What are the characteristics of a Dicotyledonae

1. Two cotyledons or seed leaves in the embryos

2. Principle veins leaf branches out from a mideridge forming a distinct network

3. Flower parts usually arrange in four to five

4. root system characterized by a woody taproot with branch roots growing from it

5. Stem with a vascular bundles in a single cylinder (rings)

6. THe cambium adds as ring of wood each year it grows

what characteristics of a Monocotyledonae

1. One cotyledons or seed leaves in the embryos

2. principle vein leaves are parallele to each other

3. Flower parts arranged in multiples of three

4. root system fibourous without taproot , all roots are the same size

5. stem with vascular bundles complexly arranged in the pith tissue

6. Stem and root without cambium, no annual ring added

What are the tissue systems of the plant

1. Dermal

2. Vesicular

3. Ground

What is dermal

A single layer of tightly packed cell covering the exterior of young plants. It acts as a protection as well as absorption surface with the enviornment (in the roots) or as a water weight barrier (as in stem and leaves)

What is the two types of vascular

1. Xylem: a complex tissue of several cells types which conducts water and dissolved solutes in a unidirectional flow form the roots to leaves

2. Phloem: A composite tissue that transports the products of photosynthesis from the production site ( mature leaves) to the roots.

What is ground

the remainder of a plant tissue that is netiher dermal nor vascula. It cells serve as a support for plant structer but as a sight for phototsynthetis and storage of the production

What is Osmosis

Osmosis is the movement of water molecules across a selectively permeable membrane from an area of higher water concentration (lower solute concentration) to an area of lower water concentration (higher solute concentration).

What is water potential

a measure of the potential energy of water per unit volume relative to pure water under standard conditions. It predicts the direction in which water will flow via osmosis, gravity, and mechanical pressure:

what is cohesion

the attractive force between like molecules—the tendency of molecules of the same substance to stick to one another.

What is adhesion

the attraction between different types of molecules the tendency of one substance to cling to a completely foreign surface or material.

What is surface tension

the property of a liquid's surface that allows it to resist an external force, acting like a stretched elastic membrane.

What is capillary action

is the ability of a liquid to flow through narrow spaces without the assistance of—and often in opposition to—external forces like gravity.

What is transpiration

the loss of water vapor from plant tissues, primarily through microscopic pores on leaves called stomata.
