Characteristics of Living Things
All living things are made from _____.
Cells!
Where is the DNA stored in the cell?
Nucleus
Which cell (plant or animal) is the cell wall found in?
Plants only!
What structure allows things in and out of the cell?
Cell membrane
What is the function of the cytoplasm?
'Cell soup', holds all of the organelles in place.
What do living things need to grow and develop?
Energy!
Which structure is the powerhouse of the cell?
Mitochondria
What is the difference between plant cell and animal cell vacuoles?
Size! Plant cell vacuoles are much bigger than animal cells. They need this to maintain the cell shape.
Substances always move from areas of _____ concentration to areas of ______ concentration.
They move from high concentration to low concentration.
What is one reason an organism would develop to be multicellular?
1. Grow bigger = eat more things = get eaten by less things
2. Cells on the inside are protected = can live in more places
3. Cells can specialize
All living things must get rid of ______ due to its toxicity.
Waste!
What is the structure inside of the nucleus and what does it do?
Nucleolus: makes ribosomes
Which cell (plant or animal) are chloroplasts found in? What do they do?
Plant only! They do photosynthesis (and make plants green).
What is the term we use for the cell membrane that lets some substances through and blocks others?
Selectively permeable.
What is the function of the vacuole?
Stores waste, provides structure and support for the cell.
What is it called when living things respond to their environment?
Adapt!
What does a ribosome do?
Makes protiens
What is the function of the cell wall?
Protective, rigid, outer layer of the cell.
The diffusion of water through a selectively permeable membrane is...?
Osmosis
Does fluid movement in cells require energy?
No! Fluid movement relies only on concentration difference.
All living things must __________ to ensure the survival of their species.
Reproduce!
Which two structures look very similar in the cell (series of flattened sacs)?
Endoplasmic Reticulum (ER): Synthesis and transport of proteins
Golgi Apparatus: Sorts and packages other molecules
What are the general shapes of plant and animal cells (a quick way to differentiate between them)?
Animal: more circular
Plant: more square
Diffusion is... ?
The spreading out of particles from high concentration to low concentration until equilibrium is reached.
What is Ms. Jone's favourite food?
Ice Cream (obviously!)
