Organism - answer A living thing
Cells - answer The basic unit of structure and function in all living things
Complex Organisms - answer Organisms that consist of many different types of cells
Osmosis - answer Water passes through the membrane to even the concentration of
protein on both sides
Diffusion - answer Molecules move from a place where they are highly concentrated to
one where the concentration is lower
Active Transport - answer Material moves with the help of protein energy from low to
high concentration
Nucleus - answer Contains all DNA, the brain of the cell
Cytoplasm - answerJelly-like substance outside of the nucleus where the organelles are
Organelles - answerSmaller structures within the cell that have specific roles
Mitochondria - answerMake energy in the form of ATP
ATP (adenosine triphosphate) - answerThe protein making ribosomes
Lysosomes - answerHold enzymes that can break down molecules (digestion)
Vacuoles - answerHold water and nutrients in the cell
Endoplasmic Reticula (ER) - answerTube which carries material from the cytoplasm to
the nucleus
Golgi apparatus - answerModifies proteins for movement through the cell
Cell wall - answerMade of cellulose and makes a firm surrounding for the cell while still
allowing movement in and out
Chloroplasts - answerContain chlorophyll and are involved in photosynthesis, using
energy from the sun to produce their own food
, Glucose - answerSugar that is made for food during photosynthesis
Autotrophs - answerCreates their own food (energy)
Heterotrophs - answerConsume foot to get their energy
Tissues - answerSimilarly specialized cells grouped tohether
Organs - answerGroups of similarly functioning tissues
Organ System - answerGroups of organs working together
Vestigial - answerOrgans left over from evolutionary time that do not have important
functions
Stamen - answerThe male part of a plant's reproductive system which uses anther to
make pollen
Pistil - answerThe female part of a plant's reproductive system which has an ovary and
egg cells
Digestive system - answerMouth, stomach, and intestines
Respiratory System - answerNose, lungs, and diaphragm
Circulatory System - answerHeart, veins (thing) and arteries (thick)

Skeletal System - answerBones and ligaments
Nervous System - answerBrain, spinal cord, and sensory organs
Muscular System - answerSkeletal, cardiac, and smooth muscles
Endocrine system - answerglands
Excretory (renal) system - answerkidneys
Reproductive System - answerMale and females reproductive system
Immunological System - answerLymphatic System
Asexual reproduction - answerOffspring comes from a single parent such as bacteria or
fungi
