Cells
Where are proteins made?
In the ribosome
What are the four stages of mitosis?
prophase, metaphase, anaphase, telophase
How many sister cells does mitosis produce?
How does an organism use energy?
It uses energy to move a molecule from low to high concentration by active transportation.
What does the cell membrane do?
It controls comes in and out of the cell
What is budding?
a type of asexual reproduction where a new organism develops from a bud or outgrowth that forms on a parent cell
What happens to the nucleus during the mitosis stage?
The nucleus divides into two nuclei
What process is happening when bread dough rises?
The yeast are performing fermentation
How does oxygen move through the membrane?
From high to low concentration by passive transport
What are the mitochondrion considered?
They are considered the powerhouse of the cell
What are gametes?
Cells formed for sexual reproduction
Describe what happens during the anaphase stage
The chromosomes separate at the centromeres.
Describe what happens during the interphase stage
The cell grows and duplicates its DNA
Describe what happens during cytokinesis
The cell membrane pinches the cytoplasm into two cells.
What happens to the cells in asexual reproduction vegetative reproduction?
Parts grow out of the parent plans and become individual plants
How many sister cells does meiosis produce?
Four
Describe what happens during the metaphase
The chromosomes meet down the middle
Describe what happens during the telophase stage
The chromosomes uncoil; two new nuclear membranes form.
An ion move through the cell membrane, using the channel of an embedded protein is called what?
Facilitated diffusion
What happens to the cells in asexual reproduction binary fission?
An unicellular organism splits into two identical cells.
What two processes are opposite process involving the same substances?
Cellular Respiration and Photosynthesis
Describe what happens during the prophase stage?
DNA forms x-shaped chromosomes and spindle fibers appear
Which type of passive transport moves molecules with the help of protein?
Facilitated Diffusion- allows molecules to move across a cell membrane with the help of proteins
Which type of passive transport moves water?
Osmosis- movement of water from low concentration to high concentration
Which type of passive transportation moves molecules across the membrane?
Diffusion- moves molecules across a membrane from a high concentration to a low concentration
