Plants
Most plants reproduce by seeds, spores or a piece of the same plant.





c)       INTERACTION
Living things interact with the world around them. Moving, touching and communicating are examples of interaction.

Animals
Animals can move, communicate, hunt and react to the world around them.
Some animals live in group and some animals live alone.

Plants
Plants also react to the environment. They grow towards the light and their roots grow towards water. Some plants open and close, and some plants can climb.

4. THE CELL

All living things are made up of tiny units called cells and perform the three vital functions: nutrition, interaction and reproduction. A cell is the smallest unit of life.

CELL STRUCTURE

Plant and animal cells have the following parts:

5. Multicellular and unicellular organisms



6. Multicellular organisms

Multicellular organisms are living things that are composed of two or more cells. For example humans.
In multicellular organisms, cells are grouped to form different levels of organization. The end result is an organism.
