a nutrient the body needs in large amount in order to supply energy and cellular building blocks
micronutrient
a nutrient the body needs in small amount to provide optimal cellular metabolism
nutrient
a component of food that performs a physiological function in the body l
essential nutrient
a nutrient the body needs in order to function but cant manufacture in adequate amounts and therefore must be part of the diet

what two molecules make up a plant cell wall
composed of cellulose and lignin
cellulose function
used to produce paper products, textiles, and as a potential base for biofuels
lignin function
found in cells providing support, protection, and water conductions
what does the cell wall enclose
the plasma membrane
What do the dots respresent
dark green drop- central vacuole
purple dot- chloroplast
Red dot- mitochondria
pink dot- cytoplasm
light green dot- nucleus
what are the four groups of gymnosperm
Gnetophytes, ginkgo, cycads, and conifers
what are the uses of wood
wood provides strength, insulation, versatility, and aesthetic appeal, and must harvest trees sustainably. The hardness of wood is determined by the strength of the cell walls and tied to lignin levels. Most softwood is uses for lumber
wood as lumbar
fell the trees, take to a sawmill, debark the log, lock for metal, cut into lumbar, and then dry lumbar. The grain of wood depends in the thickness of the cell walls.
wood as fuel
a primary source of fuel up until the Industrial Revolution. Burning wood is not very energy-efficient. Energy content can be increased if wood is turned into charcoal, and can be turned into pellets
wood as pulp
used to produce paper, cardboard, fireboard, rayon, cellphone, cellulose acetate
Wood products
Resins- are produced by trees as protection
Cork- is produced by the cork cambium as the epidermis of the trunk is replaced by the periderm
what are fungi mostly composed of?
hyphea
what are fungal cell walls composed of?
chitin
What may hyphae form?
mycelium
what are three methods fungi use to get nutrients?
from the environment, may be parasites, and may be mutualistic symbionts
Fungi produce food
can be used to ferment food (pickles), and can produce alcohol. Yeast produces alcohol and carbon dioxide breaking down sugar in the absence of oxygen
Fungi produce drugs
produces a chemical that inhibits the growth of bacteria, most wisely used as antibiotics today, and the first effective antibiotic was developed from penicillium.
What are the three different types of toxins produced in fungi
Protoplasmic toxins, Aflotoxins, and neurotoxins
Fungi can cause plant disease
80% of all plant diseases are caused by fungi, American chestnut. Blight, Dutch elm disease, Irish potato famine
How does fungi infect people?
It mostly affects the hair, skin, and nails. Ringworm is caused by fungi that break down kertain. Yeast infections occur in warm, moist locations on the body.
Fungi may be used as building materials
use mycelium to produce bricks or packaging, bicycling of demolition waste, and use mycelium to produce clothing.
where was coffee domesticated?
Native to the mountains of Ethiopia
what part of the coffee plant do we use? Is it a monocot or a dicot? How is it harvested?
We use the cherries produced by the plant. Coffee is a dicot. Coffee is made on a plant for decades, cherries from the plant are often picked by hand, and the cherries go through a wet or dry process.
where was cotton domesticated?
Domesticated multipiule times. First harvested in Peru 10,000 years ago, then domesticated in Sudan and India 7,000 years ago
what are the uses of cotton?
Cotton is spun into yarn or thread and then woven or knit into clothes; bleaching, mercerization to improve the strength and luster of fibers and affinity for dyes, applications of sizing to make fabric smoother and improve sheen, and applying finishes like permanent press.
