Plant Cell (LAB) Flashcards
What parts of the plant cell are visible under 100x magnification?
nucleus
vacuoles
cell membrane
cell wall
an organelle that contains the photosynthetic pigment chlorophyll
chloroplast
photosynthetic pigment that caotures light and converts into energy
chlorophyll
carotenoid-accumulating plastids conferring color to many flowers and fruits as well as to some tubers and roots
chromoplast
chromoplasts are
plastids
contain colorful anthocyanins in their vacuoles, making the changes in the shape of the vacuole and the
plasma membrane easier to observe under a microscope
rhoeo discolor
non-protoplasmic materials
produced by plant cells as a result of metabolic activities
ergastic substances
These substances are typically stored within the cells and serve various functions, such as energy storage, waste disposal, or structural reinforcement.
ergastic substances
often found in vacuoles, cytoplasm, or cell walls
ergastic substances
Categories of ergastic substances
storage products
waste products
structural components
A primary energy reserve in plants, stored in plastids such as amyloplasts
starch
Stored in seeds, fruits, and other plant parts for energy storage
lipids
Stored in vacuoles or protein bodies, often found in seeds
proteins
A type of polyphenolic compound used for protection against herbivores and pathogens
tannins
Nitrogenous compounds that can have toxic or medicinal properties
alkaloids
examples of alkaloids
morphine and quinine
Waste products often stored as crystals in vacuoles to regulate calcium levels and deter herbivores
calcium oxalate crystals
needle-shaped calcium oxalate
crystals that are found in many plants
raphides
They are thought to act as a form of resistance against herbivory and can be unpalatable and sometimes
poisonous
raphides
A polysaccharide forming the primary component of plant cell walls
cellulose
A complex organic polymer that adds rigidity and strength to the cell walls of vascular plants, especially in woody tissues.
lignin
