- Specialised Cells
- Plant Cells
- Palisade Cells
- They are found on the top of a leaf.
- They have a large surface area to help absorb lots of water and sunlight.
- They have lots of chloroplasts to absorb sunlight with.
- Root hair cell
- They are found in the root's hairs.
- They have a large vacuole to store water.
- They have thin cell walls to let water in easily.
- Xylem
- Xylem cells have a hollow inside to allow water to run through easily.
- They also have round rings in them to help strengthen the cells walls.
- They have a broken end wall so the water to come in and out.
- Palisade Cells
- Animal Cells
- Sperm Cell
- This cell has lots of mitochondria to power it along to the egg.
- It has lysosomes to digest its way into the egg.
- It has a tail to swim to the egg with.
- It carries the fathers DNA to the egg.
- Red Blood Cell
- It has no nucleus to make room for haemoglobin and therefore more oxygen molecules.
- It has a dip in the middle to carry oxygen molecules in.
- Sperm Cell
- Plant Cells
- Key Words
- Nucleus
- It controls the cell and contains DNA.
- Mitochondria
- This organelle releases energy when you breath out.
- Cell Specialisation
- When a cell is specially adapted to doing a certain job/function.
- Diffusion
- The movement of particles from a high concentration to a low concentration.
- Ribosome
- The cell structure that produces proteins.
- Nucleus
- More Key Words.
- Cell Membrane.
- This controls what goes in and out of the cell.
- Cytoplasm.
- The liquid inside the cell where most chemical reactions take place. It suspends everything in the cell inside it.
- Cell Wall.
- It is only found in plant cells and keeps the cell supported and upright.
- Chloroplasts.
- These are only found in plant cells and are used to do photosynthesis.
- Plasmid.
- A circular strand of DNA found in bacteria cells.
- Cells
- The smallest functional unit of an organism.
- Tissues
- A group of similar cells working together to perform a function.
- Organs
- A group of tissues working together to perform a function.
- Organ System
- A group of organs working together to perform a function.
- Eukaryotic cells
- Cells that contain their genetic material in a nucleus. Such as plant and animal cells.
- Prokaryotic
- Cells that don't have a nucleus and the DNA floats free in the cytoplasm. Such as bacteria cells.
- Genes
- Section of DNA that contains the information for a characteristic
- Cell Membrane.
