| What are the four different types of plant tissue and their functions and locations? (Ch. 29) |
|
Definition
Meristematic Tissue - Responsible for plant growth, primary and secondary. Continual growth and production of new cells by mitosis.
Epidermal Tissue - forms the outside layer of roots, stems, and leaves, and is typically made of parenchyma cells.
Ground Tissue - (mesophyll) is surrounded by epidermal tissue and primarily composed of parenchyma cells that occupy the area between the vascular tissue and epidermis. This is where photosynthesis, metabolism, and storage occur.
Vascular Tissue - xylem and phloem, consist of cells joined together to form tubes and pipes that provide a path for water and food to the plant. |

| The above-ground parts of a vascular plant. |
|
|
Term
|
Definition
| The underground anchor for a plant. Roots also serve as a major point of entry for water and minerals. |
|
|
Term
| Secondary Growth (Ch. 29) |
|
Definition
| An increase in stem and root diameter made possible by mitotic cell division of the lateral meristems. |

Term
|
Definition
| The pollen-producing portion of the plant. This is a sporophyte structure where microspores produced by meiosis develop into male gametophytes. |
|
|
Term
|
Definition
| The basal, swollen portion of the plant that contains the ovules and develops into the fruit. |
|

|
Definition
| Contains the pollen-bearing anther. |
|

Term
|
Definition
| The uppermost pollen-receptive portion of the flower. |

Term
|
Definition
| The structure that develops from the ovary, the fruit protects the seed and is often pleasant-tasting. Animals eat the fruit and shit out the seed; the fruit is also important for seed dispersal. |
|
|
Term
|
Definition
| A reproductive structure that develops from an ovule in seed plants. It consist of an embryo and a food supply, surrounded by a hard seed coat. |
|
|
Term
|
Definition
| Thickened cell walls, and are usually arranged in strands to provide support for the plant. Can stretch out as the plant grows. |
|
|
Term
|
Definition
| The most abundant plant cells. They serve as action sites for photosynthesis and aerobic respiration. They are responsible for healing and repairing the plant. |
|
|
Term
|
Definition
| Hardened with lignin to provide structural support for the plant. Used for seed coats and the main ingredient in wood. |
|
|
Term
|
Definition
| Xylem forms the woody part of trees, and continuously carries water up the plant. Special cells called tracheids prevent water from backflowing down the plant. |
|
|
Term
|
Definition
| Phloem is responsible for carrying sugars and minerals around the plant in all directions by way of special structures called sieve tubes. Nutrients move from one cell to another thanks to tiny holes in the cell wall that act like a sieve. |

Term
|
Definition
| Waxy, lipid-based substance found on plant leaves that keeps water from escaping. |

| Guard cells open and close the stomata. |
