Cells are the basic unit of life. They are ussually microscopic. There are 2 main types: Prokariotyc cells and Eukariotyc cells .

Prokariotyc cells are single-celled organisms. There are 2 types: BACTERIA:Singular: Bacterium. Most common prokariotes. ARCHEA:Singular: Archaeon. Live in places where no other cells live

Eukariotyc cells are VERY large cells. They are the largest cells known! They are about 10 times larger than prokariotyc cells, but they are still microscopic. THEY HAVE MEMBRANE-BOUND ORGANELLES AND A NUCLEUS! 2 types: Animal cels & plant cells

Are Eukariotyc cells An animal cell is a type of eukaryotic cell that lacks a cell wall and has a true, membrane-bound nucleus along with other cellular organelles. Animal cells are smaller than plant cells.

Plant cells are the cells of the plants they are eukariotyc. Even though they are very similar to animal cells they also have some differences⬆️

PLANT CELL STRUCTURE: Nucleus: Is in charge of all cell functions. DNA is stored in it. Membrane: Is a layer that sorrounds the cell and protects it from the outside. Allows food in and release waste substances. Cell wall: holds up the cell. Cytoplasm: Liquid found inside the membrane. Organelles are located on it. Chloroplasts: Organelles in charge of prodicing and storing chemical components escential to the cell. Chloropyll: Give plants their color. Mirochondria: Produce the energy. ANIMAL CELL STRUCTURE: Nucleus: Has the DNA. It "manages" the cell. Membrane: Is a layer that surrounds the cell and protects it. Cytoplasm: Is the liquid substance find inside the membrane. On it we find the organelles. Mitochondria: Is the organelle in charge of producing the energy for the cell. PROKARIOTYC CELL STRUCTURE: The Plasma Membrane:The plasma membrane is a thin layer that completely surrounds the cell and separates the inside from the outside.

First-CELL: Is the basic unit of life. Second-TISSUE: A tissue is a group of cells working together. Third-ORGAN: System of tissues that work together. Fourth-ORGAN SYSTEM: A group of organs working together to perform an especific function. Fifth-ORGANISM: Self-contained organism. THERE ARE DIFFERENT TYPES OF TISSUES AND ORGANS DEPENDING ON WHAT ORGAN SYSTEM THEY CORRESPIND.

Microorganisms are organisms that cannot be seen with the eye. We need a powerful microscope to see them! There are 5 types of microorganisms: FUNGI:  Fungi feed trough hypae. They eat almost everything that was once alive! BACTERIA:  Single-celled organisms. Can be found almost everywhere! VIRUSES:  They can only survive incide the cell of a living organism. When they enter they start to multiply. ALGAE:  Algae are very important microorganisms because they produce much of the earth's oxygen. PROTOZOA:  The word protozoa means little animal, because they search other microbes to eat them. They eat  mostly bacteria and other protozoa.

It´s function is to pass energy from organism to organism. PARTS: Sun: It´s the starting of all. The sun gives energy to the plant. Producers: They produce energy trough a process called photosintesys. They are eaten by other organisms. Consumers:Are animals that eat producers and/or consumers.There are 3 types of consumers: Hervivores: Only  eat producers(plants). Carnivores: Only  eat other organisms. Omnivores: Eat producers(plants) and other organisms. Decomposers: Eat dead organisms AUTOTROPHS AND HETEROTROPHS: Autotrophs: Are also called producers Heterotrophs: Are what we also call consumers. PREDATORS AND PREY: Prey:Is the one that is eaten by the predator. Predators: Eat the prey.

Food webs are very similar to food chains because they perform the same function, to pass the energy from organism to organism.An example⬆️

Humans have positive AND negative impact on the environment. POSITIVE:  Even though humans damage some  plant and that helps the environment. NEGATIVE: One good example of a negative human impact on the environment is population growth. Because we are damaging the environment and we create more humans more humans will damage the environment.

The main goaal of the SDGs is to end problems affecting ALL the world. There are 17 goals⬆️

A biome is a determined part of the globe that share the same climate, flora and fauna. It is clasified by the plants and animals that live there. There are 2 types of Biomes: LAND :   Artic tundra: The artic tundra doesn´t have trees and has a little wildlife. Taiga: Is a  biome full of wild life, bears is an animal veryyyy common there. Temperete forest: Temperate forest are found on cool to warm climates. Has lots of wildlife. Tropical rainforest: It is a very diverse biome it has a GREAT variety of flora and fauna. Grasslands:The grasslands are very large areas of grass and it doesn´t have trees. Savanna: It is very similar to the grasslands but the savanna has trees. Desert: Deserts are hot and dry. There is mostly sand and with very little plant life. AQUATIC: Coral-reef:They are only  in salt water, because salt is essential for them to live. Fresh-water: It is NOT salt water.  Are found in many biomes. PONDS, RIVERS, AND LAKES.

An ecosystem is the interaction of living and non-living things in a certain area. We usually confuse it with a biome but an ecosystem is different from a biome in many ways and similar in other. Some differences between a biome and an ecosystem are that a biome is a geographic are notable for the species living there, while an ecosystem is the interaction of living and non-living things. Also, a biome is a large area, but an ecosystem is a shorter area, usually biomes are made of MANY ecosystems. The ways in wich the biome and an ecosystem are similar is that both give home to animals and plants.

#15-Adaptations Animal adaptatates to it´s environment to survive and hunt. There are 2 forms an animal can adaptate: Behavioral adaptation: Is when an animal does  something to adapt. For example there are animals that act dead so that the predators don´t eat them. Physical adaptation:  When an animal adaptate physically it means that he/she has  something to survive. Some animals camuflate in their environment that is an example of physical adaptation.
