|
plasma membrane
|
bilipid/protein membrane
both animal.plant cells semi-permiable main part of cells homeostasis |
|
|
cytoplasm
|
75% water,12%protein
jelly lille material --> holds organelles in place |
|
|
nucleus
|
control all cell activities
enclosed in a bilipoio/protein membrane |
|
|
nucleolus
|
ball in the ball --> makes RNA and makes ribosomes
|
|
|
ribosomes
|
site of protein synthesis --> free in cytoplasm. others are attacked to the E.R
|
|
|
Endoplasmic Reticulum
|
series of channels throughout the cell.
transport materials through the cytoplasm. synthesis +storage of materials |
|
|
mitochondria
|
double membraned
aerobic respiration |
|
|
golgi complex
|
the UPS of cells. they package +transport
|
|
|
lysosomes
|
-contains digestive enzymes
-break down food and worn out cells |
|
|
vacuole
|
-storage bin for food, water +wastes
-plant cells-> large+ few # of cells animal cells--> very small=large # of cells |
|
|
centroilses
|
involved cell
-animal cells only. pair of them to each other |
|
|
chloroplast
|
plant cells only
-double memnbranded -have DNA recuperate on own -photosynthesis |
|
|
cell wall
|
plants cell only
-made of cellulose - cant be digested by animals |
|
|
cell theory
|
cells are basic units of structure+ function of living things;cells come from preexisting cells; supports unity of life
|
|
|
exceptions to cell theory
|
- first cell arose from non-existing cell
-viruses not composted of cells - mitochordina, chloroplasts |
|
|
scientists
|
a) van leuwenhoek- dutch naturalist,development of the first simple microscope,first drawings of microscope life
b)Hooke- englishman, compound microscope, box-like structures c) Brown- england,1831, structure nucleus d) Schleiden- plant tissues in germany. concluded that all plants were made up of cells E) Schwann- german, all animals were made up of cells F) virchow- 1858, all new cells must come from previously existing cells |
|
|
prokaryotes/eukaryotes
|
prokaryotes- do not contain nuclei
Eukaryotes- do contain nuclei |
|
|
difference between plant and animal cells
|
-animal cells don't have a cell wall
- plant cells have large vacuoles and animal cells have small vacuoles - animal cells have centrioles and plant cells do not |
|
|
organ of life cells
|
cells are the basic units of structure and function of living things
cells come from preexisting cells |
