Cells

• Cells are the building blocks of life
• Cells come in many different shapes and sizes
• Some organisms are made up of a single cell and are called unicellular
• Organisms that are made of many cells are multicellular
• The nucleus contains genetic material (DNA) which controls how the cell works.
• Ribosomes make proteins, which are used to build new parts of the cell or repair damaged ones.
• Mitochondria produce energy from food molecules.
• Chloroplasts contain chlorophyll, which is needed for photosynthesis.

• The cytoplasm is the gel-like substance where the organelles are suspended
• Organelles are the specialised structures within cells that perform specific functions
• The cell membrane controls what enters and exits the cell
• Chloroplasts are responsible for photosynthesis
• The large central vacuole in plant cells stores water, nutrients, and waste products
• Animal cells have multiple, smaller vacuoles
• The organelles that are present in both animal and plant cells are the nucleus, mitochondria, cell membranes and cytoplasm
• Chlorophyll absorbs light energy for for photosynthesis
• mitosis is when a cell expands up to two times it's size, and then divides
