Viruses


A virus is nonliving structure that attacks cells and multiplies by injecting RNA or DNA telling the cell to make multiple copies of the virus. Viruses such as Rhinoviruses give you colds.

Bacteria


Bacteria are small single celled organisms that have a cell wall and do not have a well, defined nucleus.

Archea


Archea are small single celled organisms that have a cell wall and do not have a well, defined nucleus, just like the bacteria. Archea tend to be extremophiles. Extremophiles can live in extreme conditions such as high and low temperatures.

Animal Cells

Organelles and Their Functions


Cell:

The smallest unit that can performs all life procesess

Cell Membrane:

The outside of an animal cell, contains proteins, lipids, and phospholipids

Cytoskeleton:

The cytoskeleton is a mesh of different proteins in cells.

Nucleus:

Contains all cell DNA

Ribosomes:

The producer of proteins

Endoplasmic Reticulum:

The internal delivery system of a cell. Also produces proteins, lipids, and other materials.

Mitochondrion:

Main energy source of a cell. It gets it's energy by breaking down sugar through ATP

Golgi Complex:

Packaging system of the cell

Vesicle:

A small sac containing fluid or gas.

Lysosomes:

Vesicles that are responsible for the digestive system. Also destroy worn-out or dammaged organelles.

Plant Cell

Organelles and Their Function

Cell Wall:

Provides protection from physical injury.

Chloroplast:

Chloroplast are the food producers of the cell. They are only found in plant cells.

Large Central Vacuole:

The large central vacuole stores salts, minerals, nutrients, proteins, pigments, helps in plant growth, and plays an important structural role for the plant.

Photosynthesis:

Photosynthesis is a process in which green plants use energy from the sun to transform water, carbon dioxide, and minerals into oxygen and organic compounds.

Meiosis

Makes sex cells. Makes 4 daughter cells.

Mitosis

Makes 2 daughter cells

Plant Parts

Petals:

Attracts insects and other pollinators

Stem:

Carries water and minerals up from the roots to the leaves to help with photosynthesis

Roots:

An underground organ that sucks up water and nutrients for the plant

Pistil:

Pollen travels through here

Stigma:

Traps pollen

Ovary:

Contain egg cells

Stamen:

Provides support for Anther

Anther:

Makes pollen

Sepal:

Protects flower bud

Photosynthesis

CO2 + 2H2O + sunlight ---> O 2 + (C H2O)n + H2 O
When this formula is successful glucose is made and provides foods and nutrients for the plants.





















Favorite Non-Fantasy Organism

I think Ligers are cool because they are a mix between a tiger and a lion, and that is just too cool. They are also really, really, really big
