what are the five characteristics of living things
reproduce, produce waste, grow, need energy, responds and adapts to their environment, made up of cells,
what was aristotles technology, technique, and achievement
he did not do any experimentation and he acheived spontaneous generation
who created spontaneous generation
aristotle
what is spontaneous generation?
organisms appear from non-living things
what were Francisco Redis’s technology, technique, and achievements?
he manipulated access to flies to test spontaneous generation and he showed maggots come from flies not from meat
what were Louis pasteur technology, techniques, and achievements?
he used flasks with swan-shaped necks to manipulate the access of dust to broth, he achieved biogenesis
who achieved and came up with biogenesis?
Louis Pasteur
What were Robert Hookes’s technology or techniques,and achievements
he used a three-lens microscope to look at a cork and he discovered and achieved that magnification was great enough to see individual “cells”
What did Antoni can Leeuwenhoek achieve?
he was able to see moving micro-organisms
what were Antoni van Leeuwenhoek’s technology or technique?
he used a single lens system similar to a magnify glass
what did M.J. Schleiden, T.S. Schwann, and Rudolf Virchow achieve?
the development of the cell theory
how dod Schleiden, Schwann, and Virchow develop the cell theory? what was their technology or tenchique
Microscope studyies of plant tissues(Schleiden), animal tissues(Schwann), and diseased tissues(Virchow)
what are the three components of cell theory
• all organisms are composed of one or more cells • cells are the smallest unit of life • all cells come from pre-existing cells through cell division
what are the processes of a cell
-nutrient intake - movement - growth - response to stimuli - gas exchange - waste removal - reproduction
prokaryotic vs eukaryotic cells
plants, animals, and fungi are eukaryotic, and bacteria and archea are prokaryotic
Parts of an animal cell
cell membrane, cytoplasm, nucleus, endoplasmic reticulum (ER), Ribosomes, Golgi apparatus, lysosomes, mitochondria
parts of a plant cell
cell membrane, cytoplasm, nucleus, endoplasmic reticulum (ER), Ribosomes, Golgi apparatus, lysosomes, mitochondria, cell wall, chloroplasts, vacuole
what is the cell membrane:
flexible boundary that controls the movement of materials in and out of the cell, important for cell communication
what is cytoplasm
jelly like material found throughout the cell in whicj organelles are suspended, it contains water and nutrients
what is the nucleus
controls all cellular activities, where DNA is stored
what is the endoplasmic reticulum (ER)
a series of interconnected tubes that branch from the nucleus, there are two types; smooth ER and rough ER
what does the smooth ER do
makes lipids(fat) for delivery out of the cellq
what does the rough ER do
makes proteins for delivery out of the cell, embedded with ribosomes which help create the proteins
what are ribosomes
may be embedded in the rough ER or in the cytoplasm, translates mRNA from nucleus into sequences of smino acids(proteins)
