There are so many organisms in this world that some of us don't even know of! This is because these organisms and cells are so small, you have to use a microscope to see them! I have provided some words and definitions so you can take a journey into the world of the unseen, at least unseen without a microscope. Enjoy!
A
Algae- Eukaryotic organisms that convert the sun’s energy into food through photosynthesis but that do not have roots, stems, or leaves Amoebas- Amoebas and similar amoeba-like protists are soft, jellylike protozoans. They are found in both fresh and salt waters, in soil, and parasites in animals. Asexual Reproduction- A type of reproduction where the offspring comes from one parent, the offspring and parent are identical B Brown Algae- Most of the seaweeds found in cool climates. Attach to rocks or form large floating beds in ocean waters. Binary Fission- A type of reproduction where a single-celled protest divides into two cells C Chloroplasts- Structures in cells that capture energy from the sun Conjugation- A way of reproduction where two individuals join together and exchange genetic material. Colonies- Groups where individual cells of some species of green algae live Ciliates- Complex protists that have hundreds of tiny, hair like structures known as cilia Cilia- Tiny, hair like structures that can move a protist forward by beating back and forth. Contractile Vacuole- Pumps out excess water in a paramecium D Decomposers- A protist heterotrophs that get energy by breaking down dead organic matter Diatoms- Single-celled organisms that are found in both salt and fresh water, and get their energy from photosynthesis Dinoflagellates- Single-celled organisms that live in salt water, but some live in fresh water. Some even live in snow. They have two whip like strands called flagella. E Eukaryotic- Types of cells that have a nucleus Euglenoids- Single-celled protists that mainly live in fresh water Eyespots- Parts of the euglenoids that help euglenoids sense light since they cant see F Food Vacuole- A place where enzymes move into the vacuole to digest food, and the digested food passes into the vacuole Flagella- Two whip like strands that beat to help cells spin through the water Foraminiferans- Amoeba-like protists that have snail-like shells which move by poking pseudopodia out of pores in the shells Fungi- Eukaroytic heterotrophs that have rigid cell walls and no chlorophyll G Green Algae- The most diverse type of protist producers that are green because chlorophyll is the main pigment in their cells Giardia Lamblia- A parasite that can live in the digestive tract of many vertebrates Gill Fungi- The most familiar type of mushroom H Heterotrophs- Organisms that cannot make their own food so they eat other organisms, parts or products of other organisms, or the remains of other organisms Host- An organism from which a parasite takes food or shelter Hypha- a nonreproductive filament of a fungus L Lichen- A combination of fungus and an alga that grows together M Multiple Fission- When single-celled protists make more than two offspring from one parent, each cell is a single-celled protists Mutualism- An organism that lives closely with another organism and helps the other to live Macronucleus- A large nucleus in a paramecium that controls the functions of the cell Mycelium- the mass of fungal filaments, or hyphae, that forms the body of a fungus Micronucleus- The smaller nucleus of the paramecium that passes genes to another paramecium during sexual reproduction Mycorrhiza- A relationship between a plant and a fungus where the fungus helps the root absorb minerals and protects the plant from some disease-causing organisms P Protist- a member of the kingdom Protista that differ from other living things in many different ways. Pretzel Slime Mold- A form (type of shape) of a protist Paramecium- A form (type of shape) of a protist, the best known genus of ciliates. Producers- Types of protists that make up their own food which have special structures called chloroplasts Photosynthesis- A process in which protists use sun energy to produce food Parasite- An organism that feeds on an organism of another species (the host) and that eventually harms the host; the host never benefits from the presence of the parasite Parasitic Protists- Protists that invade fungi, plants, or animals. In the mid-1800s wiped out most of Ireland’s potatoes, leading to starvation Plasmodium Vivax- The protist that causes the disease Malaria, P. Vivax depends on both humans and mosquitos to reproduce Phytoplankton- Free-floating single-celled algae that can’t be seen without a microscope Protozoans- Protists that can move and are usually single-celled consumers or parasites Pseudopodia- the parts of amoebas and amoeba-like protists that help them move by stretching out a pseudopod from the cell Penicillium- The source of antibiotic penicillin R Red Algae- The majority of the types of seaweed that live in tropical oceans attached to rocks or other algae, and are less than 1 meter in length Radiolarian- Amoeba-like protists that have shells S Sea Weeds- Many celled algae that generally live in shallow water along the shore Silica- A glass like substance that are contained in cell walls of diatoms U Ulva- A form (type of shape) of a protist V Volvox- A green alga that grows in round colonies Z Zooflagellate- Protists that wave flagella back and forth to move and live in water or the bodies of other organisms |
