What is the term for getting rid of waste ?
excretion
What is the term for the structure where photosynthesis takes place ?
chloroplasts
What is found in the nucleus ?
DNA, genes, genetic information, genetic code
What is the function of a neuron ? [nerve cell]
Nerve cells carry impulses [messages] through he body.
How are nerve cells adapted to their function ?
Nerve cells are long to carry messages quickly through the body.
What is the chemical reaction that uses sunlight to react water and carbon dioxide called. ?
photosyntheis
Name the outermost structure on a plant cell.
cell wall
What is the term for the substance where many chemical reactions take place ? It is a jelly-like substance that fills the cell and holds the parts in place.
cytoplasm
What is the function of a red blood cell ?
Red blood cells carry oxygen around the body.
State two ways that red blood cells are adapted to their function.
1. Red blood cells have a biconcave shape to increase the surface area to absorb oxygen quickly.
2. Red blood cells have no nucleus, so that they can carry more oxygen.
A chemical reaction that uses glucose and oxygen as the reactants produces energy. What is the name of this process ?
respiration
What is the function of the cell membrane ?
The cell membrane controls what goes into and out of the cell.
What controls what goes into and out of the cell ?
cell membrane
What is the function of a cilitaed cell ?
To move mucus up and out of airways.
Describe how a ciliated cell is adapted to its function.
Cilitaed cells have hairs on them to move mucus up and out of airways.
Define sensitivity
detecting changes in the environment and responding
What is the function of mitochondria ?
This is where respiration takes place - to produce energy.
What are the three structures found in plant cells, but not animal cells ?
cell wall, chloroplasts, vacuole
What is the function of a root hair cell ?
Root hair cells absorb water [with dissolved nutrients] from the soil.
How is a root hair cell adapted to its function.
Root hair cells have a long finger-like structure that increases the surface area to absorb water more quickly.
define reproduction
The process by which organisms make new organisms like themselves.
What is produced by photosynthesis ?
Glucose is produced with oxygen as a waste product.
A group of identical cells working together form a ____________________
tissue
What is the function of a palisade mesophyll cell ?
Palisade mesophyll cells contain many chloroplasts to absorb light energy and produce glucose [chemical energy].
How is a palisade mesophyll cell adapted to its function ?
A palisade mesophyll cell has many chloroplasts so that it can photosynthesize [and produce glucose] quickly.
