A plant makes its own proteins but an animal synthesizes the proteins it consumes as food.
cell wall
A rigid structure that surrounds the cell membrane and provides support to the cell
annual plant bears fruit

seed
An adaptation of some terrestrial plants consisting of an embryo packaged along with a store of food within a protective coat.
genes
DNA segments that serve as the key functional units in hereditary transmission.
differentiate
Distinguish, tell apart, and recognize differences between two or more items.
onion cells

Borlaug
Green Revolution
Agriculture was not a developed science in ________ . That country's machinery, technology, and crop varieties did not advance with new developments in other parts of the world.
India
A plant makes its own proteins
Nitrates taken into the plant through the roots are pulled into the plant,
Proteins
Nutrients the body uses to build and maintain its cells and tissues
are Photosynthesis and respiration simple in design
Photosynthesis involves the use of energy from sunlight, water and carbon dioxide to produce glucose and oxygen. Cellular respiration uses glucose and oxygen to produce carbon dioxide and water.
meristem
Plant tissue that remains embryonic as long as the plant lives, allowing for indeterminate growth.
Photosynthesis
Plants use the sun's energy to convert water and carbon dioxide into sugars
onion cells
Plasmolyzed 5% saline (NaCl)
mitochondria
Powerhouse of the cell, organelle that is the site of ATP (energy) production
what consists of a protoplast
Protoplasm is composed of a mixture of small molecules such as ions, amino acids, monosaccharides and water,
green revolution
Rapid diffusion of new agricultural technology, especially new high-yield seeds and fertilizers.
store starch
Some plant roots and embryos, in the form of seeds and fruit, also serve as storage units for starch.
fermentation
The chemical action of yeast on sugars
The root cap cells
The dermal cells of the root cap that secrete mucus for lubrication and bacterial activity.
root cap cells
The dermal cells of the root cap that secrete mucus for lubrication and bacterial activity.
leaf
The major sites of photosynthesis in most plants.
what are Cell activities controlled
The nucleus maintains the integrity of genes.
flower
The reproductive structure of an angiosperm
What bodies break down food molecules.
The small intestine absorbs most digested food molecules, as well as water and minerals.
What is a good description of a simple cell
a neuron, most commonly found in the striate cortex.
root
a solution of an equation
