Can You Cell?
directs all cell activities and contains genetic material, DNA.
Nucleus
DNA is made up of:
nucleotides
Describe the growth process of a baby
Cells multiply -> create organs -> create a baby
contains genetic information (DNA)
Nucleic Acid
What can regulate the functions of tissue and organs, carry material throughout the blood, and repair cells and tissues?
Proteins
moves materials within the cell and moves materials out of the cell.
Golgi body
What is DNA shaped like?
Double helix
breaking down food into simpler substances that can be absorbed.
Digestion
the process in which DNA molecules make exact duplicates

Answers will vary
produces energy through chemical reactions, breaking down fats and carbohydrates. Recycles and decomposes proteins, fats, and carbohydrates.
mitochondria
found in the nucleus. Made of DNA and contain instructions for traits and characteristics.
chromosomes
using gases to produce energy
Respiration
the breaking down of food molecules by cells into usable energy
