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
True!
This organelle is like the closet of the cell and stores water, nutrients, waste, etc.
Vacuole
_________ make up our cell membranes and function as long-term energy storage
Lipids
What is the movement of water in/out of cells called?
Osmosis
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
Crossing over and independent assortment ONLY happen during...
Meiosis
If a cell enters a HYPOtonic solution, what will happen to the cell?
It will swell and potentially burst
What is the difference between DIPLOID and HAPLOID cells?
Diploid = chromosomes are paired (ex. arm cells)
Haploid = chromosomes unpaired (ex. sperm)
True or False: Animal Cells do NOT have Chloroplasts.
TRUE
Golgi Body
What are the "Strings" called that attach to chromosomes during Cell Division to pull them apart?
Spindle Fibers
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 holds the cell together?
Cell Membrane
This organelle digests and destroys things like Lysol.
Lysosome
TRUE OR FALSE: When we eat protein in steak, because cows are animals just like us, we can directly use their proteins for functions in our bodies.
False!
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
