Bio Flashcards
Cell
Small unit that makes all living organisms and tissues
cell membrane
semipermeable membrane surrounding the cytoplasm
organism
single celled life form like animal and plants
DNA
In nearly all living organisms that is main constituent of chromosomes
Chromosomes
Located in nucleus containing DNA and proteins with genetic information
Cytoplasm
Jelly like Fluid that fills a cell where chemical reactions take place
organelle
Located in cell has one or more specific job to perform
Nucleus
Located in center of cell, has DNA, chromosomes and is the brain of cell
unicellular
A single cell able maintain life
multicellular
Organism made of millions of cells
cell theory
all organisms consist of cells, all cells come from pre-existing cells and living things grow by making new cells
Prokaryotic Cell
No nucleus, non-membrane bound organelles and is unicellular
Eukaryotic Cell
Membrane bound organelles, defined nucleus and defined chromosomes
order of cells life
cell, tissue, organs, system
types of tissue
connective, epidermis, muscle and nervous tissue
chloroplast
Only in plants and responsible for photosynthesis
synthesis
to manufacture or to make
diffusion
movement of net particles from a region of high concentration to a region of low concentration until equal
Osmosis
Special type of diffusion where only H2O molecules can move through a semipermeable membrane
Active transport
process of materials moved across the cell membrane with energy required
Passive Transport
Materials passed by diffusion requiring no energy
Rough endoplasmic reticulum
Produces proteins for cell which has ribosomes attached
Smooth endoplasmic reticulum
No ribosomes attached
ribosomes
synthesizes proteins for cell
