2.3-2.4 Flashcards
the basic structural unit of all living things
cell
what surrounds the cell, separates it from its environment, and regulates what enters and leaves the cell
cell membrane
what is the control center of the cell
nucleus
what is the fluid medium of a cell
cytoplasm
what is an insoluble substance which is the main constituent of plant cell walls and of vegetable fibers such as cotton. It is a polysaccharide consisting of chains of glucose monomers.
cellulose
A complex organic polymer deposited in the cell walls of many plants making them rigid and woody(only woody plants have)
Lignin
what is the Tiny chemical “Factories” that uses light to manufacture food.
chloroplasts
what is a green pigment, present in all green plants and in cyanobacteria, responsible for the absorption of light to provide energy for photosynthesis.
Chlorophyll
a space or vesicle within the cytoplasm of a cell, enclosed by a membrane and typically containing fluid.
Vacuoles
he process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water.
Photosynthesis
Organisms that make their own food
Autotrophs (or producers)
an organism deriving its nutritional requirements from complex organic substances (eats stuff)
Heterotrophs (or consumers)
yellow leaf colors
Xanthophyll
Yellow/orange
Carotene
Red/blue/purple
Anthocyanin
The process by which a plant loses water vapor through its leaves and stems.
Transpiration
the long stem that you put your eye on on the microscope
Eyepiece/ ocular lense
the rotation thing that the zoom in things are connected too
nose piece
the long stem that attaches the part you put your eye on
body tube/eyepiece tube
the zoom in thingies
objective lenses
pieces that hold the glass sample
stage clips
the part you put the glass sample on
the stage
the part below the stage hole
the diaphragm
light source
illuminator
the long handle thing you grab that connects the eyepiece tube thingy to the rest of the thing
arm
the knob attached to the arm
coarse focus
the knobs attached to the bottom of the stage plate
fine focus
the bottom of the microscope that you also hold
base
the eyepiece is already zoomed in how much
10x’s as much
the formula of photosynthesis
6CO2+6H2O+photons–>C6H12O6+6O2
or (6 carbon dyoxide + 6 water+photons –> glucose + 6 oxygen
Examples of special leafs
tendrils, bud
scales, spines, fleshy storage leaves
What is a special leaf?
S special design for a special task, and can also be called a modified leaf
insectivorous plants hold what chemichal
chlorophyll
what does chlorophyll do
gets nitrogen from bugs
what is the layer of cells that detaches the petiole from the stem
absision layer
what is the study of living things
biology
what are living things
organisms
what is the study of plants
botany
the study of the human body
human anatomy
the study of how the human body’s systems and functions work together to maintain a stable and internal environment
human physiology
not woody plants
herbs
