Sections 9.1, 9.2 & 9.3!!!!!

Relationship btw. distribution of tissue in the leaf - The leaves on plants usually have a Waxy Cuticle, which covers the whole plant and this helps to reduce water loss. This waxy substance is a epidermis that covers the whole plant helps to protect the plant against infections. In the plant a Palisade Mesophyll helps to bring to the leaves of the plant to get packed with cells, good air space, absorption of light and is the PRIMARY site of photosynthesis. Spongy Mesophyll, is a lower rank of Palisade. Thus from this, XYLEM helps to send water and minerals to travel through out the leaves. The PHLOEM helps to gather sucrose to send it off to photosynthetic products to non-photosynthetic productions of the plant. The STOMA or the guard cells, they help to form borders of stomata, opening which open or close letting gas exchange when opening and closing when stopping water from entering.

Identifying the roots, stems and leaves- Bulbs: modified leaves, e.g. onion, garlic. 

Tubers: modified stems, e.g. potato, gladiola.

Storage roots: e.g. carrots

Tendrils: modified leaf e.g. ivy.

Comparing Growth of Apical & Lateral meristems in Dicot- Meristems are regions where cells continue to grow and divide mostly during the life of a plant. Apical meristem increase the length of the plant and creates more leaves and flowers. Lateral meristem are found in vascular boundless and increase the diameter of the plant creating xylem and phloem. (end 9.1)

How does the root system large amounts of Minerals- Well there is an extensive Branching of roots greatly increasing the overall exposure of the root system extracellular fluid. Root hairs are individual roots cells that grow extensive which increases the surface area greatly with epidermal cells to extracellular fluid.

Process of mineral ions absorption from the soil- Active transport is used to concentrate mineral ions in the root. Active transport requires ATP to bring oxygen. The ATP oxidation helps to pump protons from the inside out of the root producing H+ membrane potential. 

How water is carried by transpiration stream- Thick walled vascular elongated tissue cells, which are arranged end-to-end & connected by perforated end-plates.

Xylem cells die at maturity, leaving a continuos microtubules for transporting water and dissolved material ions. from the root above ground portions of the plant. (end 9.2)

Distinguish Between- Pollination: The transfer of pollen grains from the anther to the stigma. 

Fertilization: Fusion of male and female gametes

Seed Dispersal: Mechanism for distributing seeds away from the parent plant.

Conditions for Germination- Seeds adopted to the terrestrial life. Seed democracy increases chances for that to germinate which are also environmental cues. (end 9.3)

Kingdom of my PLANT!!!!

Class- Gymnospermae, which means plants that don’t produce leaves.

Order-  My plant is a Monocot, so at the end of Pathos it will take the ending letters of  ales. Which would be Pathosales because its a Monocot and its under the Superorders.

Family- The family of a plant depends on the highest classification that it’s given. 

Genus- The Genus of a plant is for those plants that are commonly known.

Species- The species of a plant is usually determined by the flower color, size or shape of the leaves and it’s original habitat. 

The Differences between Monocots and Dicots

Monocots- Have ONE cotyledon, also the veins on the leaves are parallel and monocots also have FIBROUS roots.

Dicots- Have TWO cotyledon, also the veins on the leaves are net-like and dicots have TAPROOTS. 

Basic info on my PLANT!!!!!

My plant that I have worked with is called a Golden Pathos plant. This plant originates in the Solomon Islands, which is typically a warmer climate. This plant is a small version of a vine that does not produce any flowers an can only grow about 18” tall unless it is grown on a pole.

These plants are typically found in the United States inside houses. The Golden Pathos plant is a plant to show natural beauty in doors.
