| Three principles of cell theory |
|
Definition
- All living things are composed of one or more cells.
- Cells are the basic units of structure andfunction in an organism.
- Cells come only from the replication of existing cells.

Heart, Veins, and Arteries. Supplies oxygen to our bodies. Arteries carry blood with oxygen to all parts of our body. Veins carry the blood without oxygen back to our heart |

Term
|
Definition
Includes ours mouths (where enzymes begin breaking food down), stomach (contains acid to
break food down), small intestine (where most of our nutrients are absorbed. And large intestine (where
water is absorbed back into our bodies). |
|
|
Term
|
Definition
Where our hormones are produced such as growth hormone and adrenaline (needed for
reacting to stressful situation). |
|
|
Term
|
Definition
Includes our kidneys and urine system and filters waste tobe removed from our bodies.
|

|
Term
|
Definition
| Our skin, the largest organ, protects our other organs, helps us hold water in our bodies, and helps us regulate body temperature through sweating. |
|
|
Term
|
Definition
White blood cells that fight bacteria, viruses and illness for us, are manufactured in
the Lymph nodes throughout our bodies. Lymph enters our bloodstream from the lymph nodes to be
carried throughout our bodies where needed. |
|
|
Term
|
Definition
: Skeletal muscles move our bones, smooth muscles work in our esophagus and intestines, and
cardiac muscles help ourheart beat and pump blood.
|

Definition
Includes the brain, spinal cord, and neurons used for voluntary and involuntary (reflex)
movement. |
|
|
Term
|
Definition
| Used in producing babies and involved in producing eggs and sperm. |
|
|
Term
|
Definition
Includes your lungs and is used to take in oxygen to our blood and get rid of carbon
dioxide. |
|

Term
|
Definition
Adults have 206 bones. They support our bodies, protect our organs, and produce blood cells in
the bone marrow. |
|
|
Term
|
Definition
The neurons from your toes to your head are
long and thin, blood ceils are rounded disks so that they can flow smoothly, and muscle cell are elongated and
flexible. |

Organisms whose cells normally contain a nucleus and make up more complex organisms
|
|
|
Term
|
Definition
| cells that lack a nucleus and have no organelles |
|
|
Term
| Three components of Eukaryotic cells |
|
Definition
cell membrane
nucleus
organelles |
|
|
Term
|
Definition
| protect the cell from its surroundings. |
|
|
Term
|
Definition
| The jelly-like fluid that fills a cell. It is made up of mostly water and salt. Cytoplasm is present within the cell membrane of all cell types and contains all organelles and cell parts. |
|
|
Term
|
Definition
| The cell nucleus acts like the brain of the cell. It helps control eating, movement, and reproduction. |
|
|
Term
|
Definition
| The cell wall gives the plant its actual shape. It acts as a gatekeeper, because it determines what can come in and out of the cell in order to keep the cell protected |
|
|
Term
|
Definition
| As described above, simply contain chlorophyll, a green substance which absorbs light energy for photosynthesis. |
|
|
Term
|
Definition
| holds moisture, and keeps the plant rigid. |
|
|
Term
|
Definition
| bsorbs the light energy needed to make photosynthesis happen |
|
|
Term
| How do plants obtain water? |
|
Definition
|
|
Term
| Where in the plant does carbon dioxide enter the leaves? How do these openings close? |
|
Definition
through openings in the leaves called stoma.
they open in day, close at night
guard cells control closing by losing water
|
|
|
Term
| How does water travel throughout the plant itself? |
|
Definition
water enters the plant primarily through the roots. From there it is carried up through the plant through veins
and into the plant cellswhere it is stored in vacuoles until needed. |
|
|
Term
| In what organelle does photosynthesis take place? |
|
Definition
|
|
Term
| Energy from the sunlight is ultimately stored as what? |
|
Definition
|
|
Term
|
Definition
| Chloroplasts in the leaf traps sunlight/ light energy (plants will grow towards the light energy) |
|
|
Term
| how do we benefit from photosynthesis |

Mitosis Is the method by which eukaryotic cells create Identical copies ofthemselves.
Mitosis allow our bodies and all ofour organ systems to grow larger so we can mature into adults. Mitosis is
also the means by which our bodies repair. |

Definition
1. Prophase - DNA replicated, cell prepares
2. metaphase - DNA condenses, nuclear membrane disappears, chromosomes line up
3. anaphase - chromosomes split.
4. telophase - everythign is divided into two portions
5. cytokinesis - cell actually splits into two |

Term
|
Definition
| Water and minerals absorbed by the roots from the soil, flow up through the stem and enter the leaf |
|
|
Term
|
Definition
| Carbon dioxide enters the leaf |
|
|
Term
|
Definition
| Light energy, water and minerals and carbon dioxide mixed together to make sugar/ food (glucose) for the plant |
|
|
Term
|
Definition
| Sugar (food) leaves the leaf and moves to different parts of the plant |
|
|
Term
|
Definition
| Oxygen leaves the leaf, through the stomata |
