micro farming

yeah

Does a animal cell have a cell wall

no it does not

How many periodic elements

118

what are examples of macronutrients?

carbohydrates, proteins, fats, fiber, and water

What are examples of micronutrients?

phytochemical, antioxidants, vitamins, and certain minerals

what are Macronutrients in plants

Carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium, calcium, sulfur, magnesium.

What are macronutrients?

macronutrients are the nutrients required in large amounts

Iron, copper, zinc, manganese, nickel, boron, molybdenum, chlorine

what are rich macronutrients?

cereals, legumes, meat, fish, yams, potatoes, nuts, and oil seeds

What are rich micronutrients

vegetables, fruits, eggs, green leafy vegetables, fermented foods etc.

What are the micronutrients

micronutrients are the nutrients required in small amounts

What does a healthy cell do?

Follow a typical cycle: grow, divide, and die.

What does an goblet cell do?

prevent viral infections

What does an unhealthy cell do?

They multiply out of control

What does covalent bonds do

they share

What does ionic bonds do

transfer of electrons

What does NPK stand for

nitrogen, phosphorus, potassium

What does valance shell mean

Outer shell

What is a cell membrane

This is the protective barrier that surrounds the cell. It controls what enters and exits the cell, like a gatekeeper

What is a SER? (smooth endoplasmic reticulum)

Same function as the Rough Endoplasmic Reticulum, but without Ribosomes

What is an Amyloplast

Not found in animal cells. This organelle stores starch in some plants.

What is an cell wall

Only found in plants. This is a rigid layer outside the cell membrane that provides support and protection to the cell

What is an chloroplast

Only found in plants. This is where photosynthesis happens, allowing plants to convert sunlight into energy. They contain chlorophyll, which gives plants their green color.

What is an golgi body

This modifies, sorts, and packages proteins and lipids for transport out of the cell or to other parts of the cell.

What is an mitochondria

These are the powerhouses of the cell. They generate energy for the cell by breaking down sugars and converting them into energy-rich molecules called ATP.

What is an nucleus?

This is the cell's control center. It contains the cell's DNA, which contains instructions for making proteins and controlling the cell's activities.

What is an RER ( rough endoplasmic reticulum )

This is a network of membranes that helps in the production of proteins and lipids. This has ribosomes.

What is an ribosome?

These are the sites where proteins are made. They can be found floating freely in the Cytoplasm or attached to the Rough ER

What is an stem cell

can self-renew, can become other cellsW

What is an Vacuoles?

These are storage sacs within the plant cells (also found in animal cells. There are more but smaller). In plants they store water, nutrients, and waste products.

What is the definition of biennial

a plant that blooms in its second year and then dies

What is the lewis dot theory

combined observations at the time about chemical bonding together

What is the shape of an animal cell

round, irregular shape

What is the shape of an plant cell

square or rectangular

Whats the definition of annul

A plant that usually germinates, flowers, and dies in a t=year or season

Whats the definition of organic

no use of chemical fertilizers or pesticides in growing and processingof foods

Whats the definition of perennial

a plant that lives for more than 2 years

Whats the definition of sustainable

capable of being continued with minimal long-term effect on enviroment

What are the three main elements of good soil

nitrogen phosphorus potassium ( NPK )

Magnesium deficiencies

Paleness from leaf edges no spots edges have cup shaped folds. leaves die and drop in extreme deficiency

Phosphorus defciencies

plant short and dark green. in extreme deficiencies turn brown or black. bronze color under the leaf

Potassium deficiencies

small spots on the tips edges of pale leaves. spots turn rusty folds at tips

Nitrogen deficiencies

Stunted growth extremely pale color. upright leaves with light green/yellowish. appear burnt in extreme deficiency

is a nonmetal and a nonmetal an covalent bond or ionic bond a

Covalent

is a nonmetal and a nonmetal a polar or non-polar

it is neutral almost

is a nonmetal and a metal make a ionic bond

yes it does

does gaining an electron make it negative or positive

negative

does receiving an electron make it negative or positive

positive

Periodic table of element notes

if a compound is made from a metal and a non metal, its bonding will be ionic

NUMBER OF ELECTRONS IN THE VALENCE SHELL

number of electrons in total the number next to the symbol.
