Lesson 7 Flashcards
What are the three parts of the cell theory?
- All living things are composed of cells.
- Cells are the basic units of structure and function in all living things.
- All cells come from preexisting cells.
How would you be able to recognize a prokaryotic cell under a microscope?
They are simpler, smaller, and do not enclose their DNA in a nucleus.
What cells enclose their DNA in a nucleus
Eukaryote
What do all cells have in common
All cells have a membrane
What kind of organisms are all considered prokaryotes
Bateria
If you look at a cell and it has a large membranous structure with a very dense dark spot in it what cell is this?
Eukaryotic cell
What does a nucleus do
assembles and produces ribosomes.
What is the relationship between the nucleus and cytoplasm?
The nucleus is contained in the cytoplasm
The nucleus is the site for what production?
ribosomes
What organelle breaks down other organelles and other cells?
Lysosomes
What organelle stores salts and water?
Vacuole
What structure makes proteins and where are these made?
The structure is the Ribosomes and the Nucleus are where they are made.
What organelle modifies and sorts proteins?
Golgi Apparatus
What organelle converts chemical energy in food to compounds that the cell can use to make energy?
Mitochondria
Which two organelles are involved in energy conversion?
Chloroplast and Mitochondria
What organelle is specific to plant cells but never animal cells?
Chloroplast
What is the function of the cell wall?
Support and protect the cell
How is the cell wall different than the cell membrane?
Cell walls let water, oxygen, carbon dioxide, and other substance easily pass through them but cell membranes regulate what comes through
What never has a cell wall?
Animal cells
What is the primary function of the cell membrane?
to regulate what enters and leaves and to protect and support the cell
How do prokaryotes and eukaryotes differ? 2 main reasons. Compare and contrast.
Prokaryotes differ from Eukaryotes because they do not enclose their DNA information in nuclei and Prokaryotes do not have as many specialized cells. Prokaryotes and Eukaryotes are similar because both of the cells can contain ribosome, cell membranes, cell walls, and cytoplasm.
What surrounds all prokaryotic and eukaryotic cells
Cell membrane
Where are ribosomes made of
Nucleolus
What makes rough ER easy to identify
they are covered in ribosomes
Where are protein synthesizers made and where are most of them located
Ribosomes
What is the most dense area of the cell
Nucleolus
Where is the cell’s genetic information found
Chromatin
What is the largest structure in a plant cell
Vacuoles
If a cell needs a lot of protein molecules what do they need a lot of
ribosomes
