Structure and Function of Cells
All living this are made of ______
cells
'powerhouse of the cell' found in both plant and animal cells.
mitochondria
selectively permeable
What is the part of the cell cycle where cells spent the majority of time, and where the cells double in size and in its contents to prepare for cell division?
the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water.
photosynthesis.
Calculate the total magnification of a microscope of if the eyepiece lens is 10X and the objective lens is 40X
400X
What is the cell membrane?
The process by which molecules move from an area of higher concentration to an area of lower concentration
diffusion
Name the four stages of Mitosis
Prophase, Metaphase, Anaphase, Telophase
What does the following equation represent? Sunlight +6H20 + 6CO2--> C6H1206 +6O2
photosynthesis
What are three function of all cells
What word best describes how cell structures and organelles are suited to perform specific tasks or functions
specialized or specialization
Why do cells need to maintain homeostasis?
So they have all the chemicals they need to maintain life
During which stage of mitosis do chromosomes line up along the center of the cell?
What does the following equation represent? C6H1206 +6O2--> 6H20 + 6CO2 + Energy (ATP)
cellular respiration
The invention and improvements of microscopes have allowed a deeper understanding of cell function
Name three structures or organelles that are found in both plant and animal cells.
cell membrane, nucleus, cytoplasm, mitochondria, endoplasmic reticulum, vacuoles, golgi complex, ribosomes, vesicles, etc.
What would happen to a cell placed in extremely salty water?
A lot of water would leave the cell by osmosis, and the cell could die
Why does the cell need to replicate its DNA during interphase?
The cell replicates its DNA so that each daughter cell will have a complete set of DNA after cell division
Name a product of cellular respiration, that is a reactant in photosynthesis
carbon dioxide or water
Name all three parts of cell theory
1. All living things are made of cells
2. Cells are the basic units of structure and function on living things
3. All new cells are produced from existing cells
Name one organelle that animal cells have that plant cells lack, and one organelle that plant cells have that animals do not.
Animal cells- lysosomes
Plant cells- cell wall, chloroplasts
How could disease-causing bacteria get inside a cell without damaging the cell membrane?
If all single-celled organism of a species lost their ability to undergo cell division, what will happen to that species?
The organism will not be able to reproduce asexually. The species would become extinct.
List all the products and reactants of photosynthesis and cellular respiration.
Photosynthesis:
reactants- water, sunlight, carbon dioxide products- oxygen, glucose
Cellular Respiration: reactants- oxygen, glucose products- water, carbon dioxide, ATP
