Question | Answer |
---|---|
four differences between animal and plant cells | 1) animal cell is round and plant cell is rectangular 2) animal cell has many small vacuoles and plant has one big one 3) plants have a cell wall and animal cells don't 4) plants have chloroplasts and animals cells don't |
What are the three parts of the CELL THEORY? | 1) all living things are made of cells 2) cells are the smallest unit of structure and function 3) cells come from other living cells |
organism | any living thing |
unicellular | one cell |
multicellular | many cells |
organelles | cell parts |
cellular respiration | the process that changes food energy into energy that cells can use. Happens in the MITOCHONDRIA |
CELL MEMBRANE | A protective covering that surrounds, protects and controls what goes in and out. |
CYTOPLASM | A jelly like substance that fills the cell and holds the organelles. |
NUCLEUS | the control center or "the brain of the cell" |
CHROMOSOMES | contains the blueprints or DNA for the cell |
VACUOLES | Storage tanks filled with water, food, and waste |
E.R. (endoplasmic reticulem) | transports materials (proteins) |
RIBOSOMES | this is where the proteins are made and is also attached to the ER's wall |
MITOCHONDRIA | the powerhouse of the cell that breaks down food to release energy |
CHLOROPLASTS | structures that contain a green pigment called chlorophyll and where the plant makes food |
CELL WALL | surround, protects, and provides structure to plants |
Ingestion | the taking in of food |
Examples of ingestion in animals and plants | animals: a mosquito sucking blood out of a dog plants: plants absorb water and other minerals through their roots |
digestion | breaking down food into usable forms |
Examples of digestion in animals and plants | animals: a rabbit chews a carrot to give it energy plant: plants use sugars |
Circulation | transporting materials within the organism |
Examples of circulation in animals and plants | animals: horse's heart pumps blood for it plants: three roots and veins move water through a plant |
Respiration | the release of energy by combining oxygen with digested food |
Examples of respiration in animals and plants | animals: a fish moves its gills to take in oxygen so its cells can make energy plants: take in CO2 through the leaves |
Excretion | removing waste products |
Examples of excretion in animals and plants? | animals: a cat pees in a litter box plants: gives off water vapor |
Response to stimuli | reacting to something new in an environment |
Examples of animals and plants responding to stimuli. | animals: a resting dog suddenly points its ears plants: plants grow toward light |
Movement | going from one place to another |
Examples of how animals and plants move | animals: dog runs to fetch a ball plants: some leaves close up at night |
Reproduction | making more of one's own kind |
Examples of reproduction in animals and plants | animals: a cat gives birth to kittens plant: plants make seeds |
Growth | getting larger and/or changing form |
Examples of growth in animals and plants | animals: a puppy becomes a dog plants: a plant needs a bigger pot for its roots |
