- cells
- animal cells
- No large vacuole
- No chloroplast
- No cell wall
- Many irregular shapes
- plant cells
- cell wall
- gives celll support and shape
- large vacuole
- contains cell sap
- cell sap- water with various things dissolved it it
- contains cell sap
- chloroplast
- chlorophyll absorbs light so plant can make food
- process known as photosynthesis
- chlorophyll absorbs light so plant can make food
- regular shapes
- cell wall
- most cells contain
- cell membrane
- holds the cell together
- controls substances entering and leaving the cell
- nucleus
- contains chromosomes and genes
- controls how cell grows and works
- mitochondria
- where energy is released from food
- process known as respiration
- where energy is released from food
- cytoplasm
- where chemical reactions take place
- cell membrane
- specialized cells
- have special features to help them carry out a certain job
- sperm cell
- tail which moves so it can swim
- has many mitochondria to give it energy for swimming
- acrosome contains a digestive enzyme that makes a hole in the eggs cell membrane so the sperm can enter the egg
- nucleus contains chromosomes which carry genetic information that will be passed down to the off spring
- red blood cell
- no nucleus
- small
- flexible
- large numbers
- hemoglobin
- biconcave disc shape
- sperm cell
- have special features to help them carry out a certain job

- organs
- Transport
- 3 different ways
- diffusion
- osmosis
- Active transport
- diffusion
- high concentration to areas of low concentration.
- concentration gradient
- stops when particles are evenly concentrated
- difference in concentration
- particles are constantly moving
- high concentration to areas of low concentration.
- 3 different ways
- cells
