Cells & Bacteria DUT
WKMS Ms. P - Cells & Bacteria
Question | Answer |
---|---|
cell membrane | cell organelle that controls what enters and leaves a cell. |
diffusion | process by which materials, including wastes, move across the cell membrane from an area of higher concentration to an area of lower concentration. |
osmosis | the diffusion of water across a membrane. |
Cytoplasm | gel-like fluid inside of a cell in which the other organelles are embedded. |
Nucleus | cell organelle in which mitosis occurs and is the control center of the cell. |
Vacuole | cell organelle where excess glucose is stored after photosynthesis. |
Chloroplasts | cell organelle in which photosynthesis takes place in plants. |
Mitochondria | cell organelle in which respiration takes place releasing energy. |
Cell wall | plant cell organelle that is made mostly of cellulose and provides support and shape for the cell. |
Structures that are specific to plants | the cell wall and chloroplasts |
Bacteria | single celled organisms that are classified into the Moneran Kingdom. |
Spiral | corkscrew shaped bacteria |
Bacillus | Rod-shaped bacteria |
Coccus | Round-shaped bacteria |
Protists | typically single celled organisms that live in moist environments and are classified by the way they obtain food and move. |
Euglena | protists that possess characteristics of both plants and animals and move by pulling themselves with long whip like structures called flagella. |
Paramecium | protists that capture food and move by beating tiny hair-like structures called cilia. |
Amoeba | protists that use pseudopods to trap food and pull themselves through their environment. |
Photosynthesis | cell process by which plants use light energy to combine carbon dioxide (CO2) and water (H2O) to make simple sugars (C6H12O6) and release oxygen gas (O2). |
Respiration | cell process by which all organisms break down simple sugars (C6H12O6) into carbon dioxide (CO2) and water (H2O) and release energy. |
Waste elimination | cell process by which organisms rid the cells of waste products that could be harmful to the cell. |
Mitosis | process of cell division that is needed for growth, replacement, and asexual reproduction. |
raw materials of photosynthesis | carbon dioxide and water |
products of photosynthesis | glucose and oxygen |
raw materials of respiration | glucose and oxygen |
products of respiration | carbon dioxide and water (energy is released) |
photosynthesis & respiration are | opposite processes |
