Biology Basics
Name the two types of eukaryotic cells.
Plant and animal
This organelle is like the brain of the cell and holds our DNA
Nucleus
Name the four macros
Carbs, lipids, proteins, nucleic acids
Name the two types of transport a cell membrane can use to maintain homeostasis
Passive, active
What is the male gamete called?
What is the female gamete called?
Sperm, egg
Who discovered the cell?
Robert Hooke
This organelle is like the closet of the cell and stores water, nutrients, waste, etc.
Vacuole
A polysaccharide is a polymer of which: carb, lipid, protein?
Carb
Which type of transport does water use to get into/out of the cell?
Why do body cells undergo Mitosis?
to grow or repair
Name the 6 characteristics of life.
1. have Cells
2. Reproduce
3. Grow
4. maintain Homeostasis
5. Organization
6. use Energy
This organelle is only in plant cells and does photosynthesis.
Chloroplast
An amino acid is a monomer of which: carb, lipid, protein?
If a cell enters a HYPOtonic solution, what will happen to the cell?
It will swell and potentially burst
Name the 6 steps of cell division in order
Interphase
Prophase
Metaphase
Anaphase
Telophase
Cytokinesis
TRUE OR FALSE:
Changes in pH can make an enzyme no longer work
True!
Golgi Body
This macro is the most important in the cell membrane, making up the entire structure
Lipid
Which type of transport would a HUGE molecule like a protein use to get into or out of the cell?
Endo/exocytosis
What is the result of Meiosis?
- how many cells
- diploid or haploid
- genetically identical or unique
4 haploid cells that are genetically unique
What does it mean that water is "polar?"
Uneven charge (+/-)
This organelle digests and destroys things like Lysol.
Lysosome
Name the three types of lipids
Waxes, triglycerides, phospholipids
What does selective permeability of the cell membrane have to do with homeostasis?
By being able to choose what comes in/out of our cells, our cell membranes help us maintain homeostasis (balance)
What is the result of Mitosis?
- how many cells
- diploid or haploid
- genetically identical or unique
2 diploid cells that are genetically identical
