The simplest collection of matter that can be alive?
Basic features of all cells?
Phospholipid cell membrane
Semifluid substance called cytosol
Chromosomes (carry genes)
Ribosomes (make proteins) Instructions
The plasma membrane controls the movement of molecules into and out of the cell, a trait called?
genetic instructions are housed in the nucleus and carried out by the?
Ribosomes use the information from the DNA to make?
This organelle modifies proteins before they leave the cell
Rough Endoplasmic Reticulum
Once proteins are synthesized and ready for transport they are put into ________ to be sent to other places to perform functions
Which organelle does the protein get processed? (the post office of the cell)
? is a membranous sac of hydrolytic enzymes that can digest macromolecules
Lysosomal enzymes can hydrolyze?
Organelle that uses cellular respiration, a metabolic process that uses oxygen to generate ATP
Build up ATP by eating food
All organisms have
a network of fibers that organizes structures and activities in the cell?
What does cytoskeleton provide?
Helps move things around (cilia, flagellum)
involved in transportation
Gives it shape
Mitochondria has it's own set of ?
Provided only by the mother
genes (mitochondrial DNA)
What processes must a cell perform?
What type of reproduction involves inheritance of all genes from one parent, cloning, and is the vast majority of reproduction within our body?
Why is sexual reproduction important and vital to life?
Sexual reproduction is to provide variety of off spring
Variety provides for survival for the future
chromosomes are composed of ?
What is contained in chromatin?
DNA + proteins (within the nucleus)
Allows passage of hydrophilic substances across the membrane
The process where molecules move from an area of high concentration to an area of low concentration until everything is the same concentration?
The diffusion of water across a membrane is called?
indicates that the concentration of a solute is the same on both sides
indicates that the concentration of solute is higher outside the cell
indicates a lower concentration of solute outside the cell
Cells have a mechanism for moving a solute against its concentration gradient
It requires the expenditure of energy in the form of ATP
Why is it important to have more surface area?
Surface area allows us to make exchanges with outside environment, making survival easier
