Cell Theory
The smallest living thing
What is a cell?
A part of a cell that carries out a specialized job
What is an organelle?
This is the smallest unit of matter
What is an atom?
This process is when particles move from an area of high concentration to an area of low concentration
What is Diffusion?
A solute plus a solvent equals this scientific term
What is a solution?
Cells do this for living things (up to 5 possible answers)
1. provide structure/ support
2. allow bodies to grow
3. allow bodies to reproduce
4. turn food into energy
5. carry out specialized jobs
This organelle holds our DNA and is responsible for controlling the actions of the cell
What is the nucleus?
This level of organization builds organs in the body
What is tissue?
Osmosis is the diffusion of a liquid through a _________________ membrane from an area of high concentration to low concentration.
What is semi-permeable?
This is how water moves from the stomach to the brain
What is the blood?
This is an example of something that has cells
What is anything alive now or that once was alive and has not decayed! Ex: Tree, Person, Ladybug, Dead Plant, Lion, Mushroom
The function of the cell membrane is this
What is to control what enters and exits a cell?
When many organs come together to complete similar functions they are called this
In an isotonic solution, water moves like this in a cell
What is water moving in and out of a cell equally?
This organelle is larger in plant cells than in animal cells
What is the vacuole?
Cells must come from these
What are other, preexisting cells?
This organelle is the place where CO2, water, and sunlight are converted to oxygen and glucose.
What is the chloroplast? (Photosynthesis!)
This system in the body is known for the ability to collect sensory information and send command signals throughout the body from the brain
More solutes INSIDE the cell means the cell is in a(n) _____________ state.
What is Hypotonic?
Only plants can go through the process of photosynthesis, so animals must find the glucose they need for cellular respiration using this
What is searching for and eating food that they do not make?
An example of a cell shape matching its function is this
This process takes place in the mitochondria and is responsible for producing ATP energy for the body
What is Cellular Respiration?
All 9 levels of organization in order from smallest to largest
What are atom, molecule, organelle, cell, tissue, organ, organ system, organism, population?
A cell has 3% salt inside and the body has 9% salt around it. The solution is in a __________ state and water will move _______ the cell.
What is hypertonic, out of?
A body that has had too much water needs emergency care! Adding more of this to the body will help stabilize the system
What are solutes?
