How do cells behave?
1. Cells do not move but have moving parts 2.Cells also sense and respond to a change, they also communicate with each other.
how are plant cells different from animal cells?
1. Plant cells have cell walls, and animal cells do not 2.Chloroplast
What is DNA?
1. a chemical shaped like a ladder 2. found in chrosones 3.small sections are called genes 4.deoxy ri bonucleic acid
What are 3 types of cells
1. branching 2. flat 3. round
What are some of the jobs of the skeletal system
1.Support system
What are some examples of organs?
Animal- heart, eyes Plant- flowers, roots
Are cell membranes found in an animal cell, a plant cell, or both?
Both
Are cell walls found in an animal cell, a plant cell, or both?
Cell walls are found in a plant cell
_______ are the most basic unit of living things
Cells
What size do cells have to be?
Cells have to be small enough to allow oxygen to reach all parts and big enough to hold all parts of the cell.
What is an example of a branching cell and how does it work?
Example- nerve cells 2. great length allows signals to move quickly.
What is an example of a round cell and how does it work?
Example- red blood cell 2. smooth shape to move through blood vessels and dimpled design
What is an example of a flat cell, and how does it work?
Example- skin 2. overlap to cover a surface

False, Plants have a cell wall, and animals do not!
True/False There is no limit as to how big or small a cell can be.
False, a cell has to be big enough to hold all it's parts and small enough to get oxygen to all it's parts.
_________ can be seen with a microscope __________ can't be seen with a microscope
Multi cellular organisms can be seen single cells can not
What are the needs of cells?
The needs of cells are food, waste removal, and gases.
True/False Chromosomes, which carry genes, are found in the nucleus of the cell.
True
True/False Mitochondria are used in the process of cellular respiration
True
True/False The process called respiration helps cells produce energy.
True
The part of the cell that allows sugar, oxygen, and water enter and waste products to leave the cell.
cell membrane
What are the parts of an animal cell?
cell membrane "skin" nucleus "brain" mitochondria "power plant" vacuoles "stomach" cytoplasm "gew"
The part of the cell that gives plant cells support and protection.
cell wall
The part of a cell that helps plants make food
chloroplasts
Material around the nucleus, surrounded by the cell membrane.
cytoplasm
What is DNA stand for?
deoxy ri bonucleic acid
The part of the cell that contains chromosomes.
nucleus
What happens during cellular respiration for animals?
oxygen and food go in Carbin Dioxide and water go in
structure that stores water and breaks down materials
vacuole
