Which cell structure is responsible for the storage of water in a plant cell?
ribosomes
vacuole
cell wall
nucleus
Which organelle is paired with its correct function?
cell membrane, stores DNA
ribosome, synthesize proteins
vacuole, makes ATP
chloroplast, transport materials
What determines instructions for a specific trait?
sequence of nitrogen bases
length of DNA molecule
number of nucleic acids in a DNA molecule
types of bases
Why are the number of chromosomes halved when forming gametes for sexual reproduction?
gametes have a single function and require less DNA
so offspring will have the correct number of chromosomes
to reduce the chance of mutations
the chromosomes in gametes are replicated strands of DNA

1 gram of carbohydrate
1 gram of protein
Which process requires energy?
diffusion
osmosis
passive transport
active transport
Which represents the first and last steps of protein synthesis?
DNA acts as a template for RNA production,amino acids bond
amino acids bond together, mRNA bonds to ribosome
tRNA bonds to codon, amino acids bond together
RNA leaves nucleus, attaches to ribosome
Enzymes are
carbohydrates
proteins
lipids
nucleic acids
During mitosis....
division of one cell into two identical cells
DNA is replicated within a cell
