Parenchyma Cells
Cells found in the leaf that have thin cell walls and large vacuoles for photosynthesis, food storage and respiration
Collenchyma Cells
Cells found in the stem that have thick and stretchy cell walls to help create support
Sclerenchyma Cells
Cells found in fibers that have thick cell walls to create a system of support
Dermal Tissue
Tissue that makes up the epidermis in most leaves. It helps the plant prevent dehydration by absorbing H20
Vascular Tissue
Tissue that creates the veins of the plants in the center of roots, stems and leaves. They transport water and nutrients and provide a network of support throughout the plant. There are two types: Xylem and Phloem
Ground Tissue
Tissue that makes up most of the roots. Their main function is storage and support.
Meristematic TIssue
Tissue that consists of dividing cells. It is found wherever there is new structure forming in a plant.
Roots
Two functions: 1) Support the plant 2) Provide water and food to the plant
Leaves
Used to gather light and accomplish photosynthesis. Gases are also exchanged in the leaves in a process called Transpiration.
Epidermis
Single layer of cells that cover the lower and upper sides of the leaf. They are covered with a cuticle on the outer wall. There are many stomata perforating the lower surface.
Functions of the Epidermis
Protects the internal issue from injury
Function of the cuticle
Prevents water loss
Mesophyll
Made up green tissue of the leaf that consists of thin-walled cells containing chloroplasts, this tissue forms the bulk of the leaf. It is differentiated into the Palisade Parenchyma and the Spongy Parenchyma. There is a system of air spaces which communicate with the air chambers behind the stomata.
Palisade Parenchyma
Consists of thin-walled cells which are usually cylindrical in shape. It is responsible for photosynthesis because they contain chloroplasts
Spongy Mesophyll
Ball-shaped with large intercellular spaces. The function of it allows for the interchange of gases
Veins
Consists of branched vascular bundles. These vascular bundles include Xylem and Phloem
Xylem
Conducts water and dissolved ions to the mesophyll tissue
Phloem
Conducts organic food such as glucose from the mesophyll to other parts of the plant
Stomata
Communicates with the air chambers in the spongy mesophyll. Formed by a pair of guard cells.
Guard Cells
Have the ability to open and close the stoma
Function of the stomata
THe stomata are responsible for the interchange of gases for respiration and photosynthesis. The stomata allow for the loss of excess water in the form of water vapor, which also allows for cooling
Sepal
The outer most ring that covers and protects the flower bud
Stigma
Stick tip to catch pollen at the end of the style
Filament
Thin stalk-like structure that holds the anther
Peduncle
This bulk-like structure connects the flower to the stem
Ovary
THe protective "organ" inside a flower that bears many seeds or "female" eggs
Petal
Modified leaves usually on the second ring of a flower. Can be different colors
Style
Narrow structure that is found on the pistil that connects the ovary
Anther
Stalk at the top of the stamen that makes and holds pollen or "male sperm"
Corolla
All the petals together are referred to as this
Stamen
The male reproductive "organ" of a flower
PIstil
The female reproductive "organs" of a flower
Cross-pollination
When seeds from one plant 'cross' to another plant
Self Pollination
When a plant's seed drops into its own reproductive organs
