🗑
|
||||
| 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.
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
