Science Unit 5 Flashcards
What are two types of genetic material, what do they do?
DNA and RNA, help make proteins
What is an example of an internal stimulus, and external
Internal- feeling hungry
External- getting scared
What is the goal of evolution
Have the highest level of reproductive fitness to ensure your genes to survive to the next generation
Can determination be reversed?
No
What is apoptosis
Programmed call death which can be a normal part of cell development
Why don’t all cells look the same
There different cell jobs, and structures
What cells do prokaryotic, and eukaryotic have in common
Both cells have some type of DNA, ribosomes, cytoplasm, cell membrane, hereditary material, and have a small size
What makes prokaryotic, and eukaryotic different
Prokaryotic cells have no nucleus, no membrane bound organelles, and has circular DNA. Eukaryotic has all of those things + linear DNA
What are examples of Pro cells
Bacteria, algae
Examples of eu
Plants and animals, fungi
What are three domains of life
Bacteria (pro) algae (pro) eukaryotic (eu)
Why cells do pants have and not animal
Chloroplast, cell walls
What is the difference between RER and SER
RER- full of ribosomes, fit for protein
SER- fit for lipid
What is the meaning of semipermeable membrane
Picky
What makes mitochondria and chloroplast different from other cells
Have their own DNA
Reproduce on their own, separate from all.
What does cytoskeleton do for the cell
Gives shape, makes proteins, to help stuff move
What two things do centrioles make
Cilia and flagella that help the cell move
What doc centrosomes do
Make centrioles help cell move
What are vesicles and what do theydo
Temporarily transport, a simple cell membrane sac
