False.
Why do animals and humans need proteins in their diet?
they break down protein into amino acids needed for their particular protein synthesis
Four stages in growth are (in order):
- Birth - Growth - Maturation - Death
What conditions and/or raw materials are necessary for photosynthesis to occur?
- chlorophyll - CO2 - H2O - light
Jan Baptista's experiments showed:
- loss of soil mass < gain of plant mass - gain of plant mass related to water
Priestly's experiments explained:
- plants are associated with O2 - animals require O2
Four parts of a seed are:
- seed coat - cotyledon shoot tip - endosperm root tip - embryo
What is the function(s) of ATP?
- stores the initial energy released by respiration - provides the energy for all cytoplasmic chemical synthesis

A plant makes its own proteins but an animal synthesizes the proteins it consumes as food.
False.
Current populations experiencing famine are primarily the result of lack of land to grow more plants.
False.
The first chemist to begin quantifying the process of photosynthesis was:
Nicholas de Saussure
Meristematic cells of different kinds of plants may look alike, but the DNA messages are different.
True.

produce a carbohydrate from CO2
The function of ribosomes is _________ synthesis.
protein
Match the associations with the "light" and "dark" phases of photosynthesis:
solar energy - light CO2 intake - dark release of energy - dark storage of energy - light release of O2 - light release of water - dark ATP - light forms carbohydrates - dark
