Study Notes
Respiration
- Respiration is the release of energy from food to carry out life processes
- Respiration is necessary for all living things
- Anaerobic respiration occurs without oxygen in certain cells
- Aerobic respiration occurs with oxygen in both cells
Growth
- Growth is the change in size, mass, and number of all living things
Sensitivity
- The ability of all living things to sense changes in the environment
Reproduction
- The ability of all living things to generate offspring
- Sexual reproduction involves the fusing of sex cells
- Asexual reproduction only involves one parent
Plant Cell Diagram
- The cell wall is permeable and contains cellulose
- Chloroplasts have a double membrane and an internal membrane, contain chlorophyll and photosynthetic enzymes
- The vacuole is a large, membrane-bound compartment containing sugars, minerals, and waste products
- The cell membrane controls what enters and leaves the cell
- The cytoplasm supports the organelles and is the site of many chemical reactions
Plant & Animal Cells
- Plant and animal cells contain organelles which are specialized cells that carry out vital functions
- Organelles are located in the cytoplasm, which is surrounded by one or more membranes
- Both types of cells contain smooth and rough endoplasmic reticulum, nucleus, cytoplasm, ribosomes, cell membrane and mitochondria
What are Cells?
- Cells are the basic fundamental units of living things
Hierarchy of Biological Organization
- The order of biological organization from smallest to largest is: cells, tissues, systems, body
Characteristics of Cells
- Cells contain all 7 traits of living things
- Some cells are unicellular, containing only one cell
- Others are multicellular, containing multiple cells
Cell Structure Overview
- Ribosomes are small organelles
- The cell membrane is a permeable layer containing proteins and liquids outside of the cell
- The nucleus is surrounded by a double membrane and contains chromatin threads
- Chromatin threads contain DNA
- The rough endoplasmic reticulum is a network of tubules through the cytoplasm that has ribosomes attached
- The smooth endoplasmic reticulum does not have ribosomes attached
