Vascular Plants |
Plants that contain xylem and phloem which are vascular tissues. |
Seed bearing plants, gymnosperms and angiosperms.
Pteridophytes, ferns, lycophytes, and horsetails.
|
|
Lignin |
Strengthens and makes plants rigidity, is a hard organic compound. |
Supports cellulose fibers in the cell walls.
Gives power. |
|
Xylem |
A non living tube shaped tissue. |
Found in vascular system plants.
Carries the water from the roots to the rest of the plant. |
|
Phloem |
Transports sugar and organic nutrients to the plant. |
Found in the vascular system plants.
Elongated tubes. |
|
Tracheids |
Conducts water and supports the xylem. |
Made of long, thin cells that have tapered ends and hardened walls.
Maintains a structure. |
|
Vessel elements |
When combined with other cells forms a tube that transports water and minerals. |
Is a short wide cell.
Needs to form with other cells to function. |
|
Cohesion |
When molecules of the same substance bind together. |
Just like water molecules they stick together.
Mold together. |
|
Adhesion |
When two substances that are different are attracted. |
Opposites attract.
Peanut butter and jelly. |
|
Sieve tubes |
Phloem cells in a column. |
-found in plants
- many of the same cells together. |
|
Endosperm |
Provides nourishment to developing embryo in seeds of flowering plants. |
Made from the Union of sperm cell and a large cell with 2 nuclei |
|
Cotyledons |
A single or double seed leaf of a flowering plant embryo. |
First leaves of a seedling
A angiosperm |
|
Apical Meristems |
Allows the shoot/root to increase in strength. |
Produces auxin
Gives stability |
|
Seed coat |
The outer covering of a seed that is tough and protective. |
When it's cold we put on coats
Warm, shell like. |
|
Germination |
When seed begins to sprout. |
Beginning to grow.
Opening a present. |
|
Primary growth |
The growth in vascular plants. |
Equivalent to growth spurts in humans.
Changes the plant. |
|
Node |
The part of the stem of a plant that connects other leaves, forms a bump. |
Connector
Part of the branch |
|
Root cap |
It is found at the rip of the root, is a tissue. |
Baseball caps are worn on out heads ^
"Cap it off" |
|
Epidermis |
The tissue that is the outer layer of a plant. |
Our skin is a epidermis
Made out of cells |
|
Cuticle |
Is the outmost layer of a living tissue. Prevents water loss and infection of parasites. |
Kind of like a bandage.
Not dead like the cuticle on our finger nails. |
|
Vascular tissue |
Apart of the vascular system. Water and nutrients are conducted through the tissue. |
Transports
Provides important factors |
|
Ground tissue |
A tissue made up of 3 cells, parenchyma, collenchyma, and sclerenchyma. Forms pith/cortex of leaf. |
Takes up space
A base/support for the plant |
|
Secondary growth |
The process that which causes the stems and roots to thicken |
Elongation occurs
Causes a change |
|
Vascular cambium |
Is found between the xylem and phloem. |
Found in vascular growth
Is the middle of a "sandwhich" |
|
Pericycle |
A layer of cells, is the place where you can locate parenchyma or serenchyma cells. |
Storage space
Home |
|
Plant growth regulations |
Chemical substances that change the growth, changing the cells, tissues, and organs in the plants. |
Modifying
Boosting/unboosting |
|
Auxins |
Modifies the growth of the root formation, bud growth, and the fruit and leaf drop. |
Changes
Unnatural |
|
Gibberellins |
Plant hormones that help the plant grow and develop. |
Stem elongation Dormancy Germination Flowering |
|
Cytokinins |
Promotes cell division in the roots and shoots. |
Occurs in the base of the plant
Take an action in something |
|
Abscisic Acid |
A plant hormone that is active in the plant development. |
Active in the changes of a plant.
Growth |
|
Ethylene |
A chemical substance that helps the growth of a plant. Especially like preventing leaves from elongating. |
Linked to auxin
Can help fruits ripen |
|
Tropism |
An involuntary, positive or negative reaction to a stimulus source. |
Good or bad
Behavior |
|
Phototropism |
Plant growth due to light. |
Reacts with auxin
Also happens in fungi, not humans. |
|
Gravitropism |
When a plant grows or turns in the force of gravity |
Adaptation
Movement |
|
Photoperiodism |
The way plants respond to the change of seasons and time/light change. |
Adjustment.
Changing to the world around. |
