OTHER CELLS
This organelle serves as the cells boundary
cell wall or membrane
Diffusion
If a daughter cell contains 8 chromosomes after mitosis how many chromosomes did the parent cell contain?
8
Proteins are made from what small organelle
Ribosomes
One characteristic of eukaryotes is...
A particularly active cell may have large numbers of this organelle
Mitochondria
This type of transport moves larger molecules like glucose
facilitated diffusion
Which level of organization is represented by a group of different tissues working together to perform a complex function?
Organ
What makes stem cells different from other cells in the body?
They are undifferentiated cells that can turn into a number of different kinds of cells as needed
What organisms are eukaryotes?
Humans, animals, plants, protozoa
Cells store many things like water, salt and protein in these sac like structures
When a white blood cell captures bacteria
Endocytosis
During Interphase a cell grows, duplicates organelles and...
doubles its DNA
All cells contain these three things....
1. some sort of membrane
2. internal fluid like cytoplasm
3. central zone that has a nucleus or contains the genes of the cell
Three organelles that plant cells have that animals cells do NOT
Cell wall, central vacuole, chloroplast
These three things make up the cell membrane
Phospholipids, cholesterol, proteins
Gummy bear lab, the reason your gummy bears swelled or shrank
osmosis
Why is it important for cells of multicellular organisms to undergo mitosis?
Mitosis produces cells that are identical to the parent (aids in repair of body cells)
If a cell does not go through the S phase of the cell cycle before mitosis, what might be wrong with the daughter cells?
The daughter cells would have the wrong number of chromosomes (specifically half)
Two purposes of the cell cycle
growth and repair
These three structures are a part of the cell membrane
phospholipids, carbohydrates, proteins
Put A for active or P for passive transport
1) Requires energy
2) Moves particles from an area of higher concentration to a lower concentration
3) Used to transport water
4) Moves particles against the concentration gradient from areas of lower concentration to a higher concentration
1) A
2) P
3) P
4) A
What happens during Prophase? (3 things)
Chromosomes condense and are visible as sister chromatids (in X’s).
Nuclear membrane disappears.
Spindle fibers form out of centrioles.
1. All living things are made of cells.
2. Cells are the basic unit of life.
3. All cells come from other cells.
