Animal tissues PHOTO ALBUM.

In unicellular (single-celled) organisms, the single cell performs all life functions. It functions independently.

However, multicellular (many celled) organisms have various levels of organization within them. Individual cells may perform specific functions and also work together for the good of the entire organism. The cells become dependent on one another.

Multicellular organisms may have the following 5 levels of organization ranging from simplest to most complex:

Cells --> tissues --> organs --> systems --> organism.

Some multicellular organisms do not have tissues (fungi kigndom, some algae in protoctist kingdom). Others have all levels of organization (birds class in animal kingdom).

The following album, shows different tissues humans have, each one carries out a specific function.




LEVEL 1 - Cells
Are the basic unit of structure and function in living things.
May serve a specific function within the organism
Examples- blood cells, nerve cells, bone cells, etc.

LEVEL 2 - Tissues
Made up of cells that are similar in structure and function and which work together to perform a specific activity
Examples - blood, nervous, bone, etc. Humans have 4 basic tissues: connective, epithelial, muscle, and nerve.

LEVEL 3 - Organs
Made up of tissues that work together to perform a specific activity
Examples - heart, brain, skin, etc.

LEVEL4 - Organ Systems
Groups of two or more tissues that work together to perform a specific function for the organism.
Examples - circulatory system, nervous system, skeletal system, etc.
The Human body has 11 organ systems - circulatory, digestive, endocrine, excretory (urinary), immune(lymphatic), integumentary, muscular, nervous, reproductive, respiratory, and skeletal.

LEVEL 5 - Organisms
Entire living things that can carry out all basic life processes. Meaning they can take in materials, release energy from food, release wastes, grow, respond to the environment, and reproduce.
Usually made up of organ systems, but an organism may be made up of only one cell such as bacteria or protist.
Examples - bacteria, amoeba, mushroom, sunflower, human

ÁLBUM DE FOTOS de tejidos animales.

En organismos unicelulares, la propia célula lleva a cabo todas las funciones vitales. Es funcionalmente independiente.

Sin embargo, los organismos pluricelulares presentan varios niveles de organización. Las células realizan funciones específicas y también trabajan juntas para beneficio del organismo completo. Las células son dependientes unas de otras.

Los organismos pluricelulares pueden tener los siguientes niveles de organización, enumerados desde el más simple, al más complejo.

Células --> tejidos --> órganos --> aparatos/ sistemas --> organismo.

Algunos organismos pluricelulares no tienen tejidos (Reino Hongos, algas del Reino Protoctista). Otros tienen todos los niveles de organización (la Clase Aves en el Reino Animal).

En el siguiente álbum se muestran distintos tejidos humanos, cada uno realiza una función específica

Sexual reproduction in the Animal Kingdom.

To survive and reproduce, all living organisms must adjust to conditions imposed on them by their environments. An organism's environment includes everything impinging upon it, as well as everything that is affected by that organism. Conformity between an organism and its environment constitutes what biologists call adaptation.

TASK 1
You have been asked to investigate the unusual reproductive habits of Emperor penguins. Find out about the difficult conditions in which they reproduce. Include the following:
• Describe their habitat conditions.
• Is this external, or internal fertilization? Why do you thing they carry out this type of fertilization?
• When do Emperor penguins reproduce?
• Do they make nests? Why?
• Who has the easier job, the male or the female?

TASK 2
Imagine you are a fish. One of your best friends is a male anglerfish. He has just met the female anglerfish of his dreams. Tell him what to expect on his honeymoon. Explain what is so unusual about reproduction in anglerfish.

• Describe their habitat conditions.
• Is this sexual, or asexual reproduction?
• Why do you thing they carry out this type of reproduction?
