Term | Definition |
Amoebae | single-celled life-form characterized by an irregular shape and move using pseudopodia, or temporary projections of eukaryotes. |
Autotrophs | organisms that make their own food. |
Cilium | "hair-like" structures that outer membrane of some cells specialized for locomotion or movement. |
Cytoplasm | Cytoplasm is a gel-like substance residing cell membrane holding all the cell's organelles, except for the nuclues. |
Cytoplasmic Streaming | streaming is the directed flow of cytosol or the liquid component of the cytoplasm around plant cells. |
Euglena | a protist that can both eat food as animals by heterotrophy; and can photosynthesize, like plants, by autotrophy. |
Eukaryotes | cellular organisms that cannot make their own food. |
Flagellum | "tail-like" structure attached to the outer membrane of some cells specialized for locomotion or movement. |
Heterotroph | are organisms that cannot make their own food. |
Multicellular | organisms are composed of many cells. |
Paramecium | a group of unicellular protozoa, which are commoly studied as a representatice of the ciliate group, or cilia movement. |
Phagocytosis | the cellular process of engulfing solid particles by reshaping the cell membrane. |
Prokayotes | cellular organisms that lack a nucleus. |
Protists | eukaryotes that cannot be classified as animals, plants, or fungi. |
Protozoa | a diverse group of single-cell eukaryotic organisms, many of which are motile. |
Unicellular | organisms are single-celled. |
Volvox | a type of green algae and forms spherical colonies of up to 50,000 cells who live in a variety of freshwater habitats. |
Active Tansport | Use energy to "carry" substances into a cell. One method of active transport is to pick up the substance outside the cell and pull it through the cell membrane. |
Cell | Basic unit of structure and function in living things. It is the basic building block of life. |
Cell Membranne | Found in plant and animal cells
A double lipid layer that has proteins in it
Functions:protection, support, movement of substances in and out of the cell(osmosis, diffusion, active transport) |
Cell wall | It gives protection and support
It is found in plant cells
It is not found in animal cells |
Chloroplast | Found in plant cells only |
Rough Endoplasmic Reticulum | Found in plant and animal cells. A maze of tubular passageways throughout the cell. The transportation system for the cell-helps to move substances through the cytoplasm of the cell.The R.E.R has ribosomes attached to its surface. |
Smooth Endoplasmic Reticulum | Found in plant and animal cells.A maze of tubulat passageways throughout the cell. The transportation system for the cell-helps to move substances through the cytoplasm of the cell. The S.E.R does not have ribosomes. |
Vacuoles | Found in plant and animal cells- BUT there is only one large vacuole in plant cells, and animal cells have few little ones. These are the storage tanks for the cell- they store water, food, waste enzymes, etc. |
Cells | the basic unit of structure and function in living things. |
Hieratchical | the arrangement of a particular set of items that are represented as being "above", "below", or "at the same level as" one another. |
Organ System | 2 or more organs working together in the execution of a specific body function. |
Organelles | A structure within a cell that carries out the various processes necessary for a cell to function properly. |
Organism | A life form such as animal, fungus, micro-organism, or plant that in some form is capable of response to stimuli, reproduction, frowth, development and maintenence of homoeostasis. |
Organs | A collection of tissues joined into a structural unit that serves a common function. |
Specialized | Ais a type of cell that performs a specific function in multicellular organisms. Groups of specialized cells work together to form a tissue. |
Tissue | A tissue is a group of cells from the same origin that together carry out a specific function. |
Alleles | The different forms of a gene |
Asexual Reproduction | A form of reproduction in which new organism is created from a single parent and inherits the genes of that parent only. |
Binary Fission | A subdivision of a cell into two or more parts and the regeneration of those parts into two separate cells. |
Budding | Asexual reproduction is when a new organism grows on another.The new organism remains attached as it grows,separating from the parent organism when it is mature.The newly created organism is a clone and is genetically identical to the the parent organism. |
Dominant Allele | A form of a gene, whose trait always shows up in an organism when the allele is present and working correctly. |
Egg cell | The "female" sex cell; contains 1/2 the genetic information of the female parent. |
Fertilization | The process in which the sex cells of different organisms of the same species combine to produce a new organism. |
